Improve Arthritis with Qigong

 

By John M. de Castro, Ph.D.

 

“Qigong techniques are simple and do not need to be carried out precisely to bring about its great benefits. Qigong practice is known for preventing disease, strengthening immunity and producing better health and well-being. However it is under-appreciated, even in China, that Qigong therapy can be effective for relieving pain and treating arthritis.” – Kellen Chia

 

Arthritis is a chronic disease that most commonly affects the joints. There are over 100 different types of arthritis. Depending on the type of arthritis symptoms may include pain, stiffness, swelling, redness, and decreased range of motion. It affects an estimated 52.5 million adults in the United States. It is associated with aging as arthritis occurs in only 7% of adults ages 18–44, while 30% adults ages 45–64 are affected, and 50% of adults ages 65 or older. The pain, stiffness, and lack of mobility associate with arthritis produce fatigue and markedly reduce the quality of life of the sufferers. Arthritis can have very negative psychological effects diminishing the individual’s self-image and may lead to depression, isolation, and withdrawal from friends and social activities Arthritis reduces the individual’s ability to function at work and may require modifications of work activities which can lead to financial difficulties. It even affects the individual’s physical appearance. In addition, due to complications associated with rheumatoid arthritis, particularly cardiovascular disease, the lifespan for people with rheumatoid arthritis may be shortened by 10 years.

 

It is obvious that there is a need for a safe and effective treatment to help rheumatoid arthritis sufferers cope with the disease and its consequences. Increasing exercise has been shown to increase flexibility and mobility but many form of exercise are difficult for the arthritis sufferer to engage in and many drop out. But all that may be needed is gentle movements of the joints. Qigong or Tai Chi training are designed to enhance and regulate the functional activities of the body through regulated breathing, mindful concentration, and gentle movements. They have been shown to have many physical and psychological benefits, especially for the elderly. Because They are not strenuous, involving slow gentle movements, and are safe, having no appreciable side effects, they are appropriate for an elderly population. So, it would seem that Qigong or Tai Chi practice would be well suited to treat arthritis in seniors.

 

In today’s Research News article “Qigong Exercise and Arthritis.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5750595/ ), Marks reviewed and summarized the published research on the effectiveness of Qigong practice for the treatment of arthritis. He found that Qigong practice produced significant improvements in the musculoskeletal system including increased strength, joint flexibility, posture, balance motor function, and motor coordination, and improvements in quality of life and cognitive function. In addition, the research reported decreased pain, fatigue, and blood pressure and improved immune function, metabolic function, circulation, aerobic capacity, and reduced falls, improved psychological health, mood, and sleep.

 

These are impressive results. Scientific research suggests that Qigong practice produces  widespread improvements in mental and physical health in arthritis sufferers. In addition, it is inexpensive, convenient, appropriate for individuals of all ages and health condition and is safe to practice, making it an almost ideal treatment for the symptoms of arthritis.

 

So, improve arthritis with Qigong.

 

“Qigong focuses on relaxing the body, which over time, allows the joints and muscles to loosen up, improving the circulation of fluids and blood. The practice focuses on rebuilding overall health and strengthening the spirit, while encouraging one to change the way one looks at life in general, and at the illness affecting you.” – 1MD

Study Summary

 

Ray Marks. Qigong Exercise and Arthritis. Medicines (Basel) 2017 Dec; 4(4): 71. Published online 2017 Sep 27. doi: 10.3390/medicines4040071

 

Abstract

Background: Arthritis is a chronic condition resulting in considerable disability, particularly in later life. Aims: The first aim of this review was to summarize and synthesize the research base concerning the use of Qigong exercises as a possible adjunctive strategy for promoting well-being among adults with arthritis. A second was to provide related intervention directives for health professionals working or who are likely to work with this population in the future. Methods: Material specifically focusing on examining the nature of Qigong for minimizing arthritis disability, pain and dependence and for improving life quality was sought. Results: Collectively, despite almost no attention to this topic, available data reveal that while more research is indicated, Qigong exercises—practiced widely in China for many centuries as an exercise form, mind-body and relaxation technique—may be very useful as an intervention strategy for adults with different forms of painful disabling arthritis. Conclusion: Health professionals working with people who have chronic arthritis can safely recommend these exercises to most adults with this condition with the expectation they will heighten the life quality of the individual, while reducing pain and depression in adults with this condition.

Be Mindful for Improved Psychological Health

Be Mindful for Improved Psychological Health

 

By John M. de Castro, Ph.D.

 

“We’ve seen this in the clinical domain for many years. People, in concert with their physicians… actually going off their medications for pain, for anxiety, for depression, as they begin to learn the self-regulatory elements of mindfulness. They discover that the things that used to be symptomatically problematic for them are no longer arising at the same level.” – Jon Kabat-Zinn

 

Mindfulness training has been shown through extensive research to be effective in improving the physical and psychological condition of otherwise healthy people and also treating the physical and psychological issues of people with illnesses and particularly with the physical and psychological reactions to stress. Techniques such as Mindfulness-Based Stress Reduction (MBSR) and Mindfulness-Based Cognitive Therapy (MBCT) as well as Yoga practice and Tai Chi or Qigong practice have been demonstrated to be particularly effective. This has led to an increasing adoption of these mindfulness techniques for the health and well-being of both healthy and ill individuals.

 

In fact, the degree of mindfulness, inherent in the individual, without training, known as dispositional mindfulness, has been shown to be associated with the degree of mental and physical health. In today’s Research News article “Dispositional Mindfulness and Psychological Health: a Systematic Review.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5770488/ ), Tomlinson and colleagues review and summarize the published scientific research regarding the relationship of dispositional mindfulness to psychological health. They identified 93 research studies that found three different areas of relationship.

 

They report that the published research found that dispositional mindfulness was associated with improved psychopathological symptoms. The published research report that the higher the individuals’ levels of dispositional mindfulness the lower the levels of depression, anxiety, disordered eating, Post-Traumatic Stress Disorder (PTSD) symptoms, and Borderline Personality Disorder (DPD) symptoms.

 

They report that the published research found that dispositional mindfulness was associated with improved cognitive performance. It was found that that the higher the individuals’ levels of dispositional mindfulness the lower the levels of avoidant coping strategies e.g. procrastination, rumination, impulsivity, catastrophizing and neuroticism, and the higher the levels of executive function (high level thinking).

 

Finally, they report that dispositional mindfulness was associated with improved emotional control. It was reported that the higher the individuals’ levels of dispositional mindfulness the lower the levels of perceived stress, emotional distress, and higher levels of emotion regulation, emotional stability, psychological well-being, and recovery following stressful conditions.

 

This review of the published research suggests that being generally mindful (dispositional mindfulness) is associated with psychological health and well-being. The problem with dispositional characteristics is that they cannot be manipulated as they are relatively stable characteristics of the individual. They can only be correlated with other characteristics. As such, it is impossible to conclude causal relationships between dispositional mindfulness and psychological health. It is equally likely that psychological health produces dispositional mindfulness, that dispositional mindfulness produces psychological health, or that a third factor causes both.

 

Manipulative research, producing changes in the short-term state of mindfulness, however, demonstrates that increases in mindfulness cause improvements in psychological well-being. So, it is likely that the observed relationships of dispositional mindfulness and psychological health are the result of dispositional mindfulness causing improved emotional and cognitive function and thereby reduced psychopathology and improved mental health.

 

So, be mindful for improved psychological health.

 

“A great deal of research has documented physical health benefits of mindfulness, such as an improved immune system, lower blood pressure, and better sleep. Mindfulness has also been linked to mental health benefits, such as reduced stress and anxiety, and improved concentration and focus, less emotional reactivity.” – American Psychiatric Association

Abstract

Interest in the influence of dispositional mindfulness (DM) on psychological health has been gathering pace over recent years. Despite this, a systematic review of this topic has not been conducted. A systematic review can benefit the field by identifying the terminology and measures used by researchers and by highlighting methodological weaknesses and empirical gaps. We systematically reviewed non-interventional, quantitative papers on DM and psychological health in non-clinical samples published in English up to June 2016, following the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. A literature search was conducted using PsycINFO, PubMED, Medline and Embase, and 93 papers met the inclusion criteria. Within these, three main themes emerged, depicting the relationship between DM and psychological health: (1) DM appears to be inversely related to psychopathological symptoms such as depressive symptoms, (2) DM is positively linked to adaptive cognitive processes such as less rumination and pain catastrophizing and (3) DM appears to be associated with better emotional processing and regulation. These themes informed the creation of a taxonomy. We conclude that research has consistently shown a positive relationship between DM and psychological health. Suggestions for future research and conceptual and methodological limitations within the field are discussed.

Improve Cognition in the Elderly with Tai Chi

 

By John M. de Castro, Ph.D.

 

“Tai Chi has consistent, small effects on improving cognitive performance in both healthy older adults and older adults with some cognitive impairment.” – PM Wayne

 

The aging process involves a systematic progressive decline of the body and the brain. Every system in the body deteriorates including cognitive function (thinking ability) and motor function with a decline in strength, flexibility, and balance. It is inevitable. In addition, many elderly experience withdrawal and isolation from social interactions. There is some hope as there is evidence that these declines can be slowed. For example, a healthy diet and a regular program of exercise can slow the physical and cognitive decline of the body with aging. Also, contemplative practices such as meditation, yoga, and tai chi or qigong have all been shown to be beneficial in slowing or delaying physical and mental decline.

 

Tai Chi has been practiced for thousands of years with benefits for health and longevity. Tai Chi training is designed to enhance function and regulate the activities of the body through regulated breathing, mindful concentration, and gentle movements. Only recently though have the effects of Tai Chi practice been scrutinized with empirical research. But, it has been found to be effective for an array of physical and psychological issues. Tai Chi has been shown to help the elderly improve attention, balance, reducing falls, arthritis, cognitive function, memory, and reduce age related deterioration of the brain. Because Tai Chi is not strenuous, involving slow gentle movements, and is safe, having no appreciable side effects, it is appropriate for all ages including the elderly and for individuals with illnesses that limit their activities or range of motion.

 

In today’s Research News article “Effects of tai chi on cognition and instrumental activities of daily living in community dwelling older people with mild cognitive impairment.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5797349/ ), Siu and Lee examine the effectiveness of Tai Chi practice for elderly individuals with mild cognitive impairment. They recruited elderly individuals (> 60 years of age) with mild cognitive impairment from 4 community centers for the elderly. Participants from two community centers were randomly assigned to a no-treatment control condition or to receive 16 weeks of Tai Chi training for 1-hour twice a week. They were measured before and after training for cognitive ability and daily living activities; including using telephone, shopping, preparing food, doing house-keeping and laundry, using transportation, managing finances, handling medication, and doing handyman work.

 

They found that the Tai Chi practice group compared to baseline and the control group had significant improvements in cognitive ability and in the performance of daily activities. These are important findings. With an aging population, the maintenance of ability to perform daily activities may reduce the burden and cost of caregivering. In addition, the improvements in cognitive function may reduce the incidence of dementia and allow for better quality of life in the elderly. Importantly, these benefits can be produced with a convenient, inexpensive, safe, and fun social activity.

 

So, improve cognition in the Elderly with Tai Chi.

 

“A comparison of the effects of regular sessions of tai chi, walking, and social discussion, has found tai chi was associated with the biggest gains in brain volume and improved cognition.” – Fiona MsPherson

Study Summary

 

Mei-yi Siu, Diana T. F. Lee. Effects of tai chi on cognition and instrumental activities of daily living in community dwelling older people with mild cognitive impairment. BMC Geriatr. 2018; 18: 37. Published online 2018 Feb 2. doi: 10.1186/s12877-018-0720-8

 

Abstract

Background

Cognitive impairment places older adults at high risk of functional disability in their daily-life activities, and thus affecting their quality of life. This study aimed to examine the effects of Tai Chi on general cognitive functions and instrumental activities of daily living (IADL) in community-dwelling older people with mild cognitive impairment (MCI) in Hong Kong.

Methods

The study adopted a multi-site nonequivalent control-group pretest-posttest design. 160 community-dwelling older people, aged ≥60, with MCI, from four community elderly centers participated in the study. The intervention group (IG, n = 80) received training in the Yang-style simple form of Tai Chi, at a frequency of two lessons per week for 16 weeks. Each lesson lasted for one hour. The control group (CG, n = 80) had no treatment regime and joined different recreational activity groups in community centers as usual within the study period. Outcome measures included measures of global cognitive status and IADL. The Chinese version of the Mini-Mental State Examination (CMMSE) was used for global cognitive assessment. The Hong Kong Chinese version of Lawton’s Instrumental Activities of Daily Living (IADL-CV) was used to assess the participants’ IADL levels. General Estimating Equations (GEE) was used to examine each of the outcome variables for the two groups at the two study time points (the baseline and at the end of the study). Meanwhile, minimum detectable change (MDC) was calculated to estimate the magnitude of changes required to eradicate the possibility of measurement error of outcome measures.

Results

Seventy four participants in the IG and 71 participants in the CG completed the study. With adjustments for differences in age, education, marital status and living conditions, the findings revealed that the participants in the IG scored significantly better on the CMMSE test (P = 0.001), and the instrumental ADL questionnaire (P = 0.004). However, those scores changes did not exceed the limits of the respective MDCs in the study, the possibility of measurement variation due to error could not be excluded.

Conclusion

Tai Chi may be an effective strategy to enhance cognitive health and maintain functional abilities in instrumental ADL in older people with MCI.

Slow Mental Decline in the Elderly with Tai Chi

Slow Mental Decline in the Elderly with Tai Chi

 

By John M. de Castro, Ph.D.

 

“improvement of heart function combined with increased muscular power meant that the martial art should be considered the preferred technique for elderly people to maintain good health.” – The Telegraph

 

We celebrate the increasing longevity of the population. But, aging is a mixed blessing. The aging process involves a systematic progressive decline of the body and the brain. Every system in the body deteriorates including cognitive function (thinking ability) and motor function with a decline in strength, flexibility, and balance. It is inevitable. In addition, many elderly experience withdrawal and isolation from social interactions. There is some hope as there is evidence that these declines can be slowed. For example, a healthy diet and a regular program of exercise can slow the physical and cognitive decline of the body with aging. Also, contemplative practices such as meditation, yoga, and tai chi or qigong have all been shown to be beneficial in slowing or delaying physical and mental decline.

 

Tai Chi has been practiced for thousands of years with benefits for health and longevity. Tai Chi training is designed to enhance function and regulate the activities of the body through regulated breathing, mindful concentration, and gentle movements. Only recently though have the effects of Tai Chi practice been scrutinized with empirical research and found to be effective for an array of physical and psychological issues. Tai Chi has been shown to help the elderly improve attention, balance, reducing falls, arthritis, cognitive function, memory, and reduce age related deterioration of the brain. Because Tai Chi is not strenuous, involving slow gentle movements, and is safe, having no appreciable side effects, it is appropriate for all ages including the elderly and for individuals with illnesses that limit their activities or range of motion.

 

In today’s Research News article “Tai Chi Improves Cognition and Plasma BDNF in Older Adults with Mild Cognitive Impairment: A Randomized Controlled Trial.”  Sungkarat and colleagues recruited elderly participants with mild cognitive impairments and randomly assigned them to either receive educational instruction related to cognitive impairment and fall prevention or practice Tai Chi at home guided by a 50-minute video, 3 times per week, for 6 months. They were measured at the beginning and end of training for cognitive performance, including memory, visuospatial ability, and executive function, and plasma markers for inflammation and neuroprotection, including plasma BDNF, TNF-α, and IL-10 levels.

 

They found that compared to baseline and control participants, the elderly who practiced Tai Chi had significantly improved levels of cognitive function, including improvements in memory and thinking ability (executive function). In addition, Tai Chi practice was found to significantly increase the levels of brain-derived neurotrophic factor (BDNF). BDNF is a neurotrophic factor that works to protect the brain from deterioration and promote the growth of brain cells. Hence, they found that Tai Chi practice reduces cognitive decline with aging and increases neuroprotection.

 

The cognitive decline with aging has been associated with degeneration of neural tissues. On the other hand, mindfulness practices have been found to change the brain and protect it against age related decline. The present results add further evidence that mindfulness practices, Tai Chi  in particular, improves memory and cognitive performance and promotes neuroprotection in the elderly. The attractiveness of the low intensity, low cost, convenient, and socially fun nature of Tai Chi practice makes it a great treatment for the prevention of age related decline.

 

So, slow mental decline in the elderly with Tai Chi.

Abstract

Background. Effects of Tai Chi (TC) on specific cognitive function and mechanisms by which TC may improve cognition in older adults with amnestic mild cognitive impairment (a-MCI) remain unknown. Objective. To examine the effects of TC on cognitive functions and plasma biomarkers (brain-derived neurotrophic factor [BDNF], tumor necrosis factor-α [TNF-α], and interleukin-10 [IL-10]) in a-MCI. Methods. A total of 66 older adults with a-MCI (mean age = 67.9 years) were randomized to either a TC (n = 33) or a control group (n = 33). Participants in the TC group learned TC with a certified instructor and then practiced at home for 50 min/session, 3 times/wk for 6 months. The control group received educational material that covered information related to cognition. The primary outcome was cognitive performance, including Logical Memory (LM) delayed recall, Block Design, Digit Span, and Trail Making Test B minus A (TMT B-A). The secondary outcomes were plasma biomarkers, including BDNF, TNF-α, and IL-10. Results. At the end of the trial, performance on the LM and TMT B-A was significantly better in the TC group compared with the control group after adjusting for age, gender, and education (P < .05). Plasma BDNF level was significantly increased for the TC group, whereas the other outcome measures were similar between the 2 groups after adjusting for age and gender (P < .05). Conclusions. TC training significantly improved memory and the mental switching component of executive function in older adults with a-MCI, possibly via an upregulation of BDNF.

The Variety of Meditation Experiences

The Variety of Meditation Experiences

 

By John M. de Castro, Ph.D.

 

“One can have almost any type of physical sensation during meditation in any area of the body. . .  The ticklish sensation in your heart just means that some normalization is occurring there, allowing for a more full expression of your emotions. The sense of anxiety or fear is a by-product of that clearing process.” – Depak Chopra

 

Meditation is a wonderful practice that has many documented beneficial effects on mental, physical and spiritual health. For the most part, people have positive experiences during meditation, but it is not all positive. People begin meditation with the misconception that meditation will help them escape from their problems. Nothing could be further from the truth. In fact, meditation does the exact opposite, forcing the meditator to confront their issues. In meditation, the practitioner tries to quiet the mind. But, in that relaxed quiet state, powerful, highly emotionally charged thoughts and memories sometimes emerge.

 

Many practitioners never experience these issues or only experience very mild states. There are, however, few systematic studies of the extent of negative experiences. In general, the research has reported that unwanted (negative) experiences are quite common with meditators, but for the most part, are short-lived and mild. There is, however, a great need for more research into the nature of the experiences that occur during meditation.

 

In today’s Research News article “The varieties of contemplative experience: A mixed-methods study of meditation-related challenges in Western Buddhists.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5443484/ ),

Lindahl and colleagues recruited experienced adult meditation practitioners and teachers from a variety of different traditions. Meditators were excluded if they had a history of unusual psychological experiences prior to learning meditation. They conducted extensive semi-structured interviews that consisted of open-ended questions regarding meditation-related experiences. Interviews with the participants were conducted either in person, by videoconferencing, or by telephone. Transcripts of the interviews were then subjected to qualitative data analysis focusing on challenging or difficult experiences.

 

They found that most practitioners had experienced at least some challenging experiences. 29% encountered challenges in their first year of practice while 45% encountered them in their first 10 years. For 73% of the practitioners, challenging experiences were associated with meditation retreats, while the rest were associated with daily practice. The more meditation per day the greater the likelihood of negative experiences with only 25% who practiced for 30-60 minutes per day having negative experiences, 34% who practiced 1-9 hours per day, and 41% who practiced over 10 hours per day. One of the most striking findings was the duration of negative experiences. They were not brief or fleeting. In fact, on average they were reported to persist from 1 to 3 years and as long as 10 years.

 

Thematic content analysis of the transcripts revealed 59 different categories of experiences that occurred in 7 higher order domains; cognitive, perceptual, affective, somatic, conative, sense of self, and social. 73% of practitioners had experiences falling into at least 6 domains.

 

The Cognitive Domain consisted in “Changes . . . to mental functioning, including the frequency, quality and content of thoughts, as well as . . . planning, decision-making and memory.” Most experiences in this domain were pleasant but unpleasant experiences also occurred including inability to concentrate for extended periods, problems with memory, the disintegration of conceptual meaning structures, “mind racing,” vivid imagery, and delusional, irrational, or paranormal beliefs.

 

The Perceptual domain consisted of ”changes to any of the five senses: vision, hearing, smell, taste and somatosensory processing” and interoception and proprioception. Unpleasant experiences in this domain included hypersensitivity to stimuli, illusions, hallucinations, dissolution of perceptual objects, distortions in time and space, and sensations appearing dreamlike, as if in a fog.

 

The Affective domain consisted of changes in the type, frequency, or intensity of emotions. For many the affective experiences were pleasant including bliss and euphoria, sometimes verging on mania. But, unpleasant experiences were very frequent and involved both increased and decreased emotionality including anxiety fear, panic, re-experiencing trauma, irritability, anger, and paranoia with 82% reporting it. For some flat affect occurred with a loss of swings in emotion.

 

The Somatic domain consisted of “changes in bodily functioning or physiological processes.” Unpleasant experiences in this domain included sleep disruption, feelings of pressure, tension, and hot and cold, electricity like voltages or currents through the body sometimes resulting in involuntary movements.

 

The Conative domain consisted of “changes in motivation or goal-directed behaviors.” Unpleasant experiences in this domain included loss of desire for previously enjoyed activities and loss of motivation to achieve goals.

 

The Sense of Self domain consisted of “changes in how a practitioner conceives of himself or herself over time.” Unpleasant experiences in this domain including a dissolution of boundaries between the individuals and others and the environment, loss of a sense of ownership of thoughts, emotions and agency (the doer), and loss of a sense of self entirely.

 

The Social domain consisted of “changes in interpersonal activities or functioning, including level of engagement, quality of relationships, or periods of conflict, isolation or withdrawal.” Unpleasant experiences in this domain included problems re-integrating into society after a retreat or intensive practice, impaired functioning at work or with family, and doubt and loss of faith. In fact, many of the negative experiences bled over into everyday life affecting all social interactions.

 

These findings need to be kept in perspective as most experience with meditation are pleasant and positive and even the negative experiences are mainly brief and manageable. But the results emphasize that it’s not all what people are led to believe. It can turn unpleasant or even ugly. It is important that this be taught and managed in the meditation community. In the monasteries this is well understood and managed. But in the secular world, these negative experiences are rarely taught, understood, reacted to properly, or managed. For many negative experiences can lead to stopping practice, but for others they can lead to grave psychological harm. It is important that the practitioner be made aware of these possible experiences before they begin, so they are better able to understand them a handle them astutely.

 

Meditation should not be engaged in blindly without proper instruction. It can produce great benefit but sometimes great harm. In order to maximize the benefits and minimize the harm proper education and management is needed.

 

“Emotions that come up during meditation represent one of two things: 1) undigested past negative emotions that are rising up to be processed, or 2) a present-moment experience of raw emotion from something happening now, which can be positive or negative. Either way, it can make for an uncomfortable meditation and is one of the most common reasons people stop meditating.” – Trista Thorp

Abstract

Buddhist-derived meditation practices are currently being employed as a popular form of health promotion. While meditation programs draw inspiration from Buddhist textual sources for the benefits of meditation, these sources also acknowledge a wide range of other effects beyond health-related outcomes. The Varieties of Contemplative Experience study investigates meditation-related experiences that are typically underreported, particularly experiences that are described as challenging, difficult, distressing, functionally impairing, and/or requiring additional support. A mixed-methods approach featured qualitative interviews with Western Buddhist meditation practitioners and experts in Theravāda, Zen, and Tibetan traditions. Interview questions probed meditation experiences and influencing factors, including interpretations and management strategies. A follow-up survey provided quantitative assessments of causality, impairment and other demographic and practice-related variables. The content-driven thematic analysis of interviews yielded a taxonomy of 59 meditation-related experiences across 7 domains: cognitive, perceptual, affective, somatic, conative, sense of self, and social. Even in cases where the phenomenology was similar across participants, interpretations of and responses to the experiences differed considerably. The associated valence ranged from very positive to very negative, and the associated level of distress and functional impairment ranged from minimal and transient to severe and enduring. In order to determine what factors may influence the valence, impact, and response to any given experience, the study also identified 26 categories of influencing factors across 4 domains: practitioner-level factors, practice-level factors, relationships, and health behaviors. By identifying a broader range of experiences associated with meditation, along with the factors that contribute to the presence and management of experiences reported as challenging, difficult, distressing or functionally impairing, this study aims to increase our understanding of the effects of contemplative practices and to provide resources for mediators, clinicians, meditation researchers, and meditation teachers.

Improve Thinking in Older Adults with Tai Chi

 

By John M. de Castro, Ph.D.

 

“It may be no surprise that Tai Chi has physical benefits – after all, it involves movement. Well, did you know that Tai Chi may also have mental benefits? Specifically, . . . significant increases in the brain size, memory and thinking of older adults who practiced Tai Chi compared to other groups in the study.” – Tai Chi for Health

Tai Chi has been shown to help the elderly improve attention, balance, reducing falls, arthritis, cognitive function, memory, and reduce age related deterioration of the brain. Because Tai Chi is not strenuous, involving slow gentle movements, and is safe, having no appreciable side effects, it is appropriate for all ages including the elderly and for individuals with illnesses that limit their activities or range of motion.

 

In today’s Research News article “The benefits of Tai Chi and brisk walking for cognitive function and fitness in older adults.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5652256/ ), Ji and colleagues recruited health adults aged 60 to 72 years. Participants who engaged in Tai Chi, brisk walking, or no exercise were compared on cognitive performance. They were measured with the Stroop test where names of colors were presented in colors different from the word, e.g. the word RED appears in a blue color. The participants are asked to report the word (naming) or the color of the word ignoring the meaning of the word itself (inhibition) or switch back and forth (Executive function). They were also measured with a digit comparison task in which they were presented with two numbers and asked to identify which was larger. The numbers were presented either simultaneously (non-delay) or delayed by 1.5 seconds (delay).

 

They found that both the Tai Chi and brisk walking groups were superior on the tasks than the control group. But, the Tai Chi group responded faster on the Stroop naming and executive conditions and were more accurate on the inhibition condition than the brisk walking group. In addition, the Tai Chi group responded faster than the brisk walking group on the delayed digit comparison condition. This suggests that the both Tai Chi and brisk walking participation improves cognitive performance in older adults but that Tai Chi dose so better than brisk walking.

 

The interpretation of the results needs to be qualified as there was no active manipulations of the activity conditions. Older adults who already participated in these activities were simply compared. Hence, it is impossible to conclude causation. It is conceivable that people who chose to participate in Tai Chi may be different people with better cognitive ability than people who chose brisk walking. The observed differences, then, may be due to the typ of people whoe chose an activity rather than the effects of the activity.

 

But, taken at face value the results suggest the Tai Chi, which places greater cognitive demands on the practitioner than brisk walking, has greater cognitive benefits. Given the progressive inevitable decline with aging in cognitive ability, methods that can slow or delay the decline are valuable. Tai Chi would appear to be an almost ideal method to improve fitness and balance, reducing falls, in the elderly and improve cognitive performance.

 

So, improve thinking in older adults with tai chi.

 

“Epidemiologic studies have shown repeatedly that individuals who engage in more physical exercise or are more socially active have a lower risk of Alzheimer’s disease. The current findings suggest that this may be a result of growth and preservation of critical regions of the brain affected by this illness.” – James Mortimer

Study Summary

 

Ji, Z., Li, A., Feng, T., Liu, X., You, Y., Meng, F., … Zhang, C. (2017).. PeerJ, 5, e3943. http://doi.org/10.7717/peerj.3943

 

Abstract

The purpose of this study was to investigate the benefits of exercises with different cognitive demands for cognitive functions (Executive and non-Executive) in healthy older adults. A cross-sectional design was adopted. In total, 84 healthy older adults were enrolled in the study. They were categorized into the Tai Chi group (TG), the brisk walking group (BG) or the control group (CG). Each participant performed the Stroop task and a digit comparison task. The Stroop task included the following three conditions: a naming condition, an inhibition condition and an executive condition. There were two experimental conditions in the digit comparison task: the non-delay condition and the delay condition. The results indicated that participants of the TG and BG revealed significant better performance than the CG in the executive condition of cognitive tasks and fitness. There was no significant difference of reaction time (RT) and accuracy rate in the inhibition and delay conditions of cognitive tasks and fitness between the TG and BG. The TG showed shorter reaction time in the naming and the executive conditions, and more accurate in the inhibition conditions than the BG. These findings demonstrated that regular participation in brisk walking and Tai Chi have significant beneficial effects on executive function and fitness. However, due to the high cognitive demands of the exercise, Tai Chi benefit cognitive functions (Executive and non-Executive) in older adults more than brisk walking does. Further studies should research the underlying mechanisms at the behavioural and neuroelectric levels, providing more evidence to explain the effect of high-cognitive demands exercise on different processing levels of cognition.

Reduce Mild Aging Cognitive Decline with Yogic Meditation

 

By John M. de Castro, Ph.D.

 

“The healthier and more active one’s lifestyle, the more likely he or she will maintain cognitive performance over time. And meditation may be a key ingredient for ensuring brain health and maintaining good mental performance.” – Grace Bullock

 

The aging process involves a systematic progressive decline in every system in the body, the brain included. This includes our mental abilities which decline with age including impairments in memory, attention, and problem solving ability. It is inevitable and cannot be avoided. But, there is some hope for age related cognitive decline, as there is evidence that it can be slowed. There are some indications that physical and mental exercise can reduce the rate of cognitive decline and lower the chances of dementia. For example, contemplative practices such as meditation, yoga, and Tai Chi and Qigong have all been shown to be beneficial in slowing or delaying physical and mental decline with aging. Mindfulness practices have been shown to improve cognitive processes.

 

Yoga is a mindfulness practice that is safe and applicable to the elderly. So, it could potentially be an ideal practice for the slowing of age related cognitive decline. In today’s Research News article “A randomized controlled trial of Kundalini yoga in mild cognitive impairment.” See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5540331/, Eyre and colleagues recruited elderly (older than 55 years of age, average 68) with a mild degree of cognitive impairment and randomly assigned them to a 12 week, 60 minutes once a week, standard memory enhancement treatment or to yogic meditation practice, Kundalini Yoga. Daily homework was assigned. Kundalini Yoga includes meditation, breathing exercises, and mantra practice. The participants were measured before and after training and 12 weeks later for memory ability, executive function, resilience, physical and cognitive symptoms, neuropsychiatric symptoms, illness, apathy, and mood including depression.

 

They found that following training both the yoga and memory enhancement groups had significant improvements in memory and apathy and these improvements were still present 12 weeks after the end of training. In contrast, only the Kundalini Yoga group had significant improvements in depression, resilience, and executive function, including cognitive flexibility, response inhibition, and semantic fluency. Hence, both groups improved in memory and apathy, but only the Kundalini Yoga group also improved in mood, resilience, and higher-level thinking (cognitive function).

 

These are exciting findings suggesting the Kundalini Yoga is a safe and effective treatment that for age related declines in cognitive function, depression, apathy, and memory and improves stress resilience. It has been demonstrated that mindfulness training produces a wide variety of benefits for the elderly including mood, memory and cognitive improvements. So, Kundalini Yoga can be added to the list of effective mindfulness trainings for the elderly.

 

This was an excellent study as the comparison condition was the current “gold standard” of treatment for mild cognitive impairment in the elderly, memory enhancement training. Yet, Kundalini Yoga was significantly more beneficial. The improvement in stress resilience is important and may underlie some of the other benefits of the Kundalini Yoga training. Aging can produce considerable economic, physical, psychological, and social stresses. Improvement in the ability to withstand the effects of these stresses should be highly beneficial by decreasing the impact of these stresses on other aspects of physical and psychological functioning in the elderly.

 

So, reduce mild aging cognitive decline with yoga.

 

“Meditation could be a promising intervention in contrasting the negative effects of aging. Indeed, it has been shown to enhance cognitive efficiency in several domains, such as attention and executive functions.” Marco Sperduti

Abstract

Background

Global population aging will result in increasing rates of cognitive decline and dementia. Thus, effective, low-cost, and low side-effect interventions for the treatment and prevention of cognitive decline are urgently needed. Our study is the first to investigate the effects of Kundalini yoga (KY) training on mild cognitive impairment (MCI).

Methods

Older participants (≥55 years of age) with MCI were randomized to either a 12-week KY intervention or memory enhancement training (MET; gold-standard, active control). Cognitive (i.e. memory and executive functioning) and mood (i.e. depression, apathy, and resilience) assessments were administered at baseline, 12 weeks and 24 weeks.

Results

At baseline, 81 participants had no significant baseline group differences in clinical or demographic characteristics. At 12 weeks and 24 weeks, both KY and MET groups showed significant improvement in memory; however, only KY showed significant improvement in executive functioning. Only the KY group showed significant improvement in depressive symptoms and resilience at week 12.

Conclusion

KY group showed short- and long-term improvements in executive functioning as compared to MET, and broader effects on depressed mood and resilience. This observation should be confirmed in future clinical trials of yoga intervention for treatment and prevention of cognitive decline

The Sense of Thought

The Sense of Thought

 

By John M. de Castro, Ph.D.

 

“Whatever you see you must be mindful of as it really is. Whatever you hear you must be aware of as it occurs. Whatever you smell you must be aware of as it really occurs. Whatever you taste you must be aware of as it really occurs. Whatever you touch you must be aware of as it really occurs. Whatever you think or think about you must be aware of as it really occurs.” – Buddha

 

The Buddha identified not five senses as traditional Western thought does, but six sense doors; vision, audition, olfaction, gustation, touch, and thought. The first time I read this I was taken aback; thought as a sense! I always considered thought as processing sensory information, not as a sensory experience itself. Indeed, Descartes stated “Cogito ergo Sum”, “I think therefore I am.” Thinking was the ultimate evidence of existence, not just a sense impression. But, for a moment reflecting on Descartes phrase “I think therefore I am,” I along with many others realized that the “I” refers to something other than the thinker! Something is sensing thought, even thinking about this.

 

It is not clear that thought is a separate sense. Rather it appears to take advantage of the brain systems used for processing information from the external world. That is why we can “hear” our internal voice, “see” imagined scenes, or “feel” remembered emotions. Also, chefs can “taste” and “smell” imagined dishes; mentally combining ingredients. There’s been a long standing controversy in Psychology regarding whether there is thought without some kind of internal sensory experience, called imageless thought. The issue is not resolved but what is clear is that the vast majority of thoughts involve mental images. Hence, it appears that thoughts are not something other than the traditional senses but take advantage of them. Perhaps we sense thought through sensing the influence of thought on the traditional senses. But, still something is sensing this and it isn’t the mind, the source of thought.

 

There is clearly, however, imageless experience or awareness. Awareness itself observes sensations and thoughts, including the images accompanying thoughts, but does not itself have images. It is pure contentless awareness. In advanced meditative states, this contentless awareness can be directly experienced. Even the novice practitioner can experience this by paying close attention to the gaps that exists between thoughts. But, the thoughts that the Buddha was talking about are the processes of the mind and these appear, for the most part, to involve images. These, in turn, appear to be experienced, not by the mind, but by something else that we label awareness.

 

We appear to be incapable of truly controlling thoughts. We believe that we are in control. But, meditation practice immediately reveals that we can’t. Try as we may to concentrate on one thing, control our thinking and focus our attention, the mind inevitably wanders off into other things; planning for the future, ruminating about the past, interpreting experience. We don’t seem to be able to control it. Rather than being in control of thoughts, thoughts appear to be in control of the mind, but do so in such a sneaky way that they provide the illusion that we’re in control.  As Eckhart Tolle said “Then the mind is using you. You are unconsciously identified with it, so you don’t even know that you are its slave. It’s almost as if you were possessed without knowing it, and so you take the possessing entity to be yourself.”

 

We may not be able to control our thoughts, but we can step back and witness them. Just like our awareness senses lights, sound, etc. it can sense thoughts. This is why the Buddha classified thought as a sense. If you watch these out of control thoughts it begins to dawn on you that there’s a distinct separation between your awareness and thoughts. The thoughts begin to appear almost alien, like they’re not really yours. As Eckhart Tolle said “So when you listen to a thought, you are aware not only of the thought but also of yourself as the witness of the thought. A new dimension of consciousness has come in. As you listen to the thought, you feel a conscious presence – your deeper self – behind or underneath the thought, as it were. The thought then loses its power over you and quickly subsides, because you are no longer energizing the mind through identification with it. This is the beginning of the end of involuntary and compulsive thinking.”

 

So, the fact that we can’t control thoughts adds to the case that thought is, as the Buddha said, a separate sense. Just like our classical five senses we can’t control their content, we can only experience them. This is an important insight. As Jon Kabat-Zinn said ““It is remarkable how liberating it feels to be able to see that your thoughts are just thoughts and that they are not ‘you’ or ‘reality.’ For instance, if you have the thought that you have to get a certain number of things done today and you don’t recognize it as a thought but act as if it’s the ‘the truth,’ then you have created a reality in that moment in which you really believe that those things must all be done today.” So, by recognizing thought as just another sense, the inner self, the awareness of sensing, is revealed.

 

This can be practiced, especially during meditation. Watching thoughts is what you do in open monitoring meditation. You simply watch them and don’t react to them; just letting them arise, and fall away. Here you can clearly observe thoughts passing through, completely out of control, but when you don’t dwell on them, they pass on through and disappear. But, nonetheless, whether they stay or not, they are experienced. It can’t be emphasized too much what an important insight this is. As Eckhart Tolle observed “The most decisive event in your life is when you discover you are not your thoughts or emotions. Instead, you can be present as the awareness behind the thoughts and emotions.” This is when you begin to realize the nature of your true self. This is when you begin to see things as they really are. This is when you begin to awaken.

 

“Since, if one leaves the senses of the eye, ear, nose, tongue, body & mind uncontrolled,
then evil detrimental states such as greed, lust & discontent invades & dominates the mind!
Therefore does one train control of the senses, guarding the senses, holding back the senses,
and one keeps in check these six wild-running senses…” – Buddha

Improve Brain Processing of Cognitive Conflict with Mindfulness

Improve Brain Processing of Cognitive Conflict with Mindfulness

 

By John M. de Castro, Ph.D.

 

“Mindfulness should no longer be considered a “nice-to-have” for executives. It’s a “must-have”:  a way to keep our brains healthy, to support self-regulation and effective decision-making capabilities, and to protect ourselves from toxic stress. When we take a seat, take a breath, and commit to being mindful, particularly when we gather with others who are doing the same, we have the potential to be changed.” – Christina Congleton

 

There is a tremendous amount of information present at any moment. It is a challenge to the nervous system to sort it out and pay attention to only the most significant information. This involves ignoring competing or conflicting stimuli and concentrating on only the most salient and pertinent stimuli. Mindfulness training can help. It involves a greater emphasis on attention to the immediate stimulus environment. So, it builds the capacity to focus on what is transpiring in the present moment. Mindful people generally have better attentional abilities and have fewer intrusive thoughts and less mind wandering. As a result, mindfulness has been shown to be associated with differences in thought processes.

 

One indirect method to monitor cognitive functions is through recording the electrical signals from the brain with the electroencephalogram (EEG). Electrical activity occurring at different frequencies is representative of the nature of the activity in the underlying brain tissue. The theta rhythm occurs in the frequency region of 4-7 cycles per second (Hz.). Recordings of Theta, particularly in the frontal regions of the brain have been shown to increase when attention is focused and mind wandering is minimized. Hence, the effects of mindfulness practice on the nervous may be seen in alterations to the Theta Rhythm in the frontal areas of the brain and the structures connected to them.

 

In today’s Research News article “Frontal Theta Dynamics during Response Conflict in Long-Term Mindfulness Meditators.” See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5461248/, Jo and colleagues recruited adult long-term (> 5 years) meditators (average 13.1 years) and non-meditators matched on gender and age. All participants had EEGs recorded while performing a flanker task, a measure of executive cognitive function, in which the participant has to respond to the direction of an arrow, when it is surrounded by distracting arrows that point either in the same (no-conflict) or opposite (conflict situation) directions.

 

They found that the meditators responded more accurately on the flanker task, making significantly fewer errors, particularly when the conflict situation was present. Hence, meditators demonstrated superior cognitive control and attentional ability. The Theta Rhythm power over the frontal areas was found to be higher for both groups during the conflict but not the no-conflict situation. The synchrony of the Theta Rhythm over the frontal areas and especially between the frontal areas and the motor cortex was greater for both groups during the conflict situation, but was significantly greater in the meditators. In addition, the greater the level of synchronization during the conflict situation the fewer the error made on the flanker task.

 

These are interesting results and suggest that long-term meditation practice enhances the individual’s cognitive and attentional ability particularly when conflicting stimuli are present. In addition, long-term meditation practice appears to alter the frontal areas of the nervous system enhancing their ability to resolve conflicts. So, meditation practice improves the brain and as a result the meditators cognitive attentional processing.

 

So, improve brain processing of cognitive conflict with mindfulness.

 

“Importantly, research has shown mindfulness to increase activity in brain areas associated with attention and emotion regulation. Mindfulness also facilitates neuroplasticity — the creation of new connections and neural pathways in the brain.” – Carolyn Gregoire

Abstract

Mindfulness meditators often show greater efficiency in resolving response conflicts than non-meditators. However, the neural mechanisms underlying the improved behavioral efficiency are unclear. Here, we investigated frontal theta dynamics—a neural mechanism involved in cognitive control processes—in long-term mindfulness meditators. The dynamics of EEG theta oscillations (4–8 Hz) recorded over the medial frontal cortex (MFC) were examined in terms of their power (MFC theta power) and their functional connectivity with other brain areas (the MFC-centered theta network). Using a flanker-type paradigm, EEG data were obtained from 22 long-term mindfulness meditators and compared to those from 23 matched controls without meditation experience. Meditators showed more efficient cognitive control after conflicts, evidenced by fewer error responses irrespective of response timing. Furthermore, meditators exhibited enhanced conflict modulations of the MFC-centered theta network shortly before the response, in particular for the functional connection between the MFC and the motor cortex. In contrast, MFC theta power was comparable between groups. These results suggest that the higher behavioral efficiency after conflicts in mindfulness meditators could be a function of increased engagement to control the motor system in association with the MFC-centered theta network.

Alter Brain Networks and Cognitive Ability with Tai Chi

Alter Brain Networks and Cognitive Ability with Tai Chi

 

By John M. de Castro, Ph.D.

 

” Another great benefit of Tai Chi is that it’s accessible to people of all ages and fitness abilities. It’s the focus on the subtle movements that exercise the brain and boost cognitive abilities.” – Karl Romain

 

Tai Chi is an ancient Chinese practice involving mindfulness and gentle movements. It is easy to learn, safe, and gentle. Tai Chi has been practiced for thousands of years with benefits for health and longevity. Tai Chi training is designed to enhance function and regulate the activities of the body through controlled breathing, mindful concentration, and gentle movements. Only recently though have the effects of this practice been scrutinized with empirical research. This research has found that it is effective for an array of physical and psychological issues. It appears to strengthen the immune system, reduce inflammation and increase the number of cancer killing cells in the bloodstream, improve cardiovascular health, reduce arthritis pain, improve balance and reduce falls. It also appears to improve attentional ability and relieve depression.

 

The nervous system is a dynamic entity, constantly changing and adapting to the environment. It will change size, activity, and connectivity in response to experience. These changes in the brain are called neuroplasticity. Over the last decade neuroscience has been studying the effects of contemplative practices on the brain and has identified neuroplastic changes in widespread areas. In other words, mindfulness practice appears to mold and change the brain, producing psychological, physical, and spiritual benefits. Hence, it would appear likely that Tai Chi practice may alter the brain networks underlying mindfulness.

 

In today’s Research News article “Mind-Body Practice Changes Fractional Amplitude of Low Frequency Fluctuations in Intrinsic Control Networks.” See summary below or view the full text of the study at: http://journal.frontiersin.org/article/10.3389/fpsyg.2017.01049/full?utm_source=F-AAE&utm_medium=EMLF&utm_campaign=MRK_325025_69_Psycho_20170711_arts_A

Wei and colleagues recruited healthy long-term practitioners of Tai Chi (average 14 years of practice) and age, gender, and education matched non-practitioners. All participants performed a flanker task, a measure of executive cognitive function, in which the participant had to respond to the direction of an arrow surrounded by distracting arrows. They found that the longer the practitioners had been practicing Tai Chi the faster they responded in the flanker, executive function, task. This suggests that Tai Chi practice enhances cognitive function.

 

The participants then underwent functional Magnetic Resonance Imaging (fMRI) brain scanning. The brain scans revealed that the Tai Chi practitioners had a significant reduction in amplitude of low frequency fluctuations in the brain areas called the Default Mode Network (DMN) which underlies mind wandering and self-referential thinking. There was also a significant reduction in amplitude of low frequency fluctuations in the brain areas called the frontoparietal network (FPN) and the dorsal prefrontal-angular network which are associated with cognitive control and executive function. These changes in the low frequency fluctuations suggest that Tai Chi practice produces changes in these networks increasing their functional connectivity.

 

These results are very interesting and suggest that Tai Chi practice can produce changes in the brain improving the connectivities within large-scale neural systems. At least in terms of the frontoparietal network (FPN) and the dorsal prefrontal-angular network these changes may underlie the ability of Tai Chi practice to improve cognitive control and executive function while the changes in the Default Mode Network (DMN) may underlie the ability of Tai Chi practice to reduce mind wandering and self-referential thinking. Hence, Tai Chi practice alters the nervious system and produces very beneficial effects

 

So, alter brain networks and cognitive ability with Tai Chi.

 

“Neuroplasticity may sound like an out of this world term to a normal Tai Chi practitioner but to those who pursue the path of the mind, Warriors of Intention, then this is the proven way of enabling our mind to permanently rewire the way we move.” – Mushin

Abstract

Cognitive control impairment is a typical symptom largely reported in populations with neurological disorders. Previous studies have provided evidence about the changes in cognitive control induced by mind-body training. However, the neural correlates underlying the effect of extensive mind-body practice on cognitive control remain largely unknown. Using resting-state functional magnetic resonance imaging, we characterized dynamic fluctuations in large-scale intrinsic connectivity networks associated with mind-body practice, and examined their differences between healthy controls and Tai Chi Chuan (TCC) practitioners. Compared with a control group, the TCC group revealed significantly decreased fractional Amplitude of Low Frequency Fluctuations (fALFF) in the bilateral frontoparietal network, default mode network and dorsal prefrontal-angular gyri network. Furthermore, we detected a significant association between mind-body practice experience and fALFF in the default mode network, as well as an association between cognitive control performance and fALFF of the frontoparietal network. This provides the first evidence of large-scale functional connectivity in brain networks associated with mind-body practice, shedding light on the neural network changes that accompany intensive mind-body training. It also highlights the functionally plastic role of the frontoparietal network in the context of the “immune system” of mental health recently developed in relation to flexible hub theory.
