“For breath is life, and if you breathe well you will live long on earth.” – Sanskrit Proverb

Yoga practice is becoming increasingly popular in the west, for good reason. It has documented benefits for the individual’s psychological and physical health and well-being. It has also been shown to have cognitive benefits, improving memory. Yoga, however, consists of a number of components including, poses, breathing exercises, meditation, concentration, and philosophy/ethics. So, it is difficult to determine which facet or combination of facets of yoga are responsible for which benefit. Hence, it is important to begin to test each component in isolation to determine its effects.

Garg and colleagues test the effects of yogic breathing, specifically, left or right or alternating nostril breathing on memory ability. They randomly assigned adult female participants to three groups, right nostril breathing, left nostril breathing, or alternating nostril breathing. They practiced their respective breathing technique for 45 minutes per day for one week. Their verbal and spatial memory ability was then tested for 3 consecutive days before and after yogic nostril breathing.

They found that both verbal and spatial memory scores were improved by all three forms of breathing, but left nostril breathing produced superior verbal memory scores. There are no data to provide an explanation for the mechanism by which these breathing techniques improve memory. It is possible that they improve oxygenation of the hemispheres. Since the left hemisphere is generally involved in verbal ability, increasing oxygen flow to the left hemisphere may specifically improve verbal memory. It should be mentioned that there were no control conditions conducted. It is possible that the results were produced not by the breathing technique but by subject expectancy (placebo) effects or experimenter bias. It is also possible that nostril breathing is generally activating and this improves memory scores. Had a normal breathing control condition been conducted, this alternative hypothesis could have been addressed.

Nevertheless, improve memory with yoga nostril breathing techniques.

“This breathing exercise helps sharpen your concentration and mental clarity when your mind is dull. Alternate nostril breathing provides equal oxygen amounts to both sides of your brain. It is a great exercise to do before an important exam or interview.” – Ripa Ajmera

Abstract

Introduction: Yoga has beneficial effects on memory. In females, left hemisphere of the brain is responsible for verbal memory and right hemisphere is responsible for the spatial memory, while the opposite is true for males.

Aim: Aim of the present was to study the effect of unilateral right nostril breathing, left nostril breathing and alternate nostril breathing on verbal and spatial memory scores.

Materials and Methods: A total of 51 female subjects (age 18-25 years, mean±SD =21.71±3.11) were taken and divided into three groups (n=17). Each group was imparted one of the three different types of nostril breathing practices such as Right Nostril Breathing (RNB), Left Nostril Breathing (LNB) and Alternate Nostril Breathing (ANB) for 1 week for 45 minutes daily. Subjects were given the memory test, before and after 45 minutes of intervention for three consecutive days. Memory tests were performed by using Wechsler Adult Intelligent Scale.

Statistical Analysis: Results were analysed by ANOVA with SPSS version 17.0.

Results: Results showed that there was increase in recall of digit span-forward, digit-span backward, associate learning and spatial memory scores with RNB, LNB and ANB, which were statistically highly significant(p<0.005).

Conclusion: Inclusion of nostril breathing in exercise regimen may be helpful in improving recall of memory.

Improve Thought Executive Function with Mindfulness

May 6, 2016May 6, 2016 psyjdc 3 Comments

By John M. de Castro, Ph.D.

“mindfulness training on focusing on the present moment may develop control of attention, or executive function. This enhances capacity for sustained attention, attention switching, and inhibition of elaborative processing, thereby increasing our mastery over the content of our thoughts and actions. . . this amplifies our ability to self-regulate, allowing us to redirect our attention from rumination and depressogenic thoughts back to the experience of the present moment, thus decreasing negative affect and improving psychological health.” – Richard Chambers

Mindfulness practices such as meditation, yoga, and tai chi/qigong have been shown to have a myriad of positive benefits for the practitioner and they have been shown to alter a large variety of cognitive (thought) processes, such as attentional ability, memory, verbal fluency, critical thinking, learning, analytic thinking, mathematical ability, higher level (meta-cognitive) thinking, and cognitive reappraisal. There have not, however, been direct comparisons made between the practices to establish which may be superior for the improvement of which cognitive processes. In order to optimize the effectiveness of mindfulness practices to improve thinking it is important to determine the effective components of each practice.

In today’s Research News article “What Confucius practiced is good for your mind: Examining the effect of a contemplative practice in Confucian tradition on executive functions.” See:

https://www.facebook.com/ContemplativeStudiesCenter/photos/a.628903887133541.1073741828.627681673922429/1223639664326624/?type=3&theater

Teng and Lien compare the effectiveness of trainings for 4-weeks, twice a week for 90 minutes each, of mindful movements, or meditation, or a no treatment control. The mindful movement practice was termed Body-Mind Axial Awareness (BMAA) practice. It is very similar to tai chi except that the movements are not precisely choreographed and programmed. Chan meditation practice was used. It is very similar to Zen meditation and emphasizes breath following. They measured mindfulness, working memory ability, response inhibition (Stroop task), sustained attention and attentional switching ability.

They found that both the meditation and the mindful movement practices produced significant increases in mindfulness, in particular the observing and acting with awareness facets of mindfulness. They also found that the mindful movement practice produced a significant increase in working memory ability and sustained attention while the meditation training produced a significant increase in attentional switching ability. The groups did not differ in response inhibition ability. Hence, meditation practice appears to improve mindfulness and the ability to switch attention while the mindful movement practice improves mindfulness and working memory.

Increases in mindfulness, especially with the observing and acting with awareness facets, are routinely found with all mindfulness practices. So, these findings are not surprising and do not signal a difference between practices. The mindful movement practice requires continuous sustained attention in order to produce smooth movement sequences, so it makes sense that this practice would produce better sustained attention and therefore reduce mind wandering. This may, in turn, improve working memory ability as it improves sustained attention on the contents of memory, thereby reducing loss from working memory. It is possible that the training in focusing attention in the meditation practice that requires shifting attention back to the breath after mind wandering may be responsible for the improvements in attentional switching seen with meditation practice.

Although the equivalence of the mindful movement practice and the meditation practice was well maintained, one difference would be impossible to make equivalent and that is effects of the practice on the cardiovascular system. Mindful movement practice would be expected to raise heart rate, blood pressure, and metabolic rate while meditation would be expected to reduce them. In addition, the no treatment control is a weak control condition and a light exercise condition practiced over equivalent periods of time would be a much better comparison condition. So, for future research it might be useful to include a light exercise (e.g. walking) control condition.

Regardless improve thought executive function with mindfulness.

Abstract

The short-term training effects on various executive functions (EFs) by a movement-based contemplative practice (MBCP) are examined. Three aspects of EFs (working memory capacity, inhibition, switching) are assessed before and after a month-long 12-h training period using Body-Mind Axial Awareness (BMAA) principles that Confucius followers have practiced for more than 2000years. A mindfulness-based practice (Chan-meditation) and a waiting-list control group served as contrast groups. Our results showed that the BMAA group performed better on the task that measured working memory capacity than did the Chan-meditation and the waiting-list groups after training. In addition, the Chan-meditation groups outperformed the control group on attentional switching, a novel finding for this kind of practice. Our findings not only show a new effect of short-term MBCPs on EFs, but also indicate movement-based and mindfulness-based contemplative practices might benefit development of various aspects of EFs in different ways.

Healthy Aging – Improve the Brain and Memory with Tai Chi

Healthy Aging – Improve the Brain and Memory 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. First, it’s learning the precise movements of the ancient martial art form that will give your brain a boost. Then, it’s the continued focus linking the breath and the movements.” – Karl Romain

We all want to live longer. We celebrate the increasing longevity of the population. But, aging is a mixed blessing. The aging process involves a systematic progressive decline in every system in the body, the brain included. It cannot be avoided. Our mental abilities may also decline with age including impairments in memory, attention, and problem solving ability. These are called age related cognitive decline. This occurs to everyone as they age, but to varying degrees. Some deteriorate into a dementia, while others maintain high levels of cognitive capacity into very advanced ages. It is estimated that around 30% of the elderly show significant age related cognitive decline. But, remember that this also means that 70% of the elderly retain reasonable levels of cognitive ability. There is some hope, however, for those who are prone to deterioration as there is evidence that these cognitive declines can be slowed. For example, a healthy diet and a regular program of exercise can slow the physical 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 with aging.

Using modern neuroimaging techniques, scientists have been able to view the changes that occur in the nervous system with aging. In addition, they have been able to investigate various techniques that might slow the process of neurodegeneration that accompanies normal aging. They’ve found that mindfulness practices reduce the deterioration of the brain that occurs with aging restraining the loss of neural tissue. Indeed, the brains of practitioners of meditation and yoga have been found to degenerate less with aging than non-practitioners.

There are some indications that physical and mental exercise can reduce the rate of cognitive decline and lower the chances of dementia. Tai Chi and Baduanjin are ancient eastern practices involving slow mindful movements. They are both a gentle exercise and a contemplative practice that improves mindfulness. Mindfulness practices have been shown to improve cognitive processes while Tai Chi practice has been shown to slow age related cognitive decline. It would seem reasonable to hypothesize that Tai Chi and Baduanjin practices might decrease age related cognitive decline and the associated changes in the nervous system.

In today’s Research News article “Increased Hippocampus–Medial Prefrontal Cortex Resting-State Functional Connectivity and Memory Function after Tai Chi Chuan Practice in Elder Adults”

https://www.facebook.com/ContemplativeStudiesCenter/photos/a.628903887133541.1073741828.627681673922429/1212732788750645/?type=3&theater

Tao and colleagues investigated the effects of Tai Chi and Baduanjin practice on age related declines on memory and the neural systems involved in memory processes (Hippocampus and Medial Prefrontal Cortex). They randomly assigned 50-70 year-old participants to either Tai Chi practice, Baduanjin practice, or a no-practice control group. Both the Tai Chi and Baduanjin groups practiced one hour per day, 5-days per week, for 12 weeks.

They found that both Tai Chi and Baduanjin practice increased memory scores by about 25% while they were unchanged in the control group. They further found that both Tai Chi and Baduanjin practice increased the connectivity of the Hippocampus and Medial Prefrontal Cortex, indicating heightened communications between these memory related brain areas. In addition, the memory improvement was significantly positively associated with the increased connectivity, such that the greater the improvement in connectivity, the greater the improvement in memory. This is important in that it supports the conclusion that the changes in the brain are responsible for the improvements in memory.

It should be noted that the control group did not exercise. So, it cannot be determined if the improved memory and connectivity were due specifically to the mind-body aspects of Tai Chi and Baduanjin practices or due to the exercise provided by engaging in these gentle practices. It remains for future research to determine which aspect of the practices are responsible for the beneficial changes.

Regardless, the results are clear and exciting, Tai Chi and Baduanjin practice improves memory associated with improved connectivity between memory related brain areas in an aging population. In addition, Tai Chi and Baduanjin practices have the added benefit of being safe and gentle practices, with no known adverse effects. So, they are very appropriate for an aging population. Baduanjin practice does not involve the legs. So, it may be appropriate for aging groups who have difficulties with their hips, knees, ankles, fee, or legs. Finally, since they can be taught and practiced in groups and easily maintained at home, it is a very inexpensive intervention. This makes it almost ideal for aging individuals on fixed incomes.

So, improve the brain and memory with tai chi.

“Tai chi is often described as “meditation in motion,” but it might well be called “medication in motion.” There is growing evidence that this mind-body practice, which originated in China as a martial art, has value in treating or preventing many health problems. And you can get started even if you aren’t in top shape or the best of health.”– Harvard Women’s Health Watch

Frontiers in Aging Neuroscience, 8, 25. http://doi.org/10.3389/fnagi.2016.00025

Abstract

Previous studies provide evidence that aging is associated with the decline of memory function and alterations in the hippocampal (HPC) function, including functional connectivity to the medial prefrontal cortex (mPFC). In this study, we investigated if longitudinal (12-week) Tai Chi Chuan and Baduanjin practice can improve memory function and modulate HPC resting-state functional connectivity (rs-FC). Memory function measurements and resting-state functional magnetic resonance imaging (rs-fMRI) were applied at the beginning and the end of the experiment. The results showed that (1) the memory quotient (MQ) measured by the Wechsler Memory Scale-Chinese Revision significantly increased after Tai Chi Chuan and Baduanjin practice as compared with the control group, and no significant difference was observed in MQ between the Tai Chi Chuan and Baduanjin groups; (2) rs-FC between the bilateral hippocampus and mPFC significantly increased in the Tai Chi Chuan group compared to the control group (also in the Baduanjin group compared to the control group, albeit at a lower threshold), and no significant difference between the Tai Chi Chuan and Baduanjin groups was observed; (3) rs-FC increases between the bilateral hippocampus and mPFC were significantly associated with corresponding memory function improvement across all subjects. Similar results were observed using the left or right hippocampus as seeds. Our results suggest that both Tai Chi Chuan and Baduanjin may be effective exercises to prevent memory decline during aging.

Help Cancer Survivor Memory with Yoga

January 21, 2016 psyjdc 8 Comments

“Up to 75% of cancer patients experience some form of cancer-related cognitive impairment (CRCI) during cancer treatments (eg, chemotherapy, radiation, surgery, hormone therapy), and this impairment persists for months or up to 20 years in 20% to 35% of survivors.” – Janelsins, et al.

Cognitive impairments are a frequent side effect of cancer treatment. This has been dubbed “chemo brain.” Patients often refer to it as a mental cloudiness. The patients report problems including forgetting things, trouble concentrating, trouble remembering details like names and dates, trouble multi-tasking, like answering the phone while cooking, taking longer to finish things, disorganized and slower thinking, and trouble remembering common words. These cognitive impairments generally produce problems with work and even social relationships such that patients tend to isolate themselves. They can also produce treatment problems as the patients often forget to take their medications.

These problems result from the fact that chemotherapy, radiation therapy and many cancer drugs directly affect the nervous system. One of the potential intermediaries is sleep disruption as cancer treatments are known to produce sleep problems and lack of sleep is known to produce cognitive problems like those reported with “chemo brain.” At present there are no known treatments for these treatment induced cognitive impairments. Contemplative practices have been shown to affect memory (see http://contemplative-studies.org/wp/index.php/category/research-news/memory/), promote increased sleep quality (see http://contemplative-studies.org/wp/index.php/category/research-news/sleep/) and have positive effects on cancer treatment and recovery (see http://contemplative-studies.org/wp/index.php/category/research-news/cancer/). So, perhaps contemplative practices may be useful for the alleviation of “chemo brain” symptoms.

Yoga has been shown to improve sleep quality in recovered cancer patients. So, it would seem to be a likely contemplative practice candidate for the treatment of the cognitive effects of cancer treatment. In today’s Research News article “YOCAS©® Yoga Reduces Self-reported Memory Difficulty in Cancer Survivors in a Nationwide Randomized Clinical Trial: Investigating Relationships Between Memory and Sleep”

https://www.facebook.com/ContemplativeStudiesCenter/photos/a.628903887133541.1073741828.627681673922429/1152258194798105/?type=3&theater

Janelsins and colleagues conducted a randomized clinical trial of the effect of a yoga practice program on the sleep and cognitive symptoms of recovered cancer patients. They randomly assigned the patients, 2 to 24 months after completing surgery, chemotherapy, and/or radiation therapy, to either a yoga or a standard care group. The toga practice consisted of twice weekly 75-minute yoga sessions for four weeks. The study found that the yoga practice both reduced memory problems and sleep impairments. In addition, they showed that the sleep improvement was in part responsible for the yoga produced improvement in memory.

These results of this was a well conducted controlled trial are encouraging. Additionally, the yoga practice did not produce any adverse effects. So. the results suggest that yoga practice is a safe and effective treatment for the sleep and memory problems that accompany recovery from cancer. They further suggest that at least in part, the poor sleep quality in recovered cancer patients is responsible for some of the memory impairment and the sleep improvement produced by yoga may in part be responsible for some of the memory improvement seen in these patients. Since, yoga has many other physical and psychological beneficial effects (see http://contemplative-studies.org/wp/index.php/category/contemplative-practice/yoga-contemplative-practice/), it would seem to be an almost ideal addition to the usual care that recovered cancer patients receive.

So, help cancer survivor memory with yoga.

Mindfully Improve Memory

January 5, 2016 psyjdc 7 Comments

“Mindfulness registers experiences, but it does not compare them. It does not label them or categorize them. It just observes everything as if it was occurring for the first time. It is not analysis which is based on reflection and memory.” – Bhante Gunaratana

Humans have both an amazing capacity to remember and a tremendously limited capacity depending upon which phase of the memory process that is looked at. Our long-term store of information is virtually unlimited. We can recall in great detail events that occurred years ago or a few minutes ago. It not only includes events but things that were memorized by rote, music, places and their relationship to other places, faces, emotions, facts, definitions, etc. It’s really quite amazing. On the other hand, or very short-term memory is extremely limited. This is called our working memory and it can contain only about 5 to 9 pieces of information at a time. This fact of a limited working memory store shapes a great deal about how we think, summarize, and categorize our world.

Memory is not always accurate. We forget a great deal of information or have great difficulty retrieving it. We sometimes vividly recall things that really never happened to us, called false memories. Problems with memory are exacerbated by interference within memory where similar things tend to produce problems in our ability to recalling them. The problems with memory are well known in the legal system where the unreliability of eyewitness testimony is legendary. So, methods to improve memory and recall could be quite helpful, particularly to students who are required to recall information regularly.

Mindfulness has a mixed record in regards to its effects on memory. It has been shown to increase the likelihood of false memories and to impair memory for emotionally negative words but not positive words in adults (see http://contemplative-studies.org/wp/index.php/category/research-news/memory/). But mindfulness has also been shown to improve working memory capacity and Graduate Record Exam (GRE) scores among college students (see http://www.ncbi.nlm.nih.gov/pubmed/23538911). So, mindfulness appears to be able to improve some forms of memory while impairing others. It is thus important to sort out what kinds of memories are affected by mindfulness, in what way, and with whom.

In today’s Research News article “A Randomized Controlled Trial Examining the Effect of Mindfulness Meditation on Working Memory Capacity in Adolescents.”

https://www.facebook.com/ContemplativeStudiesCenter/photos/a.628903887133541.1073741828.627681673922429/1143318002358791/?type=3&theater

http://ac.els-cdn.com/S1054139X15003808/1-s2.0-S1054139X15003808-main.pdf?_tid=79ab478a-9055-11e5-80cd-00000aab0f27&acdnat=1448113429_d94f3f38ebf8666c5d47d94b9f652dbb

Quach and colleagues investigated the effect of contemplative practices on working memory in 12 to 17 year-olds. They compared students receiving 4-weeks of the meditation component of a Mindfulness Based Stress Reduction (MBSR) program to students receiving 4-weeks of Hatha yoga training and to untreated students on a wait list. They found that over the 4 weeks the students receiving meditation training significantly improved their working memory capacity while neither the yoga training nor the wait list groups did.

Hence the results indicated that meditation training improved short-term memory in adolescents. This adds to the prior results that mindfulness improved working memory in college students and suggests that meditation practice may be an effective method to improve an important component of students’ memories, working memory. This should, in turn, improve cognitive abilities such as problem solving, mathematics, etc. and improve school performance in general. But, future research will be required to confirm this speculation.

Meditation training improves attentional ability and present moment awareness and reduces mind wandering. These effects of meditation may well account for the improved working memory. By simply being able to concentrate better on the material and stay on task more will be entered into memory and less lost. Also, meditation training has also been shown to increase the size of brain areas involved in memory. This structural change in the nervous system might also underlie the improved working memory. Regardless of the mechanism it appears clear that meditation practice can lead to improved working memory in high school and college students.

So, mindfully improve memory.

Improve Mental and Physical Well-being with Yoga

December 23, 2015 psyjdc 1 Comment

“The breathing and meditative exercises aim at calming the mind and body and keeping distracting thoughts away while you focus on your body, posture or breath. Maybe these processes translate beyond yoga practice when you try to perform mental tasks or day-to-day activities.” – Neha Gothe

If we are lucky enough to navigate life’s dangers we are rewarded with the opportunity to experience aging! The aging process involves a progressive deterioration of the body including the brain. It actually begins in the late 20s and continues throughout the lifespan. It’s inevitable. We can’t stop it or reverse it. But, it is becoming more apparent that life-style changes can slow down and to some extent counteract the process and allow us to live longer and healthier lives. This is true for both physical and mental deterioration including degeneration and shrinkage of the nervous system. Aging healthily to a large extent involves strategies to slow down the deterioration.

Contemplative practices including yoga practice (See links below) have been shown to reduce the physical deterioration that occurs with aging (see http://contemplative-studies.org/wp/index.php/category/research-news/aging/). Yoga practice has many physical and mental benefits including protection of brain structures from degeneration with aging (see http://contemplative-studies.org/wp/index.php/2015/07/17/age-healthily-protect-the-brain-with-yoga/). These structural changes have been demonstrated by neuroimaging techniques with yoga practitioners. They document change in the size and connectivity of brain structures that result from yoga practice.

Yoga is a mind-body practice that involves both physical and mental exercises. This is accompanied by changes in the activity of virtually every component of the body including general physiology and the peripheral and central nervous systems. So, another potential method to investigate yoga’s effects on the nervous system is to measure the electrical signals emanating from the nervous system.

In today’s Research News article “Cognitive Behavior Evaluation Based on Physiological Parameters among Young Healthy Subjects with Yoga as Intervention”

https://www.facebook.com/ContemplativeStudiesCenter/photos/a.628903887133541.1073741828.627681673922429/1136173913073200/?type=3&theater

http://www.ncbi.nlm.nih.gov/pmc/articles/PMC4339827/

Nagendra and colleagues trained naive adults in yoga practice for a period of five months for 1.5 hours per day and compared physiological measure to a no-treatment control group. They found that yoga practice produced an increase in parasympathetic (vegetative) and decrease in sympathetic (activation) activity in the peripheral nervous system including a decrease in heart rate and heart rate variability. This indicates a calming and relaxing effect of yoga on the physiology.

Nagendra and colleagues also found significant differences in EEG activity of the central nervous system. The changes were complex and varied. But they are indicators that yoga practice produces alterations of brain activity in ways that are indicative of improved vigilance, alertness, attention, concentration ,memory, visual information processing, sense of wellbeing, responsiveness, emotion process, cognition, and executive function and reduced stress and strain. In other words the changes in the brain activity indicated vast improvements in mental processing produced by yoga practice.

It should be noted that these are indirect measures and the researchers did not directly measure the psychological variables. So, although suggestive they are not conclusive. They are, however, similar to findings of yoga effects in other research with direct measures (see http://contemplative-studies.org/wp/index.php/category/contemplative-practice/yoga-contemplative-practice/). But, even with this caution, the results suggest that yoga practice has widespread beneficial effects on the mental and physical well-being of the individual.

So, practice yoga and improve mental and physical well-being.

“True yoga is not about the shape of your body, but the shape of your life. Yoga is not to be performed; yoga is to be lived. Yoga doesn’t care about what you have been; yoga cares about the person you are becoming. Yoga is designed for a vast and profound purpose, and for it to be truly called yoga, its essence must be embodied.” — Aadil Palkhivala

Stay Mentally Fit as you Age with Tai Chi

November 24, 2015 psyjdc 1 Comment

“What helps with aging is serious cognition – thinking and understanding. You have to truly grasp that everybody ages. Everybody dies. There is no turning back the clock. So the question in life becomes: What are you going to do while you’re here?” – Goldie Hawn

Aging inevitably involves declining physical and mental ability. Starting in the late twenties the body, including the brain begins a process of slow deterioration. There is no known treatment to prevent this decline. There are, however, things that can be done to slow the progression. For example, a healthy diet and a regular program of exercise can slow the physical decline of the body with aging.

Our mental abilities may also decline with age including impairments in memory, attention, and problem solving ability. In sum these are called age related cognitive decline. This occurs to everyone as they age, but to varying degrees. Some deteriorate into a dementia, while others maintain high levels of cognitive capacity into very advanced ages. It is estimated that around 30% of the elderly show significant age related cognitive decline. But, remember that this also means that 70% of the elderly retain reasonable levels of cognitive ability.

There are some indications that physical and mental exercise can reduce the rate of cognitive decline and lower the chances of dementia. Tai Chi is an ancient eastern practice involving slow mindful movements. It is both a gentle exercise and a contemplative practice that improves mindfulness. Mindfulness practices have been shown to improve cognitive processes (see http://contemplative-studies.org/wp/index.php/category/research-news/cognition/) while Tai Chi or Qigong practice has been shown to be beneficial for healthy aging (see links below). It would seem reasonable to hypothesize that Tai Chi practice might decrease age related cognitive decline.

In today’s Research News article “The Impact of Tai Chi on Cognitive Performance in Older Adults: A Systematic Review and Meta-Analysis”

https://www.facebook.com/ContemplativeStudiesCenter/photos/a.628903887133541.1073741828.627681673922429/1121070961250162/?type=3&theater

http://www.ncbi.nlm.nih.gov/pmc/articles/PMC4055508/?report=classic

Wayne and colleagues review the published research on the application of Tai Chi to reduce age related cognitive decline in both elderly individuals who have already demonstrated cognitive decline and those who have not. They found that Tai Chi practice significantly reduced declines in executive function, including working memory, reasoning, task flexibility, problem solving and planning and execution. Tai Chi practice was also found to reduce declines in overall global cognitive function, including learning and memory, mathematical ability and semantic fluency. In addition, these improvements related to Tai Chi practice occurred in both individuals who had already experienced cognitive decline and those who had not. Importantly, these benefits were provided without any significant adverse side effects.

Wayne and colleagues hypothesize that Tai Chi may be having its positive effects on cognition through a number of mechanisms. These include the exercise provided by the practice with associated improvements in agility and mobility, the learning of a new skill, the required attentional focus, shifting, and multi-tasking, the mindfulness practice, and the social context of Tai Chi. Any and all of these process involved in Tai Chi practice may be responsible for its cognitive benefits.

Regardless of the mechanism, it appears that Tai Chi is a safe and effective practice that reduces the rate of age related cognitive decline whether or not decline was already present. These are exciting findings as Tai Chi has been shown to have many physical benefits for the elderly (see links below). The fact that it also has cognitive benefits makes it an even better choice for practice by the elderly.

So practice Tai Chi and stay mentally fit as you age.

“Tai chi… might well be called “medication in motion.” There is growing evidence that this mind-body practice…has value in treating or preventing many health problems.” – Harvard Medical School’s Harvard Health Publication, May, 2009

Mindfulness Effects on Cognitive Function

Meditation is not always a Good Thing

“When I was younger, I could remember anything, whether it had happened or not.” –Mark Twain

Sometimes we clearly remember information that was not in fact true. Have you ever been absolutely sure that you left your keys on a kitchen counter, only to find them in the bedroom? Have you ever been certain that you went to a particular movie with your spouse only to find out it was with a friend? These are called false-memories. They are not fabricated out of thin air. Rather, they often occur due to confusion where an actual memory is misattributed to an incorrect context. False-memories are frequently due to a failure to distinguish the source of the memory.

Most of the time these are innocuous and we can chuckle about our memory problems. But sometimes they become very serious. This is the case with eyewitness testimony. Research has demonstrated repeatedly how false memories can creep in to alter these memories and influence the outcome of a trial. They can also be a major problem in memories of childhood trauma and abuse. It’s now known that children must be very carefully interviewed to make sure that a false memory does not emerge. The consequences of false memories in these cases can be dire.

In order to counter false memories we have to be careful when a memory arises to judge it rigorously to be certain of the source of the memory. Mindfulness training is devoted to accepting things just as they are and not judging them. This would seem to be counter to the need for screening false memories. It is known that meditation can improve memory and in some cases can impair memory. Mindfulness training can make it easier to forget negative things (see http://contemplative-studies.org/wp/index.php/2015/09/08/forget-the-bad-stuff-with-mindfulness/). So, there is reason to believe that mindfulness training might improve memory or it might make it harder to identify false memories.

In today’s Research News article “Increased False-Memory Susceptibility after Mindfulness Meditation”

Wilson and colleagues attempted to answer whether mindfulness training might improve or impair the detection of false memories. The test was simple. Students viewed a list of words one at a time such as garbage, waste, can, refuse, sewage, bag, junk, rubbish, sweep, scraps, pile, dump, landfill, debris, and litter. Such a list can often induce a false memory of the word trash which is actually not on the list. After mindfulness training the students were nearly twice as likely to report seeing the word trash.

These results suggest that mindfulness training can at time actually be harmful. Inducing judgment-free awareness and acceptance can produce difficulty identifying the source of the memory. Mindfulness training might improve memory by reducing the filters that tend to screen it out. Hence, the same mindfulness training that produces many benefits can also have the unintended negative consequence of increasing false-memory susceptibility.

So, mindfulness provides great benefits but can also produce some problems. It is important to be careful with memory recall after mindfulness training to avoid false memories.

“It is singular how soon we lose the impression of what ceases to be constantly before us. A year impairs, a luster obliterates. There is little distinct left without an effort of memory, then indeed the lights are rekindled for a moment — but who can be sure that the Imagination is not the torch-bearer?” ~Lord Byron

Forget the Bad Stuff with Mindfulness

“Suffering is not holding you. You are holding suffering. When you become good at the art of letting sufferings go, then you’ll come to realize how unnecessary it was for you to drag those burdens around with you.” – Osho

There are a number of ideas as to why mindfulness is so beneficial, but one idea that has not been previously tested is that mindfulness may alter memory. In today’s Research News article “The Effect of a Brief Mindfulness Intervention on Memory for Positively and Negatively Valenced Stimuli”

https://www.facebook.com/ContemplativeStudiesCenter/photos/a.628903887133541.1073741828.627681673922429/1084477301576195/?type=1&theater

Alberts and Thewissen investigate the effect of the induction of mindfulness on the memory for words that are rated as feeling emotionally either positive or negative. They found that mindfulness did not improve or impair memory overall. But, it altered what tended to be remembered. The mindfulness group had significantly poorer memory for those words that were emotionally negative.

This suggests that mindfulness impairs negative memories. It makes us better at forgetting and letting go of troubling memories. This may be one of the ways that mindfulness improves mood, by focusing on the good things in life and forgetting the bad things. Negative emotions such as anxiety, depression, anger, worry etc. all rely on a memory process. It is troubling memories of real or imagined past events that create these emotions. Being able to better forget them should reduce these negative emotions. In this way mindfulness may have great psychological benefit.

Mindfulness training emphasizes non-judgmental awareness. We are instructed when memories intrude on the present moment awareness to not judge them as either good or bad, just to see them as memories, nothing more, nothing less, and let them pass away. Mindfulness, by making us less judgmental about past memories they may be neutralized and become less troubling. This could help to control negative emotions. So, mindfulness may be improving our psychological makeup by helping us focus of the positive memories and let go of the negative memories.

So, be mindful and forget the bad stuff.

“Let go. Why do you cling to pain? There is nothing you can do about the wrongs of yesterday. It is not yours to judge. Why hold on to the very thing which keeps you from hope and love?” – Leo Buscaglia
