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.

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

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.

Better Measurement of Mindfulness, Anxiety, and Depression

By John M. de Castro, Ph.D.

 

“Thus, differing assessments may support implicitly distinct theoretical positions with respect to operationalizing mind- fulness. . . . researchers must be well informed and intentional in their selection of assessment tools because the breadth of currently available assessments provides researchers with a variety of measures, each with specific strengths and weaknesses. Not surprisingly, the various measures resulting from the diverse operational definitions of mindfulness have, at times, been found to be uncorrelated or only modestly associated, providing further evidence of confusion within the mindfulness literature.” – Adam Hanley

 

A prerequisite in science is that in order to study something you have to be able to measure it. With many concepts such as mindfulness, depression, and anxiety that reflect subjective states, there are currently no objective means to measure them. Measurement then falls to some kind of after the fact test or to a self-report. Traditionally, these variables have been measured with paper and pencil psychometric tests, such as the Cognitive Affective Mindfulness Scale-Revised, the Beck Depression Inventory, or the Profile of Mood States. They ask the participant to answer the question in regard to how they generally feel. These forms are filled out before and again after an intervention to assess the effect of the intervention on these subjective states.

 

With the advent of smart phones, a different kind of assessment method has emerged and is gaining greater popularity. It is sometimes called ecological momentary assessment (EMA). Individuals receive messages on their smart phones periodically asking them to answer questions about their state at the present moment. This can be done on multiple, somewhat randomly selected, occasions over the day or longer. It provides a measure that doesn’t require the participant to estimate how they feel in general, but rather uses an average of measures provided by the participant at various times.

 

In today’s Research News article “Ecological momentary assessment versus standard assessment instruments for measuring mindfulness, depressed mood, and anxiety among older adults”

https://www.facebook.com/ContemplativeStudiesCenter/photos/a.628903887133541.1073741828.627681673922429/1184314174925840/?type=3&theater

Moore and colleagues recruited elderly (over 65 years of age) participants with clinically significant anxiety distress. They compared the results for participants’ levels of mindfulness, depression, and anxiety measured either by traditional paper and pencil measures of how they were in general to those measured with an ecological momentary assessment (EMA) using smart phones. To obtain the EMA measures participants were sampled 3 times per day for ten days. The participants were randomly assigned to receive Mindfulness Based Stress Reduction (MBSR) program or a health education program. They were compared both before and after the interventions with both the traditional and EMA measurements.

 

Mindfulness Based Stress Reduction (MBSR) involves training in meditation, body scan, and yoga. It has been shown previously to increase mindfulness, and to decrease depression and anxiety levels in normal individuals and those with anxiety disorders, including the elderly. Moore and colleagues found in their study that on average both measures showed an increase in mindfulness and decreases in depression and anxiety, but, the effects were only statistically significant for ecological momentary assessment (EMA) and not for the traditional paper and pencil measures. These results suggested that EMA measurement in more sensitive and less unstable than traditional measures. To further document this, they calculated the number of participants that would be needed to show a statistically significant effects for the two measurement types and found that EMA measures required nearly half as many participants as the traditional measures. Hence, they found that EMA measure are substantially more sensitive and is capable of detecting differences with fewer participants.

 

These results indicate that ecological momentary assessment (EMA) is a better way to assess the states of research participants. Obtaining measures at a variety of points in time appears to produce more accurate results than asking the participant to estimate their overall states. This makes sense that actual measures are superior to participant estimates. The EMA technique is more expensive, takes more time and effort, and is more intrusive into the daily lives of the participants, but may be worth it for the improved accuracy and sensitivity.

Improve Physical and Cognitive Function with Tai Chi

“Because Tai Chi may impact cognitive function via a diverse and potentially synergistic set of mechanistic pathways, it is plausible that it may offer benefits superior to interventions that target only single pathways (e.g., aerobic training or stress reduction alone)” – Peter Wayne

 

The process of aging affects every aspect of the physical and cognitive domains. Every system in the body deteriorates including motor function with a decline in strength, flexibility, and balance. Impaired balance is a particular problem as it can lead to falls. In the U.S. one third of people over 65 fall each year and 2.5 million are treated in emergency rooms for injuries produced by falls. About 1% of falls result in deaths making it the leading cause of death due to injury among the elderly. It is obviously important to investigate methods to improve balance and decrease the number of fall in the elderly.

 

Perhaps more troubling than the physical decline is the mental deterioration that occurs with aging. This is called age related cognitive decline and includes decreases in memory, attention, and problem solving ability. 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.

 

It is, therefore, important to investigate methods to slow the mental decline during aging. Some promising methods are contemplative practices which have been shown to restrain age related declines. One particularly promising method is the ancient eastern practice of Tai Chi. It is particularly promising due to the fact that it is both a physical and a mental practice. Indeed, tai chi practice has been shown to slow cognitive decline in aging.

 

In today’s Research News article “Effects of Tai Chi and Western Exercise on Physical and Cognitive Functioning in Healthy Community-Dwelling Older Adults”

https://www.facebook.com/ContemplativeStudiesCenter/photos/a.628903887133541.1073741828.627681673922429/1177689028921688/?type=3&theater

http://www.ncbi.nlm.nih.gov/pmc/articles/PMC4699673/

Taylor-Piliae and colleagues randomly assigned sedentary adults over 60 years of age to either a tai chi practice, a physical exercise program, or attention (healthy aging) training. Training occurred twice a week in 90-minute classes and three times per week in home practices. They measured the physical and mental capabilities of the participants at 6 and 12 months of training. They found that both the tai chi and exercise groups improved in both flexibility and balance in comparison to the control condition. At 6 months the tai chi group was superior with balance while the exercise group was superior in flexibility, but at 12 months the two groups were equivalently superior to the control group in both flexibility and balance. In contrast, only the tai chi group demonstrated improved levels of cognitive function including memory and semantic fluency at both 6 and 12 months.

 

These results suggest that both tai chi and exercise are effective in slowing the physical decline with aging but tai chi has the added benefit of also slowing the cognitive decline. Since tai chi is safe, with no known adverse effects, and a gentle practice it is very appropriate for an aging population. Also, since it 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.

 

The results suggest that tai chi practice may be helpful in preventing falls as a result of improvement in balance and flexibility and slow the mental decline with aging. This indicates that tai chi practice should be recommended for elderly individuals to help maintain their physical and mental abilities. So, improve physical and cognitive function with tai chi.

Protect the Brain from Aging with Meditation

“Accumulating scientific evidence that meditation has brain-altering capabilities might ultimately allow for an effective translation from research to practice, not only in the framework of healthy aging but also pathological aging.” – Eileen Luders

 

The nervous system is a dynamic entity that changes in response to the experiences of the individuals and the demands they place upon it. This is a process called neuroplasticity. Contemplative practices place demands upon the brain and as a result produce neuroplastic changes increasing the size, activity, and connectivity of some structures while decreasing them in others (see http://contemplative-studies.org/wp/index.php/category/research-news/brain-systems/). In other words, contemplative practices appear to mold and change the brain.

 

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. But, there is evidence that it can be slowed. 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 (see http://contemplative-studies.org/wp/index.php/category/research-news/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 (see http://contemplative-studies.org/wp/index.php/category/research-news/brain-systems/). Indeed, the brains of practitioners of meditation and yoga have been found to degenerate less with aging than non-practitioners.

 

The structural changes that occur in the brain with aging involve a decrease in both grey matter, the neuron cell bodies, and white matter, the axons that interconnect structures. There have been numerous studies of the changes in grey matter that occur with aging and with contemplative practices, but there has been little research into changes in white matter. In today’s Research News article “Effects of Long-Term Mindfulness Meditation on Brain’s White Matter Microstructure and its Aging”

https://www.facebook.com/ContemplativeStudiesCenter/photos/a.628903887133541.1073741828.627681673922429/1174947885862469/?type=3&theater

http://www.ncbi.nlm.nih.gov/pmc/articles/PMC4712309/

Laneri and colleagues performed diffusion tensor imaging (DTI) on a group of adult long-term meditators and a comparable group who had never meditated. DTI measures the volume, connectivity, and integrity of white matter. They specifically investigated five areas of the white matter that are connected to areas that had previously been shown to be affected by meditation practice.

 

They found that four of the five areas investigated, Thalamus, Insula, Amygdala, and Hippocampus had significantly higher volume and activation in the meditators relative to the control participants. In addition, the meditators did not show the age related decline in volume and activation in all five structures that was apparent in the non-meditators. In other words, long-term meditation practice appears to spare the connections between key structures in the brain from age related declines. This supplements previous findings of increases in grey matter volume in these areas in meditators.

 

These results, together with previous studies of meditation effects on the brain suggest that meditation not only increases the size of neural areas but also the size and activation of their interconnections. Hence meditation appears to result in improved function in these areas. Importantly, these results suggest that meditation practice also helps to maintain the integrity of these structures during aging. These may be the neural changes underlying the protection that meditation produces from cognitive decline that occurs in aging.

 

Hence, meditation is an anti-aging practice. It may help to keep our nervous systems healthier for longer and as a result keep our mental abilities sharp for longer. So, protect the brain from aging with meditation.

Age Healthily: Improve Cellular Health with Mindfulness

psyjdc Leave a comment

 

“Simply responding to the physical symptoms of disease might make sense for treating an acute infection or fixing a broken leg, but to beat chronic age-related conditions such as diabetes, heart disease and dementia, we will need to embrace the fuzzy, subjective domain of the mind.” – Jo Marchant

 

Aging seems inevitable. But, different species age at different rates. Everyone knows for example that dogs’ life span is about 1/6th of the human life span. This suggests that there must be some biological mechanism that regulates aging. Recent genetic research is starting to uncover that mechanism. It has been found that the genes, coded on the DNA molecule, govern cellular processes in our bodies. One of the most fundamental of these processes is cell replication. Cells are constantly turning over. Dying cells or damaged are replaced by new cells. The cells turn over at different rates but most cells in the body are lost and replaced between every few days to every few months. Needless to say were constantly renewing ourselves.

 

As we age the tail of the DNA molecule called the telomere shortens. When it gets very short cells have a more and more difficult time reproducing and become more likely to produce defective cells. On a cellular basis this is what produces aging. As we get older the new cells produced are more and more defective. The shortening of the telomere occurs each time the cell is replaced. So, slowly as we age it gets shorter and shorter. This has been called a “mitotic clock.” This is normal. But, telomere shortening can also be produced by oxidative stress, which can be produced by psychological and physiological stress. This is mediated by stress hormones and the inflammatory response. So, chronic stress can accelerate the aging process. In other words, when we’re chronically stressed we get older faster.

 

Fortunately, there is a mechanism to protect the telomere. There is an enzyme in the body called telomerase that helps to prevent shortening of the telomere. It also promotes cell survival and enhances stress-resistance.  Research suggests that processes that increase telomerase activity tend to slow the aging process by protecting the telomere.  One activity that seems to increase telomerase activity and protect telomere length is mindfulness practice (see http://contemplative-studies.org/wp/index.php/2015/12/04/retreat-for-longevity/ and http://contemplative-studies.org/wp/index.php/2015/07/17/aging-healthily-yoga-and-cellular-aging/). Hence, engaging in mindfulness practices may protect the telomere and thereby slow the aging process.

 

In today’s Research News article “Telomerase activity and its association with psychological stress, mental disorders, lifestyle factors and interventions: A systematic review”

https://www.facebook.com/ContemplativeStudiesCenter/photos/a.628903887133541.1073741828.627681673922429/1168516629838928/?type=3&theater

Deng and colleagues review the published scientific literature on factors that influence telomerase activity. They report that chronic, long-term, psychological stress but not acute, short-term, stress reduced telomerase activity. They also report that Major Depressive Disorder is associated with reduced telomerase activity. Importantly, they find that diet, exercise, and mindfulness practices all increase telomerase activity. In particular, they found that “physical exercise, diet micronutrient supplementation, mindfulness meditation, Qigong practice or yoga mediation resulted in increase in telomerase activity.”

 

These are very exciting outcomes and suggest that mindfulness practices might contribute to longevity by reducing cellular aging. How might these very different practices increase telomerase activity? All of these mindfulness practices have been shown to reduce the psychological and physiological responses to stress (see http://contemplative-studies.org/wp/index.php/category/research-news/stress/). Since, chronic stress has been shown to reduce telomerase activity and in turn accelerate cellular aging, it would seem reasonable to conclude that practices that reduce stress responses would protect the individual from the deleterious effects of stress and increase telomerase activity. There may be other mechanisms involved, but this would seem to be the obvious one.

 

These findings suggest that mindfulness practices may improve longevity by protecting us from the damaging effects of chronic stress. By making us more mellow, we age slower.

 

So, age healthily: improve cellular health with mindfulness.

Age Healthily – Beat Increased Worry and Decreased Cognitive Ability with Mindfulness

psyjdc Leave a comment

 

“Aging has a wonderful beauty and we should have respect for that.” – Eartha Kitt

 

Worry and anxiety are associated with aging. These increases in the elderly can occur for very logical reasons. The elderly have to cope with increasing loss of friends and family, deteriorating health, as well as concerns regarding finances on fixed incomes. All of these are legitimate sources of worry. But, no matter how reasonable, the increased worry and anxiety add extra stress that can impact on the elderly’s already deteriorating physical and psychological health. So, clearly ameliorating the worry and anxiety could be highly beneficial to the well-being of the elderly.

 

Cognitive decline is also a problem with aging. There are reductions in memory ability, crystalized intelligence, reasoning and problem solving, attention, and processing speed that normally occur even with healthy aging. These changes can be slowed by reducing stress, improving health, and staying mentally active. One way to do this is with contemplative practices. Indeed, a variety of these practices have been shown to be helpful with the mental and physical changes associated with aging (see http://contemplative-studies.org/wp/index.php/category/research-news/aging/).

 

In today’s Research News article “Mindfulness-Based Stress Reduction for older adults with worry symptoms and co-occurring cognitive dysfunction”

https://www.facebook.com/ContemplativeStudiesCenter/photos/a.628903887133541.1073741828.627681673922429/1132072886816636/?type=3&theater

http://www.ncbi.nlm.nih.gov/pmc/articles/PMC4136987/

Lenze and colleagues tested the ability of a Mindfulness Based Stress Reduction (MBSR) program to reduce worry and anxiety and the mental decline in individuals over 65-years of age who had significant difficulties with worry and anxiety. They found that the MBSR program produced improvements in both cognitive abilities and worry and anxiety. In particular, the MBSR program improved memory ability, verbal fluency, speed of processing, and the ability to screen out interference during processing. They also found a large, clinically significant reduction in worry and anxiety severity and a large significant increase in mindfulness after the MBSR training in the elderly participants. Further they found that the participants continued to practice mindfulness techniques six and twelve months after the endo of formal training.

 

These are very promising results and suggest that mindfulness training might be an effective program to assist with successful, healthy aging. It has been shown that mindfulness training reduces the physical and psychological responses to stress (see http://contemplative-studies.org/wp/index.php/category/research-news/stress/). This by itself could be responsible to the positive effects of MBSR on the elderly. But mindfulness practice has also been shown to reduce worry (see http://contemplative-studies.org/wp/index.php/category/research-news/worry/) and anxiety (see http://contemplative-studies.org/wp/index.php/category/research-news/anxiety/) directly, which could also account for, the results with the elderly. This, however, may be a subcategory of mindfulness effects as mindfulness has been shown to improve emotion regulation in general (see http://contemplative-studies.org/wp/index.php/category/research-news/emotions/). Finally, mindfulness training has been shown to help protect the aging brain from deterioration (see http://contemplative-studies.org/wp/index.php/2015/07/17/age-healthily-protect-the-brain-with-yoga/) which might be the primary mechanism for the reduction in cognitive decline in the elderly. Regardless of the mechanism mindfulness training should be recommended to assist the elderly in aging healthily.

 

So, beat increased worry and decreased cognitive ability with mindfulness.

Retreat for Longevity

“People seek out retreats for themselves in the country, at the seaside, on the mountains…but nowhere can a person find a retreat more full of peace than one’s own soul.  Make use then of this retirement continually and regenerate thyself.” – Marcus Aurelius

 

The genes govern cellular processes in our bodies. One of the most fundamental of these processes is cell replication. Our bodies are constantly turning over cells. Dying cells or damaged are replaced by new cells. The cells turn over at different rates but most cells in the body are lost and replaced between every few days to every few months. Needless to say were constantly renewing ourselves.

 

As we age the tail of the DNA molecule called the telomere shortens. When it gets very short cells have a more and more difficult time reproducing and become more likely to produce defective cells. On a cellular basis this is what produces aging. There is an enzyme in the body called telomerase that helps to prevent shortening of the telomere. So, processes that increase telomerase activity tend to slow the aging process. Contemplative practice has been shown to increase telomerase activity thus helping to prevent cellular aging (see http://contemplative-studies.org/wp/index.php/2015/07/17/aging-healthily-yoga-and-cellular-aging/).

 

It is thought that this protection of telomeres could protect the body’s cells from aging and deterioration and be the basis for the increased longevity in contemplative practitioners. So, it is important to further investigate the effects of contemplative practices on telomeres and telomerase. In today’s Research News article “Telomere lengthening after three weeks of an intensive insight meditation retreat.”

https://www.facebook.com/ContemplativeStudiesCenter/photos/a.628903887133541.1073741828.627681673922429/1125997047424220/?type=3&theater

Conklin and colleagues measured telomere length in individuals participating in an intensive insight meditation retreat both before and after three weeks of retreat. They compared the telomere lengths to a group of individuals with a comparable amount of meditation experience but who were not participating in the retreat. They found that after three weeks of retreat the telomeres had significantly lengthened in the retreat group but not in the controls.

 

These findings are interesting and potentially important as they suggest that engagement in a meditation retreat can actually lead to improvement in cellular aging. It should be noted that this was not due to the fact that the participants were experienced meditators as the controls were comparably experienced in meditation. The only thing different was participation in the retreat.

 

This raises the question as to how participation in retreat might be producing a lengthening of telomeres. The authors raise the possibilities that the retreat facilitates “the participant’s cultivation of adaptive mental qualities, which mitigate psychological stress and counter stress-related telomere shortening.” Although this cannot be ruled out as a reasonable explanation, it should be noted that in the retreat the individual is removed from their normal life stresses and this may be the key to the retreat’s effectiveness. It is known that stress decreases telomere length and, if persistent, also reduces longevity. So, the break provided by the retreat may be responsible for lowering stress which in turn lengthens telomeres. It would have been interesting if the researchers had included a three-week vacation group that simply rested without intensive meditation to determine if it were the meditation retreat itself that was effective or simply the rest. Future research will be required to answer this question.

Regardless of the explanation it is clear that participating in a meditation retreat results in a lengthening of a marker of cellular aging, telomeres, and may thereby promote longevity.

 

So, retreat for longevity.

Regulate Emotions with Mindfulness

“If your emotional abilities aren’t in hand, if you don’t have self-awareness, if you are not able to manage your distressing emotions, if you can’t have empathy and have effective relationships, then no matter how smart you are, you are not going to get very far.” – Daniel Goleman

 

We are very emotional creatures. Without emotion, life is flat and uninteresting. Emotions provide the spice of life. We are constantly having or reacting to emotions. We often go to great lengths in an attempt to create or keep positive emotions and conversely to avoid, mitigate, or get rid of negative emotions. They are so important to us that they affect mostly everything that we do and say and can even be determinants of life or death. Anger, fear, and hate can lead to murderous consequences. Anxiety and depression can lead to suicide. At the same time love, joy, and happiness can make life worth living. Our emotions also affect us physically with positive emotions associated with health, well-being, and longevity and negative emotions associated with stress, disease, and shorter life spans.

 

The importance of emotions is only surpassed by our ignorance of them. Our rational side tries to downplay their significance and as a result research studies of emotions are fairly sparse and often ridiculed by politicians. So there is a great need for research on the nature of emotions, their effects, how they are regulated or not, and what factors affect them. One important factor is mindfulness. It has been shown to affect our ability to regulate emotions (see http://contemplative-studies.org/wp/index.php/category/research-news/emotions/). Research has demonstrated that people either spontaneously high in mindfulness or trained in mindfulness are better able to be completely in touch with their emotions and feel them completely, while being able to respond to them more appropriately and adaptively. In other words, mindful people are better able to experience yet control emotions.

 

In today’s Research News article “Mindfulness and emotion regulation in older and young adults.”

Prakash and colleagues delve into mindfulness, emotion regulation and dysregulation, and overall well-being in younger (mean 23 years of age) and older (mean 65 years of age) adults. They found that older adults were significantly higher in mindfulness and lower in emotional difficulties (dysregulation). They further found that people who were high in mindfulness were lower in emotional difficulties (dysregulation). This may have been due to the fact that people high in mindfulness were less likely to use suppression or thought avoidance to regulate emotions. As a result, mindful people tended to regulate emotions by confronting them rather than avoiding them. This was substantiated by the finding that high mindfulness was associated with higher emotional clarity. Finally, they found that age made a difference. The younger group had a much stronger tendency to use suppression and thought avoidance than the older group and the influence of these strategies on emotion dysregulation was stronger in the younger group.

 

These results help to clarify how mindfulness may help us avoid emotional difficulties and why older adults appear to have less emotional troubles. The key appears to be the type of strategy used to deal with emotions. Younger people tend to try to suppress the emotion or avoid thinking about it and as a result don’t experience fully, confront, or regulate emotions as well as older adults. But, younger people benefit greatly from mindfulness, reducing the maladaptive suppression and avoidance strategies, and thereby reducing the dysregulation of emotions. Older adults, on the other hand are more mindful and tend not to avoid emotions but to confront them with clarity and thereby are better able to deal with them.

 

So, regulate emotions with mindfulness.

 

“Mindfulness is the aware, balanced acceptance of the present experience. It isn’t more complicated than that. It is opening to or receiving the present moment, pleasant or unpleasant, just as it is, without either clinging to it or rejecting it.” – Sylvia Boorstein

Stay Mentally Fit as you Age with Tai Chi

“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

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.

Aging the Brain Healthily with Mindfulness

Aging the Brain Healthily with Mindfulness

 

“He who is of a calm and happy nature will hardly feel the pressure of age, but to him who is of an opposite disposition, youth and age are equally a burden.” – Plato (427-346 B.C.)

 

If we are lucky enough to survive long enough we’ll all have an opportunity to experience the aging process. It is a systematic progressive decline in every system in the body. It cannot be avoided. But, there is evidence that it can be slowed. 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 (see links below).

 

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 have found that contemplative practices of meditation and yoga restrain the loss of neural tissue with aging. The brains of practitioners degenerate less than non-practitioners.

 

The hippocampus is a large subcortical structure that has been shown to decrease in size and connectivity with aging. It also has been found that long-term meditators are somewhat protected from this deterioration. A part of the hippocampus known as the subiculum is of particular interest because it decreases in size with aging and is associated with memory and spatial ability, both of which decline with aging. In addition, the subiculum appears to be larger in long-term meditators. But it has yet to be seen if the age related deterioration of the subiculum is spared with meditation.

 

In today’s Research News article “Reduced age-related degeneration of the hippocampal subiculum in long-term meditators”

https://www.facebook.com/ContemplativeStudiesCenter/photos/a.628903887133541.1073741828.627681673922429/1114180745272517/?type=3&theater

Kurth and colleagues investigate this question by looking at the size of the subiculum in meditators and non-meditators ranging in age from 24 to 77 years. They found that the non-meditators showed the expected decrease in size of the subiculum with aging. But there was no significant decline in the subiculum size on the left side with aging with the meditators.

 

Hence, the findings of Kurth and colleagues suggest that meditation practice protects an important part of the brain from deteriorating with age. This is interesting and important and could reflect the mechanism by which meditation decreases the aging individual’s loss of memory and spatial ability.

 

Meditation is known to decrease the physiological and psychological responses to stress. In addition, stress including childhood trauma is known to produce a reduction in the size of the subiculum on the left side. It follows then the neuroprotective effects of meditation on the age related deterioration of the left subiculum may result from meditations known ability to reduce stress. Further research will be required to test this idea. Regardless, the results clearly demonstrate that meditation can result in less deterioration with aging of an important part of the brain.

 

So, meditate to reduce brain loss with aging.
