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.

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.
