Improve Memory and Frontal Lobe Function in Older Adults with Mind-Body Practices

The nervous system is a dynamic entity, constantly changing and adapting to the environment. It will change size, activity, and connectivity in response to experience. These changes in the brain are called neuroplasticity.  Over the last decade neuroscience has been studying the effects of contemplative practices on the brain and has identified neuroplastic changes in widespread area. and have found that meditation practice appears to mold and change the brain, producing psychological, physical, and spiritual benefits.


The aging process involves a systematic progressive decline in every system in the body, the brain included. Starting in the 20s there is a progressive decrease in the volume and activity of the brain as the years go by. Researchers 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, yoga and Tai Chi have all been found to degenerate less with aging than non-practitioners. A practice, similar to Tai Chi, Baduanjin is a mind-body training consisted of 8 movements for limbs, body-trunk, and eye movements. But it has not been evaluated for application to aging individuals.

Because Tai Chi and Baduanjin are not strenuous, involving slow gentle movements, and are safe, having no appreciable side effects, they are appropriate for all ages including the elderly and for individuals with illnesses that limit their activities or range of motion.


In today’s Research News article “Tai Chi Chuan and Baduanjin Mind-Body Training Changes Resting-State Low-Frequency Fluctuations in the Frontal Lobe of Older Adults: A Resting-State fMRI Study.” (See summary below or view the full text of the study at: ), Tao and colleagues recruited older sedentary adults (50 to 70 years of age) and randomly assigned them to either a no-treatment control who were provided health information or to practice either Tai Chi or Baduanjin mind-body training for 12 weeks, one hour per day, five days per week. Participants were measured before and after training for memory and cognitive functions. They also underwent functional-Magnetic Resonance Imaging (f-MRI).


They found that the Tai Chi and Baduanjin groups did not differ, but, in comparison to baseline and the education control group they had significant (18%-24%) increases in memory performance after training. The brain scans demonstrated that, in comparison to the education control group the Baduanjin group had significant increases in activity in the low frequency range in the Medial Prefrontal Cortex while the Tai Chi group had significant increases in activity in the low frequency range in the Dorsal Lateral Prefrontal Cortex. Importantly, they found that the greater the increase in activity in the Prefrontal Areas the greater the improvement in memory.


Hence, the results showed that both mind-body practices of Tai Chi and Baduanjin improved memory in older adults in association with increases in Prefrontal Lobe activity. The Prefrontal cortex has been associated previously with memory, attention, and high-level thinking (executive function). The present results suggest that the mind-body practices of Tai Chi and Baduanjin act to improve memory in older adults by producing neuroplastic changes that increase activity in the brain’s Prefrontal Areas. Interestingly, the results also show that the two mind-body practices may act on different mechanisms in the brain; with Tai Chi acting on the medial areas of the Prefrontal Cortex while Baduanjin acting on the Dorsal Lateral areas.


Memory deteriorates with aging and this can progress to severe memory impairments and dementia. The results of this study suggest that engagement in the mind-body practices of Tai Chi and Baduanjin may be able to slow or prevent that decline by strengthening brain processing in the Prefrontal Cortex. Since both Tai Chi and Baduanjin are simple and safe exercises that can be easily learned and practiced at home alone or in groups, they are economical and scalable practices to improve memory during aging. As such, they should be recommended for older adults.


So, improve memory and frontal lobe function in older adults with mind-body practices.


“Because Tai Chi can be done indoors or out, and as a group activity or by yourself, it suits both people who like to work out alone at home and those who prefer to get their exercise in a social setting.” – Mark Huntsman

Study Summary


Tao, J., Chen, X., Liu, J., Egorova, N., Xue, X., Liu, W., … Kong, J. (2017). Tai Chi Chuan and Baduanjin Mind-Body Training Changes Resting-State Low-Frequency Fluctuations in the Frontal Lobe of Older Adults: A Resting-State fMRI Study. Frontiers in Human Neuroscience, 11, 514.



Age-related cognitive decline is a significant public health concern. Recently, non-pharmacological methods, such as physical activity and mental training practices, have emerged as promising low-cost methods to slow the progression of age-related memory decline. In this study, we investigated if Tai Chi Chuan (TCC) and Baduanjin modulated the fractional amplitude of low-frequency fluctuations (fALFF) in different frequency bands (low-frequency: 0.01–0.08 Hz; slow-5: 0.01–0.027 Hz; slow-4: 0.027–0.073 Hz) and improved memory function. Older adults were recruited for the randomized study. Participants in the TCC and Baduanjin groups received 12 weeks of training (1 h/day for 5 days/week). Participants in the control group received basic health education. Each subject participated in memory tests and fMRI scans at the beginning and end of the experiment. We found that compared to the control group: (1) TCC and Baduanjin groups demonstrated significant improvements in memory function; (2) TCC increased fALFF in the dorsolateral prefrontal cortex (DLPFC) in the slow-5 and low-frequency bands; and (3) Baduanjin increased fALFF in the medial PFC in the slow-5 and low-frequency bands. This increase was positively associated with memory function improvement in the slow-5 and low-frequency bands across the TCC and Baduanjin groups. Our results suggest that TCC and Baduanjin may work through different brain mechanisms to prevent memory decline due to aging.
