A sharper mind: how tai chi may boost cognitive function
Until about two decades ago, scientists believed the brain produced new cells only early in life. Research now shows that the brain can change across the lifespan by growing new cells, forming new connections, and even increasing in size. These changes can strengthen cognitive function, and several forms of exercise—including tai chi—may help support them.
A meta-analysis of 20 studies found that tai chi may improve executive function—the ability to multitask, manage time, and make decisions—in people without cognitive decline. Among those with mild cognitive impairment, tai chi slowed progression to dementia more than other exercises and improved cognition about as well as other exercise programs or cognitive training.
In one study, nearly 400 adults with some cognitive impairment practiced either tai chi or a stretching and toning program three times a week. After one year, the tai chi group improved more, and only 2% progressed to dementia, compared with 11% in the traditional exercise group.
Another study found tai chi more effective than walking. After 40 weeks of tai chi, walking, social interaction, or no intervention, MRI scans showed the greatest increase in brain volume among participants in the tai chi group. They also scored higher on cognitive tests.
