Simple Lifestyle Changes May Improve Cognitive Function and Brain Efficiency

A UCLA research study published in the June issue of The American Journal of Geriatric Psychiatry found that people may be able to improve their cognitive function// and brain efficiency by making simple lifestyle changes such as incorporating memory exercises, healthy eating, physical fitness, and stress reduction into their daily lives.

“We’ve known for several years that diet and exercise can help people maintain their physical health and live longer, but maintaining mental health is just as important,” said lead investigator, Gary Small, M.D., professor of psychiatry and biobehavioral sciences at the Semel Institute for Neuroscience and Human Behavior at UCLA. “The UCLA study is the first to show the impact of memory exercises and stress reduction used together with a healthy diet and physical exercise to improve brain and cognitive function.”

Researchers found that after just 14 days following healthy lifestyle strategies, study participants’ brain metabolism decreased in working memory regions, suggesting an increased efficiency – so the brain didn’t have to work as hard to accomplish tasks.

For the two-week study, 17 subjects with normal baseline memory performance scores were randomly assigned to two groups: a control group did not make any behavior modifications while a test group incorporated healthy longevity strategies to improve physical and mental function.

Details of the healthy strategies employed in the study are also highlighted in Small’s new book, also published today, called “The Longevity Bible: 8 Essential Strategies for Keeping Your Mind Sharp and Your Body Young” (Hyperion, New York, 2006).

Participants on the healthy longevity plan incorporated the following into their daily routine:

?To improve physical fitness, participants took daily walks, which h
