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.

Doctors must listen when patients talk of a failing memory

A team at the Aging and Memory Research Center, Semel Institute for Neuroscience and Human Behavior, University of California, Los Angeles, has found that a higher self awareness of memory difficulties may be associated with brain function decline over time, particularly in older adults with a genetic risk for Alzheimer's disease.

Higher self awareness of memory difficulties may be associated with brain function decline over time

Published in the April issue of the Archives of General Psychiatry, the study offers a greater understanding of how different types and varying degrees of memory complaints may relate to brain function decline, a finding that may lead to early treatment interventions for people who could develop Alzheimer's disease.
