The National Academies issued the following news release:
Gradual and variable change in mental functions that occurs naturally as people age, not as part of a neurological disease such as Alzheimer's disease, is one of the most challenging health issues encountered by older adults, says a new report (http://www.nap.edu/catalog/21693/cognitive-aging-progress-in-understanding-and-opportunities-for-action) from the Institute of Medicine. The aging process affects the brain just like any other part of the body. Known as "cognitive aging," the type and rate of change can vary widely among individuals. Some will experience very few, if any, effects, while others may experience changes in their memory, speed of processing information, problem solving, learning, and decision-making abilities. The committee that carried out the study and wrote the report proposed three top actions individuals can take to help maintain optimal cognitive function with age.
"Changes in mental functions and capabilities are a part of aging and occur with everyone," said committee chair Dan G. Blazer, the J.P. Gibbons Professor of Psychiatry Emeritus at Duke University Medical Center in Durham, N.C. "The extent and nature of these changes vary widely and are gradual, and aging can have both positive and negative effects on cognition. Wisdom and knowledge can increase with age, while memory and attention can decline."
Aging can affect cognitive abilities needed to perform daily tasks, such as driving, following recipes, adhering to medication schedules, and paying bills, the committee said. As they get older, individuals of all ages should take the following three steps to help promote cognitive health:
* Be physically active.
* Reduce and manage cardiovascular disease risk factors, including high blood pressure, diabetes, and smoking.
* Regularly discuss and review health conditions and medications that might influence cognitive health with a health care professional. A number of medications can have a negative effect -- temporary or long term --on cognitive function when used alone or in combination with other medication.
Other actions that may promote cognitive health:
* Be socially and intellectually active, and continually seek opportunities to learn.
* Get adequate sleep and seek professional treatment for sleep disorders, if needed.
* Take steps to avoid...
