Memory Problem Prevention

Cigarette smokers and people with high levels of education appear to have some protection against ARCD. The reason for each of these associations remains unknown. However, as cigarette smoking generally is not associated with other health benefits and results in serious health risks, doctors recommend abstinence from smoking, even by people at risk of ARCD.

A large, preliminary study in 1998 found associations between hypertension and deterioration in mental function. Research is needed to determine if lowering blood pressure is effective for preventing ARCD.

A randomized, controlled trial determined that group exercise has beneficial effects on physiological and cognitive functioning, and well-being in older people. At the end of the trial, the exercisers showed significant improvements in reaction time, memory span, and measures of well-being when compared with controls. Going for walks may be enough to modify the usual age-related decline in reaction time. Faster reaction times were associated with walking exercise in a British study. The results of these two studies suggest a possible role for exercise in preventing ARCD. However, controlled trials in people with ARCD are needed to confirm these observations.

Psychological counseling and training to improve memory have produced improvements in cognitive function in persons with ARCD.
