Dementia, fitness link

CERTAIN types of exercise do not prevent decline among dementia patients and may even worsen cognitive impairment, a new study suggests.

Moderate to high intensity aerobic and strength training did not slow cognitive impairment, researchers found. This sort of exercise may even worsen the condition, the authors suggested.

The study, published in the British Medical Journal, found that among patients with mild to moderate dementia an exercise program did not halt progress of their condition but did make them physically fitter.
