Exercise now to cut dementia risk

Exercising for half an hour at least twice a week during midlife can significantly cut a person's risk of dementia later, say researchers.

People in their late 40s and early 50s who do this could reduce their risk of dementia by about 50%, according to a study reported in Lancet Neurology.

Those who are genetically prone to Alzheimer's disease could see a reduction of about 60%, it adds.

The Swedish team said the findings had large disease prevention implications.
