New research suggests healthy lifestyles can help stave off dementia, perhaps by building a resilient ‘cognitive reserve’ in the aging brain. The study was based on the brain autopsies on 586 people who lived to an average age of almost 91. Researchers compared each person’s lifestyle and end-of-life mental skills to their neurological signs of… read on > read on >
