Dr Eric Larson, the centre’s director, said: ‘Everyone had expected the earliest signs of dementia would be subtle cognitive changes. We were surprised to find that physical changes can precede declines in thinking.’ He added that what is considered a brain disease may be intimately connected to physical fitness. The study, which was reported in the Archives of Internal Medicine journal yesterday, looked at 2,288 people who were aged 65 and older, none of whom showed any signs of dementia. The researchers contacted them every […]
