LONDON - Doctors and chief executives could be 23% less likely than farm labourers to develop dementia, according to a new study.
Researchers measured how “cognitively stimulating” participants’ jobs were at an average age of 45 and followed them for about 17 years, by which time 1,143 had developed dementia.
They found that having a mentally stimulating job in the second half of a career may help to stave off dementia.
