Scientists in the US who looked at 65 health elderly people, whose average age was 76, found those who did so tended to lower amounts of a destructive protein linked to Alzheimer’s disease, than those who were less mentally active.
The researchers at the University of California’s Berkeley campus found they had less beta-amyloid, which are thought to cause Alzheimer’s when they accumulate in sufficient quantities to fold into tangles plaques.
