People who are free of dementia and have high levels of a protein that indicates the presence of inflammation have relatives who are more likely to avoid the disease as well, according to a new study published in the August 15, 2012, online issue of Neurology®, the medical journal of the American Academy of Neurology.
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.
