those who held negative stereotypes of seniors at the start of the study were more likely to develop the hallmarks of Alzheimer’s later: a decrease in the volume of the brain’s hippocampus—a key memory center—and an increase in amyloid plaques and neurofibrillary tangles.All subjects gave their optimistic/pessimistic views 20 years before the diagnosis was confirmed in some of them.
Among the 158 subjects who had MRIs, those holding more-negative views showed three times more hippocampal decline than those with less-negative views. Among the 74 subjects who had autopsies, the negatives had a “significantly greater accumulation” of plaques and tangles."A cheerful heart is good medicine." -- Proverbs 17:22
