Over 90s and Dementia
(Reuters) 3 July 2008:
One of the archetypes of old age is the image of the mad old woman: not that we use that loaded description any more, using instead dementia. Recent studies show that, as with so many stereotypes, there is some truth in the matter.
Amongst those over 90 28 % of the men had dementia of one form or another and 45% of the women did.
Quite why this divide between the sexes is unknown: the researchers have two thoughts on the matter, but neither are proven. The first is that women live longer after a diagnosis of dementia, raising their relative numbers. The second is that so few men live beyond 90 that those who do have to be considered “hardy survivors” and simply less likely to get anything.
A question that clearly requires further research.
