Alzheimer's risk may be increased by rapid brain development in youth; Y chromosomes may protect some men from dementia



Here’s a rather shocking article from “The Scientist” by Sukanya Charuchandra, “Aging[Related Diseases May Be a Natural Result of Human Evolution”, link
  
The theory is that fast-track developments in the brain to enable performance up through the reproductive years may make the brains more vulnerable to early deterioration after reproduction si impossible, especially with Alzheimer’s.  That sounds like plaque formation may result as an aftermath of earlier development.
  
There were some comparative studies with chimpanzees and gorillas.
  
Furthermore, however, Y chromosomes contain some genes that may help protect some men but not women from plaque formation. Previously, the higher incidence in Alzheimer’s in women has been attributed mainly to longer lifespans.
  
Back in 2010, I had been told by one assisted living center (when looking for mother) that 70% of the Alzheimer’s unit residents were women.
 
Jack Andraka retweeted this story Tuesday.
