The most current research

The analyze, printed March 8 on the net in the journal Neurology, associated 581 individuals getting component in the Hurry Memory and Growing older Task, a continuing review of older older people initiated in 1997. Members ended up dementia-no cost when enrolled into the research.

Members in the present assessment, normal age of 84 at the start out of the research, had agreed to donate their brains at loss of life to advance dementia investigate.
