Molecular switches age-related memory decline? Genetic variant protect against brain aging
Date:5/6/2014

carry the T allele, as either CT or TT, performed better on the memory task and showed more active engagement in the hippocampus, a vital brain region for memory, with increasing age.

"Our results show a dynamic relationship between this gene and increasing age on hippocampal function and episodic memory with the non-T allele group showing a significant decline across the adult life span," said Mattay. "A similar relationship was not observed in the T-allele carrying group suggesting that this variant of the gene may confer a protective effect."

Dr. John Krystal, Editor of Biological Psychiatry, commented, "The risk mechanisms for age-related memory impairment that we identify today may become the targets for the prevention and treatment of this problem in the future."
