Alzheimer's: Amyloid Eclipses Genetic Risk

October 16, 2012

Memory may fade faster in brains clogged by amyloid plaques than those at genetic risk of Alzheimer's disease, researchers found.

High levels of beta-amyloid protein in the brain were associated with greater decline in working memory and verbal and visual episodic memory over 18 months among cognitively normal individuals, Yen Ying Lim, MPsych, of the University of Melbourne in Victoria, Australia, and colleagues reported in the Oct. 16 issue of Neurology.
