Alzheimer's Disease: Imaging Key to Early Treatment

May 30, 2013

Increased accumulation of beta-amyloid in the brain is associated with gray matter atrophy and memory impairment in cognitively healthy older people, a subanalysis of the Australian Imaging, Biomarkers and Lifestyle (AIBL) Study of Aging has found.

The findings suggest PiB-PET imaging for amyloid deposits could be used to screen for cognitive impairment, Christopher C. Rowe, MD, of the University of Melbourne in Australia, and AIBL researchers reported in JAMA Neurology.
