NIH study reveals multiple mechanisms may play role in complex disorder

Researchers investigating a known gene risk factor for Alzheimer’s disease discovered it is associated with lower levels of beta amyloid — a brain protein involved in Alzheimer's — in cognitively healthy older people. The findings suggest that a mechanism other than one related to beta amyloid accumulation may influence disease risk associated with the gene.
