From Alzheimer's Daily News:
(Source: Opposing Views) - 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.
"The prevailing hypothesis has implicated factors increasing beta amyloid in the brain as an integral element of Alzheimer's disease pathology," said Richard J. Hodes, " This study indicates the importance of exploring and understanding other distinct mechanisms that may be at work in this disease."
