4. Brain Activity, Drugs Could Affect Alzheimer's Progression
The activity of connections among brain cells significantly affects levels of the toxic protein beta-amyloid (A�) that is a major cause of Alzheimer's disease (AD), researchers have found. A� is produced by the cleavage of amyloid precursor protein (APP) within brain cells. Findings suggest that the kind of mental activity people practice or drugs they might take for depression or anxiety could affect their AD risk or the disease progression.
