Possible missing link in Alzheimer’s Pathology Identified

Alzheimer’s disease has long been characterized by the buildup of two distinct proteins in the brain: first, beta-amyloid, which accumulates in clumps, or plaques, and tau, which forms toxic tangles that lead to cell death. Until now, exactly how beta-amyloid leads to the devastation of tau has not been clear. A new study at the University of Alabama at Birmingham describes that missing mechanism. Read more here.


Losing Even Just One Night of Sleep May Trigger Alzheimer’s Biomarker

According to a new small study, losing just one night of sleep may increase a biomarker associated with Alzheimer’s disease. The study, published in Neurology, found that tau protein — considered to be one of the main marks of Alzheimer’s — became more prevalent in the brains of young men who lost one night of sleep.
