WebPlaques and Tangles. Amyloid Plaques and Tau Tangles are believed to be the two molecules responsible for the brain damage associated with Alzheimer's disease. Both Plaques and Tangles are present in the brains of individuals without Alzheimer's; however, they are found at much higher levels in the brains of Alzheimer's patients. WebConclusion: The impact of NAC on cerebral cortical plaque load increase may result from the vascular pathology of SHRSP that accompanies BBB breakdown, leading to the failure of amyloid clearance mechanisms.
