Plaques and tangles in the brain characterize Alzheimer's disease.

Question

Quizplus · Accepted Answer

Plaques and tangles are two hallmark features of Alzheimer's disease. Plaques are clumps of beta-amyloid protein that build up between nerve cells in the brain, while tangles are twisted fibers of tau protein that accumulate inside the cells. These abnormal structures can interfere with communication between neurons and eventually cause cell death, leading to the memory loss, cognitive decline, and other symptoms associated with Alzheimer's disease.
