Question

Quizplus · Accepted Answer

Alzheimer's disease is characterized by the death of neurons and the accumulation of abnormal proteins in the brain, including tangles of neuronal fibers (tau protein) and plaques of beta-amyloid protein. These changes cause destruction and atrophy of brain tissue, which leads to the cognitive and functional decline observed in Alzheimer's patients.
