Quizplus · Accepted Answer

Neurofibrillary tangles (abnormal clumps of protein called tau) and amyloid plaques (buildups of a protein called beta-amyloid) are both hallmark features of Alzheimer's disease. These accumulations disrupt normal brain function and communication, leading to cognitive impairment and other symptoms of the disease.
