Question

Quizplus · Accepted Answer

The diseased brain of an Alzheimer's patient is characterized by both clumps of protein that inhibit neural transmission (called amyloid plaques) and neurofibrillary tangles. The protein clumps build up in the spaces between nerve cells and disrupt communications between nerve cells, while the neurofibrillary tangles are formed from twisted fibers of a protein called tau that normally help stabilize a neuron's internal support structure. Together, these two abnormalities are thought to contribute to the cognitive decline and memory loss seen in Alzheimer's disease.
