Question

Quizplus · Accepted Answer

Each senile plaque within the brains of patients with Alzheimer's disease contains beta-amyloid, a protein fragment that accumulates and clumps together in the brain, leading to the damage and death of nerve cells. NGF (nerve growth factor) is not typically associated with Alzheimer's disease, and neither is melanin (a pigment that gives color to the skin, hair, and eyes). Neurofibrillary tangles are also a hallmark characteristic of Alzheimer's disease, but they are not found within senile plaques.
