Question

Quizplus · Accepted Answer

The abnormal protein found in the brains of people with Alzheimer's disease is called amyloid. This protein clumps together and forms plaques which can damage nerve cells in the brain, leading to the symptoms of Alzheimer's disease. Sonic hedgehog and nerve growth factor are both proteins involved in the development and maintenance of the nervous system, but they are not directly associated with Alzheimer's disease. Phenylalanine is an amino acid and is not directly related to Alzheimer's disease either.
