AP PSYCHOLOGY

Detailed explanation-1: -It is formed from the breakdown of a larger protein, called amyloid precursor protein. One form, beta-amyloid 42, is thought to be especially toxic. In the Alzheimer’s brain, abnormal levels of this naturally occurring protein clump together to form plaques that collect between neurons and disrupt cell function.

Detailed explanation-2: -Alzheimer’s disease (AD) is the most frequent type of amyloidosis in humans and the commonest form of dementia.

Detailed explanation-3: -Amyloid plaques are the gradual buildup and accumulation of protein fragments between neurons; these form when Alzheimer’s disrupts the brain’s normal disposal process for the proteins, eventually impacting cognitive function.

Detailed explanation-4: -Amyloid plaques, which are found in the tissue between the nerve cells, are unusual clumps of a protein called beta amyloid along with degenerating bits of neurons and other cells. Neurofibrillary tangles are bundles of twisted filaments found within neurons.
