Senile Plaques
Accumulations of beta-amyloid protein fragments in the brain, considered a hallmark of Alzheimer's disease.
Neurofibrillary Tangles
Twisted fibers found within brain cells that are one of the hallmark features of Alzheimer's disease, contributing to the degeneration of brain tissues.
