Question

Quizplus · Accepted Answer

Alzheimer's disease is characterized by the presence of abnormal microscopic structures in the brain, such as amyloid plaques and neurofibrillary tangles. Older individuals with Down syndrome also have an increased risk of developing Alzheimer's disease, likely due to the presence of an extra copy of chromosome 21, which includes the gene for amyloid precursor protein. Tay-Sachs disease, Korsakoff's syndrome, Parkinson's disease, and status epilepticus do not typically involve the development of these abnormal structures in the brain.
