Answer 1

Alzheimer's disease is the most common cause of dementia in the elderly. It is characterized by the presence of abnormal clumps called amyloid plaques, tangled brain fibers called neurofibrillary tangles, and an overall shrinking of brain volume.

Step-by-step explanation:

The most common etiology of dementia is Alzheimer's disease. Alzheimer's disease is the most common cause of dementia in the elderly. It is estimated that roughly one in every eight people age 65 or older has the disease.
