Quizplus · Accepted Answer

Korsakoff's syndrome is a disorder caused by a deficiency in thiamine (vitamin B1), often due to long-term alcohol abuse. Damage to the dorsomedial thalamus and mamillary bodies is a common neuropathological characteristic of Korsakoff's syndrome, which is associated with severe memory impairment and confabulation. Alzheimer's disease is a neurodegenerative disorder primarily associated with amyloid plaques and tau tangles in the brain, while phenylketonuria is a genetic disorder that affects the metabolism of phenylalanine. Down syndrome is a chromosomal disorder caused by an extra copy of chromosome 21, and is not typically associated with damage to the dorsomedial thalamus or mamillary bodies.
