Quizplus · Accepted Answer

Korsakoff's syndrome is a neurological disorder caused by long-term alcohol abuse. It is characterized by memory deficits and confabulation (hallucinations or invented memories), but intellectual abilities remain intact. Proactive interference is a memory retrieval problem, Alzheimer's disease is a neurodegenerative disorder that primarily affects older adults and is characterized by memory loss and cognitive decline, and anterograde amnesia is the inability to form new memories. None of these choices fully fit Pierre's symptoms, making D the best choice.
