• A. Dementia
• B. Amnestic Disorders
• C. Delirium
• D. Major depressive disorder

Answer: (B)

Amnestic disorders are defined by memory impairment that is the primary feature, with other cognitive functions remaining largely intact. Korsakoff's syndrome is a classic example of this pattern, typically arising from thiamine deficiency often linked to chronic alcohol use. In Korsakoff’s, there is severe difficulty forming new memories and recalling past events, while other thinking abilities can be relatively preserved, illustrating the memory-centered profile described. Dementia involves a broader, progressive decline across multiple cognitive domains (such as language, executive function, and memory), not memory in isolation, so it doesn’t fit the description. Delirium presents as an acute, fluctuating disturbance in attention and cognition with altered consciousness, where memory problems are part of a wider cognitive disruption. Major depressive disorder can bring cognitive complaints, but the hallmark is mood disturbance with secondary, not primary, memory impairment.
