Question

Quizplus · Accepted Answer

Anterograde amnesia refers to the inability to form new memories, while retrograde amnesia refers to the inability to recall past memories. Therefore, Option A accurately differentiates between the two types of amnesia. Option B is incorrect because it provides inaccurate or incomplete definitions of both amnesias. Option C is incorrect because although damage to the hippocampus can cause anterograde amnesia, damage to the frontal lobe can cause retrograde amnesia. Option D is incorrect because retrograde amnesia is not typically caused by prenatal teratogens.
