Lesions in the anterior temporal lobes can lead to issues with processing and retrieving past memories, which is characteristic of retrograde amnesia. This condition affects the ability to recall information that was learned before the onset of amnesia. Since the medial temporal structures, which are crucial for the formation of new memories, are intact, anterograde amnesia (difficulty forming new memories) is less likely. Korsakoff's syndrome is associated with chronic alcoholism and thiamine deficiency, not specifically with anterior temporal lobe damage. Implicit memory, which involves unconscious memory like skills and conditioned responses, is not typically affected by anterior temporal lobe damage.
