H.M. had anterograde amnesia, which made it difficult for him to form new memories. Questions about recent events or specific recent interactions, like whether he had visitors the day before yesterday, would be challenging for him to answer. Basic factual knowledge or procedural memory, such as his mother's maiden name, the number of days in 3 weeks, or simple arithmetic, would generally remain intact.
