KC

Who is KC?

Patient KC is a widely studied Canadian memory disorder patient who has been used as a case study in over 20 neuropsychology papers over the span of the past 25 years. In 1981, KC was involved in a motorcycle accident that left him with severe anterograde amnesia, as well as temporally graded retrograde amnesia. Unlike other amnesic patients, KC has his semantic memory intact, but lacks episodic memory with respect to his entire past. As a case study, patient KC has been linked to the breakdown of the single-memory single-locus hypothesis regarding amnesia, which states that an individual memory is localized to a single location in the brain.
