Amnesia in Harry Potter
After his memory charm backfired on him due to Ron's broken wand, Professor Lockhart's memories were completely wiped. From that point on, Professor Lockhart suffered complete retrograde amnesia, which is the inability to recall memories that occurred prior to an injury to the head. He was later admitted to St. Mungo's Hospital for Magical Maladies and Injuries as a permanent resident, which is discovered in the fifth book of the series, Harry Potter and the Order of the Phoenix.
