In Korsakoffs syndrome, recent memory is impaired, that means both short term and long term memories are involved. However, only long-term memory of recent past involved say, for example, 20-30 minutes or 1 hour.Remote memory is long-term memory of more distant past, which is not impaired in Korsakoffs syndrome.
