Blackouts are similar to episodes of transient global amnesia in that they are discrete episodes of anterograde amnesia that occur in association with alcohol intoxication.> The periods of amnesia can be particularly distressing when persons fear that they have unknowingly harmed someone or behaved imprudently while intoxicated.> During a blackout, persons have relatively intact remote memory but experience a specific short-term memory deficit in which they are unable to recall events that happened in the previous 5 or 10 minutes.> Because their other intellectual faculties are well preserved, they can perform complicated tasks and appear normal to casual observers.> The neurobiological mechanisms for alcoholic blackouts are now known at the molecular level; alcohol blocks the consolidation of new memories into old memories, a process that is thought to involve the hippocampus and related temporal lobe structures.
