Understanding Amnesia

• Anterograde amnesia is the inability to store any new long-term memories following a brain injury. A patient with anterograde amnesia has an intact STM, so can process sensory information in that moment of time. But they are unable to lay down any new memories that last beyond a few minutes.
• Retrograde amnesia is where a patient who has suffered a brain injury cannot remember information from before the injury.
• It is possible for people with retrograde amnesia to regain some or all of their lost memory.
