Amnesia is the loss of the ability to recall memories of past events.[1] This may be a partial or complete loss during a specific period of time.[1] Generally the ability to perform skills is retained and only the ability to remember facts is lost.[1] The loss of memory may be brief, permanent but stable, or progressively worsening.[1]
