The recovery is often gradual, the memory slowly reclaiming isolated events while others are still missing. In another form, only certain isolated events are lost to memory.Īmnesia victims usually have a good chance of recovery if there is no irreparable brain damage. When amnesia results from a single physical or psychologic incident, such as a concussion suffered in an accident or a severe emotional shock, the victim may forget only the incident itself the victim may be unable to recall events occurring before or after the incident or the order of events may be confused, with recent events imputed to the past and past events to recent times. Anterograde amnesia is the inability to create new memories. More severe cases can cause someone to not remember much more, even to the extent of now knowing their own name. Rarely is the memory completely obliterated. Retrograde amnesia is the backward loss of memories and is distinguished from forward anterograde amnesia, which is the inability to acquire new memories. Anterograde amnesia refers to a severe and permanent inability to learn new information in the presence of otherwise normal intelligence, attention span. Retrograde amnesia is the loss of memories, such as what happens when someone is in a car crash but they can't remember how the crash happened. The technical term for this is repression. Retrograde Amnesia is the loss of ability to recall episodic memories and many times semantic memories that happened before a brain injury occurred. Psychologic factors may also cause amnesia a shocking or unacceptable situation may be too painful to remember, and the situation is then retained only in the subconscious mind. Amnesia is usually the result of physical damage to areas of the brain from injury, disease, or alcoholism.
