Overview
Amnesia can be divided into two broad groups, retrograde amnesia and anterograde amnesia. Anterograde amnesia is the inability to form new memory and retrograde amnesia is the loss of memory prior to the onset of amnesia.
Classification
- Amnesia can be divided into two broad groups:
- Anterograde amnesia: The inability to form new memory. Past memory is intact.
- Retrograde amnesia: The loss of memory prior to the onset of amnesia. Patient can form new memories.
- Following are types of amnesia, these can features of anterograde, retrograde or both:
- Dissociative Amnesia: Temporary, episodic retrograde memory loss. Cause is psychological in origin. Repressed amnesia is seen in these patients where they are unable to recall a stressful or traumatic incident from the past due to psychological defense mechanism. Dissociative fugue has been observed in these patients. Dissociative Amnesia is also referred to as psychological amnesia.[1][2]
- Post-traumatic Amnesia: Amnesia that follows head trauma could be temporary or permanent. The span of memory loss is uncertain it could present with retrograde, anterograde or combined. Extent of injury and duration of loss of consciousness are important prognostic factors in determining the severity of amnesia. [3]
- Infantile Amnesia
- Drug-Induced Amnesia
- Amnesia in Korsakoff’s Syndrome
- Selective Amnesia
- Epileptic Amnesia
- Lacunar amnesia
