Overview
MRI
- Psychogenic amnesia is defined by the lack of structural damage to the brain, but upon functional imaging, abnormal brain activity can be seen. Tests using functional magnetic resonance imaging suggest that patients with psychogenic amnesia are unable to retrieve emotional memories normally during the amnesic period, suggesting that changes in the limbic functions are related to the symptoms of psychogenic amnesia.[1]
- In transient epileptic amnesia MRI is usually normal. However, in some patients frontal and temporal lobe abnormalities have been observed.[2]
