Abstract
- Cases showing memory disturbances with isolated retrograde memory without any definitive brain lesions are classified as dissociative amnesia. Improvements in imaging techniques have allowed the organic causes of this disease to be identified in several recent cases. Several studies have diagnosed cases of memory disorders as pure retrograde amnesia (PRA). The patient reported here had no psychiatric disorder and had normal MRI results, but showed hypometabolism in PET that met the criteria for PRA.
