Amnesia due to Lesions Confined to the Hippocampus: A Clinical-Pathologic Study
1Dartmouth Medical School and Veterans Administration Medical Center, White River Junction, Vermont.
Abstract:
Reported here is the case of a 65-year-old man who suffered a burst of severe, repetitive generalized seizures (status epilepticus). On recovery of consciousness he was left with a profound impairment of memory, which remained unchanged for the subsequent 30 months of his life. During this period the cognitive defect was fully documented. Careful neuropathologic examination disclosed the presence of remarkably discrete lesions, confined to the hippocampus on each side. Because of the rarity of well-documented instances of this type and their importance in the study of memory function, we are reporting our case in some detail.

Role of Hippocampus in Memory
Amnesia
The severity and duration of memory loss vary depending on the type and underlying cause. Amnesia is classified into two main types: retrograde and anterograde.
Retrograde amnesia is marked by the loss of memories formed before the onset of the condition. Patients may recall distant past events but often forget those occurring shortly before the incident.
Anterograde...
