Korsakoff syndrome following chronic subdural hematoma

We describe a patient who developed Korsakoff syndrome following a spontaneous chronic subdural hematoma. The present case demonstrates persistence of both amnesia and confabulation long after recovery from the acute phase of spontaneous chronic subdural hematoma. There are few reports describing persistent amnesia with confabulation following brain damage. We considered that chronic subdural hematoma in the bilateral frontal and temporal lobes caused amnesia and confabulations, and these conditions persisted as a result of organic atrophic changes of both the frontal and temporal lobes due to long-term compression by chronic subdural hematoma.
