Amnestic syndrome due to bilateral isolated sequential hippocampal infarctions: A case presentation

Abstract

Transient global amnesia, acute ischemic stroke, seizures and status epilepticus, limbic encephalitis and various types of encephalopathies are included in differential diagnosis of acute-onset amnestic syndrome. Isolated hippocampal infarction is a rare cause of acute-onset amnestic syndrome. In this case presentation, we report a patient who developed permanent and severe cognitive impairment after acute-onset amnestic syndrome due to bilateral isolated hippocampal infarctions occurring nine months apart and a review of the pertaining literature is presented.
