Abstract
Acute and complete ischemia of the hippocampi represents a rare cause of amnesia. This paper describes the features of four such cases presenting to a single tertiary care center over a 3-year period. Interestingly, in three instances, toxicology screening was positive for opioids at the time of presentation, while in the fourth, there was a known, reportedly remote, history of heroin use. Taken together with the known literature on the topic, complete hippocampal ischemia appears at least highly suggestive of a toxic exposure. Further case finding is necessary to better understand the etiology, nature, and prevalence of this unusual clinico-radiologic entity.Keywords
