Exploding Head Syndrome: a Review

Abstract

Purpose of Review

To explain our current understanding of exploding head syndrome (EHS), an unusual and underreported sensory parasomnia.

Recent Findings

Based on findings from recent studies of EHS, the prevalence is higher than previously suggested by the literature, which historically has consisted mostly of case reports. The typical presentation also has been better illustrated by recent case series, and diagnostic criteria have been defined. Its pathophysiology is still unclear.

Summary

EHS is underrecognized and its symptoms are alarming, but a review of our current state of knowledge will allow physicians to make a diagnosis of this benign condition with greater confidence.
