title: Persisting hyperekplexia after idiopathic, self-limiting brainstem encephalopathy.
abstract: Symptomatic hyperekplexia is a relatively rare entity, but has been documented in various, mostly brainstem diseases. We report the clinical and neurophysiologic vignette of a patient with a self-limiting, possibly inflammatory brainstem encephalopathy. Trismus was the presenting feature, but she later developed hyperekplexia. Although most brainstem features resolved spontaneously, the hyperekplexia has persisted.
