Purpose Of Review:
To highlight and critically discuss the possibility that breathing abnormalities during hypersomnolent episodes are an additional clinical feature of Kleine-Levin Syndrome (KLS).
Recent Findings:
A computerized literature search of breathing abnormalities in patients with KLS disclosed two old and a single recent publication describing a total of six patients with sleep apnea during hypersomnolent episodes.
Summary:
Owing to scarce reports on complete polysomnography during and in-between hypersomnic episodes of KLS, the possibility that breathing abnormalities are an additional clinical feature of this unique episodic sleep syndrome should be further studied.
