Unpredictable Kleine-Levin syndrome: A mysterious phenomenon?

Correspondence to Author: Swarndeep Singh,

Department of Psychiatry.

Introduction: With only 1.5 instances per million people, Kleine-Levin syndrome (KLS) is an uncommon condition that frequently manifests as a triad of repeated bouts of hypersomnia, hyperphagia, and hypersexuality. Nonetheless, instances of atypical KLS with characteristics dissimilar to those frequently documented are frequently mislabeled as psychosis and provide a diagnostic difficulty for medical professionals, psychiatrists, and neurologists. We present a case of atypical KLS that was previously misdiagnosed as undefined nonorganic psychosis, emphasizing the several aspects that could be useful in recognizing and classifying atypical KLS cases in the future.
