Kleine-Levin syndrome (KLS) is a rare disorder (around 1.5 cases per million population), often presenting with triad of recurrent episodes of hypersomnia, hyperphagia, and hypersexuality. However, cases of atypical KLS with features opposite to that being commonly reported are often misdiagnosed as psychosis and present as a diagnostic challenge for the physicians, psychiatrists, and neurologists. We describe a case of atypical KLS which was misdiagnosed as unspecified nonorganic psychosis previously, highlighting the various points which would be helpful in identifying and diagnosing cases of atypical KLS in future.
