title: Kleine-Levin syndrome with comorbid iron deficiency anemia.
abstract: Kleine-Levin syndrome (KLS) is a rare chronic sleep disorder of unknown etiopathology, which typically occurs in adolescent males. Although the severity of symptoms and disease course varies between the KLS patients, it usually resolves spontaneously, but sometime comorbid conditions may worsen the symptoms. Herein, we report a case of KLS who presented with severe episodic hypersomnia. During episodes, the patient used to sleep as long as 20 h in a day, affecting his daily living activities. All the relevant investigations including electroencephalography, magnetic resonance imaging of brain and cerebrospinal fluid analysis were normal except for severe iron deficiency anemia (IDA). In our patient, the severity of symptoms worsened due to coexistent IDA. The treatment of IDA along with modafinil decreased the severity of symptoms and shortened the hospital stay during episodes. This might be the first case report of KLS with comorbid IDA.
