Delayed Appearance of Klein-Levin Syndrome Caused by Traumatic Brain Injury: A Case Report

Abstract

Background: The combination of hypersomnia and any of: hyper-phagia, hyper-sexuality, or mood changes is known as Klein-Levin Syndrome. This syndrome is quite infrequent and mostly restricted to adolescent males. Case Description: A young patient with KLS is presented in this report. He was presented with relapsing-remitting hypersomnia and irritability more than two years after incurring a traumatic brain injury. Magnetic resonance imaging (MRI) showed hyperintensity in the posterolateral part of the right temporal region, matched with the brain injuries caused by the old trauma. His extremely long sleep episodes forced medical team to provide him with some necessary basic cares such as nasogastric tube and urinary catheter. Five consecutive weeks of taking modafinil got his sleep pattern back to normal. Conclusion: In addition to medical treatment which is inevitable for severe cases, family and social support is extremely vital for managing KLS patients.
