Brain MRI findings in patients with Idiopathic Hypersomnia

Idiopathic hypersomnia is a central nervous system hypersomnolence disorder that manifests as pathologic daytime sleepiness despite sufficient sleep at night. Hypersomnia is associated with higher healthcare costs and significant socioeconomic burdens for affected patients [1]. Formal diagnostic criteria for idiopathic hypersomnia, through the International Classification of Sleep Disorders, require the presence of sleepiness lasting at least three months, accompanied by the demonstration of short sleep latency, without abnormal REM sleep, on multiple sleep latency test or the documentation of persistently long sleep times by actigraphy or polysomnography [2].
