Loud snoring and daytime sleepiness are the main complaints; however, the condition may present with a variety of symptoms and signs. Case Report: A 65-year-old woman was admitted to neurology ward with the diagnosis of intractable seizures. The physical examination revealed papilledema and huge obesity with body mass index of 41. Brain imaging was unremarkable. The pressure of cerebrospinal fluid was 33 cm H2O. As respiratory distress was observed, pulmonary evaluations were conducted. Finally, an overnight polysomnography confirmed the diagnosis of severe OSA. Positive airway pressure removed the symptoms. Conclusion: This presentation suggests that severe OSA should be considered as a differential diagnosis for epilepsy and a probable cause of raised intracranial pressure, especially at the presence of obesity.       https://jss.tums.ac.ir/index.php/jss/article/view/3 https://jss.tums.ac.ir/index.php/jss/article/download/3/30
