Persistent aura without infarction (PAWOI) is a little-known condition, first described under the designation prolonged migraine aura status,[1] that is not yet fully understood. PAWOI is said to be a possible cause of a variety of neurological symptoms, including visual snow, loss of vision, increased afterimages, tinnitus, and others.[2] However, the pathogenesis of PAWOI is unknown; in other words, it is not known exactly what causes these symptoms. Furthermore, it is not clear which medical examinations are useful in diagnosing PAWOI. At present, PAWOI is usually diagnosed solely based on the patient's present and past symptoms. It may be possible that an overactive brain or a chemical imbalance is partly to blame for the disorder. Different medication has been tried as treatment, notably acetazolamide,[3] valproate,[4] lamotrigine,[5] topiramate, and furosemide.[6]
