PAWOI is said to possibly be a factor involved in a variety of neurological symptoms, including visual snow, loss of vision, increased afterimages, tinnitus, and others.
At present, PAWOI is usually diagnosed solely based on the patient's current and past symptoms.
It is possible that an "overactive brain" or a chemical imbalance underlies the disorder.
Various medications have been tried as treatment, notably acetazolamide,[3] valproate,[4] lamotrigine,[1] topiramate, and furosemide.
