The symptoms of<unk>  themselves are not inherently harmful, and are often not frightening to the person experiencing them. Since there is no established treatment for<unk> , prognosis varies from patient to patient and based on if an underlying cause has been identified. In cases of<unk>  caused by underlying conditions, symptoms typically occur during the course of the underlying disease and last anywhere from a few days to months. In most cases, symptoms of<unk>  disappear either spontaneously, with treatment of underlying causes, or after reassurances that symptoms are momentary and harmless. Some people do not experience any more episodes of symptoms after their first experience, while others have repeat episodes before symptoms resolve. Other people continued to experience episodes years after the initial experience, sometimes with the development of new visual disorders or migraines.
