According to one of my numerous doctors, the chances of a complete remission drops precipitously after two years. In younger people it can go away and disappear for all practical purposes. Older persons who experience remission are always on the verge of it returning. Even those who have remission it often will not be complete.

Most sufferers, I believe, are searching more for a plateau where the symptoms are as manageable as possible.

Age of onset and lenght of time till treatment are critical to good outcomes.
