Chronic medication is often needed, with relapses of individuals reaching rates over 90% in those not following medication indications and almost to 40% in those complying with medication regimens in some studies.[1] Compared to adults, a juvenile onset has in general a similar or worse course, although age of onset predicts the duration of the episodes more than the prognosis. A risk factor for a worse outcome is the existence of additional (comorbid) pathologies.[2]
