For cases of secondary ARD, the prognosis depends on the underlying cause and success of treatment. For cases of idiopathic ARD, the prognosis is guarded and many of them are likely to relapse when treatment is stopped, which may require a prolonged or life-long treatment. Some cases, however, do resolve and only require a short term treatment.
