Abstract

Prolonged remission of dystonia occurs rarely; however, well-documented cases are lacking. We report the clinical characteristics and course of four patients with botulinum toxin (BoNT)-associated prolonged remission of idiopathic cervical dystonia. Mean age at onset was 40 years. All had a relatively short duration of symptoms (mean 10.3 months), and with remission occurring after ≤ 3 treatments with BoNT. At last examination, the remission duration was 2-5 years. In the two cases that subsequently relapsed after 4-5 years, there was an altered phenomenology and worsened severity than at the onset. Recognizing this rare phenomenon has valuable clinical implications.
