There are occasional reports of dystonia symptoms going into remission. Given the research and prognosis implications of this, investigators did a systematic review of reports of remission in the medical literature.
They reviewed data from 2,551 cases with reports predominantly from individuals with cervical dystonia or blepharospasm/Meige syndrome. Complete remission was reported in 12% and partial remission for 4% of cases. Remission rates were higher in cervical dystonia (15%) than in blepharospasm/Meige (6%). Remission occurred on average 4.5 years after onset of symptoms. However, the majority of patients (64%) experienced a return of symptoms.
The data suggested that patients with remission were significantly younger at symptom onset than patients without remission. The investigators called for additional study into this important phenomenon.
