Abstract:
Botulinum toxin type A (BTX-A) treatment for cervical dystonia is traditionally considered a purely symptomatic treatment. BTX-A blocks acetyl choline exocytosis for 3-6 months and most patients require reinjection after this period. We report on 6 patients (mean age 41.6 years, range 18-69) with idiopathic cervical dystonia who were treated with BTX-A injections and became asymptomatic for 2-4 years. Four patients showed remission after the first BTX-A treatment, 1 patient after the second set of injections and 1 after the third session. Amelioration of neck dystonia was observed within 1-4 weeks after the last BTX-A treatment and all 6 patients are symptom-free, off antidystonic medications for over 2 years. The possibility that BTX-A treatment may increase the chances of development of clinical remission in patients with idiopathic cervical dystonia is discussed.
