Objective. - To evaluate the prevalence of associated headache (HA) pain with craniocervical dystonia and the therapeutic effect of BoNT-A injections on the HA component when injected for cervical dystonia. Background. - HA associated with craniocervical dystonia is a recent formally codified entity, but has not been systematically studied. Methods. - We identified 44 subjects from three movement disorder clinics who presented with craniocervical dystonia and concurrent HA pain. The subjects were injected with botulinum toxin type A (BoNT-A) and prospectively evaluated with the Toronto Western Spasmodic Torticollis Rating Scale (TWSTRS), headache diaries, Headache Impact Test (HIT-6), and Migraine Disability Assessment Scale (MIDAS), along with HA pain anatomy and adverse events, at baseline, and at 4, 8, and 12 weeks post-injection. Results. - As expected, all aspects of the TWSTRS robustly improved. Headache diaries and the HIT-6 also improved at 4, 8, and 12 weeks post-injection. Sections of the MIDAS improved, and adverse events were minimal. Conclusion. - BoNT-A safely improves headache associated with craniocervical dystonia when administered for the primary condition of craniocervical dystonia.
