11.2.3 Headache attributed to craniocervical dystoniaHartmut Gobel2018-01-31T13:39:36+00:00
Description:
Headache caused by dystonia involving neck muscles, with abnormal movements or defective posturing of the neck and/or head due to muscular hyperactivity.
Diagnostic criteria:
- Neck and posterior head pain fulfilling criterion C
- Craniocervical dystonia is demonstrated by abnormal movements or defective posturing of the neck and/or head due to muscular hyperactivity
- Evidence of causation demonstrated by at least two of the following:
- pain has developed in temporal relation to the onset of craniocervical dystonia
- pain has significantly worsened in parallel with progression of the craniocervical dystonia
- pain has significantly improved or resolved in parallel with improvement in or resolution of the craniocervical dystonia
- pain location corresponds to the location of the dystonic muscle(s)
- Not better accounted for by another ICHD-3 diagnosis.
Comments:
Focal dystonias of the head and neck accompanied by 11.2.3 Headache attributed to craniocervical dystonia are pharyngeal dystonia, spasmodic torticollis, mandibular dystonia, lingual dystonia and a combination of the cranial and cervical dystonias (segmental craniocervical dystonia).
Pain is presumably caused by local muscle contraction and secondary changes in sensitization.
