6.5.1.2 Persistent headache or facial or neck pain attributed to past cervical carotid or vertebral artery dissection

Description:

Headache caused by cervical carotid or vertebral artery dissection and persisting for more than 3 months after the dissection has stabilized.

Diagnostic criteria:
  1. Headache previously diagnosed as 6.5.1.1 Acute headache or facial or neck pain attributed to cervical carotid or vertebral artery dissection and fulfilling criterion C
  2. The dissection has stabilized, spontaneously or through treatment
  3. Headache has persisted for >3 months after stabilization of the dissection
  4. Not better accounted for by another ICHD-3 diagnosis.
Comment:

A few studies have documented headaches meeting the criteria for 6.5.1.2 Persistent headache or facial or neck pain attributed to past cervical carotid or vertebral artery dissection. Research is needed to identify risk factors for such persistent headache; a previous history of 1. Migraine may play a role, as may anxiety/depression.
