Abstract

Cluster headaches (CH), characterized by strictly unilateral pain localized in or around the eye and accompanied by ipsilateral autonomic features, are the most painful form of primary headache. Probable cluster headache (PCH) is a subtype of CH fulfilling all but one diagnostic criteria for it: for example, with no ipsilateral autonomic features. CH is associated with severe pain and has a considerable impact on social functioning and quality of life. Like CH, PCH without ipsilateral autonomic features (PCHWOIAF) may be associated with severe pain and considerable impact, but PCHWIAF has not been studied. The present study aimed to clarify the clinical profile of PCHWIAF.

Highlights

  • Cluster headaches (CH), characterized by strictly unilateral pain localized in or around the eye and accompanied by ipsilateral autonomic features, are the most painful form of primary headache

  • Seven patients who had been diagnosed with PCHWOIAF according to the 2nd edition of the International Classification of Headache Disorders were compared with 86 patients with CH

  • Patients with PCHWOIAF should receive the same level of treatment as patients with cluster headaches
