INTRODUCTION The revised International Headache Society (IHS) criteria for cluster headache are: attacks of severe or very severe, strictly unilateral pain, which is orbital, supraorbital, or temporal pain, lasting 15 to 180 minutes and occurring from once every other day to eight times daily. METHODS AND OUTCOMES We conducted a systematic review and aimed to answer the following clinical que...

Cluster headache causes severe unilateral temporal or periorbital pain, lasting 15 to 180 minutes and accompanied by autonomic symptoms in the nose, eyes, and face. Headaches often recur at the same time each day during the cluster period, which can last for weeks to months. Some patients have chronic cluster headache without remission periods. The pathophysiology of cluster headache is not ful...

BACKGROUND Cluster headache is a primary headache by definition not caused by any known underlying structural pathology. However, symptomatic cases have been described, for example tumours, particularly pituitary adenomas, malformations, and infections/inflammations. The evaluation of cluster headache is an issue unresolved. CASE DESCRIPTION I present a case of a 24-year-old patient who prese...

Background: Secondary cluster headache following carotid endarterectomy (CEA) is a rare condition and may help us understand the pathophysiology of primary cluster headache. Summary: We describe 2 patients diagnosed with cluster headache, fulfilling the ICHD-IIIB criteria, following CEA. Neither of the patients had headache prior to surgery. They both responded to treatment with oxygen and vera...

We investigated the mode of inheritance of cluster headache in 370 families. The probands were from a neurological clinic in Jutland and two departments of neurology in Copenhagen County, Denmark. The criteria of the International Headache Society were used. The patterns of segregation of cluster headache were assessed by complex segregation analysis performed with the computer program POINTER....
