[Remission of atypical and refractory cluster headache after topiramate administration]

Abstract

Cluster headache is the third most frequent type of primary cephalgia only exceeded in frequency by tension-type headache and migraine. Cluster headache is characterized by periodic attacks of unilateral excruciating pain and accompanying autonomic features. It is arguably the most disabling form of primary headache. Therefore, prompt recognition of this disorder is necessary to provide an opportunity for effective treatment. We report on a patient with cluster headache, who complained about an atypical interval of dull headache between the cluster attacks, thus excluding the differential diagnosis of hemicrania continua. The common drugs for acute cluster attacks proved to be ineffective as well as prophylactic treatment with steroids and verapamil. Only administration of topiramate led to relief of pain.
