Investigation of Demographic and Clinical Features in 131 Iranian Patients with Cluster Headache
Background: Cluster headache is defined as ‘unilateral, excruciatingly severe attacks of pain principally in the ocular, frontal, and temporal areas recurring in separate bouts along with daily or almost daily attacks for weeks to months usually with ipsilateral lacrimation, conjunctival injection, photophobia and nasal stuffiness and/or rhinorrhoea’.
Methods: This descriptive study was performed in the Isfahan Medical University from June 2006 to June 2007. 131 patients with definite cluster headache were selected randomly. Data was taken from past history and presenting features of patients.
Results: Among with 131 Iranian patients investigated in our study (referred with possible diagnosis of cluster headache from other centers), there were: 120 male, 11 female, 68.7% 20 to 40 years old, 67% with abrupt onset headache, 90 with pulsatile pain, 30 with nonpulsatile pain, 2 with both types, 69.4% with less than 60 minute duration, 38.8% with similar time occurrence of headache, more prevalent autonomic sign, lacrimation, nostril block, vomiting, prominence of temporal artery, rinorrhoea, petosis, and profuse sweating, site of headache: 101 around the orbit, 19 far from the orbit, 96 with seasonal relationshop, 102 with episodic pattern, 29 with chronic form, Free period: 60%: 7 to 12 months. Related foods: dairy products, onions, vinegar, pickles, fatty foods, fast food, eggs, toasted foods, pungent foods, cucumbers and potatoes. Familial and childhood cluster headache, non alcohol consumption: 22 patients, smoking: 52 patients, history of head trauma: 15 patients.
Conclusion: On the basis of this study, maybe there is a regional and race difference among different studies. According to treatability of this type of headache, and morbidity and costs that are produced by this disease, more extensive studies on the base of prevalence, predisposing factors, different aspects of treatment, and prophylactic treatments should be taken to provide patients with more suitable and effective helps.
