ABSTRACT: To observe the clinical features of migraine based on out-patient clinic data and provide help for the diagnosis and treatment of migraine.
In a retrospective study of 309 patients with migraine, we investigated the clinical characteristics of migraine of both genders and different types, and the risk factors for MOH transformed from migraine.
The female to male ratio was about 3:1, 76.1% of the patients had triggering factors. The most common characteristics of headache were moderate to severe intensity of the pain (97.7%), aggravation by routine physical activity (75.1%), and association with nausea (90.9%) and/or vomiting (70.6%). There were significant differences in some clinical characteristics of migraine in females as compared with those in males and in patients with migraine without aura (MWOA) as compared with those with aura (MWA). The risk factors for MOH transformed from migraine were elder age of onset, high attack frequency and the analgesics frequently used (P < 0.05).
It is suggested that carefully collecting the characteristics of headache, triggering factors and therapeutic history is the foundation of correct diagnosis and effective treatment for migraine.
