Trigger factors in migraine patients

The objective of this study was to examine potential trigger factors in migraine patients. A total of 126 migraine patients were interviewed about possible trigger factors for migraine. The most common trigger factors were emotional stress (79%), sleep disturbance (64%) and dietary factors (44%). Sleep and stress were significant trigger factors in patients with migraine with aura, whereas environmental factors were important trigger factors in patients with migraine without aura. Stress, sleep and environmental factors were important trigger factors in women and differed significantly from men. Trigger factors are frequent in migraine patients, and avoidance of such factors may result in a better control of the disorder.
