Stress as a precipitating factor in migraine

Stress is the precipitating factor in migraine which is most commonly recognized by patients. There are many affected who describe headaches brought on by stressful situations and events, although they also speak of the onset of their attacks during the period of calm immediately after such moments of stress. There are however few objective works in the literature which study the relationship between stress and migraine. In the present work we review that literature which does exist concerning such a relationship.
