The trigger: A variety of external and internal factors can trigger a migraine attack in certain individuals who may have a genetic or neurochemical predisposition to migraine. External triggers such as weather-related changes, high humidity, sensory input such as flashing lights, sunlight, loud noises, and exposure to odors, smoking, alcohol (red wine) and stress have all been implicated in migraine.
