Genetic factors

About 60% of migraine patients have a family history, and the risk of migraine in their relatives is 3 to 6 times that of the general population. No consistent Mendelian inheritance pattern has been found in familial migraine patients, reflecting the interaction between different penetrances and polygenic genetic characteristics and environmental factors.

Migraine attacks can be triggered by certain foods and drugs, including cheese containing tyramine, meat and pickled foods containing nitrite preservatives, chocolate containing phenylethylamine, food additives such as monosodium glutamate (MSG), red wine and wine, etc. Medications include oral contraceptives and vasodilators such as nitroglycerin. Other environmental and mental factors such as tension, overwork, emotional excitement, excessive or insufficient sleep, menstruation, and strong light can also trigger it.

Some patients also experience mental disorders, fatigue, yawning, loss of appetite, general discomfort, etc. before the onset of the disease. Pain can also be induced in women during menstruation, drinking, and hunger. The headache usually worsens slowly, with recurrent unilateral or bilateral frontal and temporal pain that is pulsating. When the pain persists, the symptoms may be complicated by contraction of the neck muscles. It is often accompanied by symptoms such as nausea, vomiting, photophobia, phonophobia, sweating, general malaise, and scalp tenderness.

Migraine with aura occurs in about 10% of migraine patients. Prodromal symptoms such as fatigue, inattention, and yawning may occur hours to days before an attack. Before or when a headache occurs, reversible focal neurological symptoms are often present as precursors. The most common are visual precursors, such as blurred vision, dark spots, flashes, bright spots or lines, or distorted vision; the second most common are sensory precursors, which are mostly distributed in the face-hand area; speech and motor precursors are rare.
