A migraine causes paroxysmal unilateral headaches accompanied by vomiting. Complex biochemical changes, for instance, an increased amount of serotonin and prostaglandin in the blood plasma, provoke a short spasm of the intracranial vessels followed by a continuous expansion of the extracranial arteries.


The spasm is the foundation of photopsia and other focal symptoms. Besides, the expansion of the vessels is the direct cause of headaches. In a classical case, the migraine attack begins with a transient (sometimes ophthalmic) scotoma. As a result, patients often feel pain in the head at large.


Nausea and vomiting usually accompany the pain. The attack lasted several hours. Unlike a classical, ordinary migraine has no visual aura. It features diffuse pain that arises in the morning and lasts several days. Rest provokes cephalalgia (a headache at the weekend). This illness variant is characteristic of women suffering from being overweight.

Migraine attack

Cases during which the attack is accompanied by hemiplegia, aphasia, and ophthalmoplegia are known as associated migraine. The frequency and seriousness of Migraine attacks vary greatly: 50 per cent of patients have attacks less than once per week. A migraine is a widespread disease affecting 5-10 per cent of the population. The condition usually begins during adolescence or, less often, during childhood.
