Some people that suffer from classic migraines have experienced a seizure, triggered by the aura, during or directly after a migraine attack. Many doctors define this occurrence as Migralepsy.

Classic Migraines

A classic migraine begins with the aura stage, followed by severe and throbbing headache pain.


According to the Mayo Clinic, the aura stage of a migraine affects 20 per cent of migraineurs. An aura can include visual, sensory, motor, or verbal disturbances. Visual disturbances include blind spots, flashing lights, and zig zag lines.


Seizures range in severity from hardly noticeable to debilitating. A seizure occurs when a sudden surge of electrical activity in the brain causes physical and sensory disturbances, such as convulsing and blacking out. More than 30 types of seizures have been identified with two main categories, focal seizures and generalised seizures, says the National Institute of Neurological Disorders and Stroke.

The Connection

Basilar migraines and migraines with a normal or prolonged aura can trigger a seizure. Cerebral infarction, caused by migraines, also causes seizures in some people.


The aura of a seizure and the aura of a migraine are similar; sometimes only the duration of the aura can differentiate the two. If you think you have experienced a seizure talk to you health care professional right away.
