Epilepsy has been linked to migraine headaches. They are comorbid conditions, which means if you have one of them, there is a greater likelihood of having the other. In most cases, however, it is a matter of a patient with two different neurologic conditions with occasional overlapping of symptoms. Patients with epilepsy may at times have a "postictal" or "post-seizure" headache. This headache is diffuse, throbbing, and moderate and subsides over a number of hours.
