Study on Migraine and Headache in Epileptic Patients

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to collect data from patients who are diagnosed with epilepsy and are followed up in epilepsy clinics.

Detailed Description
-----------------
Headaches and epilepsy are chronic disorders with episodic manifestations characterized by recurrent attacks of nervous system dysfunction with a return to baseline between attacks. Although it is not uncommon that patients with epilepsy suffer from headaches, the relations between seizures and headaches is multi-factorial. Headaches may occur immediately before (preictal), during (ictal), or after (postictal) a seizure. In addition to seizure-associated headaches, patients often experience headaches that are not temporally related to seizures-interictal headaches. Moreover, epidemiological studies indicate an association of migraine and epilepsy with an increased prevalence of migraine in patients with epilepsy. Up to now, there is still limited information about the relationship between the frequency of seizure attacks and headache occurrences. Thus, we purpose this study to investigate the incidence of headaches, to explore the relationship between seizure attacks and headache occurrences, to classify the headache, and to document the frequency, characteristics, and effects of migraine and headaches among patients with epilepsy. This study is a multi-centre survey to collect data from patients who are diagnosed with epilepsy and are followed up in epilepsy clinics. Patients can only participate in this study after signing and dating the inform consents. There are two stages of this study: Stage I: On enrollment, data on demographic characteristics, epilepsy profile, seizure frequencies, and epilepsy treatment would be obtained. Body weight and height would be measured. Information of prior headache occurrences and their relationships with seizures would also be collected. Stage II: Patients enrolled into this study will be divided into three group: patients who are seizure free for past 6 months, patients with > 1 attack every month within past 6 months, and other patients. Participants of each group will be enrolled into Stage II for 24-week follow-up. Information of seizure attacks, headache occurrences, and treatment will be collected. This is an observational study and no study drug is administered.
