Headache in epilepsy: prevalence and clinical features

Area of Science:

• Neurology
• Epileptology
• Headache Medicine

Background:

• Epilepsy and headache are common neurological disorders with a debated relationship.
• Understanding headache prevalence and features in epilepsy is crucial.

Purpose of the Study:

• To determine the prevalence and clinical characteristics of inter-ictal (inter-IH) and peri-ictal headache (peri-IH) in epilepsy patients.
• To explore the association between headache types and epilepsy features.

Main Methods:

• A cohort of 388 epilepsy patients (≥17 years) were interviewed using ICHD-II criteria.
• Statistical analyses (chi-squared, t-test, Mann-Whitney) compared clinical variables.

Main Results:

• 48.5% experienced inter-ictal headache (26.3% migraine, 19.1% TTH).
• 23.7% had peri-ictal headache (6.7% pre-ictal, 19.1% post-ictal).
• Pre-ictal headache was linked to migraine; post-ictal headache associated with migraine, TTH, polytherapy, and seizure frequency.

Conclusions:

• Migraine is the most common headache in epilepsy patients.
• Migraineurs have higher risk for pre-ictal headaches.
• Patients with inter-ictal headaches are prone to post-ictal headaches.
