Summary
Seizure-associated headache (SH) is a frequent and severe symptom in epilepsy patients, often presenting as migraine-like. A history of migraine significantly increases the likelihood of experiencing SH.
Area of Science:
- Neurology
- Epileptology
- Headache Medicine
Background:
- Headache is an underrecognized symptom of epileptic seizures.
- Understanding seizure-associated headache (SH) is crucial for comprehensive epilepsy management.
Purpose of the Study:
- To investigate the frequency, classification, and characteristics of seizure-associated headache (SH).
- To analyze SH in epilepsy patients according to International Headache Society criteria.
Main Methods:
- Prospective study of 341 epilepsy patients evaluated for SH over 15 months.
- Standardized questionnaire used to collect data on headache characteristics and timing relative to seizures.
Main Results:
- 34% of epilepsy patients experienced SH, with significant pain intensity and duration.
- SH predominantly occurred postictally (70%) and was often classified as migraine headache (55.7%).
- A history of migraine was strongly associated with migraine-like SH.
Conclusions:
- Seizure-associated headache is a frequent, severe, and debilitating symptom in epilepsy.
- Migraine history is a significant risk factor for developing migraine-like SH.
- Recognizing and managing SH is essential for improving the quality of life in epilepsy patients.
