Peri-ictal headaches in the paediatric population - prospective study.

The co-occurrence of headache and epilepsy is well-documented in the adult population. The aim of the prospective study was to analyse in the paediatric population the correlations between the types of peri-ictal headaches and types of seizures. Furthermore, an attempt was made to find trends in characteristic features of peri-ictal headaches. A total of 913 seizure and 325 peri-ictal headache episodes were noted during the study. Post-ictal headaches were most common, occurring in < 1 h after the seizure, lasting minutes to hours and more likely to occur after generalised seizures, whereas pre-ictal headaches occurred 30-240 min before the seizure. In the analysed group, peri-ictal headaches were most often moderate in intensity. Only 30% of patients took analgesic medication, usually to treat post-ictal headaches. Peri-ictal headaches are a significant health problem for patients with epilepsy. The most common type are post-ictal headaches, and they are most likely to appear after a generalised seizure.
