There are different possible temporal associations between epileptic seizures and headache attacks which have given rise to unclear or controversial terminologies. The classification of the International League Against Epilepsy does not refer to this type of disorder, while the International Classification of Headache Disorders (ICHD-2) defines three kinds of association: (1) migraine-triggered seizure ("migralepsy"), (2) hemicrania epileptica, and (3) post-ictal headache. ⋯ On the basis of this review we suggest definitions and a terminology which may become the basis of a forthcoming classification of headaches associated with epileptic seizures.

Emergent electroencephalograms (EmEEG) are performed to exclude non-convulsive status epilepticus (NCSE) but are resource-intensive. Prior studies have identified a seizure or seizures in the acute setting preceding the EmEEG request as a risk factor of NCSE but few other consistent clinical risk factors have been identified. We aimed to identify clinical risk factors for NCSE in EmEEGs ⋯ Seizures in the acute setting, ocular movements and ongoing CNS infection are associated with NCSE. By using these risk factors at the bedside, clinicians can prioritize patients for EmEEG, recognizing that risk of NCSE increases as more clinical risk factors are present.

To evaluate amplitude-integrated EEG (aEEG) in comparison with conventional (cEEG) for the identification of electrographic seizures in neonates with acute neonatal encephalopathies. ⋯ In our study the observers identified SE in 100% of the reviewed traces using raw aEEG alone, thus aEEG might represent a useful tool to detect SE in the setting of NICU. SS may not be reliably identified using aEEG alone. Simultaneous recording of the raw cEEG/aEEG provides a good level of sensitivity for the detection of neonatal electrographic seizures.
