Staring Spells: How to Distinguish Epileptic Seizures from Nonepileptic Staring.

In children presenting with staring spells, the differential diagnosis of epileptic staring spells vs nonepileptic staring spells can be made by history and routine EEG. Staring was as likely to be epileptic as nonepileptic spells. Younger children with developmental delay were more likely to have nonepileptic events. Our simple approach based on event duration, postictal symptoms, and EEG allowed identification of epileptic staring on first visit to new-onset seizure clinic but requires validation in future prospective studies including long-term video EEG monitoring and follow-up.
