Summary

Think of seizure mimics before you diagnose epileptic seizures. Some mimics such as syncope, transient ischemic attacks (TIA), and migraines may be associated with EEG abnormalities. Seizure mimics may be neurological, systemic, or psychological. Always confirm if the event in question is consistent with the patient’s typical event as the patient may have more than one type of event. Though uncommon, both epileptic and nonepileptic events may coexist; hence it is important to characterize each of the patient’s event types on video EEG.
