Abstract
Panic attacks, a frequent type of pseudoepileptic seizures, occur more frequently in epilepsy patients than in the general population and are often misdiagnosed, leading to pseudosevere epilepsy. We evaluated 4 patients with a past history of epileptic seizures long in remission who were misdiagnosed as having relapsing seizures although they had fairly typical panic attacks. To avoid unnecessary and ineffective antiepileptic drug (AED) treatment, recurrence of seizures after long remission should be carefully evaluated to identify patients with a panic disorder who require specific treatment. In patients who unexpectedly exhibit seizures after long remission, an accurate retrospective diagnosis of the epileptic syndrome and a precise description of the attack symptomatology should be obtained, if possible with EEG-video monitoring.
