Neurobehavioral abnormalities may correlate with increased seizure burden in children with Panayiotopoulos syndrome

Area of Science:

• Neurology
• Pediatric Epilepsy

Background:

• Panayiotopoulos syndrome is a common childhood epilepsy syndrome.
• Understanding prognostic factors is crucial for patient management.

Purpose of the Study:

• To identify prognostic factors associated with frequent seizure recurrences in Panayiotopoulos syndrome.
• To investigate the role of neurobehavioral disorders in seizure frequency and treatment response.

Main Methods:

• Retrospective analysis of medical records and electroencephalograms of 79 children with Panayiotopoulos syndrome.
• Classification of patients into typical, borderline, and atypical groups based on seizure recurrence frequency.
• Analysis of various clinical and demographic factors, including neurobehavioral disorders.

Main Results:

• A significant association was found between pre-existing neurobehavioral disorders and a higher frequency of seizures (>10 times) in the atypical group.
• Patients with Panayiotopoulos syndrome and mild neurobehavioral disorders exhibited pharmacoresistant seizures that recurred frequently.
• All patients achieved seizure remission by 12 years of age.

Conclusions:

• Pre-existing neurobehavioral disorders are a significant prognostic factor for frequent, pharmacoresistant seizures in Panayiotopoulos syndrome.
• Despite potential for frequent recurrences, Panayiotopoulos syndrome generally has a favorable long-term prognosis with seizure remission by adolescence.
• Surgical evaluation is typically not indicated for patients with Panayiotopoulos syndrome.
