Seizure recurrence following the first unprovoked seizure: Risk factors among children in UAE

Area of Science:

• Neurology
• Pediatrics
• Epileptology

Background:

• First unprovoked seizures in pediatric and adolescent populations require understanding recurrence patterns.
• Identifying predictors of seizure recurrence is crucial for effective patient management and prognosis.

Purpose of the Study:

• To identify significant risk factors associated with seizure recurrence in pediatric and adolescent patients in Abu Dhabi, UAE.
• To analyze the timing and overall risk of seizure recurrence after a first unprovoked seizure.

Main Methods:

• Retrospective study of 317 pediatric and adolescent patients with a first unprovoked seizure (March 2016 - March 2020).
• Minimum one-year follow-up data collected to assess seizure recurrence.
• Analysis of clinical factors, electroencephalogram (EEG), and magnetic resonance imaging (MRI) findings.

Main Results:

• A high recurrence rate of 96.2% was observed, with 68.8% occurring within the first 6 months.
• Significant risk factors for recurrence included focal seizures, symptomatic etiology, abnormal initial EEG, abnormal MRI, and co-existing neurological disorders.
• The type of epileptiform activity on initial EEG did not predict recurrence. Overall 3-year recurrence risk reached 98.4%.

Conclusions:

• Vigilant monitoring is essential, particularly in the early post-seizure period for pediatric and adolescent patients.
• Initial EEG and MRI assessments are recommended, especially for remote symptomatic first unprovoked seizures.
• Understanding recurrence patterns aids in optimizing management strategies for young epilepsy patients.
