Description
Summary:Many studies of selected groups of children with epilepsy have demonstrated an association between epilepsy and cognitive deficits. The aim of this study was to assess the intellectual skills of children with epilepsy and to investigate the influence of gender, age at seizure onset, type of epilepsy, antiepileptic drug used, and control of epilepsy on their intellectual function. This is a descriptive prospective study in which one hundred and eighty-seven patients at school age (6–14 years) were recruited. Epilepsy was classified using the International League Against Epilepsy (ILAE) Commission on Classification and Terminology 2005–2009 report. An intelligence quotient (IQ) test was conducted to all patients using Stanford–Binet Fifth Edition (SB5)/Arabic version. Eighty-eight (47.1%) patients had an average score on Full Scale IQ (FSIQ), 44 (23.5%) had low average, whereas 18 (9.6%) had borderline impaired or delayed score. In the nonverbal IQ (NVIQ) score, the majority 84 (44.9%) had average score. The performance of the patients in the nonverbal score is better than in the verbal score, which was found to be statistically significant (P-value = 0.01). The FSIQ score was negatively affected by younger age at onset of epilepsy, polytherapy, and uncontrolled seizures. Most of children with epilepsy had an average FSIQ; uncontrolled seizure had worse effect on overall FSIQ and memory. Interventions to support children with epilepsy should focus on epilepsy management and school psychosocial domains. •47.1% patients had average score on FSIQ.•Patients' scores on NVIQ are better than on VIQ.•FSIQ score was affected by age at onset of epilepsy, polytherapy and uncontrolled seizures.
