Background: Epilepsy in children is a commonly diagnosed phenomena and the requirement of accurate diagnosis and treatment seek great attention in recent research. The correlation between cognitive impairment and other factors such as ongoing seizures, antiepileptic syndrome, high seizure frequency, and the consequences of poly-medication has to be revealed. Aim: To evaluate the intellectual functioning in the children affected with epilepsy and thereby assess the impact of epilepsy-associated variables on their IQ score. Methods: A prospective study is conducted with 104 children in Baghdad in 2017. The study recorded clinical parameters like seizure types, the onset of a seizure, and details of antiepileptic drugs by Raven score. Result: The prevalence of sub-normal IQ was observed to be 39.4% and the mean IQ level was 75.5%. Likewise, early-onset children had the lowest IQ level (64%) than late-onset children and 65.1% of symptomatic type with low mean IQ is observed when compared with the localized and idiopathic type. A high prevalence of mental retardation is found with mixed type of seizures and accordingly, the population with poor seizure control possess the lowest IQ (66%) than partial seizure control. Mental retardation prevalence was found to be 92%, 39.4%, and 10.9% in children with poor, partial, and good seizure control. Conclusion: The study concluded that Childhood-onset epilepsy is considered a major risk factor for low IQ levels. Furthermore, the lowest IQ level is found under the following conditions such as earlyonset, mixed type, symptomatic epilepsy, poor seizure control, and multiple drug therapy.
