The intellectual profile of pediatric patients with posterior cortex epilepsy

•There is no impact of the epileptogenic zone on IQ among children with epilepsy.•Working memory and processing speed are impaired in posterior cortex epilepsy.•Cognitive dysfunction in posterior cortex is similar to frontal lobe epilepsy. Cognitive functioning in epileptic syndromes has been widely explored in patients with temporal lobe epilepsy (TLE), but few studies have investigated the neuropsychological profile in posterior cortex epilepsy (PCE). In this study, we investigated the presurgical intellectual profile of children and adolescents with drug-resistant PCE. Children and adolescents diagnosed with PCE (n = 25) participated in this study. The data were obtained from medical records, with assessments carried out between the years 2003 and 2019. To compare the intellectual profile, we also included patients diagnosed with frontal (n = 26) and temporal lobe epilepsy (n = 40). The Wechsler Intelligence Scales were used for the assessment of general intelligence. There was an effect of the brain region on the Working Memory Index (p
