Abstrakt: Objective: The aim of this study is to describe the pre‐ and post‐operative developmental and intellectual functions in a cohort of patients who underwent surgery for drug‐resistant epilepsy (DRE) before the age of 5 years. Method: We retrospectively reviewed the medical records and neurodevelopmental assessments of a cohort of 80 surgically treated pediatric patients with DRE. We included patients if they had at least one pre‐ and one post‐surgical neuropsychological assessments; 27 met the inclusion criteria. We evaluated Developmental Quotient (DQ) and Intelligence Quotient (IQ) before and after surgery. We identified two groups based on psychological evaluation outcome: Group 1, with stable or improved developmental and intellectual functions, and Group 2, experiencing developmental and intellectual loss. Results: The mean age at seizure onset was 1.2 ± 1.0 years, and the mean age at surgery was 2.9 ± 1.2 years. At the last follow‐up (mean 4 years, SD ± 2), 19/27 (70%) patients were seizure‐ and drug‐free; 18/27 patients (67%) fit in Group 1, and 9/27 (33%) fit in Group 2. The mean age at surgery was 2.6 years (SD ± 1.1; range 1.2–5.1) in Group 1 and 3.4 years in Group 2 (SD ± 1.1; range 1.6–5.0). Group 1 had a lower pre‐operative DQ/IQ total score than Group 2 (median DQ/IQ respectively 82 vs 108, p = 0.05). Between pre‐ and post‐assessments, we found that in Group 1, Performance scores improved (82.7 vs 102, p = 0.001), while in Group 2, the Total and Verbal scores worsened (respectively 108 vs 75, p = 0.008, and 100 vs 76, p = 0.021). Significance: Our study's results emphasize the positive impact of surgery before the age of 5 years on developmental and intellectual outcomes. Despite limitations such as a small sample size, lack of a control group, and diverse etiologies, our findings support the crucial role of early intervention in preserving or enhancing developmental and intellectual functions in young patients with DRE. Plain Language Summary: This retrospective study, conducted at the Bambino Gesù Children Hospital in Italy, reports neuropsychological and developmental and/or cognitive data for children undergoing early epilepsy surgery (before the age of 5). It found that children with lower developmental or cognitive profiles gained the highest scores on post‐operative neuropsychological evaluations. This study provides information on the potential benefits of early surgery in shortening the duration of epilepsy, preventing or arresting deterioration, and enhancing plasticity and recovery.
