Background Levetiracetam, a widely used antiepileptic drug in children, has been associated with psychosocial and behavioral problems, which are also influenced by epilepsy variables, including duration or seizure frequency. Purpose The objective of this study is to investigate the frequency and timing of treatment-emergent psychosocial and behavioral problems in children receiving levetiracetam, irrespective of seizure variables which are possible confounders. Methods A prospective, case–control study with a 3-month follow-up was conducted. Consecutive children aged 6 to 16 years with new-onset partial seizures were included in case of starting treatment with either levetiracetam or valproic acid. Psychosocial and behavioral functioning were assessed using a set of standardized questionnaires including Strengths and Difficulties Questionnaire (SDQ) and Children's Depression Inventory (CDI) at baseline, 1 and 3-month follow-up. Patients' baseline scores were compared to healthy subjects. The difference in the follow-up SDQ and CDI scores was evaluated in patients receiving levetiracetam and valproic acid. Results A total of 101 participants were analyzed; 32 patients in levetiracetam group, 19 patients in valproic acid group and 50 healthy controls. Baseline SDQ and CDI scores were not statistically different between patients and healthy subjects ( p > 0.05). No statistically significant difference was observed in CDI, total and subscale SDQ scores between patients receiving levetiracetam or valproic acid during the study period ( p > 0.05). A girl aged 15 years receiving levetiracetam had a CDI score of 18 without suicidal ideation at baseline. She developed suicidal ideation and depression, which resolved after switching of levetiracetam to valproic acid, at the 1-month follow-up. No other psychiatric or behavioral side-effects were observed in other patients. Conclusion Psychosocial and behavioral side-effects of levetiracetam treatment are not frequent and they don't emerge in most of children at lower doses. At this dose, and after 3 months, using these specific instruments, we did not observe any difference between the valproic acid and levetiracetam treatment groups.

This prospective study aimed to evaluate long-term neurodevelopmental outcomes and risk factors of the previously reported cohort, at their school age.We included neonates whose seizures were directly observed by the child neurologist or neonatologist based on clinical observations. They were assessed for cognitive and neurological outcomes at the age of 9-11 years. The test battery included a neurological examination, the Wechsler Intelligence Scale for Children-Revised (WISC-R) test, and patients with the diagnosis of cerebral palsy (CP) were graded according to the Gross Motor Function Classification System (GMFCS). The primary outcome of this study was to determine risk factors for the long-term prognosis of neonatal seizures.For the long-term follow-up, 97 out of 112 patients of the initial cohort were available (86.6%). We found that 40 patients (41%) have the normal prognosis, 22 patients (22.7%) have the diagnosis of CP, and 30 patients (30.9%) were diagnosed as having epilepsy. Twelve out of 22 patients with CP had the diagnosis of epilepsy. The WISC-R full-scale IQ scores were55 points in 27 patients (27.8%) and were85 points in 40 patients (41.2%). According to GMFCS, 10 patients were classified as levels 1-2, and 12 patients were classified as levels 3-5. In multivariate regression analyses, 5-min APGAR score6 was found to be an independent risk factor for CP, and 5-min APGAR score6 and neonatal status epilepticus were independent risk factors for epilepsy.This prospective cohort study reveals that abnormal school age outcome after neonatal seizures are significantly related to 5-min APGAR score6 and neonatal status epilepticus.
