Association of Prenatal Exposure to Antiseizure Medications With Creative and Executive Function at Age 4.5 Years.

Background And Objectives: Neurodevelopmental effects of fetal antiseizure medication (ASM) exposure on creativity and executive functions are poorly understood. We previously found fetal valproate exposure to adversely affect measures of creativity and executive functions. In this study, we examine fetal exposure of newer ASMs on these functions in children of women with epilepsy (WWE) compared with children of healthy women (HW).

Behavioral Outcomes and Neurodevelopmental Disorders Among Children of Women With Epilepsy.

Importance: The association of fetal exposure to antiseizure medications (ASMs) with outcomes in childhood are not well delineated.

Objective: To examine the association of fetal ASM exposure with subsequent adaptive, behavioral or emotional, and neurodevelopmental disorder outcomes at 2, 3, and 4.5 years of age.

Two-Year-Old Cognitive Outcomes in Children of Pregnant Women With Epilepsy in the Maternal Outcomes and Neurodevelopmental Effects of Antiepileptic Drugs Study.

Importance: The neurodevelopmental risks of fetal exposure are uncertain for many antiseizure medications (ASMs).

Objective: To compare children at 2 years of age who were born to women with epilepsy (WWE) vs healthy women and assess the association of maximum ASM exposure in the third trimester and subsequent cognitive abilities among children of WWE.

Design, Setting, And Participants: The Maternal Outcomes and Neurodevelopmental Effects of Antiepileptic Drugs (MONEAD) study is a prospective, observational, multicenter investigation of pregnancy outcomes that enrolled women from December 19, 2012, to January 13, 2016, at 20 US epilepsy centers.

Folate fortification of food: Insufficient for women with epilepsy.

Objective: Folic acid supplementation during the periconceptual period has been shown to improve cognitive outcomes in children of women with epilepsy taking anti-seizure medications (ASMs). The dose of folic acid necessary to provide positive cognitive outcomes is unclear. In many countries including the United States, food is fortified with folic acid, but no data exist on how food fortification may affect cognition in children with fetal-ASM exposure.

Effects of periconceptional folate on cognition in children of women with epilepsy: NEAD study.

Objective: Emerging evidence suggests potential positive neuropsychological effects of periconceptional folate in both healthy children and children exposed in utero to antiseizure medications (ASMs). In this report, we test the hypothesis that periconceptional folate improves neurodevelopment in children of women with epilepsy by re-examining data from the Neurodevelopmental Effects of Antiepileptic Drugs (NEAD) study.

Methods: The NEAD study was an NIH-funded, prospective, observational, multicenter investigation of pregnancy outcomes in 311 children of 305 women with epilepsy treated with ASM monotherapy.

Are frontal and temporal lobe epilepsy dissociable in their memory functioning?

There is controversy in the literature as to how dissociable frontal lobe epilepsy (FLE) and temporal lobe epilepsy (TLE) are in terms of memory deficits. Some researchers have demonstrated that FLE is associated with greater executive dysfunction including working memory, whereas TLE is associated with greater memory impairment. Others have found the two groups to be comparable in memory functioning.

Fetal antiepileptic drug exposure and learning and memory functioning at 6 years of age: The NEAD prospective observational study.

The Neurodevelopmental Effects of Antiepileptic Drugs (NEAD) Study was a prospective observational multicenter study in the USA and UK, which enrolled pregnant women with epilepsy on antiepileptic drug (AED) monotherapy from 1999 to 2004. The study aimed to determine if differential long-term neurodevelopmental effects exist across four commonly used AEDs (carbamazepine, lamotrigine, phenytoin, and valproate). In this report, we examine fetal AED exposure effects on learning and memory functions in 221 six-year-old children (including four sets of twins) whose mothers took one of these AEDs during pregnancy.

Neurocognitive and behavioral profiles of children with Landau-Kleffner syndrome.

This is a retrospective study of 14 cases of children with Landau-Kleffner syndrome (LKS), the most prominent feature of which is acquired aphasia. These children were followed at a tertiary care pediatric epilepsy center. From the research data base, all LKS cases with neuropsychological evaluation were extracted.

[Formula: see text]Differences in memory functioning between children with attention-deficit/hyperactivity disorder and/or focal epilepsy.

Prior research has shown that attention-deficit/hyperactivity disorder (ADHD) and epilepsy are frequently comorbid and that both disorders are associated with various attention and memory problems. Nonetheless, limited research has been conducted comparing the two disorders in one sample to determine unique versus shared deficits. Hence, we investigated differences in working memory (WM) and short-term and delayed recall between children with ADHD, focal epilepsy of mixed foci, comorbid ADHD/epilepsy and controls.

IQ at 6 years after in utero exposure to antiepileptic drugs: a controlled cohort study.

Objective: To delineate the risk to child IQ associated with frequently prescribed antiepileptic drugs.

Methods: Children born to women with epilepsy (n = 243) and women without epilepsy (n = 287) were recruited during pregnancy and followed prospectively. Of these, 408 were blindly assessed at 6 years of age.

Executive Function Performance for Children With Epilepsy Localized to the Frontal or Temporal Lobes.

Research with adults with epilepsy consistently indicates deficits in executive function (EF). There is less research specific to children with epilepsy and EF. The purpose of this study was to consider EF deficits in children with complex partial epilepsy and complex partial with secondary generalization epilepsy with onset localized to the frontal or temporal lobes.

Spectrum of Mathematical Weaknesses: Related Neuropsychological Correlates.

Math disorders have been recognized for as long as language disorders yet have received far less research. Mathematics is a complex construct and its development may be dependent on multiple cognitive abilities. Several studies have shown that short-term memory, working memory, visuospatial skills, processing speed, and various language skills relate to and may facilitate math development and performance.

Breastfeeding in children of women taking antiepileptic drugs: cognitive outcomes at age 6 years.

Importance: Breastfeeding is known to have beneficial effects, but concern exists that breastfeeding during maternal antiepileptic drug (AED) therapy may be harmful. We previously noted no adverse effects of breastfeeding associated with AED use on IQ at age 3 years, but IQ at age 6 years is more predictive of school performance and adult abilities.

Objectives: To examine the effects of AED exposure via breastfeeding on cognitive functions at age 6 years.

Does Rey Complex Figure copy performance measure executive function in children?

The Rey Complex Figure Task (RCFT) is currently utilized with both adult and child clinical populations. In addition to the measurement of visual-constructional ability and memory, the RCFT has also been suggested as a measure of executive function (EF), specifically requiring planning and organizing skills. The purpose of the current study was to determine the extent to which the RCFT Copy task, using the scoring system developed by Meyers and Meyers (1995), tapped components of EF.

Fetal antiepileptic drug exposure and cognitive outcomes at age 6 years (NEAD study): a prospective observational study.

Background: Many women of childbearing potential take antiepileptic drugs, but the cognitive effects of fetal exposure are uncertain. We aimed to assess effects of commonly used antiepileptic drugs on cognitive outcomes in children up to 6 years of age.

Methods: In this prospective, observational, assessor-masked, multicentre study, we enrolled pregnant women with epilepsy on antiepileptic drug monotherapy (carbamazepine, lamotrigine, phenytoin, or valproate) between October, 1999, and February, 2004, at 25 epilepsy centres in the UK and the USA.

Posterior quadrant epilepsy surgery: predictors of outcome.

Purpose: To identify predictors of seizure recurrence following posterior quadrant epilepsy surgery.

Methods: Between 1983 and 2008, 43 medically refractory epilepsy patients underwent posterior quadrant epilepsy surgery. Epilepsy surgery involved the occipital lobe in all cases; some cases also included resection of the adjacent parietal or temporal cortex.

Fetal antiepileptic drug exposure: motor, adaptive, and emotional/behavioral functioning at age 3 years.

The Neurodevelopmental Effects of Antiepileptic Drugs (NEAD) Study is an ongoing prospective observational multicenter study in the United States and United Kingdom that enrolled pregnant women with epilepsy on antiepileptic drug (AED) monotherapy from 1999 to 2004. The study seeks to determine if differential long-term neurodevelopmental effects exist across four commonly used AEDs (carbamazepine, lamotrigine, phenytoin, valproate). In this article, we examine fetal AED exposure effects on motor, adaptive, and emotional/behavioral functioning in 229 children who completed at least one of these tests at 3 years of age.

Relationship of child IQ to parental IQ and education in children with fetal antiepileptic drug exposure.

Clinical trial designs need to control for genetic and environmental influences when examining cognitive outcomes in children for whom clinical considerations preclude randomization. However, the contributions of maternal and paternal IQ and education to pediatric cognitive outcomes are uncertain in disease populations. The Neurodevelopmental Effects of Antiepileptic Drugs (NEAD) Study is an ongoing prospective observational multicenter study in the United States and United Kingdom, which enrolled pregnant women with epilepsy to determine if differential long-term neurodevelopmental effects exist across four commonly used antiepileptic drugs.

Foetal antiepileptic drug exposure and verbal versus non-verbal abilities at three years of age.

We previously reported that foetal valproate exposure impairs intelligence quotient. In this follow-up investigation, we examined dose-related effects of foetal antiepileptic drug exposure on verbal and non-verbal cognitive measures. This investigation is an ongoing prospective observational multi-centre study in the USA and UK, which has enrolled pregnant females with epilepsy on monotherapy from 1999 to 2004.

Long-term neuropsychological follow-up of a child with Klüver-Bucy syndrome.

We describe the case of a 10-year-old girl who developed behavioral changes consistent with Klüver-Bucy Syndrome following Listeria meningoencephalitis at 2½ years of age. MRI at age 4 revealed evidence of diffuse brain atrophy with predominant temporal lobe involvement. Electroencephalograpy at 9½ years of age showed abnormal electrical discharges from the left temporal area.
