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…

Background: Various psychiatric and neurological disorders including epilepsy have been associated with language deficits. Pragmatic language deficits, however, have seldom been the focus of earlier studies in children with epilepsy. Moreover, it is unknown whether these pragmatic deficits are related to general intellectual functioning. Both…

Aim: Epilepsy is associated with difficulties in cognition and behavior in children. These problems have been attributed to genetics, ongoing seizures, psychosocial issues, underlying abnormality of the brain, and/or antiepileptic drugs. In a previous study, we found baseline cognitive differences between children with partial versus generalized…

The offspring of mothers with epilepsy are considered to be at developmental risk during pregnancy from: (1) generalized maternal seizures (hypoxia); (2) teratogenicity of antiepileptic drugs (AEDs); and (3) adverse socio-familial conditions associated with having a chronically sick mother. Sixty-seven children of mothers with epilepsy and 49…

This study assessed rates of learning disabilities (LD) by several psychometric definitions in children with epilepsy and identified risk factors. Participants (N = 173, ages 8-15 years) completed IQ screening, academic achievement testing, and structured interviews. Children with significant head injury, chronic physical conditions, or mental…

We studied expressive and receptive language, oral motor ability, attention, memory, and intelligence in 20 6-year-old children with epilepsy (14 females, six males; mean age 6y 5mo, range 6y-6y 11mo) without learning disability, cerebral palsy (CP), and/or autism, and in 30 reference children without epilepsy (18 females, 12 males; mean age 6y…

This study, involving 90 children with mental retardation and epilepsy, classified and compared level of retardation, neurological findings, and electroencephalograms with the quality of seizure control. No correlation was found between quality of control and any of these parameters. (Author/JDD)
