OBJECTIVE To investigate the effect of antiepileptic drugs, especially carbamazepine and valproate, on intelligence in prenatally exposed children of mothers with epilepsy. METHODS Intelligence of 182 children of mothers with epilepsy (study group) and 141 control children was tested in a blinded setting at preschool or school age using Wechsler Preschool(More)
OBJECTIVE To evaluate the occurrence and prognostic importance of focal defects in cerebral cortical glucose metabolism in infants with newly diagnosed symptomatic and cryptogenic infantile spasms. PATIENTS AND METHODS Ten children with symptomatic and seven with cryptogenic infantile spasms underwent MRI, video-EEG, and PET using fluorodeoxyglucose as a(More)
Invasive cortical mapping is conventionally required for preoperative identification of epileptogenic and eloquent cortical regions before epilepsy surgery. The decision on the extent and exact location of the resection is always demanding and multimodal approach is desired for added certainty. The present study describes two non-invasive preoperative(More)
Mutations in the cyclin-dependent kinase-like 5 gene (CDKL5) have been identified in female patients with early onset epileptic encephalopathy and severe mental retardation with a Rett-like phenotype. Subsequently CDKL5 mutations were shown to be associated with more diverse phenotypes including mild epilepsy and autism without epilepsy. Furthermore, CDKL5(More)
PURPOSE Proton magnetic resonance spectroscopic imaging (1H MRSI) can lateralize the epileptogenic frontal lobe by detecting metabolic ratio abnormalities in frontal lobe epilepsy (FLE). We used 1H MRS to lateralize and localize the epileptogenic focus, and we also sought to characterize further the metabolic abnormality in FLE. METHODS We measured(More)
PURPOSE To investigate the value of interictal magnetoencephalography (MEG) in localizing epileptogenic cortex in epilepsy surgery patients with focal cortical dysplasias (FCD), particularly in patients having no visible MRI lesions. METHODS Thirty-four patients with FCD and preoperative MEG were retrospectively evaluated. Interictal MEG spike source(More)
The risk of psychomotor retardation and the prevalence of mental subnormality are slightly increased in offspring of mothers with epilepsy. The prevalence rates of mental deficiency observed in population-based studies have been lower than those in reports of hospital-based studies. In addition to use of antiepileptic drugs (AEDs), several other factors(More)
Research findings concerning cognitive effects of pediatric epilepsy surgery form an important basis for decisions about surgery. However, most follow-up studies have been of limited duration. In this study, a 2-year follow-up of intelligence was undertaken. Risk factors were analyzed. Included were 38 patients aged 3 to 17 years. Surgery was left in 19(More)
Specific cognitive abilities and motor function were investigated at 5.5 years in 104 children with epileptic mothers and in 105 control children, all with normal general intelligence. The majority (89 per cent) of the children of epileptic mothers had been exposed to anti-epileptic drugs during pregnancy, most commonly phenytoin (69 per cent). Maternal(More)
The purpose of this study was to investigate early electroclinical manifestations and evaluate treatment responses by video-EEG in infants with newly diagnosed spasms. Spasms were recorded in 44 infants (27 males, 17 females) before adequate treatment. Mean ages at onset of spasms and at first video-EEG were 5.3 months (range 0.9 to 9 months) and 5.9 months(More)
