All mentally retarded (MR) subjects in a northern Swedish county were assessed for the occurrence of active epilepsy on a prevalence day. Active epilepsy was found in 299 subjects (20.2% of those with MR) corresponding to a crude prevalence rate of 1.2/1000 inhabitants. The age-specific prevalence for 0-9 years was higher for females than for males, while… (More)
CSF-hydrodynamic investigation using the constant pressure infusion method was used in children. The CSF resting pressure was recorded and the CSF formation rate was measured. The conductance of the CSF outflow pathways and the pressure in the sagittal sinus were calculated. The method was used in children with suspicion of disturbed CSF hydrodynamics due… (More)
In a prospective community-based study of 103 children with febrile convulsions (FC), social and genetical factors were compared with 193 age and sex matched referents sampled from the community. FC were found more often among parents of cases than referents (odds ratio 21.0; p less than 0.001). A history of FC in any type of relative was found in 39.8% of… (More)
Eleven children with typical absence seizures were studied clinically and by repeated 24-h EEGs with portable cassette tape recorder before and during anticonvulsant treatment. The history, the observation of seizures and the amount of spike-and-wave activity (episodes greater than 3 sec) were studied in relation to the plasma levels. The EEG revealed… (More)
Literature concerning the role of the Child Health Services in the identification of children with possible Attention Deficit Hyperactivity Disorder/Deficits in Attention, Motor Control and Perception (ADHD/DAMP) is summarized in order to establish a background for evaluation, discussion and conclusion.
A modified low phenylalanine diet was instituted in an 8-year-old PKU boy earlier untreated and mentally retarded. The boy was treated during a ten year observation period. A marked progress in mental capacity and in IQ scoring was seen. The difficulties in objective evaluation of the benefit of late introduced treatment with a diet low in phenylalanine is… (More)
In an epidemiological investigtion of mental retardation in the county of Västerbotten in Sweden the mother of five severely mentally retarded children was found to have untreated phenylketonuria (PKU). None of the children had PKU. The maternal PKU may have been a cause of the mental retardation, retarded intrauterine growth and different types of… (More)
