OBJECTIVE To determine the prevalence rates of child psychiatric diagnoses in a school-based population of children aged 6 to 8 years in the south of the province of Limburg (The Netherlands). METHOD In a two-stage design 1,317 children were screened with the Child Behavior Checklist. From 403 of these children, child psychiatric information was obtained(More)

METHOD By screening a general population sample of 1317 five- to six-year-old children, four groups of children were selected. The performance of 30 children later diagnosed with ADHD(More)
Clumsiness in preschool children may be a precursor to impaired academic performance and psychological and developmental problems. It is assumed that in this age group especially the qualitative aspects (=pattern) of a movement reflect variations in motor development. Currently available motor tests for this age group, however, mostly objectify quantitative(More)
In this review we systematically assess our current knowledge about psychogenic non-epileptic seizures (PNES), epidemiology, etiology, with an emphasis on the diagnostic issues. Relevant studies were identified by searching the electronic databases. Case reports were not considered. Articles were included when published after 1980 up till 2005 (26 years). A(More)
Adults suffering from Attention Deficit Hyperactivity Disorder (ADHD) are known to have disturbed central dopaminergic transmission. With Single Photon Emission Computed Tomography (SPECT) we studied brain dopamine transporter and receptor activity in six boys with ADHD.

Of the 351 males with Duchenne muscular dystrophy, 11.7% were reported to have a comorbid diagnosis of(More)

Aim of the present study was two fold: (1) to evaluate the course of referring and diagnosing Learning Disabilities (LD) and the contribution of multidisciplinary assessment and (2) to describe characteristics of three LD subtypes: Attention with or without Motor function Disabilities (AMD), Verbal Learning Disabilities (VLD) and Non-Verbal Learning(More)
The aim of this prospective study was to examine whether neurocognitive performance of children aged 5-6 years distinguished children who were later diagnosed with attention deficit/hyperactivity disorder(ADHD) or "borderline ADHD" from children without ADHD after adjustment for behavioral measures and to examine the influence of comorbid psychopathology.(More)
