Objective: It has been suggested that both low iron and zinc levels might be associated with Attention Deficit Hyperactivity Disorder (ADHD) symptoms. However, the association of zinc and iron levels with ADHD symptoms has not been investigated at the same time in a single sample. Method: 118 subjects with ADHD (age = 7-14 years, mean = 9.8,…

The importance of well-specified research questions in the evaluation of early predictors of later inattention and hyperactivity is examined. In an analysis of a nationally representative sample of 2,717 children aged 4 to 10, latent growth trajectories for television viewing and inattention and hyperactivity are determined and the relationship of…

The aim was to examine the rates and types of parent reported neuropsychiatric problems in children and adolescents with mild mental retardation (MMR) (mild intellectual disability/UK) using the Five-To-Fifteen questionnaire (FTF).

Objective: To compare the ADHD combined/hyperactive subtype (ADHD/CH) to the ADHD inattentive subtype (ADHD/I) on the level of comorbidity, treatment response, and possible etiological factors. Method: A total of 371 clinically referred children diagnosed with ADHD aged between 6 and 12 years are recruited for a double-blind, placebo-controlled…

For clinically referred children with Autism Spectrum Disorder (ASD) or Attention Deficit/Hyperactivity Disorder (ADHD) several early indicators have been described. However, knowledge is lacking on early markers of less severe variants of ASD and ADHD from the general population. The aim of the present study is to identify early indicators of…

Behavior and emotional problems are often present in very young children with autism spectrum disorders (ASDs) but their nosology has been the object of scant empirical attention. The objective of this study was to assess the construct validity of select "Diagnostic and Statistical Manual of Mental Disorders" ("DSM)"--defined…

Objective: We used multi-level modelling of sibling-pair data to disentangle the influence of proband-specific and more general family influences on maternal expressed emotion (MEE) toward children and adolescents with attention-deficit/hyperactivity disorder (ADHD). Method: MEE was measured using the Five Minute Speech Sample (FMSS) for 60…
