Article: Psychiatric disorders and MND in non-handicapped preterm children
[show abstract] [hide abstract]
ABSTRACT: In preterm children (N=66) without major physical and/ or mental handicaps the prevalence of psychiatric disorders and minor neurological dysfunction (MND) was assessed at school age (8–10years). In adolescence (15–17years) 43 children were reassessed. The study sample was drawn from a cohort of non-handicapped preterm children (N=218) hospitalised in a Neonatal Intensive Care Unit because of serious neonatal complications. The findings in the preterm group were compared with two control groups (N=20 and N=20) matched for age and sex ratio. The association between psychiatric disorders on the one hand and group status (preterm versus control), MND, IQ and family adversity on the other was explored. At both ages the preterm children exhibited more psychiatric disorders and MND than controls. The very preterm and/or very low birth weight children contributed to the differential psychopathological findings between the preterm and control groups. Besides preterm birth, the prevalence of psychiatric disorders was positively associated with MND and negatively associated with VIQ and family adversity. In the preterm group there was a shift from school age into adolescence into a predominance of anxious and depressive disorders. No significant changes with age were found with respect to the prevalence of MND and psychiatric disorders. Thus, very preterm and/or very low birth weight children are at increased risk of persistent psychiatric disorders, especially anxious and depressive disorders. In preterm children the development of psychopathology seems to be mediated by MND, decreased verbal abilities and family adversity.European Child & Adolescent Psychiatry 04/2012; 16(7):439-448. · 2.82 Impact Factor -

Article: Visual sustained attention in a child psychiatric population.
[show abstract] [hide abstract]
ABSTRACT: To increase knowledge of the diversity and specificity of sustained attention deficits in children with attention-deficit hyperactivity disorder (ADHD), with special reference to the issue of distinguishing between children with ADHD and children with other psychiatric diagnoses. A visual sustained attention task was used to compare 52 boys with ADHD with 55 normal controls, 29 boys with oppositional defiant disorder or conduct disorder (ODD/CD), 29 boys with anxiety or dysthymia (ANX/DYS), 43 boys with pervasive developmental disorder, 24 boys with ADHD plus ODD/CD, and 14 boys with ADHD plus ANX/DYS. Compared with normal controls, children with ADHD were slower, were more inaccurate, were more impulsive, were less responsive to feedback, and showed less perceptual sensitivity and stability of performance, resulting in a marked decrease in vigilance over time. Unresponsiveness to feedback and the extent of the decrease in vigilance during time on task were found to be the only factors that distinguished children with ADHD from children with other diagnoses. Although only children with ADHD are characterized primarily by "attention deficit," sustained attention deficit is common to a certain extent to all children with psychiatric disorders.Journal of the American Academy of Child & Adolescent Psychiatry 06/2000; 39(5):651-9. · 6.44 Impact Factor -
Article: Verbal memory and Performance IQ predict theory of mind and emotion recognition ability in children with autistic spectrum disorders and in psychiatric control children.
[show abstract] [hide abstract]
ABSTRACT: This study was designed to examine the developmental and cognitive correlates of theory of mind (ToM) and emotion recognition ability in children with autism (N = 20), with pervasive developmental disorder-not otherwise specified (PDD-NOS) (N = 20), and in psychiatric control children (N = 20). The diagnostic groups were person-to-person matched on age and verbal IQ. The age of the children was between 8 and 18 years; their Full Scale IQ was at least 65. The test battery included tasks for the matching and the context recognition of emotional expressions, and a set of first- and second-order ToM tasks. The relationships between composite domain scores and the subjects' age, Verbal IQ, Performance IQ, verbal memory, visual memory, and gender were examined in bivariate and multivariate analyses. Further, the subjects who reliably and consistently passed the tasks of a domain and those who could not were compared on developmental and cognitive characteristics. Overall, the results of the various analyses converged and indicated that verbal memory, Performance IQ, age and gender were the best predictors of social cognitive ability.Journal of Child Psychology and Psychiatry 10/1999; 40(6):869-81. · 4.28 Impact Factor -
Article: Theory of mind and emotion-recognition functioning in autistic spectrum disorders and in psychiatric control and normal children.
[show abstract] [hide abstract]
ABSTRACT: The hypothesis was tested that weak theory of mind (ToM) and/or emotion recognition (ER) abilities are specific to subjects with autism. Differences in ToM and ER performance were examined between autistic (n = 20), pervasive developmental disorder-not otherwise specified (PDD-NOS) (n = 20), psychiatric control (n = 20), and normal children (n = 20). The clinical groups were matched person-to-person on age and verbal IQ. We used tasks for the matching and the context recognition of emotional expressions, and a set of first- and second-order ToM tasks. Autistic and PDD-NOS children could not be significantly differentiated from each other, nor could they be differentiated from the psychiatric controls with a diagnosis of ADHD (n = 9). The psychiatric controls with conduct disorder or dysthymia performed about as well as normal children. The variance in second-order ToM performance contributed most to differences between diagnostic groups.Development and Psychopathology 02/1999; 11(1):39-58. · 4.40 Impact Factor
