Parametric control of fingertip forces during precision grip lifts in children with DCD (developmental coordination disorder) and DAMP (deficits in attention motor control and perception).
Twenty boys with developmental coordination disorder (DCD), 11 of whom had associated attention deficit disorder (ADD), were compared with an age-matched control group of 12 boys to examine mechanisms that adapt the grip force at the digit-object interface in a precision grip task. An experimental grip object equipped with pressure transducers registered the grip forces (normal to the surface) and the load force (tangential to the surface) generated by the fingertips. The surface of the object was changed to vary the frictional properties. Both study groups exhibited disturbances of the basic coordination of forces in the initial phase of the movement, manifested by longer time latencies and higher force levels than the control group. All subjects were able to adapt the force output in response to the friction at the digit-object interface. Higher grip forces and safety margins were documented for the DCD group in comparison to the controls. Furthermore, there was greater variation in the parametric control of the grip force in the DCD group. The results suggest that the control of the grip force is similar in children with DCD, regardless of whether they have associated ADD or not, but it is impaired in comparison to that of controls.

Regional cerebral blood flow in weight-restored anorexia nervosa: a preliminary study.
Twenty-one individuals (19 females, two males) with teenage-onset anorexia nervosa (AN), 19 of whom were weight restored, were assessed using single-photon emission computed tomography (SPECT) 7 years after onset of AN, at a mean age of 22 years. For comparison we recruited a younger group without neuropsychiatric disorder (mean age 9:8 years; five females, four males) who underwent SPECT at follow-up after an operation for coarctation of the aorta or because of lymphatic leukaemia. Ethical considerations precluded the study of regional cerebral blood flow (rCBF) in participants with completely normal development. The group with AN showed marked hypoperfusion of temporal, parietal, occipital, and orbitofrontal lobes compared to the contrast group. rCBF was not correlated to body mass index in any of the groups. Results suggest that, even long after re-feeding has occurred, AN may be associated with moderate to severe cerebral blood flow hypoperfusion in the temporoparietal (or temporoparietooccipital) region and in the orbitofrontal region. A limitation of the study is that the young contrast group in this study could be expected to have a higher global rCBF than the group with AN. However, this should not significantly affect the relative values used in this study.

Autistic spectrum disorders in Möbius sequence: a comprehensive study of 25 individuals.
The prevalence of autistic disorder was analysed in 25 individuals with Möbius sequence, a disorder with brain-stem dysfunction. The sample consisted of 18 males and seven females (20 participants were aged 2 to 22 years, and five were aged 1, 19 and 23 months, and 55 years old). Participants were recruited after a nationwide call and were part of a multidisciplinary study of individuals with Möbius sequence. They were given a meticulous neuropsychiatric examination including standardized autism diagnostic interviews. Ten individuals had an autistic spectrum disorder. Six of these met all diagnostic criteria for autism. In 23 individuals cognitive development could be assessed. Eight of those 23 patients had clear learning disability and six individuals were functioning in the normal but subaverage range. Autistic spectrum disorder and learning disability occurred in more than a third of the examined patients. Considering the hospital-based nature of the sample, these findings may be overestimates. Nevertheless, awareness of this coexistence is important in the diagnosis and habilitation care of children with Möbius sequence. Moreover, the results provide further support for the notion of a subgroup of autistic spectrum disorders being caused by first trimester brain-stem damage.

Autistic disorders in Down syndrome: background factors and clinical correlates.
A study of a clinic-based sample of 25 individuals (12 females, 13 males; age at diagnosis 14.4 years, SD 7.4 years; age range 4 to 33 years) with Down syndrome (DS) and autism spectrum disorders, demonstrates that autism is by no means rare in DS. Results showed that there was a considerable delay in the diagnosis of autism as compared with children with autism who did not have DS. In 11 participants medical factors were identified that were likely to be of importance in contributing to the development of autism, and in four further participants there were factors of possible significance. Such factors include a history of autism or autism-related disorders in first- or second-degree relatives (n=5), infantile spasms (n=5), early hypothyroidism (n=3), evidence of brain injury after complicated heart surgery (n=2), or a combination of these factors. It is important that autism is recognised, identified, and fully assessed in individuals with DS in order for them to receive appropriate education and support.

A preliminary population-based twin study of self-reported eating disorder.
BACKGROUND: Twin studies have concluded that there is a substantial genetic contribution to the aetiology of eating disorders. The aim of the present study was to estimate the genetic contribution to the aetiology of self-reported eating disorders in a sample of representative twins. METHOD: A population cohort of 34142 young Danish twins was screened for eating disorders by a mailed questionnaire. RESULTS: Concordance rates differed significantly across monozygotic and dizygotic twin pairs for broadly defined self-reported anorexia nervosa and bulimia nervosa. Heritability estimates of 0.48, 0.52 and 0.61 respectively were estimated for narrow and broad definitions of self-reported anorexia nervosa and for self-reported bulimia nervosa. CONCLUSIONS: There is a genetic contribution to the aetiology of self-reported eating disorders in the general population. The relationship between self-reported and clinical eating disorder remains to be examined.

Screening for autism spectrum disorders in adult psychiatric out-patients: a preliminary report.
OBJECTIVE: To estimate the prevalence of autism spectrum disorders (ASD) among adult psychiatric out-patients; to evaluate the efficacy of a new brief screening questionnaire (ASDASQ). METHOD: 1323 adult psychiatric out-patients were screened by staff. Analysis of psychiatric records of patients (n = 66) scoring high on the ASDASQ yielded 31 patients with a suspected ASD. Twenty-two of these patients were clinically examined. Three psychometric aspects of the questionnaire were studied. RESULTS: Seventeen patients were found by clinical examination to have an ASD. Since two patients scoring low on the ASDASQ were known to have an ASD, at least 19 patients in this population (1.4%) had a definite ASD. Seventeen of the ASD patients had been previously diagnosed with other psychiatric disorders, most frequently schizophrenia (n = 5). Of patients attending a treatment centre for severe psychiatric disabilities (n = 499), 3.2% had an ASD. The ASDASQ showed good reliability across and within raters. Internal consistency was excellent. CONCLUSION: Adult psychiatric patients sometimes have undiagnosed autism spectrum disorders. The ASDASQ can be useful for screening.

ADHD in Swedish 3- to 7-year-old children.
OBJECTIVE: To study characteristics of attention-deficit/hyperactivity disorder (ADHD) in a representative group of clinically impaired young children in Sweden with the disorder. METHOD: One hundred thirty-one children with ADHD (aged 3-7 years) were examined, and their parents were interviewed. Independent parent questionnaire data (Child Behavior Checklist, ADHD Rating Scale-IV, Conners) were collected. For comparison 131 children without ADHD were matched for age, gender, parents' marital status, child's adoption status, and social class. RESULTS: Children with ADHD had extremely high ADHD symptom levels--on average four to eight times higher than the comparison group. Sociodemographic correlates of ADHD symptoms were more pronounced in parent questionnaire data than in parent interview data, underscoring the importance of diagnostic interview when dealing with clinical issues. Very few of the children with ADHD (6%) appeared "normal" with regard to attention/activity level at clinical examination. CONCLUSIONS: Clinic children with a diagnosis of DSM-IV ADHD have typical and impairing symptoms already before starting school. The variance of ADHD in this age group appears to be accounted for by primary psychosocial factors only to a limited degree. It would seem reasonable to establish supportive and treatment measures for these young children so that the psychosocial and academic problems shown by so many individuals with ADHD later in their development might be reduced.

Etiology and pathophysiology of autistic behavior: clues from two cases with an unusual variant of neuroaxonal dystrophy.
Two unrelated individuals with autistic behavior had numerous swollen axon terminals (spheroids) located in specific brain regions relevant to their behavioral symptoms. Spheroids are characteristic of neuroaxonal dystrophy, but the clinical profile and anatomic distribution of the lesions in these two patients differed from those of previously described patients with neuroaxonal dystrophy. Spheroids were numerous in the sensory nuclei of the spinal cord and medulla, specific nuclei and the reticular formation of the brainstem tegmentum, hypothalamus, anterior and dorsomedial thalamus, hippocampus, and cingulate and orbitofrontal cortices. Spheroids were sparse in the primary and association cortices and basal ganglia and absent in the hemispheric white matter. Cerebellar atrophy was present in both cases but associated with spheroids in only one case. These cases represent a new variant of neuroaxonal dystrophy in which behavioral symptoms characteristic of autism dominated the clinical picture. Neuroaxonal dystrophy should be included in the list of diseases that may be found in persons with autism.

The Asperger Syndrome (and high-functioning autism) Diagnostic Interview (ASDI): a preliminary study of a new structured clinical interview.
The development of the Asperger Syndrome (and high-functioning autism) Diagnostic Interview (ASDI) is described. Preliminary data from a clinical study suggest that inter-rater reliability and test-retest stability may be excellent, with kappas exceeding 0.90 in both instances. The validity appears to be relatively good. No attempt was made in the present study to validate the instrument as regards the distinction between Asperger syndrome and high-functioning autism.

Neurocognitive stability in Asperger syndrome, ADHD, and reading and writing disorder: a pilot study.
Boys with Asperger syndrome (n=20), attention-deficit-hyperactivity disorder (n=20), and reading and writing disorder (n=20) were followed up and retested on several neuropsychological measures 1 to 2 years after initial assessments. Wechsler Intelligence Scale for Children (WISC-III) Full Scale, Verbal, and Performance IQ scores remained stable for all diagnostic groups. Kaufman factors and 'fluid' and 'crystallized' abilities were also stable measures. Subtest stability over time, was slightly more variable. There was a tendency for the group with Asperger syndrome to deteriorate over time with respect to logical reasoning abilities. Measures of executive function/attention ('go-no-go' and 'conflict' tests) showed good test-retest stability in all diagnostic groups. This is the first study of its kind.

The comorbidity of ADHD in the general population of Swedish school-age children.
This study examined patterns of comorbid/associated diagnoses and associated problems in a population sample of children with and without DSM-III-R attention-deficit hyperactivity disorder (ADHD). Half (N = 409) of a mainstream school population of Swedish 7-year-olds were clinically examined, and parents and teachers were interviewed and completed questionnaires. The children were followed up 2-4 years later. Eighty-seven per cent of children meeting full criteria for ADHD (N = 15) had one or more and 67% at least two--comorbid diagnoses. The most common comorbidities were oppositional defiant disorder and developmental coordination disorder. Children with subthreshold ADHD (N = 42) also had very high rates of comorbid diagnoses (71% and 36%), whereas those without ADHD (N = 352) had much lower rates (17% and 3%). The rate of associated school adjustment, learning, and behaviour problems at follow-up was very high in the ADHD groups. We concluded that pure ADHD is rare even in a general population sample. Thus, studies reporting on ADHD cases without comorbidity probably refer to highly atypical samples. By and large, such studies cannot inform rational clinical decisions.

Ten-year follow-up of adolescent-onset anorexia nervosa: psychiatric disorders and overall functioning scales.
The aim of this study was to assess prospectively the long-term outcome in a representative sample of teenage-onset anorexia nervosa (AN) in respect of psychiatric disorders and overall outcome. Fifty-one AN cases, recruited by community screening, with a mean age of onset of 14 years, was contrasted with 51 matched comparison cases at a mean age of 24 years (10 years after AN onset). All 102 cases had been examined at ages 16 and 21 years. At 24 years all probands were interviewed regarding psychiatric disorders (SCID-I) and overall outcome (Morgan-Russell assessment schedule, the GAF). There were no deaths at 10-year follow-up. One in four in the AN group had a persisting eating disorder (ED), including three who still had anorexia nervosa. Lifetime diagnoses of affective disorders and obsessive-compulsive disorder were over-represented in the AN group. Outcome according to Morgan-Russell was poor in 27%, intermediate in 29%, and good in 43%. According to the GAF, half the AN group had a poor psychosocial functioning. These were subjects with either a persisting ED or lifelong problems with social interaction or obsessive-compulsive behaviour. Ten-year outcome of teenage-onset AN is favourable in the majority of cases; most individuals have recovered from their ED and have no other axis I disorder. However, half the AN group reported poor psychosocial outcome, in most cases explained by a persisting ED or chronic obsessive-compulsive behaviour/social interaction problems.

Juvenile and young adult mentally disordered offenders: the role of child neuropsychiatric disorders.
A retrospective study of the prevalence of child neuropsychiatric disorders was done involving pervasive developmental disorder (PDD), attention-deficit/hyperactivity disorder (ADHD), and Tourette syndrome in young offenders (15-22 years, n = 126) consecutively referred for presentencing forensic psychiatric investigation (FPI) in Stockholm, Sweden. Most offenders were referred for FPI because of serious offenses. Case report sheets were prepared, and retrospective neuropsychiatric DSM IV diagnoses were made by the first two authors. For best-estimated diagnoses, the case report sheets were then submitted to the fifth author, a child neuropsychiatrist with expertise in this area. Fifteen percent of the subjects had a definite diagnosis of ADHD, and another 15 percent had PDD, including 12 percent PDD not otherwise specified (NOS) and 3 percent Asperger syndrome. Autistic disorder was not found in any case. Tourette syndrome occurred in two percent of the cases. The rate of PDD is particularly striking. Neuropsychiatric diagnoses had been determined in the FPI in only a few cases. The contribution of constitutional problems to later criminal development may have been underestimated.

[Neuropsychiatric problems among children are signigicantly underdiagnosed. Intervention programs result in better and less expensive care].
Neuropsychiatric problems (Asperger syndrome, ADHD, reading and writing disorders) affect 6-10 per cent of all children in Sweden. Many of these disorders are never diagnosed. As a consequence, secondary behaviour problems and impaired family relations often follow. A study of 60 families with at least one child affected by one of the above mentioned disorders shows that quality of life can be increased and problems reduced if parents and children are informed of the child's disabilities and the child receives a special education programme. Families who do not receive this special treatment more often apply for medical care from other (more expensive) sources. Quite often do they find this treatment unsatisfactory.

Typical neuroleptics in child and adolescent psychiatry.
This paper reviews the use of typical ("old") neuroleptics in the treatment of child and adolescent psychiatric disorders. Very few methodologically sound papers have been published in the field. It is concluded that typical neuroleptics should be used sparingly and only in severe and incapacitating disorders such as some psychotic conditions and handicaping tic disorders. Side effects have to be very carefully monitored.

Autism spectrum and attention-deficit disorders in girls. Some neuropsychological aspects.
This study compared the neuropsychological test profiles of non-mentally retarded girls and boys consecutively referred to a neuropsychiatric clinic and those of contrast cases of girls from mainstream classrooms of one Göteborg school district. To avoid overreliance on the male prototype with regard to diagnostic criteria the clinical group comprised a mixed sample of girls and boys without diagnostic subgrouping. Clinic girls had a lower IQ than comparison girls. Girls were more impaired than the boys with respect to executive functions and scored less well on theory of mind tasks. Previous studies have shown girls with autism and mental retardation to be more severely affected than boys both with regard to level of intellectual functioning and overall measures of brain dysfunction. The present study indicates that clinic girls with a variety of neuropsychiatric disorders at higher levels of intellectual functioning (some of which met diagnostic criteria for autism spectrum disorder) may also be more severely affected than boys with corresponding types of "surface" problems.
