- Typically, developing humans innately place subjective value on social information and orient attention to it. This can be shown through tracking of gaze patterns and pupil size, the latter of which taps into an individual's cognitive engagement and affective arousal. People with Autism Spectrum Disorder (ASD) present with atypical social, communicative and behavioral patterns, but underlying substrates of these behavioral differences remain unclear. Moreover, due to high comorbidity with other neurodevelopmental disorders, it is often difficult to distinguish which differences are distinctive to ASD. In this study, a group of 35 adolescents and young adults with neurodevelopmental disorders were tested to investigate the processing of social and non-social scenes in individuals who meet the diagnostic criteria for autism and those who do not. Eye tracking and pupillometry measures were collected while participants observed images of tightly controlled natural scenes with or without a human being. Contrary to individuals without autism diagnosis, participants with autism did not show greater pupillary response to images with a human. Participants with autism were slower to fixate on social elements in the social scenes, and this latency metric correlated with clinical measures of poor social functioning. The results confirm the clinical relevance of eye-tracking and pupillometric indices in the field of ASD. We discuss the clinical implications of the results and propose that analysis of changes in visual attention and physiological level to social stimuli might be an integral part of a neurodevelopmental assessment.

Co-existing disorders in ADHD -- implications for diagnosis and intervention.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: It is only recently that "comorbidity" in ADHD has come to the forefront as one of the most important aspects of the disorder. It is agreed that, often, these problems are at least as important as ADHD in contributing to the longer term outcome in the individual child. OBJECTIVE: To provide the reader with basic information about clinics and treatment of "comorbidity" in ADHD. METHOD: Review of the empirically based literature. RESULTS: ADHD exists in a surprisingly high frequency together with a broad range of child neuropsychiatric disorders. This is accompanied with many still unresolved treatment problems. CONCLUSION: It would not be appropriate to develop ADHD-services where clinicians would only have expertise in ADHD as such. Anyone working with children, adolescents and adults with ADHD would need to have training in general neuropsychiatry. Further research in this field is urgently needed.

Extreme ("pathological") demand avoidance in autism: a general population study in the Faroe Islands.
- 2015
-
Ingår i: European child & adolescent psychiatry. - : Springer Science and Business Media LLC. - 1435-165X .- 1018-8827. ; 24:8, s. 979-984

Tidskriftsartikel (refereegranskat)abstract
- Research into Pathological Demand Avoidance (PDA), which has been suggested to be a subgroup within the Autism Spectrum Disorder (ASD), is almost nonexistent in spite of the frequent reference to the condition in clinical practice. The total population of 15 to 24-year-olds in the Faroe Islands was screened for ASD, and 67 individuals were identified who met diagnostic criteria for ASD (corresponding to a general population prevalence of ASD of almost 1%). Of these 67, 50 had parents who were interviewed using the Diagnostic Interview for Social and Communication Disorders (DISCO-11) which contains 15 "PDA-specific" items. Nine individuals met criteria for "possible clinical diagnosis of PDA", meaning that almost one in five of all with ASD also had indications of having had PDA in childhood, and that 0.18% of the total population had had the combination of ASD and PDA. However, at the time of assessment, only one of the 9 individuals with possible PDA still met "full criteria". PDA possibly constitutes a considerable minority of all cases with ASD diagnosed in childhood, but criteria for the condition are unlikely to be still met in later adolescence and early adult life.

Infantile autism: a total population study of reduced optimality in the pre-, peri-, and neonatal period.
- 1983
-
Ingår i: Journal of Autism and Developmental Disorders. - 0162-3257. ; 13:2, s. 153-166

Tidskriftsartikel (refereegranskat)abstract
- Twenty-five autistic children, constituting a total population sample of children with infantile autism, were compared with 25 sex- and maternity-clinic-matched controls for occurrence of reduced optimality in the pre-, peri, and neonatal period, as noted in medical records. Autistic children showed greatly increased scores for reduced optimality, especially with regard to prenatal factors. The findings are at odds with early reports that children with autism had not suffered potential brain injury. The reasons for the discrepancy are discussed.

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- Autism was long considered to be a very rare disorder, the best defined in child psychiatry (Rutter & Schopler, 1992), and one that occurred in isolation, often with no comorbidity (except, possibly, mental retardation) and presumably with one etiology. It is now clear that autism in its classic variant is but part of a broader spectrum of disorders that include not only “autistic disorder” (as defined by DSM-IV) but also a number of conditions, including Asperger disorder and so-called pervasive developmental disorders not otherwise specified (PDDNOS)/atypical autism (Wing & Potter, 2002). It has also become generally accepted that these “autism spectrum disorders” (ASDs, including autistic disorder) are much more common than previously assumed, with overall childhood prevalence usually reported at just under 1% (Gillberg et al., 2006). To complicate things, genetic studies have shown that ASDs extend into “lesser variants” and “broader phenotypes” with some characteristic autism features but with little or no clinical impairment. Population studies suggest that such lesser variants or features of autism occur in several percent of children (Briskman, Happé, & Frith, 2001; Constantino & Todd, 2003; Posserud et al., 2006). The comorbidity issue in autism has not been resolved, and authorities in the field still argue about whether autism can be associated with other disorders, including ADHD. Both the DSM-IV and ICD-10 include a section of the diagnostic criteria that is difficult to interpret but that would tend to make researchers and clinicians loathe to diagnose coexisting/comorbid ADHD in ASD. Conversely, ADHD has long been agreed to be a common type of childhood behavior disorder and one that does blend into normality.

The Asperger Syndrome (and high-functioning autism) Diagnostic Interview (ASDI): a preliminary study of a new structured clinical interview
- 2001

Ingår i: Autism. - 1362-3613. ; 5:1, s. 57-66

Tidskriftsartikel (refereegranskat)abstract
- 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.

- OBJECTIVE: Prospective study of attention, executive functions, and mentalizing abilities in a representative sample of teenage-onset anorexia nervosa (AN). METHOD: A total of 51 AN cases recruited after community screening were contrasted with 51 matched comparison cases 18 years after AN onset. Neuropsychological tests had been done at 21, 24, and 32 years (18 years after AN onset). RESULTS: The AN-group had more attention, executive function, and mentalizing problems. Some of these problems had been present at all three follow-up occasions. CONCLUSIONS: AN is associated with a range of neuropsychological problems that are present long after the eating disorder per se is no longer an important feature.
