- 1941 ofthe 3-6-year-old children living in a community outside Gbteborg on the Swedish west coast were screened with a view to identifying all individuals with severe degrees of autistic behaviour. All children in the population were known to well baby clinic staff, and any child suspected of suffering from autism was referred to a specialized clinical research team. The nurses and doctors working in the well baby clinics were well informed about autism. Clinical and ADI-R diagnoses of autism were established after thorough clinical assessments of each suspected case. All children were seen at least twice, and all were over the age of 3 years at the time of diagnosis. The general population prevalence for autism was 3 I in I o,ooo children (9; percent confidence interval 7/ g;). Classic Kanner autism was found in I o in Io,ooo children (9; percent confidence interval-4/24). These rates appear to reflect higher rates than previously reported. Some reasons for the possibly higher prevalence are discussed.

Auditory Integration Training in Children with Autism : Brief Report of an Open Pilot Study
- 1997
-
Ingår i: Autism. - : SAGE Publications. - 1362-3613 .- 1461-7005. ; 1:1, s. 97-100

Tidskriftsartikel (refereegranskat)abstract
- Nine children aged 3-I 6 years with an autistic disorder were given auditory integration training for half-hour sessions during 10 days according to guidelines suggested by Guy Berard. No significant change in overall autistic symptom level could be documented 9 months later. However a small but non-significant reduction of 'sensory problems' as rated by the Autism Behaviour Checklist was noted.

'Theory of mind' in the brain. Evidence from a PET scan study of Asperger syndrome.
- 1996

- The ability to attribute mental states to others ('theory of mind') pervades normal social interaction and is impaired in autistic individuals. In a previous positron emission tomography scan study of normal volunteers, performing a 'theory of mind' task was associated with activity in left medial prefrontal cortex. We used the same paradigm in five patients with Asperger syndrome, a mild variant of autism with normal intellectual functioning. No task-related activity was found in this region, but normal activity was observed in immediately adjacent areas. This result suggests that a highly circumscribed region of left medial prefrontal cortex is a crucial component of the brain system that underlies the normal understanding of other minds.

The puzzle of autism: an ophthalmologic contribution.
- 1998
-
Ingår i: Transactions of the American Ophthalmological Society. - 0065-9533. ; 96
-
Tidskriftsartikel (refereegranskat)abstract
- A previous study of 86 thalidomide-affected subjects with ophthalmic manifestations revealed the unexpected finding of autism in 4 of the 5 severely retarded individuals. The subjects had anomalies associated with an early gestational effect of thalidomide, including facial nerve palsy and incomitant strabismus. Because autism has been observed in a few cases of Möbius sequence (Möbius syndrome), a condition characterized by involvement of the sixth and seventh cranial nerves, the similarity to early thalidomide embryopathy suggested a relation between cranial nerve involvement and autism. The present study was undertaken to further evaluate the association of autism with patients manifesting findings of Möbius syndrome.

Gangliosides in cerebrospinal fluid in children with autism spectrum disorders.
- 1998

- Gangliosides are sialic acid-containing glycolipids found in all cells, especially abundant in nerve cells and mainly situated on outer-membrane surfaces. The aim of this study was to provide data on the concentration of gangliosides in the CSF of children and adolescents with autism spectrum disorders (ASD) - 66 with autistic disorder, and 19 with other autism spectrum disorders. The comparison group consisted of 29 children and adolescents, whose CSF had been sampled to exclude acute infectious CNS disorder. The concentrations of the gangliosides GM1, GD1a, GD1b, and GT1b were determined using a microimmunoaffinity technique. The ASD group had a significantly higher concentration of ganglioside GM1 compared with the comparison group. The GM1 increase could not be explained as secondary to other clinical factors. Mean ganglioside levels did not differentiate subgroups with autistic disorder and those with a more atypical clinical picture, nor subgroups with known medical disorders and those with idiopathic autism. Altered patterns of gangliosides in the CNS might reflect important correlates of pathogenesis in autism.

Language and pragmatic functions in school-age children on the autism spectrum
- 1996
-
Ingår i: European Journal of Disorders of Communication. - 0963-7273. ; 31:4, s. 387-413
-
Tidskriftsartikel (refereegranskat)abstract
- This study examined group differences in language and pragmatic functions across sex-, age- and IQ-matched samples of Asperger syndrome (N = 22), high-functioning autism (N = 11), deficits in attention, motor control and perception (DAMP) (N = 11), and speech and language disorder (SLD) (N = 11) groups. The purpose was to explore possible differentiating features in the fields of vocabulary, comprehension and pragmatics and, in addition, to determine whether Asperger syndrome could be reliably separated from high-functioning autism on these variables. The findings suggest that Asperger syndrome may be associated with higher full-scale and verbal IQ than high-functioning autism; Asperger syndrome may not be associated with better pragmatic skills (as defined in this context) than high-functioning autism; language comprehension may not clearly separate Asperger syndrome and high-functioning autism once the effects of very low IQ are partialled out; both DAMP and SLD can be distinctly separated from Asperger syndrome and autism.

Alexithymia in anorexia nervosa: a controlled study using the 20-item Toronto Alexithymia Scale.
- 1997
-
Ingår i: Acta Psychiatrica Scandinavica. - : Wiley. - 0001-690X .- 1600-0447. ; 95:5, s. 385-388

Tidskriftsartikel (refereegranskat)abstract
- The 20-item Toronto Alexithymia Scale (TAS) was completed at the age of 22 years by individuals who had previously suffered from anorexia nervosa (AN), and also by members of a comparison group. The AN and comparison groups had been recruited from community samples. Overall, the TAS scores did not clearly discriminate between the two groups. However, the AN group was significantly more often represented among subjects with the highest TAS scores. A subgroup with empathy disorder tended to have particularly high scores. It is concluded that alexithymia, as defined using the TAS-20, is found only in a subgroup of individuals with AN, and possibly more often in those who are also clinically diagnosed as suffering from empathy disorder. The TAS-20 is not suitable for screening of AN in the general population.
