- 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.

- We studied self-concept and psychological well-being in children with hand deformities and upper limb deficiencies. Ninety-two children, 53 boys, 39 girls, aged 9-11 years were included. The children were divided into two subgroups - one with milder (less visible) deformities and one with severe (more complex and visible) finger-hand-arm deformities. Of the 92 children, 79 had received reconstructive surgery, and 13 had been treated with prostheses. The Piers-Harris Children's Self-Concept Scale (PHCSCS) was used to measure self-esteem and well-being. Overall PHCSCS scores showed that the whole hand deformity group had 'good' self-concept with mean scores in excess of 60 points, equal to a comparison group of healthy children. Within the hand deformity group, those with mild deformities had lower scores than those with severe deformities. This result was also found in the group of boys but not in the girls. The children with severe deformities had even higher scores than the comparison group regarding the subscale 'Intellectual and School Status'. The children with milder deformities had lower scores than the comparison group regarding the subscale 'Popularity'.

Tidskriftsartikel (refereegranskat)abstract
- 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.

Screening for genomic rearrangements and methylation abnormalities of the 15q11-q13 region in autism spectrum disorders.
- 2009

Ingår i: Biological Psychiatry. - : Elsevier BV. - 0006-3223. ; 66:4, s. 349-359

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Maternally derived duplications of the 15q11-q13 region are the most frequently reported chromosomal aberrations in autism spectrum disorders (ASD). Prader-Willi and Angelman syndromes, caused by 15q11-q13 deletions or abnormal methylation of imprinted genes, are also associated with ASD. However, the prevalence of these disorders in ASD is unknown. The aim of this study was to assess the frequency of 15q11-q13 rearrangements in a large sample of patients ascertained for ASD. METHODS: A total of 522 patients belonging to 430 families were screened for deletions, duplications, and methylation abnormalities involving 15q11-q13 with multiplex ligation-dependent probe amplification (MLPA). RESULTS: We identified four patients with 15q11-q13 abnormalities: a supernumerary chromosome 15, a paternal interstitial duplication, and two subjects with Angelman syndrome, one with a maternal deletion and the other with a paternal uniparental disomy. CONCLUSIONS: Our results show that abnormalities of the 15q11-q13 region are a significant cause of ASD, accounting for approximately 1% of cases. Maternal interstitial 15q11-q13 duplications, previously reported to be present in 1% of patients with ASD, were not detected in our sample. Although paternal duplications of chromosome 15 remain phenotypically silent in the majority of patients, they can give rise to developmental delay and ASD in some subjects, suggesting that paternally expressed genes in this region can contribute to ASD, albeit with reduced penetrance compared with maternal duplications. These findings indicate that patients with ASD should be routinely screened for 15q genomic imbalances and methylation abnormalities and that MLPA is a reliable, rapid, and cost-effective method to perform this screening.

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

Ingår i: Neuroreport. - 0959-4965. ; 8:1, s. 197-201

Tidskriftsartikel (refereegranskat)abstract
- 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.

Autism spectrum conditions in individuals with Mobius sequence, CHARGE syndrome and oculo-auriculo-vertebral spectrum: diagnostic aspects.
- 2010

Ingår i: Research in Developmental Disabilities. - : Elsevier BV. - 0891-4222 .- 1873-3379. ; 31:1, s. 9-24
-
Tidskriftsartikel (refereegranskat)abstract
- As part of multidisciplinary surveys of three Behavioural Phenotype Conditions (BPCs); Möbius sequence (Möbius), CHARGE syndrome (CHARGE) and oculo-auriculo-vertebral spectrum (OAV), autism spectrum conditions (ASCs) was diagnosed in 45%, 68% and 42% of the individuals, respectively. Diagnostic difficulties due to additional dysfunctions such as mental retardation (MR), impaired vision, reduced hearing and cranial nerve dysfunction, were experienced in all three BPC groups. The applicability of current autism diagnostic instruments, such as the Autism Diagnostic Interview-Revised (ADI-R), the Childhood Autism Rating Scale (CARS) and the Autistic Behaviour Checklist (ABC), in individuals with ASCs and Möbius/CHARGE/OAV was analysed. Use of an extensive battery of diagnostic instruments, including both observational schedules and parent interviews, and, if possible, independent judgements from two clinicians, is essential in the diagnostics of ASCs in these individuals. Further, in individuals who are deaf and blind the applicability of current autism diagnostic instruments is highly questionable.

Tidskriftsartikel (refereegranskat)abstract
- As part of a multidisciplinary study, the rate of autism spectrum disorder (ASD), learning disability (LD), and brain abnormalities was examined in 20 participants (12 males, 8 females; age range 8mo-17y, mean age 8y 1mo) diagnosed as falling within the oculoauriculovertebral spectrum (OAV). A neuropsychiatric examination was performed, including standardized autism diagnostic interviews. Two individuals met diagnostic criteria for autism, one for autistic-like condition, and five for autistic traits. Four patients had mild LD, three severe LD, two profound LD, and two borderline intellectual functioning. Neuroimaging indicated cerebral abnormalities in more than half of the patients. Abnormalities of white/grey matter were found in more than half of examined individuals; enlargement of ventricles in more than a third. Results indicate that at least a subgroup of ASD may be associated with errors in early embryonic brain development. Awareness of the coexistence of OAV/ASD is important in habilitation care of individuals with OAV.

Tidskriftsartikel (refereegranskat)abstract
- The rate of autism spectrum disorders (ASDs) and brain abnormalities was analyzed in 31 individuals (15 males, 16 females; age range 1mo to 31y, mean age 8y 11mo) with CHARGE association, as part of a multidisciplinary study. A meticulous neuropsychiatric examination was performed, including standardized autism diagnostic interviews. Judgement regarding ASDs was impossible in three infants and three patients who were deaf and blind. Five individuals met diagnostic criteria for autism, five for an autistic-like condition, and seven for autistic traits. Brain abnormalities were indicated in almost three-quarters of examined individuals, and midline abnormalities of the forebrain in one-third. Awareness of the coexistence of CHARGE and ASDs is important in habilitation care in CHARGE. Moreover, the results indicate that a subgroup of ASDs may be associated with errors in early embryonic brain development.

) Autistic spectrum disorders in Mobius sequence: a comprehensive study of 25 individuals

Tidskriftsartikel (refereegranskat)abstract
- 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.
