- BACKGROUND: A subgroup of persons with anorexia nervosa (AN) have been proposed to have sociocommunicative problems corresponding to autism spectrum disorders [ASDs, i.e. DSM-IV pervasive developmental disorders (PDDs): autistic disorder, Asperger's disorder, PDD not otherwise specified (NOS)]. Here, clinical problems, personality traits, cognitive test results and outcome are compared across 16 subjects (32%) with teenage-onset AN who meet or have met ASD criteria (AN+ASD), 34 ASD-negative AN subjects and matched controls from a longitudinal Swedish study including four waves of independent assessments from the teens to the early thirties.MethodThe fourth wave included the Structured Clinical Interview for DSM-IV (SCID)-I and the SCID-II (cluster C, i.e. 'anxious' PDs) interviews, the Asperger Syndrome Diagnostic Interview, self-assessments by the Autism Spectrum Quotient and the Temperament and Character Inventory, neurocognitive tests by subscales from the Wechsler scales, continuous performance tests, Tower of London, and Happé's cartoons. RESULTS: The ASD assessments had substantial inter-rater reliability over time (Cohen's κ between 0.70 and 0.80 with previous assessments), even if only six subjects had been assigned a diagnosis of an ASD in all four waves of the study, including retrospective assessments of pre-AN neurodevelopmental problems. The AN+ASD group had the highest prevalence of personality disorders and the lowest Morgan-Russell scores. The non-ASD AN group also differed significantly from controls on personality traits related to poor interpersonal functioning and on neurocognitive tests. CONCLUSIONS: A subgroup of subjects with AN meet criteria for ASDs. They may represent the extreme of neurocognitive and personality problems to be found more generally in AN.

- Objective: To examine Facial Emotion Recognition (FER) and visual scanning behavior (eye-tracking) during FER in women long-term recovered from teenage-onset anorexia nervosa (recAN) with and without autism spectrum disorder (±ASD) and age-matched comparison women (COMP), using a sensitive design with facial emotion expressions at varying intensities in order to approximate real social contexts. Method: Fifty-seven 38–47-year-old women (26 recAN of whom six with ASD, 31 COMP) participated in the study. They completed a non-verbal FER task, consisting of matching basic emotions at different levels of expression intensity with full emotional expressions. Accuracy, response time and visual scanning behavior were measured. Results: There were no differences between recAN-ASD and COMP in FER accuracy and visual scanning behavior during FER, including eye viewing and hyperscanning. In an exploratory analysis, recAN+ASD were more accurate than recAN-ASD in identifying expressions at low intensity, but not at medium or high expression intensity. Accuracy was not associated with the extent of attention to the eye region. Discussion: Our data indicate that women long-term recovered from adolescent-onset AN do not have deficits in basic FER ability and visual scanning behavior during FER. However, the presence of comorbid ASD might affect face processing in recovered AN. Future studies investigating basic FER in acute and recovered AN and other conditions need to ensure that the stimuli used are sensitive enough to detect potential deficits.

- 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.

- In a longitudinal study, the authors explore the course of general cognition in anorexia nervosa (AN) over time and compare general cognitive problems, executive function deficits, attentional problems and visuomotor dysfunctions across AN individuals and healthy controls. A community-based sample of adolescent onset AN cases (n=40-47) was contrasted with an age-, sex- and school matched comparison group (n=47-51) on the Wechsler Adult Intelligence Scale-Revised, the Wisconsin Card Sorting Test and Luria word recall test at a mean age of 24 years. Only two of the cases tested were underweight at the time of the study. The Wechsler scale had also been administered when the groups had a mean age of 21 years. There were few differences across the two groups even though the comparison group performed significantly better on the Object Assembly subtest of the WAIS-R. IQ increased slightly but significantly over time in both groups. There was no relationship between level of starvation and poor results on tests in the AN group. A subgroup of the subjects had autism spectrum disorders. In this subgroup there were cases with test profiles similar to those observed in autism and Asperger syndrome, just as there had been on testing three years previously. Ten years after AN onset, the former AN cases showed no major neuropsychological deficits. A subgroup with autistic features had test profiles similar to those observed in autism spectrum disorders. The AN group as a whole showed poor results on the object assembly subtest indicating weak central coherence with a tendency to focus on details at the expense of configural information. This cognitive style may account for their obsession with details, with implications for psychoeducational approaches in treatment programmes/interventions.

- The study objective was to examine the prevalence and course of depressive disorders (DDs) in teenage-onset anorexia nervosa (AN) over a period of 10 years. Fifty-one adolescents with AN and a sex- and age-matched control group (n = 51) were assessed at ages 16, 21, and 24 years. Probands and controls were examined in depth using semistructured and structured interviews. Their parents were interviewed on the occasion of the first examination. DDs were assessed using DSM-III-R criteria. Subjects with AN had a greatly increased rate of DDs (85%) of all kinds and at all ages as compared with control subjects. The risk of DD during the follow-up period from 21 up to and including 24 years could be predicted by diagnostic group status and the presence of DD during the period from 16 to 21 years, while the risk of DD during the follow-up period from 16 up to and including 21 years was solely predicted by the presence of AN at age 16 years. Long-term resolution of the eating disorder (ED) was associated with the absence of mood disorder or vice versa. Bipolar disorder (BP) occurred at roughly the expected rate (11%) among subjects (probands and controls) with major depression (MDD). In conclusion, depression is a very common comorbid problem in AN: more than four of five individuals with teenage-onset AN had at least one episode of DSM-III-R depression (MD or dysthymia [DT]) within 10 years after onset of the ED. AN appears to trigger the first episode of depression, but once it is manifest, depression predicts further depressive episodes.

- Background: Long-term consequences of comorbid autism spectrum disorder (ASD) in individuals with anorexia nervosa (AN) are inadequately investigated. Methods: In the 1980s, 51 adolescent-onset AN cases (AN group) and 51 matched controls (COMP group) were recruited from the community. They have been examined on five occasions. The four last assessments included the Morgan-Russell Outcome Assessment Schedule (MROAS) to assess eating disorder outcomes (weight, dieting, menstruation), and related problems including psychiatric, psychosexual and socioeconomic state. In the present study, at age 44, when 30 years had elapsed, MROAS data were compared with previous results. At age 16, 21, 24 and 32 years, all individuals had been assessed regarding ASD. At the 30-year follow-up, the impact of the ASD on the MROAS data was analysed. Results: In the AN group, all core anorectic symptoms (weight, dieting, menstruation) were on a par with the COMP group at the 30-year follow-up, but the positive outcomes were limited to those who had never had an ASD diagnosis. Psychiatric state was significantly worse in the AN group, particularly in the subgroup who had an ASD diagnosis assigned. The AN group—again particularly those with ASD—had a more negative attitude to sexual matters than the COMP group. The AN group had worse outcomes than the COMP group for ‘personal contacts’, ‘social contacts,’ and ‘employment record’ at the 30-year follow-up and the outcomes were worse the more often an ASD diagnosis had been assigned. Limitations: Rare data collection points throughout 30 years (only 5 assessments). ASD was assessed in the first four studies but was not assessed again at the 30-year follow-up. Conclusions: Mental health, psychosexual, and socioeconomic status were compromised up to 30 years after AN onset. Coexisting ASD contributed to the poor outcome. Core anorectic symptoms had “normalised” three decades after AN onset. Plain English summary: Some individuals with anorexia nervosa (AN) also suffer from autism. In this study we have investigated outcome of AN 30 years after the onset of AN and whether the presence of autism affects the outcome. Since the 1980s we have followed 51 individuals with teenage-onset AN and 51 healthy controls. They have been examined on five occasions, and an instrument that measures symptoms of AN (weight, dieting, body image), psychiatric symptoms, ability to work, and relationships with partner, family, and friends has been used to assess outcome. Autism was assessed in the first four studies. Symptoms of AN had normalised at 30-year follow-up, but only among those without autism. Psychiatric symptoms, ability to work, and relationships were issues that persisted after 30 years in the AN group, and those who had both autism and a history of AN had even more pronounced problems in these areas. The AN group had a more negative attitude to sexual matters than the control group, the outcome was worse the more often an autism diagnosis had been assigned. Conclusions: Mental health, psychosexual, and socioeconomic status are affected up to 30 years after AN onset, particularly among those with autism.
