- OBJECTIVE: The authors describe personality development and disorders in relation to symptoms of attention deficit hyperactivity disorder (ADHD) and autism spectrum disorders. METHOD: Consecutive adults referred for neuropsychiatric investigation (N=240) were assessed for current and lifetime ADHD and autism spectrum disorders and completed the Temperament and Character Inventory. In a subgroup of subjects (N=174), presence of axis II personality disorders was also assessed with the Structured Clinical Interview for DSM-IV Personality Disorders (SCID-II). RESULTS: Patients with ADHD reported high novelty seeking and high harm avoidance. Patients with autism spectrum disorders reported low novelty seeking, low reward dependence, and high harm avoidance. Character scores (self-directedness and cooperativeness) were extremely low among subjects with neuropsychiatric disorders, indicating a high overall prevalence of personality disorders, which was confirmed with the SCID-II. Cluster B personality disorders were more common in subjects with ADHD, while cluster A and C disorders were more common in those with autism spectrum disorders. The overlap between DSM-IV personality disorder categories was high, and they seem less clinically useful in this context. CONCLUSIONS: ADHD and autism spectrum disorders are associated with specific temperament configurations and an increased risk of personality disorders and deficits in character maturation.

- 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: Although weight history is relevant in predicting eating disorder symptom severity, little is known about its role in the etiology of anorexia nervosa (AN). This study aimed to determine whether BMI or BMI trajectory differed between individuals who later developed adolescent-onset AN and a comparison group of HCs between school grades 1 through 6.METHOD: This study was based on longitudinal data that identified 51 adolescents with AN and 51 matched HCs. Cases were identified through community screening in Sweden and included individuals born in 1969 through 1977. Measured weights and heights were retrieved and BMIs and weight trajectories of the AN and HC groups were compared using growth curve analysis. Main outcome measures included measured BMI and BMI trajectories from grades 1-6. Secondary outcomes examined included ponderal index at birth and maternal body weight.RESULTS: Individuals who later developed AN had higher BMIs than HCs between grades 1 and 6, by an average of 1.42 BMI-units. There was no difference in rate of weight gain between groups. Ponderal index at birth was higher for the AN as compared with HC group. Maternal weight did not differ significantly between groups.DISCUSSION: These findings, combined with those previously reported on the premorbid BMIs of those with bulimia nervosa, suggest that a predisposition toward elevated premorbid BMIs during childhood characterizes those who later develop anorexia or bulimia nervosa. These findings are consistent with a transdiagnostic perspective and suggest shared risk factors for AN and obesity. © 2016 Wiley Periodicals, Inc.(Int J Eat Disord 2016).

- 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.

- 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 prevention of aggressive behaviours is a core priority for psychiatric clinical work, but the association between the diagnostic concepts used in psychiatry and aggression remains largely unknown. Outpatients referred for psychiatric evaluations of childhood-onset neuropsychiatric disorders (n = 178) and perpetrators of violent crimes referred to pre-trial forensic psychiatric investigations (n = 92) had comprehensive, instrument-based, psychiatric assessments, including the Life History of Aggression (LHA) scales. Total and subscale LHA scores were compared to the categorical and dimensional diagnoses of childhood and adult DSM-IV axis I and II mental disorders, general intelligence (IQ), Global Assessment of Functioning (GAF), and personality traits according to the Temperament and Character Inventory (TCI). Overall, the two groups had similar LHA scores, but the offender group scored higher on the Antisocial subscale. Higher total LHA scores were independently associated with the hyperactivity facet of attention-deficit/hyperactivity disorder (AD/HD), childhood conduct disorder, substance-related disorders, and low scores on the Cooperativeness character dimension according to the TCI. IQ and GAF-scores were negatively correlated with the LHA subscale Self-directed aggression. Autistic traits were inversely correlated with aggression among outpatients, while the opposite pattern was noted in the forensic group. The findings call for assessments of aggression-related behaviours in all psychiatric settings.
