Neurodevelopmental and other psychiatric disorders in 22q11.2 deletion syndrome from childhood to adult age: Prospective longitudinal study of 100 individuals.

The 22q11.2 deletion syndrome (22q11.2DS), affects physical as well as cognitive and emotional functioning with increased risk for psychiatric and behavioral problems. This longitudinal study of 79 individuals (18-50 years) with 22q11.2DS investigated neurodevelopmental (NDD) and psychiatric disorders in adulthood, evaluated the stability of childhood diagnoses over time, and examined associations between clinical characteristics in childhood/adolescence and diagnostic outcome in adult age. Examination using validated instruments for cognitive, psychiatric, and global functional problems in the context of an in-depth clinical evaluation found adult age stability of NDD diagnoses made in childhood, however, rates increased at follow-up. Rates of anxiety, mood, and psychotic disorders were high, with a majority meeting diagnostic criteria for one or more psychiatric disorder. The rate of psychotic disorders was much lower compared to many other studies. Variability in functioning at follow-up was primarily associated with intellectual ability at T1. The findings obtained highlight the increased risk of NDD and psychiatric problems and of cognitive impairment and reduced levels of global functioning over time. Results emphasize the importance of clinical follow-up to enable appropriate support for the promotion of optimal health along with a need for future research on effective interventions and treatment strategies.

Healthcare utilization and psychiatric morbidity in violent offenders: findings from a prospective cohort study.

PURPOSE: Although persistent offenders with histories of imprisonment and violence have disproportionate high rates of psychiatric disorders, little is known of their psychiatric healthcare utilization (HCU) and HCU-associated factors. This study aimed to explore psychiatric HCU, psychiatric morbidity, and psychotropic prescription drugs in violent offenders with a history of incarceration. METHODS: Male offenders aged 18-25 (n = 266) imprisoned for violent and/or physical sexual offenses were clinically assessed in 2010-2012 and prospectively followed in Swedish national registries through 2017. Register-based information regarding HCU, psychiatric morbidity, and psychotropic drugs was tracked and compared with a general population group (n = 10,000) and across offending trajectory groups. Baseline risk factors were used to explain prospective psychiatric HCU in violent offenders. RESULTS: Violent offenders used less general healthcare and psychiatric outpatient care, but more psychiatric inpatient care and were more often given psychiatric diagnoses and psychotropic drugs than the general population. Participants previously assigned to persisting offending trajectory groups had higher rates of psychiatric HCU than those assigned to a desisting trajectory. In multivariable regression models, psychiatric HCU was associated with anxiety disorders, prior psychiatric contact, placement in a foster home, psychopathic traits, low intellectual functioning, and persistent offending. CONCLUSIONS: Violent offenders are burdened by extensive and serious psychiatric morbidity and typically interact with psychiatric healthcare as inpatients rather than outpatients. Knowledge about their backgrounds, criminal behaviors, and psychiatric statuses can aid the planning of psychiatric services for this troublesome group.

Association Between Intellectual Functioning and Autistic Traits in the General Population of Children.

Autistic traits are continuously distributed in the general population. The associations between autistic traits and intellectual functioning and/or behavioural difficulties, and the impact of intellectual functioning on behavioural difficulties are unclear. The study aims to describe the distribution of autistic traits in a population-based cross-sectional sample of children. Further aims are to examine the association between intellectual functioning and autistic traits, and between autistic traits and behavioural difficulties. Wechsler scales and ratings of autistic traits and behavioural problems in 874 children aged 7-9 years in the Swedish Environmental Longitudinal Mother and Child, Asthma and Allergy (SELMA) study were assessed. We found a continuous distribution of autistic traits. Intellectual functioning was negatively associated with autistic traits but not with behavioural difficulties. Behavioural difficulties were associated with autistic traits.

Number of words at age 2.5 years is associated with intellectual functioning at age 7 years in the SELMA study.

AIM: We examined the association between the number of words used at age 2.5 years and deficits in intellectual functioning at age 7 years, in 549 children, and whether such association is confirmed by parental concern about the child's development. METHODS: Parental reports of how many words their children used at age 2.5 years were analysed for the association to intellectual functioning (assessed with Wechsler Intelligence Scale for Children - Fourth Edition,WISC-IV) at age 7 years using linear regression, adjusting for sex, maternal education level, parental IQ and smoking during pregnancy. Parental concern at age 7 years was examined with the Early Symptomatic Syndromes Eliciting Neurodevelopmental Clinical Examinations-Questionnaire (ESSENCE-Q). RESULTS: Adjusted linear regression showed that use of 50 words or fewer at age 2.5 years, relative to use of more than 50 words, was associated with lower scores of Full-scale IQ (B = 7.27, p = 0.001), verbal comprehension (B = 8.53, p < 0.001), working memory (B = 9.04, p < 0.001) and perceptual reasoning (B = 4.21, p = 0.045), in the WISC-IV, at age 7 years. Parental concern was more common in the group that used 50 words or fewer (Mann-Whitney U test, p = 0.011). CONCLUSION: This easily accessible measure of number of words seems to be a valuable marker for intellectual functioning later in life.

The road to diagnosis and treatment in girls and boys with ADHD - gender differences in the diagnostic process.

INTRODUCTION: The number of referrals for diagnostic assessments of Attention Deficit/Hyperactivity Disorder (ADHD) has increased in the last decade. There is a lack of studies examining the diagnostic process and the treatment provided, particularly from a gender perspective. METHODS: From a consecutive cohort of Child and Adolescent Psychiatric (CAP) outpatients, the medical records of 50 boys and 50 girls (under 18 years of age) with a diagnosis of ADHD were selected by an Excel random numbers generator. Data about referral reason, diagnostic process and treatment were analysed. RESULTS: Emotional symptoms were more common as a reason for referral to CAP among girls, whereas neurodevelopmental disorders were more common among boys. Compared to the boys, the girls were older at first visit to CAP and at the ADHD diagnosis. The girls had had more visits to the clinic prior to the ADHD diagnostic decision and had more often been prescribed non-ADHD medication both before and after the ADHD diagnosis. The rate of ADHD medication was similar in boys and girls. Girls had more often been admitted to a CAP inpatient care unit prior to the ADHD diagnosis due to acute psychiatric symptoms, and had received more individual psychotherapeutic counselling. CONCLUSION: The results highlight the need for broader psychiatric investigations including neuropsychiatric symptoms in girls referred for 'emotional problems'.

Cognitive functioning in a representative cohort of preschool children with febrile seizures.

AIM: To analyse cognitive functioning in 4-5-year-old children who had experienced febrile seizures (FS) and to assess the importance of complex, recurrent and early vs late onset FS. METHODS: The sample consisted of 73 children, screen positive for FS, drawn from the general child population of 4-year-old children attending their health check-up at child healthcare centres in Gothenburg, Sweden. They were assessed as regards general cognitive ability, visual memory and attention and were contrasted with age norms and with results obtained in 20 children without FS from the same healthcare centres. RESULTS: Of the 73 children, two had a previously diagnosed intellectual disability (ID) (one mild, one moderate) and two further children tested within the study had results corresponding to mild ID. Children with early onset of FS (before age 12 months)-who often had recurrent FS-had lower full-scale, verbal and processing speed IQ than those who had later onset of FS. CONCLUSION: Children with early onset of FS and particularly those with recurrent FS may be at increased risk for poorer verbal and processing speed functioning and therefore at risk of developing cognitive, executive dysfunctions. They would probably benefit from neuropaediatric and neuropsychological follow-up.

The functional impact of cognition in adults with autism spectrum disorders.

Purpose and aim: The overall aim of this study was to examine the relationship between adaptive function and cognitive factors in young adults diagnosed with autism spectrum disorder (ASD) in adult age.Methods: The study included 30 adults (age 18-30) diagnosed with ASD in adulthood. All participants were clinically referred to an adult psychiatric clinic for assessment. Adaptive functioning was measured with Adaptive Behavior Assessment System - 2nd edition (parent version). Wechsler scales of intelligence and Delis-Kaplan Executive Function System were used to measure intelligence and executive function.Results: We found considerable adaptive functioning deficits regardless of Full Scale Intelligence Quotient (FSIQ) level. FSIQ, working memory and processing speed were positively associated with adaptive functioning. No associations were found between adaptive functioning and cognitive flexibility, inhibition, word generation or shifting. Regression analysis showed that working memory and processing speed predicted 23% of the variance in adaptive functioning in this group.Conclusions: The results suggest that cognitive dysfunction could be an important area for intervention to improve adaptive functioning in ASD.

Pupillary Contagion in Autism.

Pupillary contagion is an involuntary change in the observer's pupil size in response to the pupil size of another person. This effect, presumed to be an important adaption for individuals living in groups, has been documented in both typical infants and adults. Here, for the first time, we report pupillary contagion in individuals with autism, a disorder of social communication. We found that, compared with a typical group ( n = 63), individuals with autism ( n = 54) exhibited comparable pupillary contagion when observing pictures of emotional faces, despite less spontaneous attention toward the eye region. Furthermore, the magnitude of the pupillary response in the autism group was negatively correlated with time spent fixating the eye region. The results suggest that even with less looking toward the eyes, individuals with autism respond to the affective and arousal levels transmitted from other individuals. These results are discussed in the context of an overarousal account of socioaffective-processing differences in autism.

Diagnostic validity of the MINI-KID disorder classifications in specialized child and adolescent psychiatric outpatient clinics in Sweden.

BACKGROUND: Missing diagnostic information often results poor accuracy of the clinical diagnostic decision process. The Mini International Neuropsychiatric Interview for Children and Adolescents (MINI-KID) is a short standardized diagnostic interview and covers a rather broad range of diagnoses applicable to children and adolescents. MINI-KID disorder classifications have shown test-retest reliability and validity comparable to other standardized diagnostic interviews and is claimed to be a useful tool for diagnostic screening in Child and Adolescent Psychiatric care. The concordance between the Swedish language version of the MINI-KID Interview and LEAD (Longitudinal, Expert, All Data) research diagnoses was studied in secondary child and adolescent psychiatric outpatient care. METHODS: MINI-KID interviews were performed for 101 patients, boys n = 50, girls n = 51, aged 4 to 18 years. The duration of the interview was on average 46 min, the child/adolescent participating together with the parent(s) in most cases. The seven most prevalent diagnoses were included in the analyses. RESULTS: The average overall percent agreement (OPA) between MINI-KID and LEAD was 79.5%, the average percent positive agreement (PPA) 35.4 and the average percent negative agreement (NPA) 92.7. OPA was highest for Obsessive-Compulsive Disorder (OCD) (0.89), Tic disorders (0.88) and Pervasive developmental disorders (0.81). There were similar results in diagnostic agreement comparing the two versions: the standard MINI-KID and MINI-KID for parents. The specific screening questions in MINI-KID resulted in additional preliminary diagnoses compared with the regular initial clinical assessment. CONCLUSIONS: Overall, there was an acceptable agreement between MINI-KID disorder classifications and research diagnoses according to LEAD. The standardized interview MINI-KID could be considered as a tool with the possibility to give valuable information in the diagnostic process in child and adolescent care which is similar to the setting in the present study.

Neurodevelopmental problems should be considered in children with febrile seizures.

AIM: Clinical developmental phenotyping of four- to five-year-old children with febrile seizures (FSs). METHODS: Children with FS (n = 157, corresponding to 3.7% of the targeted general population of four-five-year-olds) had been identified at child healthcare centres in Gothenburg. Parents of 73 children (41 boys, 32 girls) accepted participation in the present study. The assessments included a neuropaediatric assessment, Movement ABC, Wechsler Preschool and Primary Scale of Intelligence-III and parent questionnaires (Five-to-Fifteen (FTF) and Strengths and Difficulties Questionnaire (SDQ)). Hospital records were reviewed, when applicable. RESULTS: One-third of the children had at least one DSM-5 neurodevelopmental disorder diagnosis or marked developmental problems within areas of attention, activity regulation, behaviour, speech and language, general cognition or motor functioning. No differences were found between children with single vs recurrent or simple vs complex FS. CONCLUSION: Febrile seizure are relatively often associated with Early Symptomatic Syndromes Eliciting Neurodevelopmental Clinical Examinations (ESSENCEs). We found no indications that ESSENCE might be caused by FS per se. However, the results suggest that child healthcare professionals should consider the possibility of ESSENCE in children with a history of FS.

Gambling Disorder in Male Violent Offenders in the Prison System: Psychiatric and Substance-Related Comorbidity.

Gambling disorder is an addiction that can cause major suffering, and some populations seem to be more vulnerable than others. Offender populations have a remarkably high prevalence of gambling problems and they are also over-represented in a number of diagnoses related to gambling disorder, like substance use disorders and antisocial personality disorder. Yet, there are few studies investigating gambling disorder prevalence and related psychiatric comorbidity in this group. This study aims to investigate the prevalence of, and association between, gambling disorder and other psychiatric diagnoses in a sample of young, male violent offenders. Two hundred and sixty-four male offenders, all serving sentences for violent crimes (recruited between 2010 and 2012) participated in this study and went through comprehensive psychiatric evaluation, including assessment for Diagnostic and Statistical Manual of Mental Disorders 4th Edition criteria. Sixteen percent of the participants met criteria for gambling disorder. Antisocial personality disorder, cannabis, cocaine and anabolic steroids abuse were significantly more common among participants with gambling disorder. The gambling disorder group also showed significantly lower educational attainment. Cocaine abuse and failure to graduate elementary and middle school in expected time were independently associated with gambling disorder in a regression analysis. This study confirms the previously described high prevalence of gambling disorder in offenders. The psychiatric comorbidity was high and the problems had started early, with lower educational attainment in the gambling disorder group. The findings stress the importance of increased awareness of gambling problems among convicted offenders and of gambling research on young people with delinquent behavior. There is a need of more research to investigate this further, in order to develop preventive strategies and treatment.

Effect of visual stimuli of pain on empathy brain network in people with and without Autism Spectrum Disorder.

The extent to which affective empathy is impaired in Autism Spectrum Disorder (ASD) remains unclear, as some-but not all-previous neuroimaging studies investigating empathy for pain in ASD have shown similar activation levels to those of neurotypicals individuals. These inconsistent results could be due to the use of different empathy-eliciting stimuli. While some studies used pictures of faces exhibiting a painful expression, others used pictures of limbs in painful situations. In this study, we used fMRI to compare activation in areas associated with empathy processing (empathy network) for these two types of stimuli in 31 participants (16 with ASD, 15 controls). We found a group difference in the inferior frontal gyrus (IFG) and the thalamus when participants viewed stimuli of limbs in painful situations, but not when they viewed face stimuli with a painful expression. Both groups of participants activated their empathy network more when viewing pictures of limbs in painful situations than when viewing pictures of faces with a painful expression; this increased activation for limbs versus faces was significantly enhanced in controls relative to ASD participants, especially in the secondary somatosensory cortex (SII). Our findings suggest that empathy defect of people with ASD is contingent upon the type of stimuli used, and may be related to the level of Mirror Neuron System involvement, as brain regions showing group differences (IFG, SII) underlie embodiment. We discuss the potential clinical implications of our findings in terms of developing interventions boosting the empathetic abilities of people with ASD.

Hypersensitivity to low intensity fearful faces in autism when fixation is constrained to the eyes.

Previous studies that showed decreased brain activation in people with autism spectrum disorder (ASD) viewing expressive faces did not control that participants looked in the eyes. This is problematic because ASD is characterized by abnormal attention to the eyes. Here, we collected fMRI data from 48 participants (27 ASD) viewing pictures of neutral faces and faces expressing anger, happiness, and fear at low and high intensity, with a fixation cross between the eyes. Group differences in whole brain activity were examined for expressive faces at high and low intensity versus neutral faces. Group differences in neural activity were also investigated in regions of interest within the social brain, including the amygdala and the ventromedial prefrontal cortex (vmPFC). In response to low intensity fearful faces, ASD participants showed increased activation in the social brain regions, and decreased functional coupling between the amygdala and the vmPFC. This oversensitivity to low intensity fear coupled with a lack of emotional regulation capacity could indicate an excitatory/inhibitory imbalance in their socio-affective processing system. This may result in social disengagement and avoidance of eye-contact to handle feelings of strong emotional reaction. Our results also demonstrate the importance of careful control of gaze when investigating emotional processing in ASD. Hum Brain Mapp 38:5943-5957, 2017. © 2017 Wiley Periodicals, Inc.

Time Trends in Murray's Psychogenic Needs over Three Decades in Swedish 75-Year-Olds.

BACKGROUND: While time trends in personality traits have been suggested in younger cohorts, little is known regarding this issue in older adults. OBJECTIVE: To test for birth cohort changes in psychogenic needs according to Murray's theory of personality in two birth cohorts of 75-year-olds born 1901-1902 and 1930. METHODS: Two population-based birth cohorts were examined at the age of 75 years in 1976-1977 and in 2005-2006. Psychogenic needs according to Murray were measured with the Cesarec-Marke Personality Schedule (CMPS), a Swedish version of the Edwards Personal Preference Schedule. Scores on the CMPS subscales (achievement, affiliation, aggression, defence of status, guilt feelings, dominance, exhibition, autonomy, nurturance, order, succorance, and acquiescence) were compared between cohorts. RESULTS: Achievement, exhibition, dominance, aggression, affiliation, and succorance scores were higher, and order and acquiescence scores lower, in the more recent birth cohort of 75-year-olds. Women scored lower than men on exhibition and dominance, and higher on defence of status, guilt feelings, affiliation, nurturance, and succorance. Interaction effects between cohort and sex were found for achievement (women scored lower than men in 1976-1977 but not in 2005-2006), order (the lower scores in 2005-2006 were more accentuated among men), and acquiescence (increased in men and decreased in women). CONCLUSION: The later-born birth cohort scored higher on self-centred traits, such as more dominant, competitive, and exhibitive traits as well as the need to be taken care of and have friends around, but it scored lower on the need for order. The gap between men and women regarding achievement decreased, possibly reflecting women's more prominent role in society.

Anxiety and depression in adolescents with ADHD and autism spectrum disorders; correlation between parent- and self-reports and with attention and adaptive functioning.

BACKGROUND: Adolescents with attention-deficit/hyperactive disorder (ADHD) or autism spectrum disorder (ASD) are at high risk of anxiety and depression. This is important to identify in the clinical assessment to understand its impact. AIMS: The aim of this study is to investigate the correlation between parent- and self-reports of anxiety and depression in adolescents with ADHD or ASD, as well as the correlation with adaptive functioning and performance on an attention test. METHOD: A total of 65 adolescents with an ADHD diagnosis (n = 24) or an ASD diagnosis (n = 41) filled out Beck Youth Inventories of Emotional and Social Impairment (BYI) to assess depression and anxiety and completed a Continuous Performance Test (QbTest) measuring ADHD symptoms. Parents of the participants completed the internalizing domain in the Five to Fifteen questionnaire (FTF), measuring symptoms of anxiety and depression, and the Vineland Adaptive Behavior Scales (VABS) about the adolescent's adaptive functioning. RESULTS: Approximately a third of the study group self-reported substantial internalizing mental symptoms not always recognized by parents, and not always obvious in adaptive function or performance at ADHD test. Correlations between BYI and FTF were low. The BYI depression inventory correlated negatively with VABS and positively with activity level in a subgroup medicated for ADHD. There was a stronger correlation between girls BYI and FTF results as compared with boys. CONCLUSIONS: The results highlight the need for identification of anxiety and depression, using both self- and parent report. Present anxiety and depression symptoms do not seem to affect the clinical assessment of ASD and ADHD.

Offenders in emerging adulthood: School maladjustment, childhood adversities, and prediction of aggressive antisocial behaviors.

Early psychosocial adversities and maladjustment, such as childhood maltreatment and school adjustment problems, have been linked to an increased risk of aggressive antisocial behaviors. Yet, clinical studies of subjects at the highest risk of persistence in such behaviors are rare, especially during the life-changing transition years of emerging adulthood. This study describes early predictors of aggressive antisocial behaviors in a large, nationally representative cohort of Swedish, male violent offenders in emerging adulthood (age range = 18-25 years; N = 270). First, data on psychosocial background characteristics and aggressive antisocial behaviors (including age at onset) are provided. Second, early predictors of aggressive antisocial behaviors are tested in bivariate and multivariate interactive models. The offenders demonstrated a diversity of early onset adversities and disruptive behaviors, in line with established risk factors for subsequent criminality and adverse outcomes in a variety of life domains. Severe school adjustment problems, especially bullying others and early onset truancy, were important and interrelated predictors of aggressive antisocial behaviors over the lifetime, whereas childhood adversities such as parental substance or alcohol abuse and repeated exposure to violence at home during childhood were interrelated predictors of aggressive antisocial behaviors, albeit with less statistical importance. The findings stress the importance of early identification of individuals in the risk zone of developing severe and persistent aggressive antisocial behaviors and of early preventive interventions directed toward families with high-risk profiles. The findings also provide initial guidelines on which psychosocial background risk factors that need to be considered first-hand in early interventions. (PsycINFO Database Record

Asperger syndrome in males over two decades: stability and predictors of diagnosis.

OBJECTIVE: To examine the diagnostic stability of a childhood diagnosis of Asperger Syndrome (AS) into adulthood in a prospective longitudinal study, and identify the predictors of stability. METHODS: One hundred males with AS diagnosed in childhood (T0) according to Gillberg's AS criteria, were followed up prospectively into adulthood over an average of 19 years (range 13-26 years). Fifty males (mean age 30 years) participated in this second follow-up (T2) of the cohort. Seventy-six had participated in a previous follow-up (T1) at mean age 22 years (47 participated in both follow-ups). Diagnosis at T2 was assessed using three sets of diagnostic criteria (Gillberg's AS criteria, DSM-IV Pervasive Developmental Disorder (PDD) and DSM-5 Autism Spectrum Disorder (ASD) criteria) and compared to previous assessments. Background predictors of diagnostic stability were analyzed. General functioning at T2 was assessed and compared to T1. RESULTS: There was a decline in the stability of AS diagnosis over time, the rate dropping from 82% at T1 to 44% at T2, when using the Gillberg criteria. There was also a significant decrease in the rate of cases fulfilling any PDD diagnosis according to the DSM-IV, from 91% at T1 to 76% at T2 in the 47 cases followed up twice. Severity of autism spectrum symptoms at T1 was the main predictor of diagnostic stability at T2. Twenty percent of those meeting criteria for a PDD diagnosis according to DSM-IV, did not meet DSM-5 ASD criteria although they had marked difficulties in everyday life. CONCLUSION: Asperger Syndrome, when considered as an ASD/PDD diagnosis, was fairly stable into adulthood, but there was a significant increase over time in cases no longer meeting criteria for an ASD diagnosis according to the DSM-IV, or AS according to the Gillberg criteria. Cases with a stable diagnosis showed significantly more core ASD symptoms in adolescence/young adulthood.

Asperger syndrome and nonverbal learning difficulties in adult males: self- and parent-reported autism, attention and executive problems.

A specific overlap between Asperger syndrome (AS) and nonverbal learning difficulties (NLD) has been proposed, based on the observation that, as a group, people with AS tend to have significantly higher verbal IQ (VIQ) than performance IQ (PIQ), one of the core features of NLD. The primary aim was to assess the longer term outcome of NLD--broken down into persistent and transient forms. The present study of 68 individuals was performed in the context of a larger prospective longitudinal study to late adolescence/early adult life of 100 boys with AS. Using self- and parent-report measures, we studied the longer term outcome of the NLD (defined as VIQ > PIQ by 15 points) as regards social communication, repetitive behaviour, attention, and executive function (EF) was studied. Three subgroups were identified: (1) Persistent NLD (P-NLD), (2) Childhood "only" NLD (CO-NLD) and (3) Never NLD (NO-NLD). The P-NLD group had the worst outcome overall. The CO-NLD group had better reported EF scores than the two other AS subgroups. There were no differences between the subgroups regarding social communication, repetitive behaviour, or attentional skills. Low PIQ increased the risk of ADHD symptoms. In the context of AS in males, P-NLD carries a relatively poor outcome, particularly with regard to self-reported EF. However, CO-NLD appears to entail a significantly better outcome. The results underscore the importance of analysing the cognitive profile both at diagnosis and after several years, so as to be able to formulate a realistic prognosis.
