Pathways to professional mental care in the Swiss young adult community: a case-control study.

Treatment success for mental health (MH) problems depends, among others, on the timeliness of help-seeking. Therefore, we studied the effect of symptoms and reasons for help-seeking on the point-of-contact and the most intensive professional treatment in a community sample. Participants were recruited as part of the 'Bern Epidemiological At-Risk' (BEAR) study on 16-40-year-old community persons of the Swiss canton Bern. Of the 2,683 participants, 615 (22.9%) reported at least one instance of help-seeking for MH problems and were selected for the presented analyses. Help-seeking behavior was assessed by a modified version of the 'WHO pathway-to-care questionnaire', from which the outcome 'most intensive MH professional contact' was generated. The effect of symptoms and reasons for help-seeking were analyzed in separate models using path analyses. Most help-seeking persons sought MH professional help (n = 405; 65.9%) with a high number of medical pre-contacts (n = 233; 37.9%). The 'most intensive MH professional contact' was provided after an average of 1.47 contacts. Both models showed negative associations between non-MH professional pre-contacts and the most intensive, likely most adequate MH treatment. In the symptom model, 'substance misuse' and 'central-vegetative problems' increased the general likelihood of MH professional contact. Our findings highlight the importance of the first point-of-contact in pathways to adequate MH care and, when seeking help from non-MH professional, of quick referrals to MH professionals. Awareness campaigns or training of health professionals, such as general practitioners, may support timely contact with MH professionals to improve diagnosis, prognosis, and outcome.

Influence of mental health literacy on help-seeking behaviour for mental health problems in the Swiss young adult community: a cohort and longitudinal case-control study.

Poor knowledge about mental health disorders and their treatment likely contributes to the large treatment gap reported for mental health problems. Therefore, we studied the association between mental health literacy (MHL) and active help-seeking in a community sample. Participants were recruited from an add-on questionnaire study to the 'Bern Epidemiological At-Risk' (BEAR) study on 16-40-year-old community subjects of the Swiss canton Bern. At baseline, data of N = 1504, and at 3-year follow-up, data of N = 535 were available. Based on an unlabelled case vignette (on depression or schizophrenia), MHL was assessed by the questionnaire of Angermeyer and colleagues. Cross-sectional and longitudinal baseline predictors of help-seeking were analysed using path analyses. Additionally, sensitivity analyses of the prospective model were computed for sex, vignette, and baseline mental health problems/disorders. Cross-sectionally, help-seeking was associated with non-endorsement of biogenetic causal explanations, presence of mental health problems/disorders, help-seeking before baseline, poorer functioning, and lower health satisfaction. The prospective model was similar; yet, help-seeking at follow-up was associated with endorsements of the causal explanation 'biogenetics' and, additionally, 'childhood trauma' but not the presence of baseline mental health problems/disorders. Sensitivity analyses revealed a significant impact on sex, vignette, and mental health problems/disorders. For example, actual functional problems were predictive in males, while health satisfaction was predictive in females. Our findings indicate that future studies on drivers of help-seeking should assess very large community samples with case vignettes on different mental disorders to examine appropriate subgroups and their likely interaction to address group-specific factors in awareness campaigns.

Oxytocin and cortisol concentrations in adults with and without autism spectrum disorder in response to physical exercise.

Autism spectrum disorder (ASD) is a neurodevelopmental disorder, whose core symptoms consist of deficits in social interaction and communication as well as restricted and repetitive behavior. Brain oxytocin (OXT) has been associated with various prosocial behaviors, and might, therefore, be involved in the pathogenesis of disorders associated with socio-emotional dysfunctions such as ASD. However, significant associations between central and peripheral OXT levels may only be present in response to physiological or stressful stimuli but were not shown under baseline conditions. In this study, we, therefore, investigated salivary and plasma OXT in response to physical exercise in adults with ASD (n â€‹= â€‹33, mean age: 36.8 â€‹± â€‹10.7 years) without intellectual impairment (IQ â€‹> â€‹70) and neurotypical controls (n â€‹= â€‹31, mean age: 31.0 â€‹± â€‹11.7 years). To stimulate the OXT system, we used rapid cycling and measured cortisol (CORT) concentrations to monitor the physiological stress response. When controlling for age, neither salivary OXT (p â€‹= â€‹.469), plasma OXT (p â€‹= â€‹.297) nor CORT (p â€‹= â€‹.667) concentrations significantly differed between groups at baseline. In addition, neither OXT nor CORT concentrations significantly differed between groups after physical exercise. Social anxiety traits were negatively correlated with plasma, but not saliva OXT concentrations in neurotypicals at baseline, while empathetic traits were positively correlated with saliva, but not plasma concentrations in autistic patients at baseline. No significant correlations between salivary and plasma OXT concentrations were found at any time point. Future studies including adult participants should investigate the effect of age on CORT and OXT concentrations in response to stress.

Young adolescents with autism show abnormal joint attention network: A gaze contingent fMRI study.

Behavioral research has revealed deficits in the development of joint attention (JA) as one of the earliest signs of autism. While the neural basis of JA has been studied predominantly in adults, we recently demonstrated a protracted development of the brain networks supporting JA in typically developing children and adolescents. The present eye-tracking/fMRI study now extends these findings to adolescents with autism. Our results show that in adolescents with autism JA is subserved by abnormal activation patterns in brain areas related to social cognition abnormalities which are at the core of ASD including the STS and TPJ, despite behavioral maturation with no behavioral differences. Furthermore, in the autism group we observed increased neural activity in a network of social and emotional processing areas during interactions with their mother. Moreover, data indicated that less severely affected individuals with autism showed higher frontal activation associated with self-initiated interactions. Taken together, this study provides first-time data of JA in children/adolescents with autism incorporating the interactive character of JA, its reciprocity and motivational aspects. The observed functional differences in adolescents ASD suggest that persistent developmental differences in the neural processes underlying JA contribute to social interaction difficulties in ASD.

Interpersonal predictive coding, not action perception, is impaired in autism.

This study was conducted to examine interpersonal predictive coding in individuals with high-functioning autism (HFA). Healthy and HFA participants observed point-light displays of two agents (A and B) performing separate actions. In the 'communicative' condition, the action performed by agent B responded to a communicative gesture performed by agent A. In the 'individual' condition, agent A's communicative action was substituted by a non-communicative action. Using a simultaneous masking-detection task, we demonstrate that observing agent A's communicative gesture enhanced visual discrimination of agent B for healthy controls, but not for participants with HFA. These results were not explained by differences in attentional factors as measured via eye-tracking, or by differences in the recognition of the point-light actions employed. Our findings, therefore, suggest that individuals with HFA are impaired in the use of social information to predict others' actions and provide behavioural evidence that such deficits could be closely related to impairments of predictive coding.

Look into my eyes: Investigating joint attention using interactive eye-tracking and fMRI in a developmental sample.

Joint attention, the shared attentional focus of at least two people on a third significant object, is one of the earliest steps in social development and an essential aspect of reciprocal interaction. However, the neural basis of joint attention (JA) in the course of development is completely unknown. The present study made use of an interactive eye-tracking paradigm in order to examine the developmental trajectories of JA and the influence of a familiar interaction partner during the social encounter. Our results show that across children and adolescents JA elicits a similar network of "social brain" areas as well as attention and motor control associated areas as in adults. While other-initiated JA particularly recruited visual, attention and social processing areas, self-initiated JA specifically activated areas related to social cognition, decision-making, emotions and motivational/reward processes highlighting the rewarding character of self-initiated JA. Activation was further enhanced during self-initiated JA with a familiar interaction partner. With respect to developmental effects, activation of the precuneus declined from childhood to adolescence and additionally shifted from a general involvement in JA towards a more specific involvement for self-initiated JA. Similarly, the temporoparietal junction (TPJ) was broadly involved in JA in children and more specialized for self-initiated JA in adolescents. Taken together, this study provides first-time data on the developmental trajectories of JA and the effect of a familiar interaction partner incorporating the interactive character of JA, its reciprocity and motivational aspects.

Transdiagnostic commonalities and differences in resting state functional connectivity of the default mode network in schizophrenia and major depression.

Schizophrenia and depression are prevalent psychiatric disorders, but their underlying neural bases remains poorly understood. Neuroimaging evidence has pointed towards the relevance of functional connectivity aberrations in default mode network (DMN) hubs, dorso-medial prefrontal cortex and precuneus, in both disorders, but commonalities and differences in resting state functional connectivity of those two regions across disorders has not been formally assessed. Here, we took a transdiagnostic approach to investigate resting state functional connectivity of those two regions in 75 patients with schizophrenia and 82 controls from 4 scanning sites and 102 patients with depression and 106 controls from 3 sites. Our results demonstrate common dysconnectivity patterns as indexed by a significant reduction of functional connectivity between precuneus and bilateral superior parietal lobe in schizophrenia and depression. Furthermore, our findings highlight diagnosis-specific connectivity reductions of the parietal operculum in schizophrenia relative to depression. In light of evidence that points towards the importance of the DMN for social cognitive abilities and well documented impairments of social interaction in both patient groups, it is conceivable that the observed transdiagnostic connectivity alterations may contribute to interpersonal difficulties, but this could not be assessed directly in our study as measures of social behavior were not available. Given the operculum's role in somatosensory integration, diagnosis-specific connectivity reductions may indicate a pathophysiological mechanism for basic self-disturbances that is characteristic of schizophrenia, but not depression.

Attenuated prefrontal activation during decision-making under uncertainty in schizophrenia: a multi-center fMRI study.

Decisions are called decisions under uncertainty when either prior information is incomplete or the outcomes of the decision are unclear. Alterations in these processes related to decisions under uncertainty have been linked to delusions. In patients with schizophrenia, the underlying neural networks have only rarely been studied. We aimed to disentangle the neural correlates of decision-making and relate them to neuropsychological and psychopathological parameters in a large sample of patients with schizophrenia and healthy subjects. Fifty-seven patients and fifty-seven healthy volunteers from six centers had to either indicate via button-press from which of two bottles red or blue balls were drawn (decision-making under uncertainty condition), or indicate whether eight red balls had been presented (baseline condition) while BOLD signal was measured with fMRI. Patients based their decisions on less conclusive evidence and had decreased activations in the underlying neural network, comprising of medial and lateral frontal as well as parietal areas, as compared to healthy subjects. While current psychopathology was not correlated with brain activation, positive symptoms led to longer decision latencies in patients. These results suggest that decision-making under uncertainty in schizophrenia is affected by a complex interplay of aberrant neural activation. Furthermore, reduced neuropsychological functioning in patients was related to impaired decision-making and task performance was modulated by distinct positive symptoms.

Investigation of decision-making under uncertainty in healthy subjects: a multi-centric fMRI study.

Decision-making is an everyday routine that entails several subprocesses. Decisions under uncertainty occur when either prior information is incomplete or the outcomes of the decision are unclear. The aim of the present study was to disentangle the neural correlates of information gathering as well as reaching a decision and to explore effects of uncertainty acceptance or avoidance in a large sample of healthy subjects. Sixty-four healthy volunteers performed a decision-making under uncertainty task in a multi-center approach while BOLD signal was measured with fMRI. Subjects either had to indicate via button press from which of two bottles red or blue balls were drawn (decision-making under uncertainty condition), or they had to indicate whether 8 red balls had been presented (baseline condition). During the information gathering phase (contrasted against the counting phase) a widespread network was found encompassing (pre-)frontal, inferior temporal and inferior parietal cortices. Reaching a decision was correlated with activations in the medial frontal cortex as well as the posterior cingulate and the precuneus. Effects of uncertainty acceptance were found within a network comprising of the superior frontal cortex as well as the insula and precuneus while uncertainty avoidance was correlated with activations in the right middle frontal cortex. The results depict two distinct networks for information gathering and the indication of having made a decision. While information-gathering networks are modulated by uncertainty avoidance and - acceptance, underlying networks of the decision itself are independent of these factors.

Neural correlates of "social gaze" processing in high-functioning autism under systematic variation of gaze duration.

Direct gaze is a salient nonverbal signal for social interest and the intention to communicate. In particular, the duration of another's direct gaze can modulate our perception of the social meaning of gaze cues. However, both poor eye contact and deficits in social cognitive processing of gaze are specific diagnostic features of autism. Therefore, investigating neural mechanisms of gaze may provide key insights into the neural mechanisms related to autistic symptoms. Employing functional magnetic resonance imaging (fMRI) and a parametric design, we investigated the neural correlates of the influence of gaze direction and gaze duration on person perception in individuals with high-functioning autism (HFA) and a matched control group. For this purpose, dynamically animated faces of virtual characters, displaying averted or direct gaze of different durations (1 s, 2.5 s and 4 s) were evaluated on a four-point likeability scale. Behavioral results revealed that HFA participants showed no significant difference in likeability ratings depending on gaze duration, while the control group rated the virtual characters as increasingly likeable with increasing gaze duration. On the neural level, direct gaze and increasing direct gaze duration recruit regions of the social neural network (SNN) in control participants, indicating the processing of social salience and a perceived communicative intent. In participants with HFA however, regions of the social neural network were more engaged by averted and decreasing amounts of gaze, while the neural response for processing direct gaze in HFA was not suggestive of any social information processing.

To you I am listening: perceived competence of advisors influences judgment and decision-making via recruitment of the amygdala.

Considering advice from others is a pervasive element of human social life. We used the judge-advisor paradigm to investigate the neural correlates of advice evaluation and advice integration by means of functional magnetic resonance imaging. Our results demonstrate that evaluating advice recruits the "mentalizing network," brain regions activated when people think about others' mental states. Important activation differences exist, however, depending upon the perceived competence of the advisor. Consistently, additional analyses demonstrate that integrating others' advice, i.e., how much participants actually adjust their initial estimate, correlates with neural activity in the centromedial amygdala in the case of a competent and with activity in visual cortex in the case of an incompetent advisor. Taken together, our findings, therefore, demonstrate that advice evaluation and integration rely on dissociable neural mechanisms and that significant differences exist depending upon the advisor's reputation, which suggests different modes of processing advice depending upon the perceived competence of the advisor.

Pharmacological treatment of deep brain stimulation-induced hypomania leads to clinical remission while preserving motor benefits.

Deep brain stimulation (DBS) of the subthalamic nucleus (STN) is an effective treatment for Parkinson's disease, but can lead to adverse effects including psychiatric disturbance. Little is known about the risk factors and treatment options for such effects. Here, we describe a patient who reproducibly developed stimulation-induced hypomania when using ventrally located electrodes and responded well to pharmacological intervention while leaving the stimulation parameters unchanged to preserve motor benefits. In spite of clinical remission, [¹5O]-positron-emission-tomography (PET) demonstrated activation patterns similar to those reported during mania. This case, therefore, highlights an important treatment option of adverse effects of DBS, but also points toward the need for investigations of its risk factors and their underlying neurobiological mechanisms.

[Psychosocial functioning of adults with late diagnosed autism spectrum disorders--a retrospective study]. / Das psychosoziale Funktionsniveau spätdiagnostizierter Patienten mit Autismus-Spektrum-Störungen--eine retrospektive Untersuchung im Erwachsenenalter.

BACKGROUND: The first time diagnosis of autism spectrum disorder (ASD) after passing childhood and adolescence is still considered a rare event. However, in recent years an increasing demand for diagnostic clarifications with suspected ASD in adulthood challenges this view. There is insufficient knowledge about the neuropsychological characterisation and psychosocial outcome of this adult subgroup in the autistic spectrum. AIM: To determine the psychosocial functioning (living status, partnerships, level of education, psychiatric history) of adult patients with late diagnosed ASD. METHODS: In a retrospective study, a chart review was conducted on 178 consecutively diagnosed individuals at a specialised outpatient clinic for adults with ASD. Global ratings of psychosocial functioning, assessment of psychiatric history and neuropsychological and psychopathological investigations were evaluated. RESULTS: The majority of patients (92 %) diagnosed with ASD suffered from high-functioning autism (HFA)/Asperger syndrome (AS) according to the criteria of ICD-10 (F84.5). The gender ratio was 2:1 favouring males. Mean age at diagnosis (34.1 ± 9.5 years), general intelligence (HAWIE-R, global-IQ 115 ± 20) and self-rated autistic symptoms (autism spectrum quotient [AQ] 39 ± 6) were not discriminative to gender. The psychiatric history revealed a lifetime consultation rate of 78 %, most frequently with depression (50 %). The self-report instrument Beck depression inventory (BDI) identified 30 % of individuals presenting with depressive symptoms in clinical relevant intensity (BDI > 17). Achievement of an independent living status was reported by 68 % of individuals, 58 % reported about current or past intimate partnerships and almost two-thirds of the patients had achieved a higher educational status. DISCUSSION: The majority of ASD diagnosed late in lifetime turned out to be HFA/AS, presenting with high psychosocial adjustment with regard to independent living, educational status and partnerships. The high level of global intelligence supports the hypothesis of cognitively compensated autistic disturbances leading to the diagnosis comparably late in lifetime. The lifetime rate of psychiatric consultations is high, reflecting the importance to consider a diagnosis of ASD even late in life.

[Expectations concerning psychotherapy of high-functioning adults with autism spectrum disorders]. / Erwartungen an eine Psychotherapie von hochfunktionalen erwachsenen Personen mit einer Autismus-Spektrum-Störung.

BACKGROUND: In recent years there has been a strong increase in psychiatric diagnoses belonging to the autism spectrum in adulthood. For this diagnostic group of patients, often characterised by normal or above-average intelligence, i.e, high-functioning autism or Asperger syndrome, only few adequate psychotherapeutic treatment options exist. In order to develop a disorder-specific psychotherapeutic group training in a demand-oriented manner, we surveyed adults with autism spectrum disorders (ASD) concerning their needs and expectations relating to psychotherapy. METHODS: A two-step analysis of needs was carried out: First, after a set of open questions written descriptions of 33 individuals with ASD were analysed using the qualitative content analysis according to Mayring. The resulting category system provided the basis for the closed questionnaire EPAS ("Expectations Psychotherapy Autism Spectrum"). In a second step, 64 individuals with ASD were assessed by EPAS to confirm the relevance of the qualitatively derived dimensions. RESULTS: Both the results of the qualitative and the quantitative analysis confirmed the initial hypothesis that adults with ASD expressed problems associated with disorder-specific core symptoms. Moreover, the quantitative analysis demonstrated that in addition to deficits in social competence and identity formation, the lack of stress management skills represents a crucial load factor. Also, the therapist-associated variables were reported to play an important role for the patients. DISCUSSION: The analysis of needs indicates that psychotherapy for adults with ASD should focus on the training and development of social-communicative skills. Furthermore, dealing with stress in everyday situations and identity formation after diagnosis should also be considered. Psychotherapists can refer to well-established techniques from cognitive behavioural therapy, which are known to be effective in the identified fields and should have sufficient disorder-specific knowledge, not least in order to prevent misunderstandings within the therapeutic working relationship.

[Autism spectrum disorders in adulthood: clinical and neuropsychological findings of Aspergers syndrome diagnosed late in life]. / Autismus-Spektrum-Störungen im Erwachsenenalter: Klinische und Neuropsychologische Befunde Spätdiagnostizierter Asperger-Syndrome.

INTRODUCTION: High-functioning autism (HFA) and Aspergers syndrome (AS) are autism spectrum disorders (ASD) characterised by disturbances in social interaction, both verbal and non-verbal communication and repetitive and/or restrictive behaviour since early childhood. Symptoms appear generally during early childhood and adolescence. The increasing need to clarify diagnostic queries in advanced age led to the constitution of specialised outpatient clinics for adults involving a growing amount of HFA/AS subjects diagnosed late in life. However, thus far neuropsychological data about this group are scarce. METHODS: We present a subgroup of 39 patients with HFA/AS (mean age at diagnosis 31.1 ± 8.9 years) who were consecutively diagnosed at the autism outpatient clinic at the Department of Psychiatry at the University Hospital Cologne. Autistic symptoms (autism spectrum quotient; AQ), depressive symptoms (Beck depression inventory; BDI), general intelligence (HAWIE-R), social cognition ("theory of mind", ToM) and executive functioning (COWAT) were systematically studied in comparison to a control group matched for age, education, gender and intelligence (n = 39). RESULTS: HFA/AS subjects presented higher AQ scores (40.4 ± 5.2) as opposed to the healthy controls (13.5 ± 4.8). Neuropsychologically, patients showed deficits in social cognition, executive functions and in subtests of HAWIE-R related to verbal comprehension and perceptual organisation as opposed to the healthy control group. DISCUSSION: The diagnosis of autistic disorders in adulthood basically relies on the clinical assessment of autistic core symptoms which were corroborated by high AQ values. The self-rating instrument AQ was found to be highly discriminative between the HFA/AS group and the healthy control group. The neuropsychological profile of adult HFA/AS patients diagnosed late in life is compatible with that of previously investigated HFA/AS populations. These findings show that such basic autism-associated deficits persist until adulthood, although patients are able to learn social rules.
