Psychiatric symptoms have been reported quite frequently in certain thyroid diseases, but more frequently in association with hypothyroidism. Thyrotoxicosis can be associated with various psychiatric symptoms, such as emotional lability, anxiety, restlessness and rarely frank psychosis. Psychotic symptoms in the context of hyperthyroidism typically present as an affective psychosis. The link between psychosis and hyperthyroidism is poorly understood. Because of this association of psychiatric symptoms is important to exclude a somatic cause, when assessing a patient first. We present the case of young woman who was followed over 2 years and who initially presented to psychiatric consultation for depressive symptoms, after being diagnosed with hyperthyroidism and specific therapy instituted, but who developed psychotic symptoms.

Background. Atypical antipsychotics proved efficacy in monotherapy and more so in association with mood stabilizers, but choosing the atypical antipsychotic requires special cautions due to metabolic adverse effects. The aim: to verify if Quetiapine-valproate combination improves rapidly acute depressive symptoms and has a good endocrinemetabolic tolerability. Case presentation. A 49 years male, bipolar patient, admitted for a major depressive episode. The patient also has type 2 DM for which he takes oral antidiabetics. When inpatient, he had persistent hyperglycemia (>250mg/dL). DM's complications (poly-neuropathy, retinopathy and right bundle-branch block). Diabetic status oriented us to choose quetiapine (600 mg/day) for both antidepressive effect and its safe metabolic profile associated with valproate (1000 mg/day). Antidiabetic medication was adjusted following the clinical outcome. Instruments. for depression we used Montgomery- Asberg Rating Scale (MARS), for mania Young Mania Rating Scale (YMRS), Clinical Global Impression for Bipolar Disorder (CGI-BP), for diabetes (glycemia, HbA1c, glycosuria, body weight, adverse events and relapse were followed-up for 6 months. The evaluations were performed weekly during hospitalization (6 weeks) and then monthly, for 6 months quetiapine together with valproate therapy led to remission of depressive symptoms (MADRS <50% vs. baseline). At the same time DM was compensated with glimpirid and metformin (glycemia < 120mg/dL). These results maintained till the end of the follow-up period. Conclusion. Quetiapine associated to valproate in acute and chronic management of bipolar depression proved to be efficient and well tolerated, along 6 months, in patient with type 2 diabetes.

- Abstract
Background: There is a lack of studies examining psychosocial functioning in patients with non-suicidal self-injury (NSSI), especially in adolescents, and rates of impaired functioning in existing literature vary considerably. These variations may be attributable to further risk factors that influence psychosocial functioning. Thus, the aim of the study was to examine whether adolescent NSSI patients with childhood maltreatment (CM), a known risk factor for lower psychosocial functioning, may differ from adolescent NSSI patients without CM, and whether these differences may be explained by the severity of comorbid disorders. Specifically, we examined whether severity of borderline personality disorder (BPD), depression and posttraumatic stress disorder may explain differences in psychosocial functioning in NSSI patients with and without CM., Methods: Data of 368 adolescents with NSSI disorder from an outpatient clinic were analyzed using structural equation modeling. Clinicans' rating of the Global Assessment of Functioning Scale (GAF) was collected, in addition to clinical interviews., Results: Results indicate that GAF scores were lower among NSSI patients with CM and that the difference in psychosocial functioning between these groups was explained by BPD and depression severity., Conclusions: Psychosocial functioning in NSSI patients varies depending on whether they have experienced CM or not. Specifically, these differences seem to be attributable to higher BPD and depression severity in adolescent NSSI patients with CM. Clinicians should ensure to assess CM and focus on BPD and depression severity in this population. Treatment of BPD and depression may notably reduce psychosocial impairment in NSSI patients with CM.

- Abstract
Background: Predicting suicide attempts is a challenging task for clinicians and researchers, particularly among high-risk individuals (i.e. adolescents with lifetime suicide attempts). In this study, we examined whether adolescents were able to predict their own risk of attempting suicide in the future and whether borderline personality disorder (BPD) or depressive symptoms impacted the predictive value of self-ratings., Methods: Structured clinical assessments were conducted at baseline and after 12 months in a high-risk sample of treatment-seeking adolescents (n = 134; 12-17y.; 90% female) with at least one lifetime suicide attempt., Results: During the follow-up period, n = 51 participants (38%) attempted suicide at least once. Self-rated risk was a significant predictor for the recurrence of a suicide attempt, whereas BPD and depression were not. While there was no significant interaction between self-rated risk and BPD, a negative interaction emerged between self-rated risk and depression in the prediction of a suicide attempt. Greater depression severity diminished the predictive value of self-ratings., Limitations: Depression severity was measured using a questionnaire, not a clinical interview. The findings may not be applicable to less burdened samples., Conclusions: Asking high-risk adolescents to rate their own risk of attempting suicide appears to be an easy to apply method in improving the prediction of future suicide attempts in the clinical context., (Copyright © 2020.

- Abstract
Background: The heterogeneous presentation of borderline personality disorder (BPD) represents a clinical challenge. There is an ongoing scientific debate whether the heterogeneity can best be understood in terms of qualitative (categorical) or quantitative (dimensional) differences between individuals. The present study examined the latent structure of BPD in adolescents., Methods: Five-hundred and six outpatients aged 12 to 17 years with risk-taking and/or self-harming behavior were assessed at baseline and one-year follow-up. Latent class analysis (corresponding with the categorical approach), factor analysis (corresponding with the dimensional approach), and factor mixture models (allowing for both categorical and dimensional aspects) were applied to the DSM-IV BPD criteria., Results: The best fitting model distinguished between a majority class with high probabilities for all BPD criteria ("borderline group") and a minority class with high probabilities for the impulsivity and anger criteria only ("impulsive group"). Sex significantly affected latent class membership, and both a latent factor and age explained within-class variability. The borderline group primarily consisted of females, frequently reported adverse childhood experiences, scored high on the emotion dysregulation and inhibitedness personality traits, and was associated with internalizing psychopathology. In contrast, the impulsive group primarily consisted of males, scored high on the dissocial behavior personality trait, and was associated with externalizing psychopathology. After one year, the two groups showed similar clinical improvement., Conclusions: The study provides evidence for two distinct subgroups of adolescents with BPD features that resemble the subtypes of the ICD-10 emotionally unstable personality disorder. More research is needed to further investigate the diagnostic stability of the two groups over time and potential differential treatment indications.

- Abstract
Background: With inclusion of non-suicidal self-injury disorder (NSSID) in the DSM-5, empirical data are crucial to gather information regarding its clinical validity and relevance. Until now, research focused mostly on single diagnostic criteria of NSSID. The present study aimed to characterize NSSID with and without comorbid diagnoses in a large help-seeking adolescent sample, investigating the clinical validity and selectivity of NSSID within the theoretical framework of Robins and Guze., Methods: Interview and self-report data of n = 464 adolescents (mean age = 14.95 years, SD = 1.43, 89.17% female) with NSSID according to DSM-5 from a German outpatient clinic were analysed with descriptive statistics. Group differences were calculated with χ
2 tests or t-tests respectively. Stability of NSSID without comorbidity was investigated after 12 months., Results: Within a consecutive help-seeking sample, NSSID as a stand-alone diagnosis (without comorbidity) was rare (only 3.7%), associated with low illness severity and psychopathological distress, and prospectively rather unstable., Limitation: Selection bias due to the help-seeking population and female preponderance., Conclusion: Based on the theoretical framework applied, NSSI should be considered as an unspecific precursor for psychopathological development generally and suicide specifically but it may be of limited significance as a 'pure and sole' diagnostic entity. Results add to existing claims to re-propose classification criteria to better picture the clinical group of affected adolescents., Competing Interests: Declaration of Competing Interest The authors were independent of the funders in all aspects of study design, data analysis, and writing of this manuscript and have no conflict of interest to declare., (Copyright © 2020 The Authors.

- Abstract
The Association Between Illicit Drug Use, Borderline Personality Disorder and Depression in a Help-Seeking Sample of Adolescents Risk-taking behavior is a common phenomenon in adolescence. Even prevalence rates for illicit drug use are considerably high in youth and associated with a range of psychiatric disorders, especially depression and Borderline Personality Disorder (BPD). However, there is a lack of data investigating differences in psychopathology between different substance user groups. Therefore, aim of the study was to investigate occurrence of depression and BPD symptoms in different drug risk groups (no use vs. occasional use vs. frequent use). Further aim of the study was to examine risk profiles regarding single BPD criteria. Data of n = 347 adolescents (81.7 % female, mean age 14.95, SD = 1.50) presenting at the specialized outpatient clinic for risk-taking and self-harming behavior (AtR!Sk) in Heidelberg were analyzed. Results show that BPD is clearly associated with illicit drug use in adolescence. There is no difference between occasional and frequent users in terms of mean number of BPD criteria. However, frequent users differ from occasional users regarding greater number of impulsivity and anger criteria. After adjusting for sociodemographic variables there was no association between drug use and depression. Since even single events of illicit drug use are associated with higher levels of BPD, clinicians should rapidly target to stop consumption. Further, psychotherapeutic interventions for BPD in high-risk consumers should especially focus on facilitating adaptive emotion regulation skills in regards to impulsivity and anger.

- Abstract
Self-injurious behavior and risk-taking behaviors are associated with adolescent borderline personality disorder (BPD). Developmental trajectories of self-injurious and risk-taking behavior in predicting BPD have not been fully understood. The aim of the present study was to examine self-injurious and risk-taking behavior development and their prospective influence on BPD symptoms in adolescence. Data (n = 506; 62.06 % females, 14.53 years) from the German Saving and Empowering Young Lives in Europe cohort were analyzed. Self-injurious and risk-taking behaviors were assessed at baseline and one-year follow-up. BPD symptoms were assessed at two-year follow-up. In fully adjusted stepwise binominal regression analyses, recent onset, termination and maintenance of risky alcohol use and self-injurious behavior remained as significant predictors of BPD. Highest ORs were found for alcohol termination and maintenance of self-injurious behavior. Other facets of risk-taking behavior were not associated with increased ORs of BPD symptoms at two-year follow-up. These findings highlight the importance of self-injurious behavior and specific facets of risk-taking behavior in the development of adolescent BPD. Clinicians should focus on efforts in preventing adolescents from risk-taking and self-injurious behavior, since engaging in young age and therefore in potentially longer periods of these behaviors is associated with the highest risk of BPD., (Copyright © 2019 Elsevier B.V.

- Abstract
Memory impairments are a major characteristic of schizophrenia (SZ). In the current study, we used an associative memory task to test the hypothesis that SZ patients and first-degree relatives have altered functional patterns in comparison to healthy controls. We analyzed the fMRI activation pattern during the presentation of a face-name task in 27 SZ patients, 23 first-degree relatives, and 27 healthy controls. In addition, we performed correlation analyses between individual psychopathology, accuracy and reaction time of the task and the beta scores of the functional brain activations. We observed a lower response accuracy and increased reaction time during the retrieval of face-name pairs in SZ patients compared with controls. Deficient performance was accompanied by abnormal functional activation patterns predominantly in DMN regions during encoding and retrieval. No significant correlation between individual psychopathology and neuronal activation during encoding or retrieval of face-name pairs was observed. Findings of first-degree relatives indicated slightly different functional pattern within brain networks in contrast to controls without significant differences in the behavioral task. Both the accuracy of memory performance as well as the functional activation pattern during retrieval revealed alterations in SZ patients, and, to a lesser degree, in relatives. The results are of potential relevance for integration within a comprehensive model of memory function in SZ. The development of a neurophysiological model of cognition in psychosis may help to clarify and improve therapeutic options to improve memory and functioning in the illness.

- Abstract
Background: Working memory (WM) deficits in schizophrenia (SCZ) have been linked to impairments in the encoding phase that are associated with aberrant neuronal functioning. Similar abnormalities have been observed in unaffected first-degree relatives (REL) and are thus discussed as candidate endophenotypes. The process of WM consolidation - i.e. the formation of durable WM representations - is assumed to be impaired in SCZ, but no study has investigated WM consolidation and neuronal correlates of visual WM encoding in REL before., Method: We examined whole-brain activation during the encoding phase with an event-related functional magnetic resonance imaging study design in 25 SCZ subjects, 22 REL subjects, and 25 healthy controls. Subjects performed a visual masked change detection task that assessed WM performance and consolidation., Results: SCZ showed deficient WM performance indicating an impairment consolidation process, accompanied by broad neuronal hypoactivation, most prominently in frontal brain regions, as well as increased activity of the anterior cingulate during the encoding phase. REL showed decreased neuronal activity in the middle and medial frontal gyrus and increased activity in the precentral gyrus and insula during encoding, but no significant behavioral deficits were observed. In respect of given consolidation times, REL showed a shift from decreased frontal activity at short time intervals to increased frontal activity at longer time intervals., Conclusions: Findings suggest WM consolidation may be slowed in REL so that the deployment of compensatory neuronal resources during encoding is needed to assure proper WM performance. This supports the view of WM-related neuronal dysfunctions as a potential endophenotypic marker.

- Abstract
The Outpatient Clinic for Adolescent Risk-taking and Self-harm behaviors (AtR!Sk) - A Pioneering Approach of Outpatient Early Detection and Intervention of Borderline Personality Disorder Self-harm and risk-taking behaviors are frequently occurring problems in adolescents' everyday life and commonly challenge the present child and adolescent health-care system. Those behaviors are typical features of borderline-personality disorder (BPD), a severe mental disorder that is associated with immense psychological strain, increased risk of mortality and poor psychosocial functioning. Despite controversy in the past, recent evidence shows that BPD is a valid and reliable diagnosis in adolescence. Consequently, specified and effective intervention programs for this age group are necessary. Instead, present health-care services for children and adolescents in Germany are usually characterized by long waiting periods for specialized outpatient treatments and unnecessary expanses of unnecessary long inpatient stays. Alternatively, and in order to prevent serious long-term consequences, new concepts - integrated in an ambulatory setting and close to patients' daily routines - should focus on early detection and treatment of adolescents at-risk presenting with borderline personality features. The specialist outpatient clinic AtR!Sk at the University Hospital Heidelberg ensures a low-threshold initial contact service, comprehensive and accurate diagnosis of BPD features, and rapidly "tailored" therapy for young people presenting with any types of risk-taking and self-harm behavior. AtR!Sk - as a pioneering approach in south Germany - provides evidence-based early detection and intervention for adolescent BPD.

- Abstract
Objective: Working memory (WM) impairments are a prominent neurocognitive symptom in schizophrenia (SZ) and include deficits in memory for serial order and abnormalities in serial position effects (i.e., primacy and recency effects). Former studies predominantly focused on investigating these deficits applying verbal or static visual stimuli, but little is known about WM processes that involve dynamic visual movements. We examined WM for visual motion directions, its susceptibility to distraction and the effect of serial positioning., Method: Twenty-three patients with paranoid SZ and 23 healthy control subjects (HC) took part in the study. We conducted an adapted Sternberg-type recognition paradigm: three random dot kinematograms (RDKs) that depicted coherent visual motion were used as stimuli and a distractor stimulus was incorporated into the task., Results: SZ patients performed significantly worse in the WM visual motion task, when a distractor stimulus was presented. While HC showed a recency effect for later RDKs, the effect was absent in SZ patients. WM deficits were associated with more severe psychopathological symptoms, poor visual and verbal learning, and a longer duration of illness. Furthermore, SZ patients showed impairments in several other neurocognitive domains., Conclusions: Findings suggest that early WM processing of visual motion is susceptible to interruption and that WM impairments are associated with clinical symptoms in SZ. The absence of a recency effect is discussed in respect of 3 theoretical approaches-impaired WM for serial order information, abnormalities in early visual representations (i.e., masking effects), and deficits in later visual processing (i.e., attentional blink effect).

- Abstract
Cognitive impairments have been linked to structural and functional alterations in frontal and subcortical brain regions, ultimately leading to fronto-thalamic connectivity disturbances. We hypothesized that such neuronal disruptions in frontal and subcortical structures may account for neuropsychological deficits in schizophrenia (SZ), schizophrenia relatives and bipolar disorder (BD). We acquired T1-weighted anatomical MRI sequences in 209 participants: 57 SZ patients, 47 first-degree relatives of SZ patients, 48 BD I patients and 57 healthy controls. We computed group comparisons of gray matter (GM) volume in frontal and basal ganglia regions-of-interest, followed by correlation analysis between psychomotor speed, executive functioning and learning and GM volumes in candidate regions. Several frontal GM volume reductions as well as GM increases in the thalamus and the putamen were exhibited in SZ patients as compared to controls. The same finding was observed - less pronounced - when comparing SZ relatives and controls. BD patients presented GM volume increases in the basal ganglia in comparison to controls. In SZ patients, increases in bilateral thalamus GM volume and decreases in left middle and superior frontal gyrus volume were significantly associated with worse cognitive performance. In summary, our results indicate distinct imbalances across frontal-subcortical circuits in BD, SZ relatives and SZ. The functional relevance of the findings were mainly limited to the SZ patients group: in this group, abnormalities were directly associated with cognitive performance. This result is in line with the finding that the volume alterations were strongest in SZ patients and followed by BD patients and SZ relatives., (Copyright © 2016 Elsevier B.V. All rights reserved.)

- Abstract
A potential clinical and etiological overlap between schizophrenia (SZ) and bipolar disorder (BD) has long been a subject of discussion. Imaging studies imply functional and structural alterations of the hippocampus in both diseases. Thus, imaging this core memory region could provide insight into the pathophysiology of these disorders and the associated cognitive deficits. To examine possible shared alterations in the hippocampus, we conducted a multi-modal assessment, including functional and structural imaging as well as neurobehavioral measures of memory performance in BD and SZ patients compared with healthy controls. We assessed episodic memory performance, using tests of verbal and visual learning (HVLT, BVMT) in three groups of participants: BD patients (n = 21), SZ patients (n = 21) and matched (age, gender, education) healthy control subjects (n = 21). In addition, we examined hippocampal resting state functional connectivity, hippocampal volume using voxel-based morphometry (VBM) and fibre integrity of hippocampal connections using diffusion tensor imaging (DTI). We found memory deficits, changes in functional connectivity within the hippocampal network as well as volumetric reductions and altered white matter fibre integrity across patient groups in comparison with controls. However, SZ patients when directly compared with BD patients were more severely affected in several of the assessed parameters (verbal learning, left hippocampal volumes, mean diffusivity of bilateral cingulum and right uncinated fasciculus). The results of our study suggest a graded expression of verbal learning deficits accompanied by structural alterations within the hippocampus in BD patients and SZ patients, with SZ patients being more strongly affected. Our findings imply that these two disorders may share some common pathophysiological mechanisms. The results could thus help to further advance and integrate current pathophysiological models of SZ and BD.
