RESUMO

Background: Neuroimaging studies have provided valuable insights into the macroscale impacts of antidepressants on brain functions in patients with major depressive disorder. However, the findings of individual studies are inconsistent. Here, we aimed to provide a quantitative synthesis of the literature to identify convergence of the reported findings at both regional and network levels and to examine their associations with neurotransmitter systems. Methods: Through a comprehensive search in PubMed and Scopus databases, we reviewed 5,258 abstracts and identified 37 eligible functional neuroimaging studies on antidepressant effects in major depressive disorder. Activation likelihood estimation was used to investigate regional convergence of the reported foci of consistent antidepressant effects, followed by functional decoding and connectivity mapping of the convergent clusters. Additionally, utilizing group-averaged data from the Human Connectome Project, we assessed convergent resting-state functional connectivity patterns of the reported foci. Next, we compared the convergent circuit with the circuits targeted by transcranial magnetic stimulation (TMS) therapy. Last, we studied the association of regional and network-level convergence maps with the selected neurotransmitter receptors/transporters maps. Results: We found regional convergence of the reported treatment-associated increases of functional measures in the left dorsolateral prefrontal cortex, which was associated with working memory and attention behavioral domains. No regional convergence was found across foci of alterations in functional imaging associated with antidepressants. Moreover, we found network-level convergence of functional alterations in a circuit that was prominent in the frontoparietal and salience networks. This circuit was co-aligned with a circuit targeted by anti-subgenual TMS therapy. We observed no significant correlations between our meta-analytic findings with the maps of neurotransmitter receptors/transporters. Conclusion: Our findings highlight the importance of the left dorsolateral prefrontal cortex, as well as frontoparietal network and the salience network in the therapeutic effects of anti-depressants, possibly associated with their role in improving executive functions and emotional processing.

RESUMO

According to their nature, rewarding stimuli are classified as primary (e.g., food, sex) and secondary (e.g., money) rewards. Neuroimaging studies have provided valuable insights in neural reward processing and its various aspects including reward expectation, outcome and prediction error encoding. However, there is only limited evidence of whether the two different types of rewards are processed in common or distinct brain areas, in particular when considering the different functions of reward processing. We analyzed a sample of 42 healthy, male participants using task-based functional magnetic resonance imaging (fMRI) during a variant of the monetary incentive delay task. We aimed to investigate the effects of three different rewarding stimuli-two primary (food and sex) and one secondary (money)-on the various functions of reward processing. To provide a thorough description, we focused on 12 brain regions of interest and utilized the Bayes factor bound (BFB) to express stimulus-related main effects and pairwise differences at different levels of evidence, ranging from weak to decisive. Our results revealed a dominance of sexually charged stimuli in engaging the brain's reward structures for all investigated aspects of reward processing. Nevertheless, the ventral tegmental area, amygdala, ventral caudate, ventromedial prefrontal cortex, subgenual anterior cingulate cortex, and lateral orbitofrontal cortex were activated by both primary and secondary reward outcomes. For other reward processing functions, i.e., reward expectation and the prediction error, effects of the different stimuli were weaker, and effects from one reward type cannot easily be generalized to the other.

RESUMO

AIM OF THE STUDY: Evaluation of the impact of a de-escaleted chemotherapy regimen consisting of capecitabine (Cap) on invasive disease-free survival (iDFS) in patients ≥65 years with node-positive/high-risk node-negative early breast cancer (BC) receiving ibandronate (Ib). METHODS: ICE (Ib with or without Cap in Elderly patients with early breast cancer) was a multicentre phase 3 clinical trial with a 2020 update of long-term follow-up for overall survival enroling node-positive/high-risk node-negative patients ≥65 years with early BC. Patients were randomised to Cap 2000 mg/m² day 1-14 q3w for 6 cycles plus Ib (50 mg p.o. daily or alternatively 6 mg intravenous q4w) or Ib alone for 2 years. Endocrine therapy was recommended for hormone receptor (HR)-positive patients. The primary endpoint was iDFS analysed using Cox proportional hazards regression and log-rank analysis. RESULTS: 1358 (96.4%) of 1409 randomised patients started treatment. 564 (83.4%) completed 6 cycles of Cap. 513 (77.7%) and 516 (78.8%) completed Ib in the Cap+Ib and Ib alone arm, respectively. Median age was 71 (range 64-88) years, 1099 (81%) were HR-positive, 705 (51.9%) node-negative. At a median follow-up of 61.3 months, 5-year iDFS was 78.8% for Cap+Ib versus 75.0% for Ib alone (p = 0.80). Effects were independent of age, nodal, and HR status. The addition of Cap caused significantly higher skin and gastrointestinal toxicity. CONCLUSIONS: The adjuvant combination of Cap+Ib did not show significantly better iDFS than Ib alone in node-positive/high-risk node-negative older BC patients, of whom HR-positive patients were also treated with endocrine therapy. TRIAL REGISTRATION: Study in elderly patients with early breast cancer (ICE), NCT00196859, https://clinicaltrials.gov/ct2/show/NCT00196859?term=NCT00196859.

RESUMO

BACKGROUND: Levonorgestrel (LNG)-intrauterine devices (IUDs) are an effective method of contraception; however, there is growing evidence regarding potential psychiatric side effects such as depressive symptoms, anxiety, and suicidal thoughts. Therefore, we conducted this systematic review to summarise the psychiatric effects of using LNG-IUDs. METHODS: We searched six databases (MEDLINE, Web of Science, Scopus, Science Direct, Cochrane Library, and PsycInfo), and we included all study designs. The included studies were extracted, quality assessed, and qualitatively summarised. RESULTS: Out of the screened studies, only 22 were finally included. While ten studies showed increased depressive symptoms, two studies showed reduced symptoms. Moreover, one study showed increased anxiety, another one reported an increased risk of suicide, four studies concluded no association with depressive symptoms, and four other studies showed uncertainty about a potential association but mentioned other psychiatric symptoms. CONCLUSION: Despite unreliable data, many studies report psychiatric symptoms associated with LNG-IUDs, predominantly depression. Gynaecologists, general practitioners, and psychiatrists should therefore be aware of these potential risks, especially depressive symptoms and suicidality. Counselling patients about these risks should be mandatory. Further studies should investigate the absolute risk of mental disorders associated with LNG-IUDs and other hormonal contraceptives.KEY MESSAGESMany researchers are reporting adverse psychiatric events associated with levonorgestrel intrauterine devices (LNG-IUDs).Despite their effectiveness, a proper psychiatric assessment should be done before inserting LNG-IUDs.Proper counselling regarding the depressive symptoms and suicidality should be done by the treating obstetrician.Further studies should investigate the absolute risk of mental disorders associated with LNG-IUDs and other hormonal contraceptives.

RESUMO

Non-suicidal self-injury (NSSI), as a highly prevalent psychiatric symptom in adolescents and young adults, is defined as the deliberate destruction of body tissue without suicidal intent. Impulsivity and dysfunctional response inhibition have been suggested to play a central role in adolescents' vulnerability to self-harm. To investigate the potentially distinct neurobiology of NSSI, we used a well-established Go/No Go task in which activation of the inferior frontal gyrus (IFG) and dorsal anterior cingulate cortex (dACC) is interpreted as a neural correlate of processing failed response inhibition. Task-based functional magnetic resonance imaging data were obtained from 14 adolescents with a diagnosis of major depression and a history of NSSI (MD-NSSI), 13 depressed adolescents without NSSI (MD-only), and 14 healthy controls (HC). In line with hypotheses of dysfunctional response inhibition, we observed increased rates of commission errors in MD-NSSI along with significantly reduced error-related activations of the dACC and IFG. Intact response inhibition, as reflected by low commission error rates not different from HC, was observed in MD-only, along with increased activation of the error-processing network. Our findings support the hypothesis of a distinct neurobiological signature of NSSI. Further research on biomarkers of NSSI could focus on behavioral and neural correlates of failed response inhibition.

RESUMO

Psychiatric disorders are widely underreported diseases, especially in their early stages. So far, there is no fluid biomarker to confirm the diagnosis of these disorders. Proteomics data suggest the synaptic protein glutamate receptor 4 (GluR4), part of the AMPA receptor, as a potential diagnostic biomarker of major depressive disorder (MDD). A novel sandwich ELISA was established and analytically validated to detect GluR4 in cerebrospinal fluid (CSF) samples. A total of 85 subjects diagnosed with MDD (n = 36), bipolar disorder (BD, n = 12), schizophrenia (SCZ, n = 12) and neurological controls (CON, n = 25) were analysed. The data exhibited a significant correlation (r = 0.74; CI:0.62 to 0.82; p < 0.0001) with the antibody-free multiple reaction monitoring (MRM) mass spectrometry (MS) data. CSF GluR4 levels were lower in MDD (p < 0.002) and BD (p = 0.012) than in CON. Moreover, subjects with SCZ described a trend towards lower levels than CON (p = 0.13). The novel GluR4 ELISA may favour the clinical application of this protein as a potential diagnostic biomarker of psychiatric disorders and may facilitate the understanding of the pathophysiological mechanisms behind these disorders.

RESUMO

BACKGROUND: A set of enduring conditions have been reported in the literature involving persistent sexual dysfunction after discontinuation of serotonin reuptake inhibiting antidepressants, 5 alpha-reductase inhibitors and isotretinoin. OBJECTIVE: To develop diagnostic criteria for post-SSRI sexual dysfunction (PSSD), persistent genital arousal disorder (PGAD) following serotonin reuptake inhibitors, post-finasteride syndrome (PFS) and post-retinoid sexual dysfunction (PRSD). METHODS: The original draft was designed using data from two published case series (Hogan et al., 2014 and Healy et al., 2018), which represent the largest public collections of data on these enduring conditions. It was further developed with the involvement of a multidisciplinary panel of experts. RESULTS: A set of criteria were agreed upon for each of the above conditions. Features of PSSD, PFS and PRSD commonly include decreased genital and orgasmic sensation, decreased sexual desire and erectile dysfunction. Ancillary non-sexual symptoms vary depending on the specific condition but can include emotional blunting and cognitive impairment. PGAD presents with an almost mirror image of unwanted sensations of genital arousal or irritability in the absence of sexual desire. A new term, post-SSRI asexuality, is introduced to describe a dampening of sexual interest and pleasure resulting from a pre-natal or pre-teen exposure to a serotonin reuptake inhibitor. CONCLUSIONS: These criteria will help in both clinical and research settings. As with all criteria, they will likely need modification in the light of developments.

RESUMO

There has recently been a renewal of interest in psychedelic research on the use of psilocybin in psychiatric treatment and, in particular, for the treatment of major depressive disorder (MDD). Several state-of-the-art studies have provided new insight into the mechanisms of action of psilocybin and its therapeutic potential. Nevertheless, many questions remain unanswered. With this review, we provide an overview of the current state of research on the potential mechanisms of psilocybin, its antidepressant potential, and the associated risks and adverse effects, to provide an update on a controversial topic discussed in psychopharmacology. A database search was conducted in Medline including articles on psilocybin over the period of the last 20 years. Despite the promising progress in understanding the mechanisms of psilocybin, the exact antidepressive mechanism and the role of the psychedelic experience remain elusive. The studies included in this review found high treatment effect sizes for psilocybin as an antidepressant. However, the results must be regarded as preliminary due to several limitations. Although the current studies observed no severe adverse events, several questions regarding safety and utility remain and must be subject of future research.

RESUMO

Neuroinflammation has been connected to the pathophysiology of major depressive disorder (MDD) and neurochemical biomarkers of glial pathology could aid the diagnosis and might support patient stratification and monitoring in clinical trials. Our study aimed to determine the utility of glial fibrillary acidic protein (GFAP), a marker of astrocyte activation, for the differential diagnosis and monitoring of MDD. Employing Simoa technology we measured levels of GFAP in prospectively collected serum samples from 81 age-matched patients with MDD, schizophrenia (SZ), bipolar disorder (BP), and healthy controls (HC). Highest GFAP levels were determined for MDD. At a cut-off of 130 pg/ml, MDD could be discriminated with 87% sensitivity from SZ and BP (specificity 70%) and from HC (specificity 56%). GFAP levels increased with age (r = 0.5236, p = 0.0002) and with MDD severity quantified based on the Montgomery-Åsberg Depression Rating Scale (r = 0.4308, p = 0.0221). Neurofilament light chain serum levels were not different in the diagnostic groups and not associated with GFAP levels (r = 0.0911, p = 0.576) pointing to an independence of astrocyte activation on neurodegeneration. Our study provides first evidence that serum GFAP levels could improve the differential diagnosis of MDD and that depression severity could be objectively quantified using serum GFAP levels. Furthermore, serum GFAP might represent a marker to monitor astroglial pathology in the course of MDD.

RESUMO

Background: Spinal Muscular Atrophy (SMA) is a severe neurodegenerative disease, characterized by progressive muscle weakness and atrophy. The approval of the antisense oligonucleotide (ASO) nusinersen now provides an effective pharmacological approach with the potential to slow down or stop disease progression with a potentially major impact on patients' well-being. Objective: This study evaluates quality of life (QoL) in pediatric and adult patients over the course of therapy with nusinersen. Methods: Twenty-six SMA patients treated with nusinersen were evaluated regarding global QoL (gQoL), health-related QoL (HRQoL) and depressiveness. Assessments were conducted three times over the first 6 months of treatment. Applied were different questionnaires: the Anamnestic Comparative Self-Assessment (ACSA) for gQoL, the Short Form-36 Health Survey (SF-36) for HRQoL in adult patients and the ALS Depression Inventory 12 Items (ADI-12) for depressiveness. The sample was matched with 22 healthy controls. Results: Despite severe physical restrictions, patients reported high levels of QoL and low levels of depressiveness at study entry. Early disease onset and low levels of physical functioning were associated with better gQoL and lower levels of depressiveness. A significant decrease of gQoL in patients was evident over the course of the study. Still, adult patients reported a significant increase in perceived health. Conclusions: Our study provides first insight that SMA patients experience a gQoL superior to healthy controls at start of therapy. This might indicate patients' high hopes and expectations toward treatment. gQoL returns to a level similar to that of healthy controls over the course of therapy.

RESUMO

The clinical presentation of major depression (MD) is heterogenous and comprises various affective and cognitive symptoms including an increased sensitivity to errors. Various electrophysiological but only few functional magnetic resonance imaging (fMRI) studies investigated neural error processing in MD with inconsistent findings. Thus, reliable evidence regarding neural signatures of error processing in patients with current MD is limited despite its potential relevance as viable neurobiological marker of psychopathology. We therefore investigated a sample of 16 young adult female patients with current MD and 17 healthy controls (HC). During fMRI, we used an established Erikson-flanker Go/NoGo-paradigm and focused on neural alterations during errors of commission. In the absence of significant differences in rates of errors of commission in MD compared to HC, we observed significantly (p < 0.05, FWE-corrected on cluster level) enhanced neural activations of the dorsal anterior cingulate cortex (dACC) and the pre-supplementary motor area (pre-SMA) in MD relative to HC and thus, in brain regions consistently associated to neural error processing and corresponding behavioral adjustments. Considering comparable task performance, in particular similar commission error rates in MD and HC, our results support the evidence regarding an enhanced responsivity of neural error detection mechanisms in MD as a potential neural signature of increased negative feedback sensitivity as one of the core psychopathological features of this disorder.

RESUMO

An altered processing of negative salient stimuli has been suggested to play a central role in the pathophysiology of major depression (MD). Besides negative affective and social stimuli, physical pain as a subtype of negative sensory stimulation has been investigated in this context. However, the few neuroimaging studies on unpleasant sensory stimulation or pain processing in MD report heterogeneous findings. Here, we investigated 47 young females, 22 with MD and 25 healthy controls (HC) using fMRI (3.0 T). Four levels of increasingly unpleasant electrical stimulation were applied. Ratings of stimulus intensity were assessed by a visual analogue scale. fMRI-data were analyzed using a 2 × 4 ANOVA. Behavioral results revealed no group differences regarding accuracy of unpleasant stimulation level ratings and sensitivity to stimulation. Regarding neural activation related to increasing levels of unpleasant stimulation, we observed increasing activation of brain regions related to the pain and salient stimulus processing corresponding to increasingly unpleasant stimulation in controls. This modulation was significantly smaller in MD compared to controls, particularly in the dorsal anterior cingulate cortex, the somatosensory cortex, and the posterior insula. Overall, brain regions associated with the processing of unpleasant sensory stimulation, but also associated with the salience network, were highly reactive but less modulated in female patients with MD. These results support and extent findings on altered processing of salience and of negative sensory stimuli even of a non-painful quality in female patients with MD.

RESUMO

Various studies suggested alterations in pain perception in psychiatric disorders, such as borderline personality disorder (BPD) and major depression (MD). We previously investigated affective components of pain perception in BPD compared to healthy controls (HC) by increasing aversive stimulus intensities using repetitive peripheral magnetic stimulation (rPMS) and observed alterations in emotional rather than somatosensory components in BPD. However, conclusions on disorder specific alterations in these components of pain perception are often limited due to comorbid depression and medication in BPD. Here, we compared 10 patients with BPD and comorbid MD, 12 patients with MD without BPD, and 12 HC. We applied unpleasant somatosensory stimuli with increasing intensities by rPMS and assessed pain threshold (PT), cutaneous sensation, emotional valence, and arousal by a Self-Assessments Manikins scale. PTs in BPD were significantly higher compared to HC. The somatosensory discrimination of stimulus intensities did not differ between groups. Though elevated rPMS intensities led to increased subjective aversion and arousal in MD and HC, these emotional responses among intensity levels remained unchanged in BPD. Our data give further evidence for disorder-specific alterations in emotional components of pain perception in BPD with an absent emotional modulation among varying aversive intensity levels.

RESUMO

The levonorgestrel-releasing intrauterine system (LNG-IUS) is used as hormonal contraception by millions of women worldwide. It is considered as a safe device with low rates of systemic adverse drug reactions (ADRs). However, an emerging evidence suggest mood changes as ADRs. Whereas most of these studies report psychiatric ADRs after the first implantation of the LNG-IUS, it has to be considered that these may also occur after replacement, even when psychiatric symptoms were not evident at the time of the initial insertion. A potential explanation for the development of psychiatric ADRs in subsequent LNG-IUS may rely on fluctuations of sex hormones throughout the female life cycle with changing windows of vulnerabilities for developing mood disorders. Thus, the reliable contraception for women remains a continual challenge. We present the case of a 41-year-old woman that used the LNG-IUS (Mirena®) for contraception over 5 years without any complaints. Within the first weeks after insertion of the second LNG-IUS, she developed a depressive syndrome and anxieties. An extensive somatic, including gynecological examination revealed no pathological findings and a mental disorder was suggested. Due to the patient´s request and the recommendation of her psychiatrist, the device was removed and led to a remission of her mental complaints up to a 6- and 12-months follow-up. Beyond the mood changes considerably affecting her quality of life, the patient raised the concerns that she has never been informed about potential ADRs on mental health and her remarks regarding the potential association between psychiatric symptoms and the LNG-IUS were considered as groundless. With this case, we strengthen previous observations regarding mood changes under LNG-IUS. Moreover, we illustrate that psychiatric symptoms may also occur as ADRs during the subsequent insertion. Thus, we emphasize that psychiatric symptoms have to be clearly communicated as ADRs to patients with LNG-IUS within a written informed consent and should be routinely examined by gynecologists.

RESUMO

Borderline personality disorder (BPD) is characterized by interpersonal disturbances and dysfunctional behavior such as non-suicidal self-injury (NSSI). We recently observed neural alterations in BPD during social inclusion by enhanced activations within the dorsomedial prefrontal cortex (dmPFC) and the posterior cingulate cortex (PCC). To examine the specificity of these neural alterations, we now investigated participants with NSSI but without BPD and compared them to BPD and healthy controls (HC). Considering the association between NSSI and BPD, we further examined neural commonalities during social inclusion. Fifteen females diagnosed with BPD, 16 with NSSI and 17 HC were investigated by fMRI and the cyberball paradigm, focusing on social inclusion (p < 0.05; FWE on cluster-level). To examine neural commonalities between BPD and NSSI compared to HC, we computed a conjunction analysis on neural activations under social inclusion. Significant increases in neural activation were observed in BPD within the dmPFC under social inclusion compared to NSSI and HC, whereas neural activations within the PCC did not differ between BPD and NSSI. The conjunction analysis revealed a common neurofunctional increase within the pregenual anterior cingulate cortex and the anterior insula in both, BPD and NSSI. We provide a further evidence regarding a disorder-specific neural reactivity within the dmPFC during social inclusion in BPD, whereas PCC activations may represent an unspecific neural alteration in BPD when compared to NSSI. In contrast, both clinical groups revealed a common neural increase within the salience network that may support the assumptions of a developmental continuum between these two psychiatric conditions.

RESUMO

One of the most common adverse events (AEs) occurring during treatment with aromatase inhibitors (AIs) is musculoskeletal pain. The aim of our study was to analyze the influence of preexisting muscle/limb pain and joint pain on the development of AI-induced musculoskeletal AEs. Women eligible for upfront adjuvant endocrine therapy with letrozole were included in the PreFace study, a multicenter phase IV trial. During the first treatment year, they were asked to record musculoskeletal AEs monthly by answering questions regarding pain symptoms and rating the pain intensity on a numeric rating scale from 0 (no pain) to 10 (very strong pain). Pain values were compared using nonparametric statistical tests. Overall, 1,416 patients were evaluable. The average pain value over all time points in women with preexisting muscle/limb pain was 4.3 (median 4.3); in those without preexisting pain, it was 2.0 (median 1.7). In patients without preexisting muscle/limb pain, pain levels increased relatively strongly within the first 6 months (mean increase +0.9, p < 0.00001) in comparison with those with preexisting pain (mean increase +0.3, p < 0.001), resulting in a statistically significant difference (p < 0.00001) between the two groups. The development of joint pain was similar in the two groups. Women without preexisting muscle/limb pain or joint pain have the greatest increase in pain after the start of adjuvant AI therapy. Women with preexisting pain have significantly higher pain values. The main increase in pain values takes place during the first 6 months of treatment.

RESUMO

Human sexual behavior is mediated by a complex interplay of cerebral and spinal centers, as well as hormonal, peripheral, and autonomic functions. Neuroimaging studies identified central neural signatures of human sexual responses comprising neural emotional, motivational, autonomic, and cognitive components. However, empirical evidence regarding the neuromodulation of these neural signatures of human sexual responses was scarce for decades. Pharmacological functional magnetic resonance imaging (fMRI) provides a valuable tool to examine the interaction between neuromodulator systems and functional network anatomy relevant for human sexual behavior. In addition, this approach enables the examination of potential neural mechanisms regarding treatment-related sexual dysfunction under psychopharmacological agents. In this article, we introduce common neurobiological concepts regarding cerebral sexual responses based on neuroimaging findings and we discuss challenges and findings regarding investigating the neuromodulation of neural sexual stimulus processing. In particular, we summarize findings from our research program investigating how neural correlates of sexual stimulus processing are modulated by serotonergic, dopaminergic, and noradrenergic antidepressant medication in healthy males.

RESUMO

PURPOSE: Evidence shows that genetic and non-genetic risk factors for breast cancer (BC) differ relative to the molecular subtype. This analysis aimed to investigate associations between epidemiological risk factors and immunohistochemical subtypes in a cohort of postmenopausal, hormone receptor-positive BC patients. METHODS: The prospective, single-arm, multicenter phase IV PreFace study (Evaluation of Predictive Factors Regarding the Effectivity of Aromatase Inhibitor Therapy) included 3529 postmenopausal patients with hormone receptor-positive early BC. Data on their epidemiological risk factors were obtained from patients' diaries and their medical histories. Data on estrogen receptor, progesterone receptor, and HER2 receptor status were obtained from pathology reports. Patients with incomplete information were excluded. Data were analyzed using conditional inference regression analysis, analysis of variance, and the chi-squared test. RESULTS: In a cohort of 3392 patients, the strongest association with the molecular subtypes of BC was found for hormone replacement therapy (HRT) before diagnosis of early BC. The analysis showed that patients who took HRT at diagnosis had luminal A-like BC more often (83.7%) than those who had never taken HRT or had stopped taking it (75.5%). Luminal B-like BC and HER2-positive BC were diagnosed more often in women who had never taken HRT or had stopped taking it (13.3% and 11.2%, respectively) than in women who were taking HRT at diagnosis of BC (8.3% and 8.0%, respectively). CONCLUSIONS: This analysis shows an association between HRT and the distribution of molecular subtypes of BC. However, no associations between other factors (e.g., age at diagnosis, body mass index, smoking status, age at menopause, number of deliveries, age at first delivery, breastfeeding history, or family history) were noted.

RESUMO

Humans engage in social interactions and have a fundamental need and motivation to establish and maintain social connections. Neuroimaging studies particularly focused on the neural substrates of social exclusion in healthy subjects (HC), borderline personality disorder (BPD), and major depression (MD). However, there is evidence regarding neural alterations also during social inclusion in BPD that we intended to elucidate in our study. Considering that patients with BPD often have comorbid MD, we investigated patients with BPD, and comorbid MD, patients with MD without BPD, and a sample of HC. By investigating these two clinical samples within one study design, we attempted to disentangle potential confounds arising by psychiatric disorder or medication and to relate neural alterations under social inclusion specifically to BPD. We investigated 48 females (15 BPD and MD, 16 MD, and 17 HC) aged between 18 and 40 years by fMRI (3T), using the established cyberball paradigm with social exclusion, inclusion, and passive watching conditions. Significant group-by-condition interaction effects (p < 0.05, FWE-corrected on cluster level) were observed within the dorsolateral (dlPFC) and dorsomedial prefrontal cortex (dmPFC), the temporo-parietal junction (TPJ), the posterior cingulate cortex (PCC), and the precuneus. Comparisons of estimated neural activations revealed that significant interaction effects were related to a relative increase in neural activations during social inclusion in BPD. In detail, we observed a significant increase in differential (social inclusion vs. passive watching) neural activation within the dmPFC and the PCC in BPD compared to both, MD and HC. However, significant interaction effects within the dlPFC and the TPJ could not specifically be linked to BPD considering that they did not differ significantly between the two clinical groups in post-hoc comparisons. Our study supports previous results on effects of social and inclusion in BPD, and provides further evidence regarding disorder specific neural alterations in BPD for brain regions associated with self-referential and mentalizing processes during social inclusion.
