Technology Addiction and Social Connectedness in Psychiatric Illness: A Multicenter Study.

Technology addiction is an increasingly important public health problem all over the world that negatively affects people's mental and physical health. In this study, we examined technology addiction and social connectedness levels of psychiatric patients who admitted to clinics in different geographical regions of Turkey. A total of 642 people with a diagnosis of psychiatric illness who applied to psychiatry clinics in İstanbul, Elaziğ, Malatya, Yozgat, Adıyaman, and Bingöl provinces were included. Sociodemographic data form, Technology Addiction Scale (TAS), and Social Connectedness Scale (SCS) were applied to all participants. The total score of the TAS in patients diagnosed with anxiety disorder and somatoform disorder was significantly higher than the other patient groups (p<0.001). Patients diagnosed with anxiety disorder showed a significant difference from other patient groups in terms of SCS score (p<0.001). Anxiety disorder was found to be the highest in TAS total score and sub-dimensions and the lowest in SCS score, while major depressive disorder was found to be the lowest in TAS total score and sub-dimensions and the highest in SCS score. The multiple linear regression analysis showed that the total score of the TAS was predicted by the SCS score (β=-1.857, p<0.001) and the SCS score was predicted by age (β=0.046, p=0.049) and the total score of the TAS (β=-0.316, p<0.001). As a result of this study, we can say that psychiatric patients have a moderate level of technology addiction, these people have high levels of social connectedness, and psychiatric patients with technology addiction have a high level of social belonging.

Eye Movement Desensitization and Reprocessing of Maleficium: Case Study of a “Cursed” Woman Suffering From Unexplained Pain

The present case study describes the application of the eye movement desensitization and reprocessing (EMDR) approach to a patient experiencing the distressing memory of an act of apparent ‘maleficium.’ The patient was in treatment due to somatic symptom disorder. Transcripts from the EMDR desensitization session were used to qualitatively describe both the dysfunctional stored memories associated with the apparent sorcery and the healing associations contributing to the zeroing of the alleged subjective unit of disturbance. Changes in psychometric measures of symptoms showed that the patient experienced a relevant and unexpected reduction of different clinical outcomes, with a specific notable effect on the subjective evaluation of pain. An explanation based on adaptive information processing is offered to explain this last unexpected finding.

Comorbidity rates of autism spectrum disorder and functional neurological disorders: A systematic review, meta-analysis of proportions and qualitative synthesis.

Autism spectrum disorder (ASD) and functional neurological disorders (FND) are relatively common conditions, and there has been recent interest in the overlap between them. Both conditions share core features of alexithymia, impaired interoception and deficits in attentional focus. To date, relatively little is known about the comorbidity rates between ASD and FND. This is the first meta-analysis and qualitative synthesis on the subject. We found that around 10% of children presenting with functional seizures have a comorbid ASD diagnosis. People with ASD are more likely than the neurotypical population to have functional somatic disorders, and there is also evidence that ASD rates are higher for other FNDs such as functional motor disorders. Since FND comes with risks of unnecessary medical procedures and investigations, it is important to recognize the potential for people with ASD to have an FND comorbidity.

Cigarette Smoking in Women Victims of Police-Reported Intimate Partner Violence: The Role of Childhood Maltreatment, Type of Partner Abuse, and Psychological Distress Symptoms

ABSTRACT Existing research on the relationship between intimate partner violence (IPV) and cigarette smoking primarily involves low-risk, physical IVP-focused studies on community women. As a result, the risks associated with cigarette smoking in women victims of severe IPV have not been fully explored. This study examined the association between exposure to different forms of childhood maltreatment, exposure to physical, psychological, and sexual IPV, and current psychological distress symptoms with cigarette smoking in a high-risk sample of women victims of police-reported severe IPV. Participants included 162 women victims of police-reported severe IPV recruited in shelters for domestic violence and Child Protective Services in Portugal. Participants provided self-reports on childhood maltreatment physical, psychological, and sexual violence), physical, psychological, and sexual IPV, psychological distress symptoms (anxiety, depressive, somatic, and posttraumatic stress disorder symptoms), and daily cigarette consumption. Results revealed significant associations between daily cigarette consumption and exposure to IPV, physical abuse during childhood, psychological IPV, and anxiety symptoms in women experiencing police-reported severe IPV. Childhood maltreatment may increase vulnerability for emotion dysregulation, promoting addictive behaviors to regulate distress. Smoking can be an unhealthy regulating strategy to reduce the distress related to chronic exposure to psychological IPV. Future effective health promotion interventions in women facing severe forms of IPV may target emotional regulation and incorporate a trauma-focused approach.

Mentally ill people with means-tested benefits at the job center : Diagnosis spectrum and care-First results from the LIPSY project

Although people receiving means-tested benefits are regularly taken care of at the job center, little is known about their mental health situation and mental health care. The aim of the study was to describe the diagnostic spectrum and the functional status as well as the mental health care utilization of individuals with mental illnesses who are receiving means-tested benefits. Mentally ill people with means-tested benefits were recruited at the job center as part of the "Leipzig Individual Placement and Support for Mentally Ill People" (LIPSY) project, where they were initially diagnosed according to ICD-10 and included in the project if they had amental disorder. Mental healthcare utilization was recorded. In the present study, data from n = 583 consecutively included persons were analyzed descriptively and by multivariate statistics. Of the study participants 60.7% (n = 583; 51.5% female; average age36years; unemployed for an average of 4.8years) suffered from affective disorders, followed by neurotic, stress and somatoform disorders (42.5%). With amean global assessment of functioning (GAF) value of 49.4 (SD 7.7), there was on average aserious impairment. Nearly half of the subjects (48.5%) had never received psychotherapeutic, psychiatric or neurological treatment in the 6 months prior to inclusion in the project. It could be shown that there is abroad spectrum of mental disorders with substantial functional impairment. The data suggest that this group is significantly undertreated and difficult to reach.

Влияние различных факторов риска на формирование вторичных органических психических расстройств у лиц пожилого возраста с алкогольной зависимостью, сформированной в среднем и пожилом возрасте

Background. Alcohol slows down the work of the brain and central nervous system, leads to deterioration of memory and concentration, cognitive disorders, and the formation of organic mental disorders. Due to the retirement of elderly people, some of them resort to taking alcohol as an adaptogen to alleviate various social, mental and psychological disorders, which can lead to the emergence of new or exacerbation of existing somatic disorders, the formation of alcoholism, as well as organic mental disorders. Aim. To investigate the risk factors (RF) for the formation of secondary organic mental disorders (SOMD) in elderly people with alcohol dependence (AD), formed in middle and old age. Patients and methods. The study included only male patients for the purity of the study aged 60 to 74 years (average age 67.5±7.2), who were divided into 2 groups depending on the age of occurrence of AD: group 1 – 21 people (36.2%), AD occurred at the age of 51.6±1.2 years, and the symptoms of SOMD at 61.8±2.1 years; group 2 – 37 people (63.8%), AD occurred at the age of 64.5±2.5 years, and SOMD at 71.3±2.8 years. The following methods were used: questionnaire – using the developed "Anamnestic chart", clinical (anamnesis collection), statistical (parametric and nonparametric). Results. The main factors of the formation of SOMD in people with formed AD in middle and old age are combinations of various RF, as well as a monofactor in the form of chronic alcohol abuse, the proportion of which varies depending on the age of AD formation. Conclusion. When AD is formed in old age, combinations of RF have a greater influence on the development of SOMD. And in the formation of AD in middle age, both alcohol, as an exogenous mono-damaging factor, and a combination of RF contribute to the formation of SOMD. Hereditary burden of alcoholism affects the progrediency of alcoholism, but does not play a role in the rate of formation of SOMD. The formation of alcoholism in middle age is combined with a relatively slow rate of formation of SOMD and a smaller number of associated somatic pathology, and when formed in old age – with a relatively fast rate of development of SOMD and a large number of associated somatic pathology.

Применение Мебикса в психиатрии и общей медицине: актуальность, перспективы, клинические примеры

Anxiety disorders, except the manifestations of anxiety itself, are characterized by a broad spectrum of cognitive and somatic symptoms significantly reducing the individual’s quality of life and increasing the risk of somatic disorders. The rate of cardiovascular, respiratory, gastrointestinal, and other disorders throughout life is significantly higher in people suffering from anxiety. Furthermore, many symptoms of anxiety and panic/fear mimic manifestations of somatic disorders. Optimal treatment of anxiety disorders includes both pharmacological and psychotherapeutic interventions. At the same time, psychotherapy is not always available for patients, and internists not always decide to prescribe psychotropic medication, for example antidepressants. In such situations, nonbenzodiazepine anxiolytics showing high efficacy and tolerability can be used. Mebix, having an adaptogenic effect on the central nervous system and a stabilizing effect on the autonomic nervous system, that affects almost all neurotransmitters can be considered one of such drugs. The paper reports clinical cases of patients with anxiety disorders, who were treated with Mebix as monotherapy or in combination with antidepressants.

Neuropsychological features of somatic symptom disorder and depression/anxiety in Taiwan: An analysis based on the comorbidity status

Individuals with somatic symptom disorder (SSD) often have comorbid depression or anxiety, but whether SSD is associated with specific neuropsychological functions has yet to be fully examined. We analyzed which neuropsychological features are more closely associated with SSD, anxiety, and depression. In this case-control study, we recruited 140 individuals with SSD, 104 individuals with affective disorders without SSD, and 159 healthy controls in Taiwan. We collected DSM-5 diagnoses, questionnaire scores, and performance on eight tasks from the Cambridge Neuropsychological Test Automated Battery (CANTAB) for each participant. Several CANTAB tasks involving attention, executive function, and social cognition showed significant group differences. In the adjusted analysis, the tasks significantly associated with SSD were the Match to Sample Visual Search (MTS) and the Emotion Recognition Task (ERT). Among the questionnaires, the Cognitions about Body and Health Questionnaire showed the most significant associations with the tasks, specifically with Rapid Visual Information Processing, MTS, Paired Associates Learning, Spatial Working Memory, Intra-Extra Dimensional Set Shift, and ERT. We conclude that the MTS and ERT tasks show significant relationships with both SSD diagnosis and related questionnaires. These tasks primarily involve selective attention and negative emotion regulation.

Abnormalities in the absolute power of Delta and Alpha rhythms in the frontal lobe of patients suffering from psychosomatic disorders.

Psychosomatic disorders (somatic symptom disorder - SSD) constitute a heterogeneous group of medical conditions characterized by somatic symptoms without explained somatic causes. Due to the complexity of symptoms, they present a significant medical, social and economic challenge, and diagnosing and treating these disorders remains a substantial clinical challenge. The aim of the conducted research was an attempt to identify characteristic patterns in the surface-level brain bioelectrical activity of individuals experiencing psychosomatic disorders. The obtained results may contribute to understanding the pathomechanism of these disorders and developing objective methods for diagnosis and differentiation of functional dysfunctions. The study involved a group of 49 individuals: 30 patients with somatic symptom disorder (SSD) and 19 individuals in the control group. Resting-state EEG signals were recorded from the subjects under two experimental conditions (eyes open, eyes closed). The recorded signals underwent quantitative EEG (QEEG) analysis followed by statistical analysis. EEG signal analysis revealed statistical differences between the studied groups in terms of absolute power in the Alpha band (8-12 Hz) in frontal areas (electrodes F3, Fz, F4) under eyes-open conditions, as well as in the Delta band (1-4 Hz) in the right frontal area (electrode F4) under eyes-closed conditions. Similar changes were not observed in the Beta (12-25 Hz) or High Beta (25-30 Hz) bands. The detected abnormalities in the surface-level brain bioelectrical activity may indicate potential disturbances in the reception and interpretation of visceral sensations in patients with psychosomatic disorders. The lack of differences in higher frequencies could be helpful in the differential diagnosis between these disorders and other anxiety disorders where psychosomatic symptoms are observed. The obtained results could also be useful in planning protocols involving various neurotherapeutic methods.

Efficacy of sequential primary motor and prefrontal cortices intermittent Theta burst stimulation in persistent somatoform PAIN disorder (TAP-PAIN): A randomized sham-controlled pilot trial

Aim: There is a need to elucidate intermittent Theta burst stimulation (iTBS) as a novel treatment in persistent somatoform pain disorder (PSPD). Methods: Twenty patients were randomly allocated to active iTBS (n = 11) and sham iTBS (n = 9) and received 10 iTBS sessions, 2 sessions per day, sequentially to primary motor and dorsolateral prefrontal cortices for 5 days in a week. Each iTBS session comprised of 2 sec. per train of 10 bursts (3 pulses per burst at 50 Hz; total 30 pulses) and were given with a gap of 5 Hz, total of 20 trains, and 600 pulses. Visual Analogue Scale, Brief Pain Inventory and Global Pain Scale (GPS), Montgomery and Asberg Depression Rating Scale, Hamilton Anxiety Rating Scale - Anxiety, World Health Organization Quality-of-Life Scale-brief, and Pittsburgh Sleep Quality Index were applied at baseline, after last session, and at 2 weeks after last TBS session. Intention to treat analysis was conducted. Results: Both groups were comparable for baseline psychopathology scores including clinical variables like age (t = 0.865; P = 0.398), duration of illness (t = 1.600; P = 0.127), and motor threshold (t = 0.304; P = 0.765). On repeated measures ANOVA, a significant within-group time effect for VAS, BPI-Severity, BPI-Interference, BDI – II, MADRS, HAM-A, and WHOQOL- BREF was found for active and sham TBS groups, respectively. GPS scores had significant within-group (active) * time interaction (F = 11.651; P = .001; ηp2 = 0.538) and between-group * time interaction (F = 3.407; P = 0.044; ηp2 = 0.159). However, between-group * time effect interaction was lost after covariance (F = 1.726; P = 0.196; ηp2 = 0.110). Conclusion: No major adverse effects were reported. Our pilot trial concludes that safe therapeutic efficacy of iTBS in PSPD is inconclusive. Lower total number of sessions along with small sample size may limit the study findings.

Somatic Symptoms and Its Association With Anxiety and Interoception

In Somatic Symptom Disorder, individuals may misinterpret their symptoms as signs of disease. Meanwhile, interoception refers to an individual’s perception to sense internal body sensations. Interoception may play a role in the regulation of state and trait anxiety. Anxiety, in turn, is associated with somatic symptoms. A comprehensive study regarding somatic symptoms is still required to fill the knowledge gap regarding its relationships with other variables. In this study, 101 university students from Nagoya, Japan, fulfilled four questionnaires related to the study variables. The participants also completed the heartbeat counting task (HCT) to assess interoceptive accuracy and heart rate variability (HRV) measurement. The results showed that health concerns and trait anxiety are associated with somatic symptoms. In addition, the sub-scales Attention Regulation and Self-Regulation determined trait anxiety in an inverse correlation. These results suggest that interoception, particularly interoceptive sensibility, is negatively associated with trait anxiety regarding somatic symptoms. The inverse relationship could be expected, as interoceptive sensibility is a set of positive beliefs about aspects of the individual’s abilities and the tendency to consciously sense signals originating from inside their body.

Direct effects of heroin and methadone on T cell function

Opioid addiction presents a relevant health challenge, with chronic heroin use linked to detrimental effects on various aspects of physical, mental, and sociological health. Opioid maintenance therapy (OMT), particularly using methadone, is the primary treatment option for heroin addiction. Previous studies using blood samples from current heroin addicts and OMT patients have shown immunomodulatory effects of heroin and methadone on T cell function. However, various additional factors beyond heroin and methadone affect these results, including the consumption of other substances, a stressful lifestyle, comorbid psychological and somatic disorders, as well as additional medications. Therefore, we here investigated the direct effects of heroin and methadone on purified human T cells in vitro. Our results reveal that both, heroin and methadone directly suppress Tcell activation and proliferation. Strikingly, this inhibitory effect was markedly stronger in the presence of methadone, correlating with a decrease in secretion of pro-inflammatory cytokines. While heroin did not interfere with the in vitro differentiation and expansion of regulatory Tcells (Tregs), methadone significantly impaired the proliferation of Tregs. Overall, our findings suggest a direct inhibitory impact of both opioids on effector T cell function in vitro, with methadone additionally interfering with Treg induction and expansion in contrast to heroin.

The Role of Psychological Factors in Noncardiac Chest Pain of Esophageal Origin.

Noncardiac chest pain (NCCP) of esophageal origin is a challenging clinical problem of diverse etiology that affects more than 80 million Americans yearly. We assess the prevalence and impact of psychological disorders on NCCP of esophageal origin, describe possible mechanisms associated with this condition, and review psychological therapy options. Online search using PubMed and Medline from January 1, 1966, to April 30, 2023. Psychological disorders have been reported in up to 79% of patients with NCCP of esophageal origin. Several psychological disturbances have been identified with this condition, including depression, anxiety, panic disorder, phobias, and obsessive-compulsive and somatoform disorders. It is unclear whether the psychological disorders trigger the chest pain or vice versa. Multiple psychological mechanisms have been linked to chest pain and may contribute to its pathogenesis and severity. These mechanisms include cardiophobia, poor coping strategies, negative social problem solving, stress and perceived control, hypervigilance to cardiopulmonary sensations, altered pain perception, and alexithymia. Psychological therapies for NCCP of esophageal origin include cognitive behavioral therapy, hypnotherapy, physical and relaxation training, breathing retraining, and alternative medicine. Among the therapeutic options, cognitive behavioral therapy has been shown to be an effective treatment for NCCP of esophageal origin. This review raises awareness about the high prevalence of psychological disorders in NCCP of esophageal origin and highlights the need for clinical trials and trained therapists to address the management of this taxing clinical problem.

"When one has no REAL illness"-analysis of the knowledge component of mental health literacy in children and adolescents of parents with a mental illness.

Mental Health Literacy (MHL) is important in promoting youth mental health. One key aspect of MHL is knowledge about mental disorders, which is particularly relevant for populations at risk for developing mental disorders, such as children of parents with a mental illness (COPMI), representing a mechanism within the transgenerational transmission. Currently, COPMI's level of disorder knowledge in general, and about the specific parental disorder has not been comprehensively researched. We, therefore, aimed to assess COPMI's disorder knowledge and clarify its association with COPMI's age and sex exploratively. To assess both general and disorder-specific knowledge, we took a novel approach that makes disorder knowledge comparable across samples and over time. A mixed method analysis of N = 181 semi-structured MHL interviews with COPMI (aged 5 to 17 years) was carried out in the COMPARE-family study in Germany. We conducted a DSM-oriented deductive qualitative content analysis to assess COPMI's general and specific disorder knowledge. Chi-square tests served to identify age and sex differences. Children revealed limited knowledge of mental disorders in general, whereas adolescents displayed more knowledge that was also partly consistent with descriptions of classification systems like the DSM-5. The level of specific knowledge about the parent's disorder depended on the disorder group. More children displayed adequate knowledge of somatic and anxiety disorders compared to trauma and depressive disorders, and more adolescents displayed adequate knowledge of depressive and anxiety disorders. COPMI's age and sex were found to be significantly associated with disorder knowledge: adolescents exhibited higher levels of adequate general and specific disorder knowledge, and males exhibited higher levels of adequate general disorder knowledge. Assessing COPMI's disorder knowledge and identifying associated age and sex differences yield valuable insights into the knowledge component of the MHL theory. Our findings can help to improve psychoeducational interventions for COPMI by orienting them to their prevailing levels of disorder knowledge. We recommend employing and extending the DSM-oriented deductive approach to assess knowledge within MHL. Analyses involving additional assessments within the COMPARE-family study are in preparation to identify potential knowledge gains over time, and associations to COPMI's own well-being and mental health symptoms.

Convolutional Neural Network-Based Digital Diagnostic Tool for the Identification of Psychosomatic Illnesses

This paper appraises convolutional neural network (CNN) models’ capabilities in emotion detection from facial expressions, seeking to aid the diagnosis of psychosomatic illnesses, typically made in clinical setups. Using the FER-2013 dataset, two CNN models were designed to detect six emotions with 64% accuracy—although not evenly distributed; they demonstrated higher effectiveness in identifying “happy” and “surprise.” The assessment was performed through several performance metrics—accuracy, precision, recall, and F1-scores—besides further validation with an additional simulated clinical environment for practicality checks. Despite showing promising levels for future use, this investigation highlights the need for extensive validation studies in clinical settings. This research underscores AI’s potential value as an adjunct to traditional diagnostic approaches while focusing on wider scope (broader datasets) plus focus (multimodal integration) areas to be considered among recommendations in forthcoming studies. This study underscores the importance of CNN models in developing psychosomatic diagnostics and promoting future development based on ethics and patient care.

Stress and depression-aneurobiological perspective

Depression is acommon and often very debilitating disease causing ahigh number of years lost to disability worldwide. Mortality rates are high due to suicide and depression-associated somatic disorders, which seem to have abidirectional connection. Depression is considered to be stress associated. Adverse life events such as losses, interpersonal conflicts, financial issues, unemployment, and loneliness are often found in the patient history. Also childhood maltreatment is aknown risk factor. Chronic stress can cause maladaptive changes in different neurobiological systems and may contribute to the development of depression. Relevant changes have been described in the stress-response and immune systems of persons with depression and those with childhood trauma or abuse. Psychotherapy and antidepressants are both effective, and current treatment guidelines recommend their combination in severe depressive episodes.

Psychometric Properties of the Russian Version of the Somatic Symptom Disorder — B Criteria Scale

Background: in foreign science and practice, the Somatic Symptom Disorder — B Criteria Scale (SSD-12) is actively used in the diagnosis of cognitive, affective, and behavioral aspects of somatization, as well as in screening and monitoring of somatoform disorder in the general population and in patients seeking primary health care. The aim of study: adaptation of the Russian version of the SSD-12 in the general population. Participants and methods: the sample consisted of 1,535 respondents who filled out, in addition to the SSD-12, a set of diagnostic measures assessing anxiety (Generalized Anxiety Disorder-7, GAD-7), depression (Patient Health Questionnaire-9, PHQ-9), and somatization (Somatic Symptom Scale-8, SSS-8). Results: the adapted scale has a three-factor structure that allows diagnosing cognitive, affective, and behavioral aspects of somatization (SB χ2 (51) = 656, p &lt; 0,001; CFI = 0,942; TLI = 0,925; SRMR = 0,037; RMSEA = 0,088 (CI 95% 0,082–0,094)). The reliability has been proven using acceptable internal consistency. The validity was confirmed by the expected correlations between somatization according to the SSD-12 and SSS-8, anxiety according to the GAD-7, and depression according to the PHQ-9. The specificity and sensitivity were determined using ROC curves for cognitive, affective, and behavioral aspects of somatization. Conclusion: the Russian version of the SSD-12 is psychometrically consistent and can be recommended as a diagnostic instrument for assessing of cognitive, affective, and behavioral aspects of somatization in the general population.

Childhood maltreatment and transdiagnostic connectivity of the default-mode network: The importance of duration of exposure

Childhood maltreatment (CM) has been demonstrated to be associated with changes in resting-state functional connectivity of the default-mode network (DMN) across various mental disorders. Growing evidence regarding severity of CM is available but transdiagnostic research considering the role of both severity and duration of CM for DMN connectivity at rest is still scarce. We recruited a sample of participants with varying levels of CM suffering from three disorders in which a history of CM is frequently found, namely, post-traumatic stress disorder, major depressive disorder, or somatic symptom disorder, as well as healthy volunteers to examine DMN connectivity in a transdiagnostic sample. We expected to find changes in inter-network connectivity of the DMN related to higher self-reported levels of CM severity and duration. Resting-state functional magnetic resonance imaging scans of 128 participants were analyzed focusing on regions of interest (ROI-to-ROI approach) and whole-brain Seed-to-Voxel analyses with retrospectively assessed CM as predictor in a regression model. Changes in connectivity between nodes of the DMN and the visual network were identified to be associated with CM duration but not severity. CM duration showed associations with increased connectivity of the precuneus and visual regions, as well as sensory-motor regions. The observed changes in connectivity could be interpreted as an impairment of information transfer between the transmodal DMN and unimodal visual and sensory-motor regions with impairment increasing with duration of exposure to CM.

The effect of high-definition transcranial direct current stimulation on pain in somatic symptom disorder with predominant pain: A randomized single-blind sham-controlled crossover study

Somatic symptom disorder with predominant pain (SSD-P) is a commonly encountered disorder, yet treatment options often yield unsatisfactory outcomes. Transcranial direct current stimulation (tDCS) has proven useful in chronic pain conditions and may hold potential for treating somatoform pain. High-definition tDCS (HD-tDCS) offers more precise cortical stimulation than conventional tDCS. However, this modality has not been extensively studied in SSD-P. Consequently, this study aims to assess the effects of a novel HD-tDCS protocol on pain and other associated variables in patients with SSD-P. The Institute Ethics Committee approved the study, which was also registered in the Clinical Trials Registry of India. A single-blind, sham-controlled, crossover study design was employed. Thirty right-handed patients with DSM-5 diagnosis of SSD-P, aged 18 &amp;ndash; 60 years and receiving stable treatment, were enrolled through consecutive sampling. After simple randomization, two repeated, short-interval sessions (2 mA, 20 min each) of either active or sham HD-tDCS were administered, followed by a washout period of 7 days and a subsequent crossover. Assessments were conducted at baseline, week 1, and week 2. Participants in active and sham arms were comparable on all baseline parameters. At the end of the 1st week, patients in the active group showed significant improvement in the study variables compared to the sham group. By week 2, all participants, irrespective of being in the active or sham arm, demonstrated a statistically significant difference (Cohen&amp;rsquo;s d &gt; 0.8) in pain and associated parameters such as depression, anxiety, pain-related interference, burden, and disability (P &lt; 0.01). Transient mild local side effects such as burning, pain, and itching were noted, with no cognitive side effects reported. In conclusion, this novel HD-tDCS protocol is effective in reducing pain in patients with SSD-P, with sustained effects up to 1 week.

A comprehensive investigation of comorbidities of prolonged grief disorder in a bereaved inpatient psychiatric sample

Prolonged Grief Disorder (PGD) was recently added to ICD-11 and DSM-5-TR. Depression and Posttraumatic Stress Disorder (PTSD) are frequent comorbidities, but findings regarding comorbid somatoform disorder and personality disorders remain mixed and studies with severely impaired patients are scarce. It was therefore the objective of the present study to examine comorbidities of PGD in a bereaved inpatient psychiatric sample. We assessed N = 101 bereaved inpatients in a psychiatric hospital with clinical interviews and self-report questionnaires. We calculated differences between patients with and without a PGD-diagnosis in number and type of comorbid disorders as well as associations between the severity of PGD and comorbid disorders. On average, patients had 2.53 comorbid psychiatric diagnoses. Patients with and without a PGD-diagnosis did not differ in their number of comorbid diagnoses, and there was no association between number of comorbid diagnoses and PGD-severity. However, patients with PGD, had significantly more comorbid diagnoses belonging to neurotic-, stress-related and somatoform disorders of the ICD-10. Patients with PGDICD-11 also had significantly higher scores in self-reported depressive, PTSD-, and somatoform symptoms, as well as the negative affectivity personality domain than those without a PGD diagnosis. To the best of our knowledge, this is the first study to provide insights into comorbidities of PGD in a bereaved inpatient psychiatric sample. It highlights the importance of considering PGD symptoms as part of the complaints of bereaved patients to achieve a tailored treatment approach. Future longitudinal studies are needed to unveil relationships between pre-existing mental disorders and PGD.
