Loneliness, influenced by genetic and environmental factors such as childhood maltreatment, is one aspect of interpersonal dysfunction in Borderline Personality Disorder (BPD). Numerous studies link loneliness and BPD and twin studies indicate a genetic contribution to this association. The aim of our study was to investigate whether genetic predisposition for loneliness and BPD risk overlap and whether genetic risk for loneliness contributes to higher loneliness reported by BPD patients, using genome-wide genotype data. We assessed the genetic correlation of genome-wide association studies (GWAS) of loneliness and BPD using linkage disequilibrium score regression and tested whether a polygenic score for loneliness (loneliness-PGS) was associated with case-control status in two independent genotyped samples of BPD patients and healthy controls (HC; Witt2017-sample: 998 BPD, 1545 HC; KFO-sample: 187 BPD, 261 HC). In the KFO-sample, we examined associations of loneliness-PGS with reported loneliness, and whether the loneliness-PGS influenced the association between childhood maltreatment and loneliness. We found a genetic correlation between the GWAS of loneliness and BPD in the Witt2017-sample (rg = 0.23, p = 0.015), a positive association of loneliness-PGS with BPD case-control status (Witt2017-sample: NkR² = 2.3%, p = 2.7*10; KFO-sample: NkR² = 6.6%, p = 4.4*10), and a positive association between loneliness-PGS and loneliness across patient and control groups in the KFO-sample (β = 0.186, p = 0.002). The loneliness-PGS did not moderate the association between childhood maltreatment and loneliness in BPD. Our study is the first to use genome-wide genotype data to show that the genetic factors underlying variation in loneliness in the general population and the risk for BPD overlap. The loneliness-PGS was associated with reported loneliness. Further research is needed to investigate which genetic mechanisms and pathways are involved in this association and whether a genetic predisposition for loneliness contributes to BPD risk.

Review
Borderline personality disorder (BPD) is a severe mental illness marked by unpredictable feelings, behaviors, and relationships. Symptoms like emotional instability, impulsivity, and poor social connections are the basis for diagnostic criteria. A noteworthy discovery highlights the clinical overlap between BPD and several psychotic disorders by arguing that BPD and psychotic symptoms raise the risk of psychopathology. According to neuroimaging evidence, structural and functional brain changes, notably in regions controlling affective regulation and impulse control, are seen in BPD patients. Adolf Stern, a psychoanalyst, used the word "borderline" in 1938 to describe patients who exhibited increased symptoms during therapy and displayed masochistic tendencies. Modern BPD research has highlighted the complexity of symptoms like boredom, a former diagnostic criterion associated with feelings of emptiness. Though there are still unanswered problems regarding its precise, practical components, the treatment technique known as Schema therapy (ST) has shown promise in treating BPD. It's interesting to note that BPD displays complex relationships with other illnesses; for instance, some neurochemical pathways coincide with those in bulimia nervosa, pointing to a deeper level of interconnection. Concerning diagnosis, BPD's defining symptoms include, among others, the fear of abandonment, identity disruption, and recurrent suicidal conduct. The range of treatment options includes pharmacological interventions and psychotherapies like dialectical behavior therapy (DBT). Even though antidepressants like selective serotonin reuptake inhibitors (SSRIs) are routinely prescribed, research on their efficacy is ongoing, underlining the significance of thorough treatment planning. In conclusion, BPD continues to be a complex condition that calls for early detection, especially considering that it usually manifests in adolescence. While many patients report symptom relief, lingering problems still exist, emphasizing the value of comprehensive and personalized treatment strategies.

Review
Personality disorders in homeless people pose a challenge to the medical community and society, requiring specialized approaches for these super-difficult patients. The prevalence of personality disorders is higher in homeless populations than in the general population. However, there is a knowledge gap regarding personality disorders among people experiencing homelessness, and the implications of this lack of recognition are substantial. This paper provides a brief narrative review of personality disorders among homeless individuals. The primary importance and specificity of these disorders in this population remain unexplored. We searched PubMed and Web of Science databases in February and November 2023 using the keywords 'homeless' and 'personality disorder', and selected fifty-eight studies to be included in this literature review. The main themes of the results were personality disorders in homeless individuals and comorbid psychiatric disorders; risk factors and other psychological and behavioral data; clinical and intervention outcomes; and challenges linked to assessment, treatment, and intervention. The homeless population experiences significant diagnostic variability and the diagnosis of personality disorders is still evolving, contributing to difficulties in diagnosis, assessment, and treatment. A future challenge is to raise clinical awareness and optimize research knowledge, assessment, and intervention in personality disorders among homeless individuals with comorbid psychiatric disorders.

BACKGROUND
Recent literature has shown that a considerable percentage of patients with severe mental disorders can develop, over time, full-blown or subthreshold catatonia. Some studies corroborate the model of an illness trajectory in which different mental disorders would be arranged along a continuum of severity until the development of catatonia. In such an illness pathway, autistic traits (AT) and borderline personality disorder (BPD) may represent important steps. In order to further explore the association between AT, BPD, and catatonia, the aim of this study was to compare catatonic spectrum symptoms and AT among patients with major depressive disorder (MDD), BPD, and healthy controls (CTL), also evaluating possible predictive dimensions of the different diagnoses.
METHODS
A total of 90 adults affected by BPD, 90 adults with a diagnosis of MDD, and 90 CTL, homogeneous in terms of gender and age, were recruited from six Italian university departments of psychiatry and assessed with the SCID-5-RV, the Catatonia Spectrum (CS), and the Adult Autism Subthreshold Autism Spectrum (AdAS Spectrum).
RESULTS
The total CS score was significantly higher in the BPD and MDD groups than in the CTL group, while the majority of CS domain scores were significantly higher in the BPD group than in the MDD group, which scored significantly higher than the CTL group. The total AdAS Spectrum score and the AdAS Spectrum domain scores were significantly higher in the BPD group than in the MDD group, which in turn scored significantly higher than the CTL group. The CS domains "psychomotor activity" and "impulsivity", and AdAS Spectrum domains "verbal communication", "empathy", and "hyper-/hyporeactivity to sensory input" were associated with the risk of presenting a diagnosis of BPD.

INTRODUCTION
Population studies on social anxiety disorder (SAD) are relatively scarce and there is no previous reported evidence on prevalence or correlates of SAD in an Andalusian general population sample.
MATERIAL AND METHODS
We used a random representative sample previously identified via standard stratification procedures. Thus, a final sample of 4507 participants were included (response rate 83.7%). Interviewees were thoroughly assessed on sociodemographic, clinical and psychosocial factors, including: exposures to threatening life events (TLEs), childhood abuse, personality disorder and traits (neuroticism, impulsivity, paranoia), global functioning, physical health and toxics consumption. SAD diagnosis was ascertained using the Mini International Neuropsychiatric Interview. Both, pooled prevalences (with 95% confidence intervals) and risk correlates for SAD were estimated using binary logistic regression.
RESULTS
Estimated prevalence for SAD was 1.1% (95% CI=0.8-1.4). Having a SAD diagnosis was independently and significantly associated with younger age, poorer global functioning, higher neuroticism and paranoia personality traits, having suffered childhood abuse and exposure to previous TLEs. Furthermore, SAD was significantly associated with comorbid personality disorder, major depression, panic disorder and alcohol abuse.
CONCLUSIONS
Among this large Andalusian population sample, the prevalence of SAD and its associated factors are relatively similar to previously reported international studies, although no population study had previously reported such a strong association with paranoia.

Review
Prior studies have identified that mentally healthy people tend to share common characteristics and common ways of coping with stressful life events; they show similar patterns of behavior and more flexible and adaptive social roles. The objectives of the study are to assess the influence of personality factors on gender roles and mental health, to identify personality patterns along with gender roles, and to assess the influence of the patterns identified on mental health. Data collection from a sample of 795 university students was carried out during 2019. Multilevel analyses tested the associations between gender (BSRI) and personality (TIPI) and between personality and health -mental health (GHQ12) and wellbeing (MHC-SF). Cluster analysis explored tendencies of gender and personality, and each cluster showed different health patterns. Individuals with high scores in extraversion, conscientiousness, emotional stability, openness to experience, and very high agreeableness score, as well as high femininity and masculinity scores, presented a decreased psychological morbidity (β= -3.62, 0.57 (SE), p<0.001) and an increased well-being (β=7.68, 1.15 (SE), p<0.001). The most relevant indicators of mental health were identified in androgynous individuals, those individuals with high scores in masculinity and femininity, as well as high scores in extraversion, openness to experience, emotional stability, agreeableness, and conscientiousness.

Review
Over the past two decades noninvasive brain stimulation (NIBS) techniques have emerged as powerful therapeutic options for a range of psychiatric and neurological disorders. NIBS are hypothesized to rebalance pathological brain networks thus reducing symptoms and improving functioning. This development has been fueled by controlled studies with increasing size and rigor aiming to characterize how treatments induce clinically effective change. Clinical trials of NIBS for specific indications have resulted in federal approval for unipolar depression, bipolar depression, smoking cessation, and obsessive-compulsive disorder in the United States, and several other indications worldwide. As a rapidly emerging field, there are numerous pre-clinical indications currently in development using a variety of electrical and magnetic, non-convulsive, and convulsive approaches. This review discusses the state-of-the-science surrounding promising avenues of NIBS currently in pre-approval stages for non-affective psychiatric disorders. We consider emerging therapies for psychosis, anxiety disorders, obsessive-compulsive disorder, and borderline personality disorder, utilizing transcranial magnetic stimulation (TMS), transcranial direct current stimulation (tDCS), and magnetic seizure therapy (MST), with an additional brief section for early-stage techniques including transcranial focused ultrasound stimulation (tFUS) and transcranial alternating current stimulation (tACS). As revealed in this review, there is considerable promise across all four psychiatric indications with different NIBS approaches. Positive findings are notable for the treatment of psychosis using tDCS, MST, and rTMS. While rTMS is already FDA approved for the treatment of obsessive-compulsive disorder, methodologies such as tDCS also demonstrate potential in this condition. Emerging techniques show promise for treating non-affective disorders likely leading to future regulatory approvals.

OBJECTIVE
As personality changes and personality disorders are frequently observed in multiple sclerosis (MS), personality may be a prognostic factor for this disease. The present study investigated the influence of personality on disability, progression, and treatment adherence in MS.
METHOD
Personality was assessed in 41 patients with Relapsing-Remitting MS (30 females; mean age = 42.63 years) using the NEO Personality Inventory-3rd edition. Disability was measured with the Expanded Disability Status Scale, and treatment adherence information was collected from the Swiss MS Cohort. Correlation, multiple linear and partial least square regressions were performed to examine relations between personality, disability, and treatment adherence in MS.
RESULTS
After accounting for age and time since disease onset, our analysis revealed that Neuroticism (β = 0.32, p = 0.01) and its Vulnerability facet (β = 0.28, p < 0.05) predicted greater disability, whereas Extraversion (β = -0.25, p = 0.04) and its Activity facet (β = -0.23, p < 0.05) predicted milder disability. Regarding disability progression, correlational analysis revealed that it was negatively correlated with Extraversion (r = -0.44, p = 0.02) and the Feelings facet of Openness (r = -0.41, p = 0.03), but regressions failed to highlight any predictive links. No significant results could be demonstrated for treatment adherence.
CONCLUSIONS
Overall, our study showed that some personality traits can impact disability in MS, indicating that these should be considered in clinical practice, as they could be used to adapt and improve patients' clinical support.

To examine the relationship between khat use disorder and antisocial personality disorder in newly admitted inmates in a correctional facility in Ethiopia. A cross-sectional study using successive sampling was conducted among 411 new inmates from April 20 to July 19, 2019. The Alcohol, Smoking, and Substance Involvement Screening Test was utilized to measure khat use. diagnostic criteria were used to identify antisocial personality disorder. Environmental, criminal, and clinical backgrounds of the inmates were also evaluated. The prevalence of current khat use and khat use disorder was 49.4% and 37%, respectively. The prevalence of khat use disorder among inmates with antisocial personality disorder was 76%. Inmates with antisocial personality disorder were twice as likely as those without antisocial personality disorder to have khat use disorder (adjusted odds ratio [AOR] = 2; 95% CI, 1.2-3.4). Punishment for misconduct in prior imprisonment (AOR = 3; 95% CI, 1.6-5.3), family history of alcohol use (AOR = 2; 95% CI, 1.3-3.5), and chronic physical illness (AOR = 5.3; 95% CI, 2.4-11.8) were significantly associated with khat use disorder. The prevalence of khat use disorder was higher among inmates with antisocial personality disorder, and antisocial personality disorder is linked to khat use disorder. The findings of this study suggest the need for the establishment of a mental health system in all prison institutions in Ethiopia to enhance early screening for underlying medical conditions, history of substance use, and antisocial personality disorder. Those inmates with identified substance use need detoxification therapy and motivational interviews after prison admission. .

BACKGROUND
Morningness (morning-eveningness preference or chronotypes) and personality can be both associated with well-being, but few studies have directly compared these two constructs as correlates of well-being. Thus, the first purpose of this study was to test the effects of interactions between stable personality traits (temperaments) and morningness on well-being. Furthermore, personality factors are often composed of both stable biological factors (temperament) and socio-cultural factors (character), and little is known about personality interplay of temperament and character factors with respect to morningness and well-being. The second purpose of this study was therefore to examine the sequential mediating effects of temperament and character factors on the relationship between morningness and well-being.
METHODS
The Composite Scale of Morningness, the Korean version of the Temperament and Character Inventory-Revised Short Version (TCI-RS), and the Satisfaction with Life Scale were used to measure morningness, personality dimensions, and well-being, respectively, in 287 Korean university students. Moderating and sequentially mediating effects of temperament and character traits were determined using Hayes' PROCESS macro in SPSS after controlling for sex and age.
RESULTS
First, novelty-seeking (NS) and persistence (PS) temperaments have demonstrated the moderating effect in the association between morningness and well-being. The positive effects of morningness on life satisfaction increased with lower NS and PS, respectively. However, other temperaments such as harm avoidance (HA) and reward dependence (RD) have not shown the moderation in the relationship between morningness on well-being. Second, HA temperament and self-directedness (SD) character sequentially mediated the relationship between morningness and well-being. The combination of low scores of HA and high scores of SD have shown the positive effect on the relationship between morningness and well-being.
DISCUSSION
This study demonstrated that both the interactions between temperaments and morningness, and combination of specific TCI-RS temperament and character traits play important roles in influencing the association between morningness and well-being. The significance of the mature SD character and its implications for well-being are discussed with limitation of the present study.
