Abstract
BACKGROUND Borderline personality disorder (BPD) is a serious disorder with a lifetime prevalence of 2.7-5.9% and is thought to correlate with altered neuroplasticity. The aim of the present study is to investigate possible associations of BPD (-severity) and alterations in neurological soft signs (NSS) and olfactory function. METHODS For the monocentric observational study, 39 female subjects with a BPD diagnosis and 19 female healthy control subjects were recruited. The groups were matched by age. Olfactory functions were examined using Sniffin' Sticks. NSS were assessed by a standardized test with 50 items. RESULTS BPD subjects have higher NSS scores in group comparison. By contrast, there are no alterations in the total score of olfactory function, while the BPD subjects scored higher in smell identification. Within the BPD group, the total NSS score was discovered to have a negative correlation with olfactory function. BPD subjects taking antipsychotics show more NSS than those without. We found no significant influence of posttraumatic stress disorder on the NSS or olfactory function. The BPD-severity correlates with NSS. LIMITATIONS Due to the cross-sectional design, we did not have a follow up examination. The sample size was small, and all patients had psychiatric comorbidities. Additionally, we did not perform MRI to connect our findings with possible structural abnormalities. CONCLUSIONS Our study confirmed altered NSS in BPD patients, whereas no impairment in the olfactory function was found. Further research is required to establish NSS and smell tests as clinical screening tools in BPD patients and to uncover the disorder's impact on neuroplasticity.

Vijayapriya CV, Tamarana R. Effectiveness of internet-delivered dialectical behavior therapy skills training on executive functions among college students with borderline personality traits: a non-randomized controlled trial. RESEARCH IN PSYCHOTHERAPY (MILANO) 2023; 26:694.

Abstract
Given the enormous influence of emotions on cognitive processes, individuals with borderline personality disorder (BPD) suffer from marked deficits in higher-order thinking abilities. Considering the prevalence of BPD among college students, this study aimed to investigate the changes in perceived executive functioning among college students with traits/presence of BPD undergoing internet-delivered dialectical behavior therapy skills training (DBT-ST) that included the mindfulness and emotion regulation modules. An internet-delivered version of DBT-ST was opted for, as technological advancements in the present era promote the use of online platforms for psychotherapy. This non-randomized controlled trial consisted of 36 college students with traits/presence of BPD. The intervention group attended 13 sessions of DBT-ST, and the control group attended 13 sessions of behavioral activation. Perceived executive functioning was assessed using the Behavior Rating Inventory of Executive Functions for Adults. A 2-way repeated measures analysis of variance was used to evaluate the treatment impact on the outcome variable. Results showed that the DBT-ST group had larger improvements in their abilities to initiate, plan, and organize current and future-oriented task demands and to organize their everyday environment, compared to the control group. Both, the DBT-ST group and the control group demonstrated improvements in emotional control, working memory, and their abilities to shift and task monitor. Findings suggest that the internet-delivered version of DBT-ST, consisting of the mindfulness and emotion regulation modules, can foster notable improvements in executive functions among college students with traits/presence of BPD. Improved executive functioning is one of the several multifaceted outcomes of dialectical behavior therapy.

Abstract
Very few studies have focused on the relationship between cognitive functions and clinical features in borderline personality disorder (BPD). Subjects with BPD and healthy controls were administered the Repeatable Battery for the Assessment of Neuropsychological Status, Trail Making Test A and B, and the Wisconsin Card Sorting Test. The Brief Symptom Inventory (BSI-53) was used to assess the severity of current symptoms. Attachment style was assessed with the Experiences in Close Relationship Questionnaire, identity integration with the Personality Structure Questionnaire, and other domains of personality dysfunction with the RUDE Scale for Personality Dysfunction. Patients with BPD performed significantly worse than healthy controls in all cognitive domains. Cognitive functions, particularly delayed memory and visuospatial abilities, displayed meaningful associations with trait-like clinical features, above the effect of global cognition and state psychopathology. These findings highlight the need to evaluate effects of cognitive rehabilitation on trait features among individuals with BPD.

Abstract
Abstract
Background
Borderline personality disorder (BPD) is a severe psychiatric disorder with multiple psychopathological domains; so studying the correlation of clinical or behavioral data with underlying structural and functional neurological findings in BPD is the focus of interest in recent years.
The aim of our study was to compare the presence of neurological soft signs (NSS) in patients with borderline personality disorder with their presence in normal controls, and to correlate the severity of different symptoms of BPD with the presence of NSS through a case-control study which was conducted on 30 patients and 30 matching controls recruited from Al Kasr Al Ainy Hospital, Cairo University, Egypt. All subjects were assessed by the Borderline Personality Questionnaire, the Barratt Impulsivity Scale-11, the Brief Non-Suicidal Self-Injury Assessment tool, and the Cambridge Neurological Inventory.
Results
The BPD group had significantly higher total NSS scores, primitive reflexes subscale score, and sensory integration subscale scores. There was also a positive correlation between NSS and overall severity of borderline symptoms.
Conclusions
The increased rates of NSS were associated with specific clinical symptoms in BPD including suicidality, self-harm, emptiness, and quasi-psychosis. Impulsivity was found to have the highest correlation with NSS.

Abstract
AbstractContemporary theories for the aetiology of borderline personality disorder (BPD) take a lifespan approach asserting that inborn biological predisposition is potentiated across development by environmental risk factors. In this review, we present and critically evaluate evidence on the neurobiology of BPD in childhood and adolescence, compare this evidence to the adult literature, and contextualise within a neurodevelopmental framework. A systematic review was conducted to identify studies examining the neurobiological (i.e. genetic, structural neuroimaging, neurophysiological, and neuropsychological) correlates of BPD symptoms in children and adolescents aged 19 years or under. We identified, quality assessed, and narratively summarised 34 studies published between 1980 and June 2016. Similar to findings in adult populations, twin studies indicated moderate to high levels of heritability of BPD, and there was some evidence for gene-environment interactions. Also consistent with adult reports is that some adolescents with BPD demonstrated structural (grey and white matter) alterations in frontolimbic regions and neuropsychological abnormalities (i.e. reduced executive function and disturbances in social cognition). These findings suggest that neurobiological abnormalities observed in adult BPD may not solely be the consequence of chronic morbidity or prolonged medication use. They also provide tentative support for neurodevelopmental theories of BPD by demonstrating that neurobiological markers may be observed from childhood onwards and interact with environmental factors to increase risk of BPD in young populations. Prospective studies with a range of repeated measures are now required to elucidate the temporal unfurling of neurobiological features and further delineate the complex pathways to BPD.

Abstract
The current study was designed to explore the specific relationship between neurologic soft signs (NSSs) and characteristics of antisocial personality traits in adolescents, and to investigate particular NSSs linked to certain brain regions in adolescents with antisocial personality traits. The research was conducted on 96 adolescents diagnosed with ASP traits (ASP trait group) using the ASPD subscale of the Personality Diagnostic Questionnaire for the DSM-IV (PDQ-4+) and 96 adolescents without traits of any personality disorder (control group). NSSs were assessed using the soft sign subscales of the Cambridge Neurological Inventory. Adolescents with ASP traits showed more motor coordination, sensory integration, disinhibition, and total NSSs than the control group. Seven NSSs, including stereognosia in right hand, finger agnosia and graphesthesia in both hands, left-right orientation, and go/no go stimulus, were significantly more frequent in teenagers with ASP traits. Sensory integration was positively associated with ASP traits. Adolescents with antisocial personality traits might have abnormalities in the central nervous system, and sensory integration might be the particular indicator of antisocial personality disorder.

Abstract
OBJECTIVE Neurological soft signs (NSSs) may reflect neurodevelopmental anomalies in association with the spectrum of schizophrenia disorders. We examined NSSs in Chinese adolescents with schizophrenia and schizotypal personality traits. METHODS Eighty-seven schizophrenic adolescents (SCH group), 85 adolescents with only schizotypal personality traits (SPT group), and 88 healthy controls (HC group) were enrolled. The NSS subscales of the Cambridge Neurological Inventory (CNI) were administered to all 260 participants. RESULTS The NSS prevalence rates were higher in the SCH group than in the other two groups for both hands in the fist-edge-palm, Oseretsky, and graphesthesia tests. Relative to HCs, the SCH group also showed higher NSS prevalence rates in the right finger agnosia and right mirror movement of finger opposition tests. SCH>SPT>HC trends were observed for all NSS subscale scores and for the left, right, and total NSS scores. CONCLUSIONS To our knowledge, the present study is the first to examine NSSs in adolescents with schizophrenia and adolescents with schizotypal personality traits. These results provide preliminary findings suggesting that schizophrenia spectrum disorders may be characterized by developmental abnormalities in the central nervous system, and support the notion that NSSs may be schizophrenia spectrum disorder biomarkers.
