To examine if the COVID-19 pandemic was associated with a differential effect longitudinally in relation to its psychological and functional impact on patients with bipolar disorder and Emotionally Unstable Personality Disorder (EUPD).

Semi-structured interviews were conducted with 29 individuals attending the Galway-Roscommon Mental Health Services with an ICD-10 diagnosis of either bipolar disorder (n = 18) or EUPD (n = 11). The impact of the COVID-19 pandemic was assessed in relation to anxiety and mood symptoms, social and occupational functioning, and quality of life utilising psychometric instruments and Likert scale data, with qualitative data assessing participants’ subjective experiences.

Individuals with EUPD exhibited significant anxiety and depressive symptoms and increased hopelessness compared to individuals with bipolar disorder. Repeated measures data demonstrated no significant change in symptomatology for either the EUPD or bipolar disorder group over time, but demonstrated an improvement in social (t = 4.40, p < 0.001) and occupational functioning (t = 3.65, p = 0.03), and in quality of life (t = 4.03, p < 0.001) for both participant groups. Themes attained from qualitative data included the positive impact of the discontinuation of COVID-19 mandated restrictions (n = 19), and difficulties experienced secondary to reductions in the provision of mental health services during the COVID-19 pandemic (n = 17).

Individuals with EUPD demonstrated increased symptomatology over a two-year period compared to those with bipolar disorder. The importance of face-to-face mental health supports for this cohort are indicated, particularly if future pandemics impact the delivery of mental health services.

Borderline personality disorder (BPD) is a severe psychiatric disorder conceptualised as a disorder of emotion regulation. Emotion regulation has been linked to a frontolimbic network comprising the dorsolateral prefrontal cortex and the amygdala, which apparently synchronises its activity via oscillatory coupling in the theta frequency range.

To analyse whether there are distinct differences in theta oscillatory coupling in frontal brain regions between individuals with BPD and matched controls during emotion regulation by cognitive reappraisal.

Electroencephalogram (EEG) recordings were performed in 25 women diagnosed with BPD and 25 matched controls during a cognitive reappraisal task in which participants were instructed to downregulate negative emotions evoked by aversive visual stimuli. Between- and within-group time–frequency analyses were conducted to analyse regulation-associated theta activity (3.5–8.5 Hz).

Oscillatory theta activity differed between the participants with BPD and matched controls during cognitive reappraisal. Regulation-associated theta increases were lower in frontal regions in the BPD cohort compared with matched controls. Functional connectivity analysis for regulation-associated changes in the theta frequency band revealed a lower multivariate interaction measure (MIM) increase in frontal brain regions in persons with BPD compared with matched controls.

Our findings support the notion of alterations in a frontal theta network in BPD, which may be underlying core symptoms of the disorder such as deficits in emotion regulation. The results add to the growing body of evidence for altered oscillatory brain dynamics in psychiatric populations, which might be investigated as individualised treatment targets using non-invasive stimulation methods.

To examine the psychological and social impact of the COVID-19 pandemic on patients with established mood disorders during a period of stringent mandated social restrictions.

Semi-structured interviews were conducted with 36 individuals attending the Galway–Roscommon Mental Health Services with an International Statistical Classification of Diseases and Related Health Problems, tenth revision (ICD-10) diagnosis of either Bipolar Affective Disorder (BPAD) (n = 20) or Emotionally Unstable Personality Disorder (EUPD) (n = 16) in this cross-sectional study. We determined the impact of the COVID-19 restrictions on anxiety and depressive symptoms, impulsivity, thoughts of self-harm, social and occupational functioning and quality of life.

The COVID-19 pandemic deleteriously impacted mental health (56.3% v. 15.0%, χ2 = 7.42, p = 0.02), and mood (75.0% v. 20.0%, χ2 = 11.17, p = 0.002) to a greater extent in the EUPD compared to the bipolar disorder cohort, with 43.8% of individuals with EUPD reporting an increase in suicidal ideation. Psychometric rating scales [Beck Anxiety Inventory (BAI), Beck Depression Scale (BDS), Beck Hopelessness Scale (BHS), Barratt Impulsivity Scale (BIS)] and Likert scales for anxiety, mood and quality of life noted significantly higher levels of psychopathology in the EUPD cohort (p < 0.01). Qualitative analysis reflected quantitative data with themes of the employment of maladaptive coping mechanisms and reduced mental health supports notable.

Individuals with EUPD are experiencing significant mental health difficulties related to the COVID-19 pandemic. The provision and recommencement of therapeutic interventions to this cohort, in particular, are warranted given the significant distress and symptoms being experienced.

There is an abundant literature on the unfavourable attitudes held by staff working in mental health care settings towards patients with borderline personality disorder. The aim of this study was to assess whether attendance at a training session about the neurobiological underpinnings of borderline personality disorder could improve knowledge and produce positive attitudinal change within staff members working in a low secure inpatient setting.

Staff knowledge and attitudes (Mental Health Locus of Origin, Empathic Concern and Perspective Taking) were assessed at baseline, post-training attendance and at an eight-week follow up.

Attendance at the training session was associated with significant increases in theoretical knowledge, Perspective Taking and Locus of Origin scores. However, there were no changes observed in Empathic Concern scores.

This research suggests that a relatively brief training session, that utilises the neurobiological framework, can be effective in facilitating knowledge and attitudinal change for those working with borderline personality disorder. The implications of the findings are discussed along with suggestions for further research.

Brain-derived neurotrophic factor (BDNF) plays a critical role in brain plasticity processes and serum levels have been demonstrated to be altered in patients with different mental disorder including suicidal behaviour. The objective of this study was to examine the association between serum BDNF levels as a possible peripheral indicator of suicide behaviour in subjects suffering from depression, personality disorders (PDs) and adjustment disorders (ADs) with or without suicide attempt.

The research included 172 randomly selected individuals suffering from recurrent depressive disorder (RDD; F 33.2), emotionally unstable PD (F 60.3) and AD (F 43.2), with or without attempted suicide according to the criteria of the ICD-10 (International Statistical Classification of Diseases and Related Health Problems 10th Revision) and 60 phenotypically health control subjects. In the group of patients, 73% subjects took some form of psychopharmacotherapy. Serum BDNF levels were measured by enzyme linked immunosorbent assay.

Subjects with PD and AD with suicide attempts had significantly lower serum BDNF levels than those without suicide attempts. In groups of subjects with PD and AD, those taking psychopharmacotherapy had higher serum BDNF levels. In the group of subjects with RDD, there were no differences with respect to suicide attempts or psychopharmacotherapy. Logistical regression analysis was indicated that psychopharmcotherapy and serum BDNF levels statistically correlated with suicide attempts.

The lower levels of BDNF in subjects suffering from PD and AD with suicide attempts, suggest that the serum BDNF level is a potential marker of suicidal behaviour, independent of mental disorders.
