This EEG study aims at dissecting the differences in the activation of neural generators between borderline personality disorder patients with court-ordered measures (BDL-COM) and healthy controls in visual perspective taking. We focused on the distinction between mentalizing (Avatar) and non-mentalizing (Arrow) stimuli as well as self versus other-perspective in the dot perspective task (dPT) in a sample of 15 BDL-COM cases and 54 controls, all of male gender. BDL-COM patients showed a late and diffuse right hemisphere involvement of neural generators contrasting with the occipitofrontal topography observed in controls.

This high density EEG report dissects the neural processing in the visual perspective taking using four experimental comparisons (Arrow, Avatar and Self, Other). Early activation differences occurred between the Avatar and the Arrow condition in primary visual pathways concomitantly with alpha and beta phase locked responses predominant in the Avatar condition. In later time points, brain activation was stronger for the Avatar condition in paracentral lobule of frontal lobe.

Previous studies showed that neurotypical adults are able to engage in unconscious analyses of others' mental states in the context of automatic perspective taking and experience systematic difficulties when judging the conflicts between their own (Self) and another's (Other) perspective. Several functional MRI (fMRI) studies reported widespread activation of mentalizing, salience, and executive networks when adopting the Other compared to Self perspective. This study aims to explore whether cognitive and emotional parameters impact on brain reactivity in dot perspective task (dPT).

Article Synopsis
  • The study examined how inconsistencies in perspectives affected reaction times and error rates among 82 healthy adults using fMRI during a dot perspective task.
  • Findings indicated that the mentalizing (Avatar) task activated brain networks related to theory of mind (ToM), while the non-mentalizing (Arrow) task did not, highlighting a distinction between these two types of stimuli.
  • Inconsistent trials resulted in specific brain activations linked to self-other distinction and decision-making processes, suggesting that perceiving others' perspectives involves more complex neural mechanisms compared to one’s own perspective.

Background: Mental health professionals (MHP) working in court-mandated treatment settings face ethical dilemmas due to their dual role in assuring their patient's well-being while guaranteeing the security of the population. Clear practical guidelines to support these MHPs' decision-making are lacking, amongst others, due to the ethical conflicts within this field. This qualitative interview study contributes to the much-needed empirical research on how MHPs resolve these ethical conflicts in daily clinical practice.

Forensic psychiatry has often been neglected in nonwestern countries, including the African continent. Our aim was to assess the practices and needs for improvement in the field of forensic psychiatry in Rwanda. During a one-week visit conducted in October 2017, we interviewed key-informants working at decisional levels in the domains of health, justice and security.

The significant progress of psychiatry in the 20th century provided a sophisticated theoretical framework to analyze the complex relationships between crime and mental illness. Schizophrenia has been traditionally associated with severe cognitive and affective deficits that heavily influence empathy, judgment capacities, but also control of impulsiveness. Although there is an association between psychotic disorders and absence or decrease of legal responsibility, their relationship is also determined by sociodemographic, developmental, and clinical factors.

Background: We aimed to assess the opinion of primary care workers, social workers, translators and mental health caregivers who work with asylum seekers about the latter's unmet needs and barriers to access to mental healthcare.

Methods: We used a Likert scale to assess the opinion of 135 primary care workers (general practitioners, nurses, social workers and translators) and mental health caregivers about the proportion of asylum seekers with psychiatric disorders, their priority needs and their main barriers to mental health services.

Results: Insufficient access to adequate financial resources, poor housing and security conditions, access to employment, professional training and legal aid were considered as priority needs, as were access to dental and mental healthcare.

Background: Few studies investigated the long-term mental health outcome in culturally different post-conflict settings. This study considers two surveys conducted in Kosovo 8 years after the Balkans war and in Rwanda 14 years after the genocide.

Methods: All participants (n = 864 in Kosovo; n = 962 in Rwanda) were interviewed using the posttraumatic stress disorder (PTSD) and major depressive episode (MDE) sections of the Mini International Neuropsychiatric Interview (MINI) and the Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36).

Objective: To assess the importance of spirituality and religious coping among outpatients with a DSM-IV diagnosis of schizophrenia or schizoaffective disorder living in three countries.

Method: A total of 276 outpatients (92 from Geneva, Switzerland, 121 from Trois-Rivières, Canada, and 63 from Durham, North Carolina), aged 18-65, were administered a semi-structured interview on the role of spirituality and religiousness in their lives and to cope with their illness.

Results: Religion is important for outpatients in each of the three country sites, and religious involvement is higher than in the general population.

Objective: When potentially dangerous patients reveal criminal fantasies to their therapists, the latter must decide whether this information has to be transmitted to a third person in order to protect potential victims. We were interested in how medical and legal professionals handle such situations in the context of prison medicine and forensic evaluations. We aimed to explore the motives behind their actions and to compare these professional groups.

Hunger strike is a regularly reported problem in prison. Although clinical situations are rarely severe, hospitalisation is often considered. In consequence, it is not only physicians working in prisons, but also hospital medical teams who face challenges related to hunger strike, involving somatic, psychological, legal and human rights aspects.

We reviewed the medical records of the 118 adolescent detainees which had at least one consultation by a psychiatrist at the prison health facility during 2007. General practitioners used the International Classification of Primary Care (ICPC-2) for recording health problems. Psychiatrists used the International Classification of Diseases (ICD-10) for making psychiatric diagnoses.

Despite efforts to reduce coercion in psychiatry, involuntary hospitalizations remain frequent, representing more than half of all admissions in some European regions. Since October 2006, only certified psychiatrists are authorized to require a compulsory admission to our facility, while before all physicians were, including residents. The aim of the present study is to assess the impact of this change of procedure on the proportion compulsory admissions.

Purpose: To examine the socio-demographic determinants of post-traumatic stress disorder (PTSD) and its association with major depressive episode and self-perceived physical and mental health in a large random sample of the Rwandan population 14 years after the 1994 genocide.

Methods: Using the Mini International Neuropsychiatric Interview and Medical Outcomes Study 36-Item Short-Form (SF-36) translated in Kinyarwanda, we interviewed 1,000 adult residents from the five provinces of Rwanda. Socio-demographic data and specific somatic symptoms were also recorded.

Psychiatry is now subject to two apparently contradictory movements. On the one hand, the need to respect the autonomy and rights of patients is reinforced and coercive measures are strictly defined and limited. On the other hand, security concerns in our society leads to prosecution of psychiatric disorders, especially when accompanied by behavioral problems or criminal acts.

Religion and spirituality (RS) as a coping resource for facing stressful life events is encountered with increasing frequency in the medical literature. RS is associated with more favourable outcomes among people suffering from mental disorders. Detention is a stressful situation and the prevalence of mental disorders in places of detention is increased compared with the community.
