Burden of post-traumatic stress disorder in postgenocide Rwandan population following exposure to 1994 genocide against the Tutsi: A meta-analysis

New social identities in Ukrainian 'refugees': A social cure or social curse?

Experiencing traumatic events often drives profound post-traumatic stress (PTS), but trauma also has the potential to engender positive consequences, such as post-traumatic growth (PTG). Traumatic experiences may also lead to gaining new identities which can have both protective (i.e., social cure) or damaging (i.e., social curse) effects on health and well-being. This study aims to examine the role of new social identities and related social identity resources acquired after war-related experiences (i.e., identification with a new host society and identification as a refugee) in contributing to different trauma trajectories. The sample included 468 participants who left Ukraine due to the war that commenced on February 24th, 2022, and became residents of Ireland or Poland. The findings indicate that identification with the host society was associated with lower PTS and greater PTG. Whereas identification with refugees was related to higher PTS, but it was not directly associated with PTG. Further, the psychological resources derived from these new identities mediated the relationship between identification strength and PTG. This study offers practical insights for interventions targeting refugees in their new countries of residence.

Help-seeking patterns and level of care for individuals with bipolar disorder in Rwanda

Most descriptive data on individuals with bipolar disorder originate from high-resource settings. Very little is known about the accessibility and service provision of intensive mental health care to persons living with bipolar disorder in low-resource settings. This information is needed to inform health systems and guide practitioners to improve standard treatment options and access to treatment. This cross-sectional study explored the level of care for outpatients with bipolar disorder and their help-seeking patterns at the two national referral hospitals in Rwanda. The study found that the majority, 93%, of outpatients with bipolar disorder in Rwanda were on prophylactic psychopharmacological treatment, but mainly first-generation antipsychotics and just 3% received lithium treatment. Furthermore, there was a lack of psychosocial intervention; consequently, 44% were not aware that they had bipolar disorder. Moreover, 1 in 5 participants utilized or had previously used traditional medicine. Awareness of own diagnostic status was not associated with educational level or use of traditional medicine. The study's sample size of 154 patients is relatively small, and the cross-sectional design does not provide causal inferences. The results demonstrate a considerable unmet need for improved mental health care services for individuals with bipolar disorder in Rwanda, including access to optimal medication and psychosocial interventions. Psychoeducation could be a possible starting point for improving the standard of care, informing the individual on their diagnosis and medication while empowering them to engage in their treatment plan.

Stressors related to the Covid-19 pandemic, climate change, and the Ukraine crisis, and their impact on stress symptoms in Germany: analysis of cross-sectional survey data

BACKGROUND

Climate change, the Covid-19 pandemic, and the Ukraine crisis are considered unprecedented global stressors, potentially associated with serious health consequences. However, simultaneous effects of these stressors are not yet understood, making it difficult to evaluate their relative contribution to the population burden and potential future manifestations in clinically significant psychiatric disorders. This study aimed at disentangling the relative contribution of the three stressor groups on current sub-clinical stress symptoms.

METHODS

A cross-sectional, representative survey study was conducted two months after the outbreak of the Ukraine war in Germany. Proportional quota sampling was applied for age, gender, income, and regional characteristics. Data were recruited by means of an online survey. 3094 data sets (1560 females) were included. Age ranged from 18-89 (M: 50.4 years; SD: 17.2). The Subclinical Stress Questionnaire (SSQ-25) served as main outcome measure. In collaboration with a professional media agency, 20 items were generated to capture salient population stressors. A three-factor exploratory structural equation model confirmed the appropriateness of this scale.

RESULTS

(1) Differences in subjective rankings revealed that stressors related to the Ukraine crisis were rated as most worrying, followed by climate change, and the Covid-19 pandemic (Generalized-Linear-Model: Epsilon = .97; F(1.94, 6001.14) = 1026.12, p < .001; η_p² = .25). (2) In a linear regression model (R² = .39), Covid-19 pandemic stressors were the only meaningful predictors for current ill-health (standardized β = .48). Ukraine crisis did not predict stress symptom profiles in the present sample. (3) Older and male individuals report less and/or less severe stress symptoms, although effect sizes were small (range: η² .11-.21). An older age also reduced the impact of Covid-19 stressors.

CONCLUSIONS

Researchers from the health sciences must consider overlapping effects from population stressors. Although the Ukraine crisis and climate change mark salient stressors, including economic threats, the Covid-19 pandemic still has a profound effect on ill-health and must be considered as a relevant factor in future manifestations of psychiatric and associated health consequences.

Community engagement in epigenomic and neurocognitive research on post-traumatic stress disorder in Rwandans exposed to the 1994 genocide against the Tutsi: lessons learned

Epigenomic and neurocognitive studies have provided new perspectives on post-traumatic stress disorder and its intergenerational transmission. This article outlines the lessons learned from community engagement (CE) in such research on Rwandan genocide survivors. A strong trauma-related response was observed within the research project-targeted community (genocide survivors) during explanation of the project. CE also revealed privacy concerns, as community members worried that any leakage of genetic/(epi)genomic data could affect not only themselves but also their close relatives. Adopting a culture of CE in the process of research implementation enables the prioritization of targeted community needs and interests. Furthermore, CE has stimulated the development of mental healthcare interventions, which married couples can apply to protect their offspring and thus truly break the cycle of inherited vulnerability.

Neurofeedback with low-cost, wearable electroencephalography (EEG) reduces symptoms in chronic Post-Traumatic Stress Disorder

BACKGROUND

The study examines the effectiveness of both neurofeedback and motor-imagery brain-computer interface (BCI) training, which promotes self-regulation of brain activity, using low-cost electroencephalography (EEG)-based wearable neurotechnology outside a clinical setting, as a potential treatment for post-traumatic stress disorder (PTSD) in Rwanda.

METHODS

Participants received training/treatment sessions along with a pre- and post- intervention clinical assessment, (N = 29; control n = 9, neurofeedback (NF, 7 sessions) n = 10, and motor-imagery (MI, 6 sessions) n = 10). Feedback was presented visually via a videogame. Participants were asked to regulate (NF) or intentionally modulate (MI) brain activity to affect/control the game.

RESULTS

The NF group demonstrated an increase in resting-state alpha 8-12 Hz bandpower following individual training sessions, termed alpha 'rebound' (Pz channel, p = 0.025, all channels, p = 0.024), consistent with previous research findings. This alpha 'rebound', unobserved in the MI group, produced a clinically relevant reduction in symptom severity in NF group, as revealed in three of seven clinical outcome measures: PCL-5 (p = 0.005), PTSD screen (p = 0.005), and HTQ (p = 0.005).

LIMITATIONS

Data collection took place in environments that posed difficulties in controlling environmental factors. Nevertheless, this limitation improves ecological validity, as neurotechnology treatments must be deployable outside controlled environments, to be a feasible technological treatment.

CONCLUSIONS

The study produced the first evidence to support a low-cost, neurotechnological solution for neurofeedback as an effective treatment of PTSD for victims of acute trauma in conflict zones in a developing country.

Global burden of post-traumatic stress disorder and major depression in countries affected by war between 1989 and 2019: a systematic review and meta-analysis

Objective

Extensive research has demonstrated high prevalences of post-traumatic stress disorder (PTSD) and major depression (MD) in war-surviving populations. However, absolute estimates are lacking, which may additionally inform policy making, research and healthcare. We aimed at estimating the absolute global prevalence and disease burden of adult survivors of recent wars (1989–2019) affected by PTSD and/or MD.

Methods

We conducted a systematic literature search and meta-analysis of interview-based epidemiological surveys assessing the prevalence of PTSD and/or MD in representative samples from countries with a recent war history (1989–2019). Drawing on the war definition and geo-referenced data of the Uppsala Conflict Database Programme and population estimates of the United Nations for 2019, we extrapolated the meta-analytic results to absolute global numbers of affected people. Drawing on disability-adjusted life years (DALYs) data of the Global Burden of Diseases Study 2019, we further calculated the PTSD-associated and MD-associated DALYs.

Results

Twenty-two surveys (N=15 420) for PTSD, 13 surveys for MD (N=9836) and six surveys on the comorbidity of PTSD and MD (N=1131) were included. Random effects meta-analyses yielded point prevalences of 26.51% for PTSD and 23.31% for MD. Of those affected by PTSD, 55.26% presented with comorbid MD. Prevalence rates were not significantly associated with war intensity and length, time since war, response rate or survey quality. The extrapolation yielded 316 million adult war-survivors globally who suffered from PTSD and/or MD in 2019. War-survivors were almost exclusively living in low/middle-income countries (LMICs) and carried a burden of 3 105 387 and 4 083 950 DALYs associated with PTSD and MD, respectively.

Conclusions

Since LMICs lack sufficient funding and qualified professionals to provide evidence-based psychological treatments for such large numbers of affected people, alternative and scalable strategies using existing resources in primary care and communities are required. Research is required to assist upscaling.

Role of Community Resiliency Model Skills Trainings in Trauma Healing Among 1994 Tutsi Genocide Survivors in Rwanda

Background

Mental health among survivors of the 1994 Tutsi genocide in Rwanda remains poor, even after multiple efforts to assist those recovering from this trauma. The Community Resilience Model (CRM) is a biologically based set of skills that can be delivered in community settings by trained lay persons and has shown to significantly improve mental health in a number of settings and populations, though it has not been used with genocide survivors in Rwanda. This study assessed if the CRM training was able to improve mental health among genocide survivors.

Methods

A quasi-experimental design was used to evaluate the CRM intervention among Tutsi genocide survivors from the Huye, Nyamagabe and Nyaruguru districts in Southern Rwanda. Consenting participants completed a questionnaire before and six months after the training to assess their level of trauma, secondary traumatic stress, depression and skills to teach CRM skills to others.

Results

The findings revealed significant improvements across all trauma symptoms between the intervention and control group (t = 37, p<0.001). The CRM trainings also resulted in significant within-person declines of depressive symptoms (p < 0.001), perceived secondary traumatic stress (p = 0.003) and trauma-related symptoms (p = 0.002). Training participants also reported significant increases in perceived CRM benefits and satisfaction (p < 0.001).

Conclusion

The CRM intervention was found to be effective for improving mental health in 1994 Tutsi genocide survivors. Since CRM can be delivered by trained persons to groups of persons in community settings, it has a high potential for successful broader implementation and sustainability, which is critically important in an environment with few mental health resources.

Intergenerational trauma transmission is associated with brain metabotranscriptome remodeling and mitochondrial dysfunction

Intergenerational trauma increases lifetime susceptibility to depression and other psychiatric disorders. Whether intergenerational trauma transmission is a consequence of in-utero neurodevelopmental disruptions versus early-life mother–infant interaction is unknown. Here, we demonstrate that trauma exposure during pregnancy induces in mouse offspring social deficits and depressive-like behavior. Normal pups raised by traumatized mothers exhibited similar behavioral deficits to those induced in pups raised by their biological traumatized mothers. Good caregiving by normal mothers did not reverse prenatal trauma-induced behaviors, indicating a two-hit stress mechanism comprising both in-utero abnormalities and early-life poor parenting. The behavioral deficits were associated with profound changes in the brain metabotranscriptome. Striking increases in the mitochondrial hypoxia marker and epigenetic modifier 2-hydroxyglutaric acid in the brains of neonates and adults exposed prenatally to trauma indicated mitochondrial dysfunction and epigenetic mechanisms. Bioinformatic analyses revealed stress- and hypoxia-response metabolic pathways in the neonates, which produced long-lasting alterations in mitochondrial energy metabolism and epigenetic processes (DNA and chromatin modifications). Most strikingly, early pharmacological interventions with acetyl-L-carnitine (ALCAR) supplementation produced long-lasting protection against intergenerational trauma-induced depression.

Sammy Alhassen, Siwei Chen, et al. use mouse models to examine the effects of prenatal and postnatal stress on metabolomic and transcriptomic pathways in the brain. Their results suggest that altered mitochondrial metabolism may underlie trauma-induced behavioral deficits, and that correcting metabolism with ALCAR supplementation may protect against intergenerational transmission of traumatic stress.

Societal Healing in Rwanda: Toward a Multisystemic Framework for Mental Health, Social Cohesion, and Sustainable Livelihoods among Survivors and Perpetrators of the Genocide against the Tutsi

The genocide against the Tutsi in Rwanda left the country almost completely devastated, with tremendous consequences for mental health, social cohesion, and livelihoods. In the aftermath of such extreme circumstances and human rights violations, societal healing should be conceptualized and approached based on a multisystemic framework that considers these three sectors-mental health, social cohesion, and livelihoods-as well as their interactions. The aims of the present study are twofold: (1) to review evidence on multisystemic healing initiatives already applied in Rwanda using fieldwork notes from interviews and focus groups, alongside relevant scholarly and gray literature, and (2) to propose a scalable multisystemic framework for societal healing in Rwanda that builds on existing innovations. Within a participatory action research methodology, we used a grounded theory approach to synthesize fieldwork findings and compare them with literature to generate a set of principles for multisystemic recovery in Rwanda. Recognizing the strengths and limitations of the current mental health system and other initiatives, including sociotherapy and collaborative livelihood projects, we propose a scalable and rights-based multisystemic approach for recovery and resilience that would target mental health, social cohesion, and sustainable livelihoods within an integrative cross-sectoral framework, thus reducing the risk of post-genocide conflict.

Prevalence and correlates of depression among rural and urban Rwandan mothers and their daughters 26 years after the 1994 genocide against the Tutsi

BACKGROUND

In the past 26 years since the genocide against the Tutsi, mental illness continues to be the greatest challenges facing the Rwandan population. In the context of the 1994 genocide against Tutsi, there are three different survival status within Rwandan women. Those who were targeted by the genocide referred to as 'survivors', those who were in the country during the genocide but were not targeted referred to as 'non-targeted', and those who were outside the country referred to as '1959 returnees'. All these groups experienced the traumatic events differently. The literature shows that traumatic stress exposure is associated with depression.

OBJECTIVES

To demonstrate differences in trauma exposure in a sample of mothers and daughters according to their genocide survival status. To examine differences in depression prevalence between these three groups of mothers and daughters as a function of their genocide survival status and place of residence. To examine the relationship between major depression, survival status, place of residence, and trauma exposure in sample of mothers and daughters, including the relationship between mothers' depression and daughters' depression.

METHODS

A sample of 309 dyads of mothers and daughters was recruited. Data were collected using the Mini International Neuropsychiatric Interview, Life Events Questionnaire and the Social Demographics Questionnaire. Data were analysed using descriptive statistics, chi-square test, logistic regression, and one-way ANOVA.

RESULTS

There is a significant difference in trauma exposure in three survival categories of mothers and daughters. A 23% of mothers and 18.4% of daughters met criteria for major depression, with urban participants twice as likely to meet criteria as participants from rural areas. Depression was associated with trauma exposure and place of residence in mothers' and daughters' samples. Maternal depression was associated with depression in daughters.

CONCLUSIONS

Family support counselling services and research to identify factors of intergenerational depression are needed.
