A survey of traditional and faith healers providing mental health care in three sub-Saharan African countries.

BACKGROUND: Traditional and faith healers constitute an important group of complementary and alternative mental health service providers (CAPs) in sub-Sahara Africa. Governments in the region commonly express a desire to integrate them into the public health system. The aim of the study was to describe the profile, practices and distribution of traditional and faith healers in three sub-Saharan African countries in great need for major improvements in their mental health systems namely Ghana, Kenya and Nigeria. MATERIALS AND METHODS: A mapping exercise of CAPs who provide mental health care was conducted in selected catchment areas in the three countries through a combination of desk review of existing registers, engagement activities with community leaders and a snowballing technique. Information was collected on the type of practice, the methods of diagnosis and the forms of treatment using a specially designed proforma. RESULTS: We identified 205 CAPs in Ghana, 406 in Kenya and 82 in Nigeria. Most (> 70%) of the CAPs treat both physical and mental illnesses. CAPs receive training through long years of apprenticeship. They use a combination of herbs, various forms of divination and rituals in the treatment of mental disorders. The use of physical restraints by CAPs to manage patients was relatively uncommon in Kenya (4%) compared to Nigeria (63.4%) and Ghana (21%). CAPs often have between 2- to 10-fold capacity for patient admission compared to conventional mental health facilities. The profile of CAPs in Kenya stands out from those of Ghana and Nigeria in many respects. CONCLUSION: CAPs are an important group of providers of mental health care in sub-Saharan Africa, but attempts to integrate them into the public health system must address the common use of harmful treatment practices.

Collaboration Between Biomedical and Complementary and Alternative Care Providers: Barriers and Pathways.

We examined the scope of collaborative care for persons with mental illness as implemented by traditional healers, faith healers, and biomedical care providers. We conducted semistructured focus group discussions in Ghana, Kenya, and Nigeria with traditional healers, faith healers, biomedical care providers, patients, and their caregivers. Transcribed data were thematically analyzed. A barrier to collaboration was distrust, influenced by factionalism, charlatanism, perceptions of superiority, limited roles, and responsibilities. Pathways to better collaboration were education, formal policy recognition and regulation, and acceptance of mutual responsibility. This study provides a novel cross-national insight into the perspectives of collaboration from four stakeholder groups. Collaboration was viewed as a means to reach their own goals, rooted in a deep sense of distrust and superiority. In the absence of openness, understanding, and respect for each other, efficient collaboration remains remote. The strongest foundation for mutual collaboration is a shared sense of responsibility for patient well-being.

Effectiveness of traditional healers in treating mental disorders: a systematic review.

Traditional healers form a major part of the mental health workforce worldwide. Despite this, little systematic examination has been done of their effectiveness in treating mental illness or alleviating psychological distress. In this Review, we aim to fill this gap, with a focus on quantitative outcomes. We searched four databases and reference lists for papers that explicitly measured the effectiveness of traditional healers on mental illness and psychological distress. Eligible papers were assessed for quality, and outcomes and other details were extracted with the use of a standardised template. 32 eligible papers from 20 countries were included. The published literature on this topic is heterogeneous and studies are generally of poor quality, although some findings emerge more consistently. Some evidence suggests that traditional healers can provide an effective psychosocial intervention. Their interventions might help to relieve distress and improve mild symptoms in common mental disorders such as depression and anxiety. However, little evidence exists to suggest that they change the course of severe mental illnesses such as bipolar and psychotic disorders. Nevertheless, qualitative changes that are captured poorly by conventional rating scales might be as important as the quantitative changes reviewed here. We conclude by outlining the challenges involved in assessing the effectiveness of traditional healers.

Voxel-Based Meta-Analytical Evidence of Structural Disconnectivity in Major Depression and Bipolar Disorder.

BACKGROUND: Identification of white matter microstructure differences and similarities between major depression and bipolar disorder is a necessary step to better understand the underlying brain abnormalities in affective disorders and target more effective treatments. However, research has not yet yielded robust conclusions. We report here a meta-analysis of diffusion tensor imaging studies in these conditions. METHODS: A comprehensive literature search was conducted up to 2014 to identify studies comparing fractional anisotropy (FA) between patients and control subjects. Results were combined to identify white matter abnormalities in major depression (736 patients vs. 668 control subjects) and bipolar disorder (536 patients vs. 489 control subjects). Effect size comparison and conjunction analysis allowed identification of similarities and differences between the disorders. RESULTS: A significant decrease in FA in the genu of the corpus callosum characterized both conditions. The comparison between unipolar and bipolar disorders revealed a greater decrease in FA in the left posterior cingulum in bipolar disorder. Studies that adopted tract-based spatial statistics methodology showed more pronounced reductions in these regions compared with voxel-based analyses. CONCLUSIONS: Major depression and bipolar disorder are characterized by abnormalities in white matter tracts of the genu of the corpus callosum that connect the two hemispheres of the prefrontal cortex implicated in mood regulation. Bipolar disorder was associated with reduced white matter integrity in the left posterior cingulum, which may contribute to cognitive impairment described in this condition. Tract-based spatial statistics may be a more sensitive technique to detect white matter abnormalities in these regions compared with voxel-based analyses.

The role of global traditional and complementary systems of medicine in the treatment of mental health disorders.

Traditional and complementary systems of medicine include a broad range of practices, which are commonly embedded in cultural milieus and reflect community beliefs, experiences, religion, and spirituality. Two major components of this system are discernible: complementary alternative medicine and traditional medicine, with different clientele and correlates of patronage. Evidence from around the world suggests that a traditional or complementary system of medicine is commonly used by a large number of people with mental illness. Practitioners of traditional medicine in low-income and middle-income countries fill a major gap in mental health service delivery. Although some overlap exists in the diagnostic approaches of traditional and complementary systems of medicine and conventional biomedicine, some major differences exist, largely in the understanding of the nature and cause of mental disorders. Treatments used by providers of traditional and complementary systems of medicine, especially traditional and faith healers in low-income and middle-income countries, might sometimes fail to meet widespread understandings of human rights and humane care. Nevertheless, collaborative engagement between traditional and complementary systems of medicine and conventional biomedicine might be possible in the care of people with mental illness. The best model to bring about that collaboration will need to be established by the needs of the extant mental health system in a country. Research is needed to provide an empirical basis for the feasibility of such collaboration, to clearly delineate its boundaries, and to test its effectiveness in bringing about improved patient outcomes.

The role of global traditional and complementary systems of medicine in treating mental health problems.

Traditional and complementary systems of medicine (TCM) encompass a broad range of practices which are commonly embedded within contextual cultural milieu, reflecting community beliefs, experiences, religion and spirituality. Evidence from across the world, especially from low- and middle-income countries (LMIC), suggests that TCM is commonly used by a large number of persons with mental illness. Even though some overlap exists between the diagnostic approaches of TCM and conventional biomedicine (CB), there are major differences, largely reflecting differences in the understanding of the nature and etiology of mental disorders. However, treatment modalities employed by providers of TCM may sometimes fail to meet common understandings of human rights and humane care. Still, there are possibilities for collaboration between TCM and CB in the care of persons with mental illness. Research is required to clearly delineate the boundaries of such collaboration and to test its effectiveness in bringing about improved patient outcomes.

Recruiting medical students into psychiatry in lower income countries.

There is a serious shortage of psychiatrists and poor recruitment of new psychiatry trainees worldwide. Low and middle income countries suffer disproportionately on many accounts. A negative attitude towards psychiatry is thought to contribute to poor recruitment of psychiatry trainees. Previous reviews have focused on the attitudes of medical students in high income countries, but factors relevant to attitude and recruitment may be different in lower income countries. Here we review studies of medical students' attitudes towards psychiatry from low and lower-middle income countries, summarize key themes which negatively influence attitudes, and suggest strategies for overcoming them. Major themes include stigma, perceived status of psychiatry, lack of psychiatric trainers, local cultural beliefs, poor working conditions, and quality of patient care.

Systematic review and voxel-based meta-analysis of diffusion tensor imaging studies in bipolar disorder.

BACKGROUND: Diffusion tensor imaging (DTI) studies have shown changes in the microstructure of white matter in bipolar disorder. Studies suggest both localised, predominantly fronto-limbic, as well as more widespread changes in white matter, but with some apparent inconsistency. A meta-analysis of white matter alterations in adults with bipolar disorder was undertaken. METHOD: Whole-brain DTI studies comparing adults with bipolar disorder to healthy controls on fractional anisotropy (FA) were retrieved using searches of MEDLINE and EMBASE from between 2003 and December 2012. White-matter tract involvement was collated and quantified. Clusters of significantly altered FA were meta-analysed using effect-size signed differential mapping (ES-SDM). RESULTS: Ten VBA studies (252 patients and 256 controls) and five TBSS studies (138 patients and 98 controls) met inclusion criteria. Sixty-one clusters of significantly different FA between bipolar disorder and healthy controls were identified. Analysis of white-matter tracts indicated that all major classes of tracts are implicated. ES-SDM meta-analysis of VBA studies revealed three significant clusters of decreased FA in bipolar disorder (a right posterior temporoparietal cluster and two left cingulate clusters). Findings limited to the Bipolar Type I papers were more robust. LIMITATIONS: Voxel-based studies do not accurately identify tracts, and our ES-SDM analysis used only published peak voxels rather than raw DTI data. CONCLUSIONS: There is consistent data indicating widespread white matter involvement with decreased white matter FA demonstrated in three disparate areas in bipolar disorder. White matter alterations are not limited to anterior fronto-limbic pathways in bipolar disorder.
