Background: Substance use disorders (SUDs) occur frequently in patients with psychotic disorders and have been associated with various demographic and clinical correlates. There is an absence of research on the prevalence and clinical correlates of SUDs in psychotic disorders in low-and-middle-income countries (LMICs). Aim: We aimed to determine the prevalence and correlates of SUDs in psychotic disorders. Setting: Patients attending a large secondary-level psychiatric hospital in Cape Town South Africa. Methods: We used the Structured Clinical Interview for DSM-IV (SCID-I) to determine psychiatric and substance use diagnoses, depressive, anxiety, obsessive-compulsive and post-traumatic symptoms. We used logistic regression models to determine significant predictors of SUDs. Results: In total sample ( N = 248), 55.6% of participants had any SUD, 34.3% had cannabis use disorders, 30.6% alcohol use disorders, 27.4% methamphetamine use disorders, 10.4% methaqualone use disorders and 4.8% had other SUDs. There were significant associations with male sex for most SUDs, with younger age and Coloured ethnicity for methamphetamine use disorders, and with lower educational attainment for cannabis use disorders. Anxiety symptoms and suicide attempts were significantly associated with alcohol use disorders; a diagnosis of a substance induced psychosis with cannabis and methamphetamine use disorders. Across most SUDs legal problems and criminal involvement were significantly increased. Conclusion: This study found a high prevalence and wide distribution of SUDs in patients with psychotic disorders, consistent with previous work from high income countries. Given clinical correlates, in individuals with psychotic disorders and SUDs it is important to assess anxiety symptoms, suicidality and criminal involvement.

Objective Large-scale studies have revolutionized biomedical research, and neurocognitive tests can help elucidate the biological basis of neuropsychiatric diseases. However, studies have predominantly been conducted in Western settings. We describe the development and validation of a computerized battery (PennCNB) with the Xhosa population of South Africa. Method Individuals with schizophrenia (n = 525) and a normative comparison group (n = 744) were balanced on age, sex, education, and region. Participants provided blood samples, were assessed psychiatrically, and were administered a PennCNB translation to isiXhosa, including measures of executive functions, episodic memory, complex cognition, social cognition, and sensorimotor speed. Feasibility was examined with test completion rates and input from administrators, and psychometric structural validity and associations with clinical and demographic characteristics were examined. Results Tests were well tolerated by participants, as >87% had one (or fewer) test missing. Results suggested a similar factor structure to prior PennCNB studies in Western contexts, and expected age and sex effects were apparent. Furthermore, a similar profile of schizophrenia was observed, with neurocognitive deficits most pronounced for executive functions, especially attention, as well as memory, social cognition, and motor speed relative to complex cognition and sensorimotor speed. Conclusions Results support the feasibility of implementing a culturally adapted computerized neurocognitive battery in sub-Saharan African settings and provide evidence supporting the concurrent validity of the translated instrument. Thus, the PennCNB is implementable on a large scale in non-Western contexts, shows expected factor structure, and can detect cognitive deficits associated with neuropsychiatric disorders. Obtaining valid measures of cognition by nonspecialized proctors is especially suitable in resource-limited settings, where traditional testing is prohibitive. Future work should establish normative standards, test-retest reliability, and sensitivity to treatment. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

Mental health and neurocognitive functioning remain a concern among people living with HIV. Symptomatic neurocognitive impairment (NCI) and mental illness can cause difficulties in daily functioning, including problems adhering to treatment. However, many healthcare workers in resource-limited settings have limited knowledge about the relationship between HIV and NCI. A synthesis of available literature on mental health and NCI training provided to healthcare workers delivering HIV services in Africa, is lacking. We conducted a scoping review of published literature to identify training interventions which targeted healthcare workers providing careto people with HIV in Africa. Ten studies met the inclusion criteria. One study focused on NCI, two studies mentioned HIV-associated dementia and seven studies were centred on common mental health disorders. Most studies used a multi-method training approach, with pre-and post-testing as the main evaluation technique. This review highlights the gap in training interventions addressing NCI in Africa. Although there is some commitment to building capacity for mental health and NCI assessment among healthcare workers in this setting, this review suggests that there is a need for research to develop and evaluate training interventions for healthcare workers delivering HIV services in Africa.

To determine the prevalence of substance use disorders (SUDs) in patients with schizophrenia in a sample from South Africa and compare the clinical and demographic correlates in those with and without co-occurring SUDs. Patients with schizophrenia were interviewed using the Xhosa version SCID-I for DSM-IV. We used logistic regression to determine the predictors of SUDs. In the total sample of 1420 participants, SUDs occurred in 47.8%, with the most prevalent SUD being cannabis use disorders (39.6%), followed by alcohol (20.5%), methaqualone (6.2%), methamphetamine (4.8%) and other SUDs (cocaine, ecstasy, opioids, 0.6%). Polydrug use occurred in 40%, abuse occurred in 13.5%, and 39.6% had at least one substance dependence diagnosis. Significant predictors of any SUD were younger age (41–55 vs. 21–30: OR = 0.7, 95% CI = 0.5–0.9), male sex (OR = 8.6, 95% CI = 5.1–14.6), inpatient status (OR = 1.7, 95% CI = 1.3–2.1), post-traumatic stress symptoms (OR = 4.6, 95% CI = 1.6–13.3), legal (OR = 3.4, 95% CI = 2.0–5.5) and economic problems (OR = 1.4, 95% CI = 1.0–2.0). Methamphetamine use disorders occurred significantly less often in the Eastern compared to the Western Cape provinces. Inpatient status and higher levels of prior admissions were significantly associated with cannabis and methamphetamine use disorders. Post-traumatic stress symptoms were significantly associated with alcohol use disorders. Anxiety disorders were associated with other SUDs. SUDs occurred in almost half of the sample. It is important for clinicians to identify the presence of SUDs as their presence is associated with characteristics, such as male sex, younger age, inpatient status, more prior hospitalisations, legal and economic problems, PTSD symptoms and anxiety.

The South Africa HIV Addiction Technology Transfer Center (ATTC) was formed in 2017 to train health professionals and nonprofessional lay workers in evidence-based addiction interventions as a strategy for addressing the country’s HIV epidemic. This article describes the Year 1 activities of the South Africa HIV ATTC including an initial needs assessment with high-level stakeholders, an advisory board meeting with South African government and nongovernment agencies, a learning exchange with other international ATTCs, and the identification of Screening, Brief Intervention, and Referral to Treatment (SBIRT) as a focal intervention for widespread training. The article details the culmination of Year 1 activities via a national forum on SBIRT and presents posttraining satisfaction data across SBIRT events. Lessons learned during the first year include the importance of building strong partnerships with high-level stakeholders, conducting a targeted needs assessment, and identifying a focal intervention for widespread dissemination. Trainees reported high satisfaction and intention to use the knowledge and skills gained. Overall, the methods used by the South Africa HIV ATTC demonstrate a novel approach to training health professionals and lay health workers in evidence-based addiction services as a means of improving HIV outcomes.

Reliable, clinically useful, and globally applicable diagnostic classification of mental disorders is an essential foundation for global mental health. The World Health Organization (WHO) is nearing completion of the 11th revision of the International Classification of Diseases and Related Health Problems (ICD‐11). The present study assessed inter‐diagnostician reliability of mental disorders accounting for the greatest proportion of global disease burden and the highest levels of service utilization – schizophrenia and other primary psychotic disorders, mood disorders, anxiety and fear‐related disorders, and disorders specifically associated with stress – among adult patients presenting for treatment at 28 participating centers in 13 countries. A concurrent joint‐rater design was used, focusing specifically on whether two clinicians, relying on the same clinical information, agreed on the diagnosis when separately applying the ICD‐11 diagnostic guidelines. A total of 1,806 patients were assessed by 339 clinicians in the local language. Intraclass kappa coefficients for diagnoses weighted by site and study prevalence ranged from 0.45 (dysthymic disorder) to 0.88 (social anxiety disorder) and would be considered moderate to almost perfect for all diagnoses. Overall, the reliability of the ICD‐11 diagnostic guidelines was superior to that previously reported for equivalent ICD‐10 guidelines. These data provide support for the suitability of the ICD‐11 diagnostic guidelines for implementation at a global level. The findings will inform further revision of the ICD‐11 diagnostic guidelines prior to their publication and the development of programs to support professional training and implementation of the ICD‐11 by WHO member states.

Objectives Medication non-adherence is a significant problem in treatment of severe mental disorders and is associated with poor clinical outcomes and increased demand on services. Task-shifting interventions incorporating mobile health may improve adherence in mental health service users in low- and middle-income countries. Seventy-seven participants were recruited from a psychiatric hospital in Cape Town, with 42 randomized to receive the intervention and 35 to treatment as usual. Intervention pairs underwent treatment-partner contracting and psychoeducation, and received monthly text message reminders of clinic appointments. Primary outcomes were intervention acceptability and feasibility. Secondary outcome for efficacy were adherence to clinic visit; relapse; quality of life; symptomatic relief and medication adherence. Results Treatment partner and psychoeducation components were acceptable and feasible. The text message component was acceptable but not feasible in its current form. Efficacy outcomes favoured the intervention but did not reach statistical significance. A treatment-partner intervention is acceptable and feasible in a low- and middle-income setting. Work is needed to ensure that additional components of such interventions are tailored to the local context. Appropriately powered efficacy studies are needed.

Objective: Extrapyramidal side-effects (EPSE) are frequent in patients treated with antipsychotics and comorbid substance use disorders (SUDs). Methamphetamine has been shown to act as a dopaminergic neurotoxin. We aimed to determine whether EPSE occur more often in patients with psychotic disorders and co-occurring methamphetamine (MA) use disorders, and we examined the relationship between MA use, antipsychotic type, dose and EPSE. Methods: This study was a secondary analysis of data from three separate primary studies. Across all studies, psychiatric and SUD diagnoses were determined using the SCID-I for DSM-IV. EPSE were determined using the Simpson-Angus Scale (SAS) for Parkinsonism, the Barnes Akathisia Rating scale (BARS), and the Abnormal Involuntary Movement Scale (AIMS) for tardive dyskinesia. Participants were classified as having any EPSE if they scored above the cutoff on any of the EPSE scales (SAS, BARS, AIMS). We analyzed data using multivariable logistic regression analysis. Results: The sample included 102 patients with non-affective or affective psychotic disorders. Of the total sample, 65.7% were male, 54.9% had schizophrenia spectrum disorders, 20.5% bipolar type I disorder with psychotic features, 11.7% schizoaffective disorder and 12.7% had substance-induced psychosis. A diagnosis of a methamphetamine use disorder (abuse or dependence) was present in 25.5% of participants. EPSE occurred in 38.2% of patients and were significantly associated with MA use in the unadjusted and adjusted analysis, ORadj = 4.01, 95% CI [1.07, 14.98], p =.039. Patients with MA dependence and MA use >3 years were significantly more likely to have EPSE. We found a significant interaction effect between MA use disorders and standardized antipsychotic dose on the occurrence of EPSE, ORadj = 1.01, 95% CI [1.00, 1.01], p =.042, with MA users having a disproportionally higher likelihood of having EPSE compared to MA non-users as antipsychotic dosage increased. There were no significant associations of EPSE with comorbid alcohol, cannabis, or methaqualone use disorders. Conclusions: Patients with a MA use disorder were significantly more likely to have EPSE with evidence for a dose-response effect. Clinicians should carefully titrate antipsychotic dosage from lower to higher doses to avoid EPSE in patients with MA use disorders.

African schizophrenia genetic variants The genetics of schizophrenia have predominately been studied in populations of European and Asian descent. However, studies in Africans, who host the greatest degree of human genetic diversity, have lagged. Examining the exomes of more than 1800 Xhosa individuals from South Africa, about half of which have been diagnosed with schizophrenia, Gulsuner et al. identified both rare and common genetic variants associated with the disease. They found that the genetic architecture of schizophrenia in Africans generally reflects that of Europeans but that the greater genetic variation in Africa provides more power to detect relationships of genes to phenotypes.

IntroductionSchizophrenia and bipolar disorder account for a large proportion of the global burden of disease. Despite their enormous impact, little is known about their pathophysiology. Given the high heritability of schizophrenia and bipolar disorder, unbiased genetic studies offer the opportunity to gain insight into their neurobiology. However, advances in understanding the genetic architecture of schizophrenia and bipolar disorder have been based almost exclusively on subjects of Northern European ancestry. The Neuropsychiatric Genetics of African Populations-Psychosis (NeuroGAP-Psychosis) project aims to expand our understanding of the causes of schizophrenia and bipolar disorder through large-scale sample collection and analyses in understudied African populations.Methods and analysisNeuroGAP-Psychosis is a case-control study of 34 000 participants recruited across multiple sites within Ethiopia, Kenya, South Africa and Uganda. Participants will include individuals who are at least 18 years old with a clinical diagnosis of schizophrenia or bipolar disorder (‘psychosis’) or those with no history of psychosis. Research assistants will collect phenotype data and saliva for DNA extraction. Data on mental disorders, history of physical health problems, substance use and history of past traumatic events will be collected from all participants.DNA extraction will take place in-country, with genotyping performed at the Broad Institute. The primary analyses will include identifying major groups of participants with similar ancestry using the computation-efficient programme single nucleotide polymorphisms (SNP) weights. This will be followed by a GWAS within and across ancestry groups.Ethics and disseminationAll participants will be assessed for capacity to consent using the University of California, San Diego Brief Assessment of Capacity to Consent. Those demonstrating capacity to consent will be required to provide informed consent. Ethical clearances to conduct this study have been obtained from all participating sites. Findings from this study will be disseminated in publications and shared with controlled access public databases, such as the database of Genotypes and Phenotypes, dbGaP.

Background There is a shortage of trained mental health workers in spite of the significant contribution of psychiatric disorders to the global disease burden. Task shifting, through the delegation of health care tasks to less specialised health workers such as community health workers (CHWs), is a promising approach to address the human resource shortage. CHWs in the Western Cape province of South Africa provide comprehensive chronic support which includes that for mental illness, but have thus far not received standardized mental health training. It is unknown whether a structured mental health training programme would be acceptable and feasible, and result improved knowledge, confidence and attitudes amongst CHWs. Methods We developed and piloted a mental health training programme for CHWs, in line with the UNESCO guidelines; the WHO Mental Health Gap Action Programme and the South African National framework for CHW training. In our quasi-experimental (before-after) cohort intervention study we measured outcomes at the start and end of training included: 1) Mental health knowledge, measured through the use of case vignettes and the Mental Health Knowledge Schedule; 2) confidence, measured with the Mental Health Nurse Clinical Confidence Scale; and 3) attitudes, measured with the Community Attitudes towards the Mentally Ill Scale. Knowledge measures were repeated 3 months later. Acceptability data were obtained from daily evaluation questionnaires and a training evaluation questionnaire, while feasibility was measured by participant attendance at training sessions. Results Fifty-eight CHWs received the training, with most (n = 56, 97.0%) attending at least 7 of the 8 sessions. Most participants (n = 29, 63.04%) demonstrated significant improvement in knowledge, which was sustained at 3-months. There was significant improvement in confidence, along with changes in attitude, indicating improved benevolence, reduced social restrictiveness, and increased tolerance to rehabilitation of the mentally ill in the community but there was no change in authoritarian attitudes. The training was acceptable and feasible. Conclusions Mental health training was successful in improving knowledge, confidence and attitudes amongst trained CHWs. The training was acceptable and feasible. Further controlled studies are required to evaluate the impact of such training on patient health outcomes.

Background: Methamphetamine psychosis (MAP) symptomatology has been described as indistinguishable from that of schizophrenia (SZ), yet research comparing these two disorders on specific psychotic symptoms such as schneiderian first-rank symptoms (FRS) is lacking. We aimed to determine and compare the occurrence and associations of FRS in patients diagnosed with MAP and with SZ. Sampling and Method: Data from SCID-I interviews performed on patients with either a diagnosis of SZ or MAP were compared. We calculated the prevalence of different FRS between MAP and SZ patients and used logistic regression to assess the association between FRS and diagnosis. Results: 102 patients were included in the study (MAP = 33, SZ = 69). Thought broadcasting occurred significantly more often in SZ (42%) than in MAP (24.2%) patients (adjusted OR = 3.02; 95% CI: 1.12-8.15; p = 0.028), while auditory hallucinations (voices conversing) were significantly higher in MAP (48.5%) than in SZ (20.3%) patients (adjusted OR = 0.27; 95% CI: 0.10-0.66; p = 0.004). However, there was no significant difference in the occurrence of one or more FRS in MAP and SZ, with most FRS showing overlap. Conclusions: We found that first-rank auditory hallucinations were more prevalent in MAP, whereas first-rank delusions of thought broadcasting were more prevalent in SZ. However, there was a substantial overlap in MAP and SZ for most FRS. This is consistent with the finding that FRS may have limited diagnostic specificity and that there is significant overlap in the symptoms of MAP and SZ. Future research into the neurobiology of delusions and hallucinations needs to take FRS into account.

Background: Although the relationship between cultural beliefs and schizophrenia has received some attention, relatively little work has emerged from African contexts. In this study we draw from a sample of South African Xhosa people with schizophrenia, exploring their cultural beliefs and explanations of illness. The purpose of the article is to examine the relationship between this cultural context and the content of delusions. Methods: A sample comprising 200 Xhosa people with schizophrenia participating in a South African schizophrenia genomics study were interviewed using the Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I). Participant delusions were thematically analyzed for recurring themes. Results: The majority of participants (n = 125 72.5%) believed that others had bewitched them in order to bring about their mental illness, because they were in some way jealous of the participant. This explanation aligns well with the understanding of jealousy-induced witchcraft in Southern African communities and highlights the important role that culture plays in their content of delusions. Conclusions: Improved knowledge of these explanatory frameworks highlights the potential value of culturally sensitive assessment tools and stigma interventions in patient recovery. Furthermore such qualitative analyses contribute towards discussion about aspects of delusional thought that may be more universally stable, and those that may be more culturally variable.

Background: Our study explores perceptions of the caregiver support for mental health service users (MHSUs) in a low- to middle-income country setting. Materials: We conducted in-depth individual interviews with 16 MHSUs and their treatment partners/caregivers from a treatment partner and text-message intervention study. Discussion: Treatment partners/caregivers felt obligated to care for MHSUs, but had a limited understanding of mental illness. They found supporting adherence to treatment difficult due to a number of factors including violence, food insecurity and substance abuse. Conclusion: Socioeconomic and environmental factors affecting the lives of MHSUs have impact on caregiver relationships with MHSUs in their care.

Background Community engagement within biomedical research is broadly defined as a collaborative relationship between a research team and a group of individuals targeted for research. A Community Advisory Board (CAB) is one mechanism of engaging the community. Within genomics research CABs may be particularly relevant due to the potential implications of research findings drawn from individual participants on the larger communities they represent. Within such research, CABs seek to meet instrumental goals such as protecting research participants and their community from research-related risks, as well as intrinsic goals such as promoting the respect of participants and their community. However, successful community engagement depends on the degree to which CABs legitimately represent and engage with communities targeted for research. Currently, there is little literature describing the use of CABs in genomics research taking place in developing countries, and even less in the field of genomics research relating to mental illness. The aim of this article is to describe and consider the contributions made by a researcher-driven, population-specific CAB in a genomics of schizophrenia research project taking place in South Africa, from the perspective of the research team. Discussion Four broad discussion topics emerged during the CAB meetings namely: 1) informed consent procedures, 2) recruitment strategies, 3) patient illness beliefs and stigma experiences, and 4) specific ethical concerns relating to the project. The authors consider these discussions in terms of their contributions to instrumental and intrinsic goals of community engagement. Summary The CAB gave valuable input on the consent processes and materials, recruitment strategies and suggested ways of minimizing the potential for stigma and discrimination. All of these contributions were of an instrumental nature, and helped improve the way in which the research took place. In addition, and perhaps more importantly, the CAB made a unique and important contribution relating to intrinsic functions such as promoting the respect and dignity of research participants and their community. This was particularly evident in ensuring sensitivity and respect of the community’s traditional beliefs about schizophrenia and its treatment, and in this way promoting a respectful relationship between the research team and the participants.

Objective : Poor adherence to medications, including psychotropic medications contributes to the burden of disease. Mental health service users (MHSU) may also not attend follow-up appointments at their health care facilities where they could discuss adherence with their health care provider. This paper reports on preliminary qualitative research preceding a randomised controlled trial that aims to improve adherence to psychotropic medication and to follow up treatment visits. The intervention will entail the support of individuals with serious mental disorder by a treatment partner and short message service (SMS) text messaging. Methods : The preliminary research reported in this paper aimed to extract views about the intervention from both mental health service users (MHSU) and caregivers through focus group discussions and individual interviews. Data were analysed using ATLAS TI qualitative software. Results : The caregivers interviewed were all mothers of MHSU who took measures to encourage adherence. They held mixed opinions on whether the treatment partner should be a family member. Most participants expressed the view that due to living conditions, family members were natural treatment partners, but others stated that they would prefer a treatment partner who was not a family member. Similarly, while most MHSU supported the idea of a treatment partner, a minority were concerned that a treatment partner may potentially be too controlling and compromise their autonomy. The vast majority of participants supported SMS text messaging as a means of reminding MHSU to take their medication and attend followup appointments. One participant mentioned the importance of broader social inclusion issues that should be incorporated in the intervention. Conclusion : Qualitative research may provide useful insights for the design of interventions of this nature related to social inclusion randomised control trials with its focus on adherence.

In recent years there have been significant insights into the complex aetiologies of neurodevelopmental brain disorders. For example, neuropsychiatric genetics has achieved success with the identification of 108 loci for schizophrenia (Schizophrenia Working Group of the Psychiatric Genomics Consortium, 2014). Furthermore, meta-analyses of genome-wide association study (GWAS) results encompassing thousands of samples have been completed for other psychiatric disorders including attention-deficit/hyperactivity disorder (ADHD), autism spectrum disorders, bipolar disorder, and major depressive disorder. However, published results on neuropsychiatric disorders have – thus far – predominantly included samples of European ancestry. In Fig. 1a, we compare world ancestry to the ancestry of individuals in the largest psychiatric GWAS meta-analyses published prior to 2015 (Total N = 121,985). The lack of African samples in the meta-analyses so clearly depicted here, raises concern that Africa will be left behind in terms of neuropsychiatric genetic research and subsequent treatment innovation. Fig. 1 Proportion of world population groups in psychiatric GWAS. (a) Proportion investigated in the largest meta-analyses published prior to 2015 for four leading psychiatric disorders (schizophrenia (Schizophrenia Working Group of the Psychiatric Genomics ... There is biological rationale for conducting genetic research in African populations. It has been shown that modern humans originated in Africa and subsequently migrated to other parts of the world (Campbell and Tishkoff, 2008). As the cradle of humanity, Africa and its indigenous populations are a valuable resource when it comes to genetic research. Modern African genomes are characterised by a unique pattern of variation as a result of migration and admixture in earlier generations as well as recombination, natural selection and mutation. With an increase in allelic diversity and shorter segments of linkage disequilibrium, African genomes hold informative alleles which are useful for fine mapping of disease causing alleles (Campbell and Tishkoff, 2008). However, there is limited knowledge on African-specific functional variants highlighting the need to investigate African population groups, particularly for neuropsychiatric disorders. As genetic findings are translated into intervention, genetic research focused solely on European populations threatens to widen the existing large disparity between Africa and the rest of the world in mental health treatment. The vast majority of work is being conducted in high-income settings, such as the U.S.A. and Denmark, with a large proportion of subjects of Northern European ancestry (Fig. 1a). To date, there have been no large-scale studies on the genetics of neuropsychiatric disorders in African populations. The few studies that have been conducted have been on small samples, typically under a thousand in number (Kolassa et al., 2010). Recent successes in studies of schizophrenia have demonstrated that very large scale meta-analysis is necessary to identify genetic variants associated with neuropsychiatric disorders. Without engaging African scientists and physicians and performing studies of African populations, there is a significant risk that the recent advances in neuropsychiatric genetics will result in a widening of the massive research and treatment gaps between Africa and the rest of the world. Indeed, one of the aims of the movement for global mental health is to decrease inequality in mental health outcomes particularly for low- and middle-income countries (Patel, 2012), typical of much of the African continent. Researchers in Africa are faced with a number of unique challenges. Research funding is scarce, and African scientists are often not eligible for training mechanisms offered by the National Institutes of Health and other funding agencies. Much of the funding that is available focuses on public mental health issues rather than on neuroscience or the integration of neuroscience with public mental health (Stein et al., 2015). Also, many African countries lack the infrastructure required to conduct large-scale neuropsychiatric genetics research, e.g. refrigeration for blood samples and cloud-based technology for phenotypic data collection. Furthermore, there is a shortage of highly skilled geneticists and clinician-scientists, highlighting the need for training and capacity building in African countries. In particular, clinicians need to develop culturally appropriate tools for the diagnosis and phenotyping of these disorders. There are also several ethical considerations, especially in the context of collaborative global health partnerships between high and low to middle income countries. These include ethical issues about informed consent; poverty, low literacy, language barriers and poor access to healthcare (De Vries et al., 2011). Additionally, fairness in international collaboration needs to be ensured, with researchers having equal access to data, and intellectual property rights adequately addressed. When working with individuals with mental health problems, in countries with a lack or paucity of mental health prioritization, these types of challenges are exacerbated. Lastly, existing microarray panels may not adequately capture common haplotypes in African populations. This highlights the need for genotyping chips which contain tag single nucleotide polymorphisms (SNPs) that are able to encapsulate common variation across African population groups (Gurdasani et al., 2015). Despite these challenges, a number of emerging studies may hold promise for future neurogenetics research in Africa. For example, the Drakenstein Child Health Study (http://www.paediatrics.uct.ac.za/scah/dclhs) is a multidisciplinary South African birth cohort study investigating genetic and environmental risk factors for common mental disorders. The cohort consists of 1200 mother–child pairs and a subset of these individuals has already been genotyped with a genome-wide panel of markers shown to be relevant to psychiatric disorders. The post-traumatic stress disorder (PTSD) subgroup of the multi-national Psychiatric Genomics Consortium (PGC) (http://www.med.unc.edu/pgc) aims to carry out large-scale GWASs and has included South African samples in their analyses. To date, the PTSD-PGC group has access to approximately 20,000 samples from study sites. As depicted by Fig. 1b, the ancestry of individuals in the PGC-PTSD studies is more diverse than large psychiatric GWAS in general. The Enhancing Neuro Imaging Genetics through Meta-Analysis (ENIGMA) Network (http://enigma.ini.usc.edu/about-2/), a consortium investigating brain structure, function and disease using brain imaging and genomics, has also included samples from South Africa. This consortium comprises 70 institutions world-wide and consists of different disease working groups including those for schizophrenia, bipolar disorder and PTSD, respectively. Lastly, the Human Heredity and Health in Africa (H3Africa) (http://h3africa.org/) initiative seeks to improve health in African populations by investigating genomic and environmental factors contributing to common disease. This initiative includes a study investigating the genetic basis of schizophrenia in the southern African Xhosa-speaking population group. Using exome-sequencing and by investigating genome-wide copy-number variation, this study aims to identify genes associated with schizophrenia. Similarly, an initiative tentatively called the Neuropsychiatric Genetics in African Populations (Neuro-GAP), by the Stanley Center for Psychiatric Research of the Broad Institute of MIT and Harvard University, in collaboration with the University of Cape Town and a number of other African institutions, aims to improve and achieve equity in mental health by expanding the infrastructure and research findings from large-scale psychiatric genetic epidemiology to Africa. This will be achieved by enhancing neuropsychiatric genetic research capacity in Africa through the training of scientists, conducting very large-scale sample collection and analysis through supporting the development of locally led research programmes in neuropsychiatric genetics and leveraging unique opportunities in population genetics. In conclusion, while there is a clear need for further work in elucidating the genetics of neuropsychiatric disorders in African populations, several challenges will first need to be tackled. An effective local network of neurogenetic researchers needs to be established in order to discover genetic variation predisposing to neuropsychiatric disorders. This research needs to avoid prior pitfalls of “safari research” by engaging and training African scientists and physicians to improve phenotyping and perform studies of African populations to ensure long-term capacity to translate genetic findings in a way that will benefit African peoples.
