Urban life shapes the mental health of city dwellers, and although cities provide access to health, education and economic gain, urban environments are often detrimental to mental health1,2. Increasing urbanization over the next three decades will be accompanied by a growing population of children and adolescents living in cities3. Shaping the aspects of urban life that influence youth mental health could have an enormous impact on adolescent well-being and adult trajectories4. We invited a multidisciplinary, global group of researchers, practitioners, advocates and young people to complete sequential surveys to identify and prioritize the characteristics of a mental health-friendly city for …

Addition Of Mental Health To The Lady Health Worker Curriculum In Pakistan: Now Or Never, Fauziah Rabbani, Samina Akhtar, Javeria Nafis, Shahid Khan, Sameen Siddiqi, Zul Merali

Brain and Mind Institute

The technical advisory group of the World Health Organization (Geneva, Switzerland) has suggested person-centered and community-based mental health services in response to the long-term and far-reaching mental health impacts of the COVID-19 pandemic. Task shifting is a pragmatic approach to tackle the mental health treatment gap in low- and middle-income countries. Pakistan is dismally resourced to address the mental health challenges. Pakistan’s government has established a lady health worker’s program (LHW-P) which can be effectively utilized to provide some basic mental health services at community doorsteps. However, lady health workers’ current curriculum does not include mental health as a subject. …

Flourishing With Chronic Illness(Es) And Everyday Stress: Experiences From Soweto, South Africa, Megan Schmidt-Sane, Lindile Cele, Edna Bosire, Alexander C. Tsai, Emily Mendenhall

Brain and Mind Institute

The pursuit of flourishing, or living a good life, is a common human endeavor with different meanings across individuals and contexts. What is needed is a further exploration of the relationship between flourishing and health, particularly chronic illness, which affects individuals across the life course and is affected by experiences of stress derived from social and structural vulnerability.

Drawing on data from the Soweto Syndemics study, including a locally derived stress scale and in-depth interviews, we explore the connections between flourishing and health for those living with multiple chronic illnesses in Soweto, South Africa within a syndemic of communicable and …

Brain and Mind Institute

Introduction: There is paucity of culturally adapted tools for assessing depression and anxiety in children and adolescents in low-and middle-income countries. This hinders early detection, provision of appropriate and culturally acceptable interventions. In a partnership with the University of Nairobi, Nairobi County, Kenyatta National Hospital, and UNICEF, a rapid cultural adaptation of three adolescent mental health scales was done, i.e., Revised Children’s Anxiety and Depression Scale, Patient Health Questionnaire-9 and additional scales in the UNICEF mental health module for adolescents.

Materials and methods: Using a qualitative approach, we explored adolescent participants’ views on cultural acceptability, comprehensibility, relevance, and completeness of …

Patterns Of Suicide And Self-Harm In Pakistan: A Retrospective Descriptive Study Protocol, Nargis Asad, Summaiya Tariq, Asra Qureshi, Mohammad Zaman, Mustafa Aslam, Farhat Mirza, Murad Khan

Brain and Mind Institute

Introduction Suicide is a major global public health problem. Low-income and middle-income countries contribute 78% of all suicidal deaths. Pakistan, a South Asian country, lacks official statistics on suicides at national level. Statistics on suicide are neither collected nationally nor published in the annual national morbidity and mortality surveys. Medicolegal reports on suicides and self-harm are extremely rich and important source of information but greatly underused in Pakistan. We aim to examine the patterns of suicides and self-harm retrospectively in patients who were registered with medicolegal centres (MLCs) in Karachi, during the period January 2017 to December 2021.

Brain and Mind Institute

African populations are the most diverse in the world yet are sorely underrepresented in medical genetics research. Here, we examine the structure of African populations using genetic and comprehensive multi-generational ethnolinguistic data from the Neuropsychiatric Genetics of African Populations-Psychosis study (NeuroGAP-Psychosis) consisting of 900 individuals from Ethiopia, Kenya, South Africa, and Uganda. We find that self-reported language classifications meaningfully tag underlying genetic variation that would be missed with consideration of geography alone, highlighting the importance of culture in shaping genetic diversity. Leveraging our uniquely rich multi-generational ethnolinguistic metadata, we track language transmission through the pedigree, observing the disappearance of several …

A Call For Prudent Taxation Of Cannabis Corporates To Fund Mental Health Programmes, Cyprian Mostert, Jasmit Shah, Lukoye Atwoli, Zul Merali, Manasi Kumar Sep 2022

A Call For Prudent Taxation Of Cannabis Corporates To Fund Mental Health Programmes, Cyprian Mostert, Jasmit Shah, Lukoye Atwoli, Zul Merali, Manasi Kumar

Brain and Mind Institute

Cannabis consumption increases the incidence of psychotic disorders, violence, and cognitive impairments [1]. Governments need to implement progressive tax legislation, such as that which requires the cannabis sector to accept responsibility and account for its contribution to the worsening of these mental health conditions in developing countries. Excise taxes are rarely imposed on the cannabis sector [2], despite the lucrative wealth amassed by this industry. For example, current estimates show that the global cannabis sector was valued at $25 billion in 2021 and is projected to reach $176 billion by 2030, driven solely by cannabis inhalation demands [3]. The projected …

Association Between Suicide Rate And Human Development Index, Income, And The Political System In 46 Muslim-Majority Countries: An Ecological Study, S. M. Yasir Arafat, Marthoenis Marthoenis, Murad Khan, Mohsen Rezaeian

Brain and Mind Institute

Very little has been researched assessing the relationship between the suicide rate and the ecological perspectives of the country, especially in the Muslim majority countries. We aimed to determine the association between suicide rate and the ecological parameters of 46 Muslim majority countries. We extracted the Muslim majority countries and their suicide rate, income distribution, distribution of the WHO region and continents, and Human Development Index (HDI). We assessed the correlation of the proportion of Muslim populations, the total population of the countries, number of suicides, continent, income group, political system, and HDI score with the suicide rate. The median …


Mental Health And Climate Change In Africa, Lukoye Atwoli, Joy Muhia, Zul Merali Jun 2022

Mental Health And Climate Change In Africa, Lukoye Atwoli, Joy Muhia, Zul Merali

Brain and Mind Institute

It is now widely acknowledged that low- and middle-income countries in Africa are among global hotspots for high vulnerability to climate change, despite making comparatively low contributions to this phenomenon. Climate change has been shown to affect mental health as a result of disruption of social and economic structures that populations depend on for good health, including mental health. After decades of neglect, recent efforts by governments such as in Kenya to address the twin issues of climate change and mental health demonstrate the growing importance of these issues. Here we briefly review the evidence of climate change impacts on …

Choo, Brenda Wandika, Jenna L. Udren, Lusi Osborn, Peninah Kithao, Anna B. Hedstrom, Millicent Masinde, Manasi Kumar, Dalton C. Wamalwa

Brain and Mind Institute

Abstract: Introduction Globally, approximately half of the estimated 6.3 million under-5 deaths occur in the neonatal period (within the first 28 days of life). Kenya ranks among countries with the highest number of neonatal deaths, at 20 per 1000 live births. Improved identification and management of neonates with potentially life-threatening illness is critical to meet the WHO’s target of ≤12 neonatal deaths per 1000 live births by 2035. We developed an interactive (two-way) short messaging service (SMS) communication intervention, Mobile Solutions for Neonatal Health (Mobile women’s and children’s health (WACh) NEO), focused on the perinatal period. Mobile WACh NEO sends …

Extract And Active Principal Of The Neotropical Vine Souroubea Sympetala Gilg. Block Fear Memory Reconsolidation, Anthony Murkar, Hristian Cayer, Jon James, Tony Durst, John T. Arnason, Pablos E. Sanchez-Vindas, M. Otarola Rojas, Zul Merali

Brain and Mind Institute

Background: Souroubea sympetala Gilg. is a neotropical vine native to Central America, investigated as part of a targeted study of the plant family Marcgraviaceae. Our previous research showed that extract of S. sympetala leaf and small branch extract had anxiolytic effects in animals and acts as an agonist for the GABAA receptor at the benzodiazepine binding site. To date, the potential effects of S. sympetala and its constituents on reconsolidation have not been assessed. Reconsolidation, the process by which formed memories are rendered labile and susceptible to change, may offer a window of opportunity for pharmacological manipulation of learned fear. …


Cannabidiol And The Remainder Of The Plant Extract Modulate The Effects Of Δ9-Tetrahydrocannabinol On Fear Memory Reconsolidation, Anthony Murkar, Pam Kent, Christian Cayer, Jon James, Tony Durst, Zul Merali Aug 2019

Cannabidiol And The Remainder Of The Plant Extract Modulate The Effects Of Δ9-Tetrahydrocannabinol On Fear Memory Reconsolidation, Anthony Murkar, Pam Kent, Christian Cayer, Jon James, Tony Durst, Zul Merali

Brain and Mind Institute

Background: Δ9-Tetrahydrocannabinol (THC, a CB1 receptor agonist) and Cannabidiol (CBD, a non-competitive antagonist of endogenous CB1 and CB2 ligands) are two primary components of Cannabis species, and may modulate fear learning in mammals. The CB1 receptor is widely distributed throughout the cortex and some limbic regions typically associated with fear learning. Humans with posttraumatic disorder (PTSD) have widespread upregulation of CB1 receptor density and reduced availability of endogenous cannabinoid anandamide, suggesting a role for the endocannabinoid system in PTSD. Pharmacological blockade of memory reconsolidation following recall of a conditioned response modulates the expression of learned fear and may represent …

Stress And Eating: A Dual Role For Bombesin-Like Peptides, Zul Merali, S. Graitson, J. C. Mackay, P. Kent

Brain and Mind Institute

The current obesity "epidemic" in the developed world is a major health concern; over half of adult Canadians are now classified as overweight or obese. Although the reasons for high obesity rates remain unknown, an important factor appears to be the role stressors play in overconsumption of food and weight gain. In this context, increased stressor exposure and/or perceived stress may influence eating behavior and food choices. Stress-induced anorexia is often noted in rats exposed to chronic stress (e.g., repeated restraint) and access to standard Chow diet; associated reduced consumption and weight loss. However, if a similar stressor exposure takes …
