One of the largest treatment gaps for mental, neurological, and substance use (MNS) disorders in the world can be seen in Sub-Saharan Africa (SSA). According to the World Health Organization (WHO), about 80% of people with serious MNS disorders living in low- and middle-income countries do not receive needed health services. A critical barrier to bridge this treatment gap is the ability to provide adequate human resources for the delivery of essential interventions for MNS disorders.
