The field of global mental health faces important challenges. Access to mental health services is grossly inadequate in many low- and middle-income countries (LMICs) despite the heavy burden of violent conflict and the association between exposure to human and natural disasters in many LMICs and mental health problems such as depression, anxiety, and traumatic stress reactions. Today, the percentage of individuals with severe mental disorders who remain untreated is estimated to be upwards of 97% in some countries, and even in high-income countries, there are vulnerable populations who have similarly unmet needs.
