"In many parts of Africa, if you are poor and mentally ill, your chances of getting adequate treatment are close to zero," Dr. Karlee Silver of Grand Challenges Canada says in a news release.
Participants—86% of whom were women—were among the most vulnerable, with 70% having a history of domestic violence or illness, and more than 40% were HIV positive.
