According to the Tennessee Department of Mental Health and Substance Abuse Services, more than 400,000 Tennesseans experienced a serious emotional disturbance or mental illness in 2017. The department also found therapy deserts in rural areas of the state, meaning that options for mental health treatment are limited. Similar problems exist for Tennessee's homeless population. In this October edition of Dialogue, WUOT's Hannah Martin speaks with Dr. Parinda Khatri and Dr. David Patterson about the prevalence of mental illness in Tennesseans, and what resources exist for support.
