This document discusses mental illness and the criminal justice system. It provides background on the history of how mental illness was treated, noting that until the mid-1900s there was little medical attention given to the mentally ill. It then explains that today around 15-24% of prisoners and jail inmates meet the criteria for a psychotic disorder. However, prisons are often ill-equipped to properly treat mental illness, and inmates with mental illness face higher risks of solitary confinement, assault, suicide or self-harm. The document concludes by noting that states that have expanded Medicaid under the Affordable Care Act have seen reduced crime and incarceration rates as more mentally ill individuals can access free treatment services.
