A new study by Martin Harrow, Thomas Jobe, and Liping Tong found that odds of recovery from “serious mental illness” were six times greater if the patient discontinued antipsychotics within two years. The study followed patients with schizophrenia and affective psychosis (bipolar and depression with psychotic features) diagnoses for 20 years. The study was published in Psychological Medicine.

There is also a helpful review of the paper published in Mad in America.
