PTSD as a Criminal Defense Introduction Post-traumatic stress disorder (PTSD) is a mental health illness resulting from the aftermath of a traumatic experience in one's life. It was included in the psychiatric nomenclature in 1980 ((Pitman & Sparr 1998). Since PTSD was added in DSM-III, PTSD has been used as a ground for criminal defense, including unconsciousness, diminished capacity, insanity, self-defense, and mitigation of the sentencing. Moreover, the United States appellant courts have recognized PTSD as a valid ground for unconsciousness, insanity, and self-defense (Berger, McNiel & Binder, 2012). The court, as a result, has recognized the testimony cringed to the PTSD as scientifically reliable. This paper will focus on how PTSD is used in criminal defense.
