Trauma and posttraumatic stress disorder (PTSD) are common among psychiatric and criminal populations, so, after administering a self-report surgery, one study found that most insanity acquittees experienced trauma (86%, averaging 11 events) and ACEs (76%, averaging 3 types). The most commonly experienced traumas were sudden death of a loved one, witnessed death or serious injury, adult physical assault, and motor vehicle accident. Furthermore omen were significantly more likely to experience any ACE (especially witnessing domestic violence, household members with mental illness, emotional abuse, and emotional neglect) and adult sexual assault. 

PTSD and the insanity defense

Among those who were hospitalized after their plea, most are young men diagnosed with a psychotic disorder. The majority were hospitalized in general psychiatric hospitals, and only 13% were admitted to maximum-security units, with both having an average stay of 13 months. One set of results show that 73% of the patients had already been hospitalized prior to their NRCMD hospitalization. The rehospitalization rate within 5 years of discharge from NCRMD psychiatric hospitalization was 62%.
