- For patients: People who have a diagnosis of another major mental health condition at the same time, although depression, anxiety, and mild substance use disorder are allowed given how commonly they occur alongside PTSD
- For healthy volunteers (non-patients): People who have a history of any major mental health diagnosis, or who are currently taking any medications that affect mood or brain function
- People who are in severe psychiatric crisis, including anyone who is actively at risk of harming themselves or others
