This study was conducted on 74 military Service Members with documented PTSD or ADNOS diagnoses.  34 received training and performed Transcendental Meditation, once per day, five days per week for a minimum of 3 months in addition to their traditional therapies. This experimental group showed a decrease in medication reliance and psychological symptom severity compared to the control. This shows that meditation can help stabilize and reduce PTSD symptoms in as little as a month, with increased duration leading to a better response.
