Between 1.5% to 3.0% of the population have PTSD in a given year, resulting in about 8 million people with PTSD in the United States. It is estimated that worldwide approximatley 354 million war survivors suffer from PTSD, and this number increases significantly considering other causes of severe trauma exposure.
Current available treatments include different forms of psychotherapy or medications or their combination. However, patients and clinicians often agree that these treatments are inadequate in addressing the wide range of symptoms in PTSD. Importantly, these treatments often do not control the exaggerated suicide risk, and increased medical risks, resulting in decreased life expectancy in PTSD.
