National PTSD Awareness Day was officially designated in 2010 by the United States Senate with Senate Resolution 541 of the 111th Congress dedicated to creating awareness regarding PTSD. It was acknowledged annually as June 27. In 2013, the Senate designated the whole month of June as PTSD Awareness Month. In the US, 6.8% of adults will experience PTSD in their lifetimes, with women twice as likely as men to experience it frequently as a result of sexual trauma. Veterans are another group highly likely to experience PTSD during their lives, with Vietnam War veterans at 30%, Gulf War veterans at 10%, and Iraq War veterans at 14%.
