The prevalence of PTSD among veterans varies significantly, influenced by factors such as the nature of their deployment, combat exposure, and unfortunately, gender. In fact, women veterans are 9% more likely to experience PTSD than male veterans due to higher rates of sexual assault and harassment, according to the National Center for PTSD.

Studies also show that PTSD prevalence is notably high among veterans of recent operations, with estimates suggesting that up to 29% of veterans who served in operations Iraqi Freedom and Enduring Freedom may suffer from PTSD. These figures point to the critical need for comprehensive mental health support and resources for veterans, emphasizing the importance of recognizing and treating PTSD symptoms early.

Not all Veterans use VA health care, and we know that PTSD is more common among those who do. One study found that among Veterans using VA care, 23 out of every 100 (or 23%) had PTSD at some point in their lives, compared to 7 out of every 100 (or 7%) of Veterans who do not use VA for health care.

An annual report from VA also offers information about PTSD in Veterans using VA care. Of the 5.8 million Veterans served in fiscal year 2024, about 14 out of every 100 men (or 14%) and 24 out of every 100 women (or 24%) were diagnosed with PTSD.

The incidence of PTSD is not limited to recent conflicts. Veterans of the Gulf War and the Vietnam War also report significant rates of PTSD, with some estimates suggesting that PTSD affects about 30% of Vietnam War veterans.
