Key points
- VA reports that 7% of Veterans have had PTSD in their lifetime, compared with 6% of U.S. adults; among Operations Iraqi Freedom and Enduring Freedom Veterans, the estimates are 15% in the past year and 29% over a lifetime.[1]
- NIDA reports that more than one in ten Veterans have been diagnosed with a substance use disorder; this is a different measure from the estimate that 37–50% of Afghanistan and Iraq War Veterans have been diagnosed with a mental disorder.[2]
- Support is available: call 988 and press 1, text 838255, or use Veterans Crisis Line chat for free, confidential help 24/7.[3]
The honest answer is that there is no one reliable percentage for all veterans and all mental illnesses. Rates change depending on the condition, service era, study method, and time frame. For one well-studied condition, PTSD, VA reports 7% lifetime prevalence among Veterans overall and 15% past-year and 29% lifetime prevalence among Veterans of Operations Iraqi Freedom and Enduring Freedom.[1]
What do the numbers say about PTSD in Veterans?
VA's National Center for PTSD says that 7 out of 100 Veterans have PTSD at some point in their lives, compared with 6 out of 100 U.S. adults. The same VA summary reports 15% past-year PTSD and 29% lifetime PTSD among Veterans of Operations Iraqi Freedom and Enduring Freedom. These figures are not a universal rate for every veteran: service era, exposure, sample, and whether the estimate is past-year or lifetime all matter.[1]
Deployment is associated with higher PTSD risk in some studies, but that does not mean every deployed Veteran develops PTSD. VA notes that studies use different methods and that the people included in a study can affect the result.[1]
What about substance use and other mental-health conditions?
NIDA summarizes separate findings that should not be combined into one prevalence number: more than one in ten Veterans have been diagnosed with a substance use disorder, while an estimated 37–50% of Afghanistan and Iraq War Veterans have been diagnosed with a mental disorder. NIDA also reports that, among recent Afghanistan and Iraq Veterans diagnosed with a substance use disorder, 63% met criteria for PTSD. Each statistic has its own population and measure.[2]
PTSD, depression, anxiety, and substance use problems are all discussed in veteran-health research and care, but it is not accurate to present them as a universal top-three ranking for every Veteran. A diagnosis or symptom can also occur alongside another condition, so a person's experience may not fit one category neatly.[2][4]
Why can military service affect mental health?
Military service can involve deployment, combat exposure, military sexual trauma, injury, grief, and the stress of readjusting to civilian life. Those experiences may affect people differently. VA offers care for PTSD, depression, anxiety-related conditions, substance use problems, and other needs; some services may be available even if you are not enrolled in VA health care.[4]
How can families support a Veteran?
- Listen without judgment and ask what kind of support would feel useful.
- Encourage a conversation with a health professional, Vet Center, or VA mental-health provider.
- Learn about symptoms and treatment options from reliable sources rather than assuming every Veteran's experience is the same.
- Help with practical steps, such as finding a facility, arranging transportation, or joining an appointment if invited.
- If there is immediate danger, call 911 or go to the nearest emergency room. For crisis support, use the Veterans Crisis Line.
Where can Veterans find mental-health care?
VA's mental-health services page explains how to access care for PTSD, depression, substance use, military sexual trauma, anxiety, and other concerns. You can call or walk in to a VA medical center or Vet Center, and some services are available regardless of VA health-care enrollment. For general VA health-benefits guidance, see our guide to VA health care and Medicare and Veterans Medicare FAQ.[4]
