Posttraumatic stress disorder (PTSD) can follow traumatic events, but the share of people affected depends on the population studied. Global estimates suggest about 8%–10% will experience PTSD in their lifetime, while trauma-exposed groups show about 10% prevalence. Here, you’ll explore how PTSD rates vary, how it overlaps with conditions like traumatic brain injury and substance use, and where treatment gaps show up—then look at therapies with the strongest evidence for symptom relief.
Key Takeaways
- 12.6% of veterans of the wars in Iraq and Afghanistan reported PTSD symptoms (2013–2014)
- About 8%–10% of people will experience PTSD at some point in their lives (global estimate)
- In a meta-analysis, the prevalence of PTSD was 10.0% among trauma-exposed populations
- The 2017–2019 U.S. survey period estimate implies millions of adults with PTSD; 3.6% correspond to about 9.0 million adults (calculated from survey prevalence and U.S. adult population estimates in the study)
- VA reports over 1 million veterans received services for PTSD and related conditions (annual utilization counts reported in VA data products)
- PTSD-related conditions account for 2.2% of all DALYs globally (Global Burden of Disease estimate for mental disorders including PTSD-related disorders, quantified)
- Approximately 9% of veterans have PTSD in a given year (U.S. veterans estimate)
- 60% of veterans who receive VA care for PTSD have access to evidence-based psychotherapy
- Approximately 40%–50% of patients with PTSD who receive treatment do not achieve full remission
- 37% reduction in PTSD symptom severity with cognitive processing therapy (CPT) in a meta-analysis
- Imaginal exposure therapy produced a moderate effect size for PTSD symptom reduction (Hedges g ≈ 0.69) in a meta-analysis
- Eye movement desensitization and reprocessing (EMDR) showed a moderate-to-large effect on PTSD symptoms (Hedges g ≈ 0.82) in a meta-analysis
- The 2024 WHO ICD-11 diagnostic criteria include PTSD as a distinct disorder category
- In the U.S., 88% of people with PTSD have at least one other mental health condition (comorbidity rate reported in epidemiologic studies using NESARC)
- In the same NESARC study, PTSD was comorbid with alcohol use disorder in 32.0% of cases
PTSD affects millions worldwide and often goes untreated, despite therapies like CPT and EMDR offering meaningful symptom relief.
