If you’re a veteran with service-connected PTSD who’s been diagnosed with sleep apnea, you’re not alone – and more importantly, your sleep apnea may qualify for additional VA compensation. Research shows veterans with PTSD are 3-4 times more likely to develop sleep apnea than those without. This guide explains the connection and how to build a winning secondary claim.
The PTSD-Sleep Apnea Connection
What the Research Shows
Higher risk of sleep apnea in veterans with PTSD
Multiple peer-reviewed studies confirm that PTSD significantly increases the risk of developing obstructive sleep apnea (OSA). This isn’t coincidence – it’s a medically recognized connection with multiple biological mechanisms.
Veterans with PTSD experience physiological changes that directly contribute to sleep apnea development. The constant state of hyperarousal, stress hormone imbalances, and disrupted sleep architecture create the perfect storm for breathing disorders during sleep.
How PTSD Causes Sleep Apnea
1. Hyperarousal & Sleep Disruption
PTSD keeps your nervous system in constant “fight or flight” mode, preventing deep, restorative sleep stages where breathing naturally regulates.
2. Neurobiological Changes
PTSD alters brain regions controlling breathing and sleep, including the amygdala and hippocampus, disrupting normal respiratory patterns.
3. Increased Inflammation
Chronic PTSD triggers systemic inflammation, contributing to airway swelling and increased risk of obstructive events.
4. Weight Gain from Medications
Many PTSD medications cause weight gain, a primary risk factor for sleep apnea. Common culprits include certain antidepressants and mood stabilizers.
5. Substance Use
Self-medication with alcohol or sedatives to manage PTSD symptoms can relax throat muscles excessively, worsening apnea.
6. Avoidance of CPAP
PTSD sufferers often struggle with CPAP masks due to claustrophobia or feeling trapped, leading to untreated apnea.

Building Your Secondary Claim
Step-by-Step Strategy
Establish PTSD Service Connection
Ensure your PTSD is already service-connected and rated by the VA. This is your primary condition.
Get a Sleep Study
Obtain a polysomnography (sleep study) diagnosing sleep apnea. Document AHI (Apnea-Hypopnea Index) scores.
Document the Timeline
Show that sleep problems began or worsened after PTSD diagnosis. Include spouse statements about snoring/gasping.
Gather Medical Evidence
Collect all sleep clinic records, CPAP compliance data, and any references to sleep issues in mental health records.
Obtain a Nexus Letter
Get a medical opinion linking your sleep apnea to PTSD, citing medical literature and your specific case.
File Your Claim
Submit VA Form 21-526EZ with all supporting evidence, clearly stating sleep apnea as secondary to PTSD.

Common Reasons for Denial (And How to Avoid Them)
Pitfalls to Avoid
1. Weak Medical Opinion: Generic nexus letters without specific medical rationale often fail. Ensure your provider explains the biological mechanisms.
2. Timeline Issues: If sleep apnea was diagnosed before PTSD, you’ll need to show aggravation beyond natural progression.
3. Weight as Sole Cause: VA may blame weight alone. Counter this by showing PTSD’s role in weight gain or other mechanisms.
4. Lack of Treatment Compliance: Poor CPAP compliance can hurt your claim. Document any PTSD-related difficulties using CPAP.
Sample Nexus Letter Language
A strong nexus letter should include language similar to:
“Based on my review of Mr. [Name]’s medical records and current medical literature, it is at least as likely as not (50% or greater probability) that his obstructive sleep apnea is secondary to his service-connected PTSD. The hyperarousal state characteristic of PTSD disrupts normal sleep architecture and respiratory patterns. Additionally, his PTSD medications have contributed to weight gain, a known risk factor for OSA. The temporal relationship between his PTSD diagnosis and subsequent sleep apnea development further supports this connection.”
Real Veteran Success Story
“I struggled with PTSD for years before being diagnosed with sleep apnea. My wife had been telling me I stopped breathing at night, but I thought it was just part of my nightmares. Once I understood the connection and filed a secondary claim with a strong nexus letter, I was approved for 50% for sleep apnea. That extra compensation has made a huge difference in affording treatment for both conditions.” – Marine Veteran, 2021
Next Steps
- Get Evaluated: If you have PTSD and suspect sleep apnea, request a sleep study from your VA provider
- Document Everything: Start keeping a sleep diary noting disturbances, daytime fatigue, and PTSD symptom correlation
- Seek Treatment: Show the VA you’re actively addressing both conditions
- Build Your Case: Gather all evidence showing the connection between your conditions
- Get Expert Help: Consider a professional evaluation for a strong nexus letter
