Sleep apnea and Post-traumatic Stress Disorder (PTSD) often co-occur in veterans, creating a complex relationship that impacts veterans’ health and well-being. Characterized by breathing interruptions while sleeping, sleep apnea is common among veterans as a secondary condition to PTSD. A well-documented nexus letter can become essential in some cases for establishing this connection in VA disability claims.
In this insightful blog, we’ll explore the connection between PTSD and sleep apnea, highlight the value of VA nexus letters, and share insight for veterans in pursuit of the benefits they deserve.
Prevalence of Sleep Apnea and PTSD in Veterans
Sleep apnea is a condition where breathing repeatedly stops and starts, disrupting normal sleep patterns. It can lead to serious health problems, including cardiovascular disease, hypertension, and excessive daytime sleepiness. The American Academy of Sleep Medicine estimates that over 25 million adults in the U.S. suffer from obstructive sleep apnea, making it a common disorder.
Veterans typically suffer from the following types of sleep apnea:
- Obstructive Sleep Apnea (OSA): Blockage in the airway due to relaxed throat muscles.
- Central Sleep Apnea (CSA): The brain fails to signal the muscles responsible for controlled breathing.
- Complex Sleep Apnea: A combination of OSA and CSA, often emerging after treatment with a continuous positive airway pressure (CPAP) machine.
On the other hand, PTSD is a mental health condition resulting from traumatic experiences during military service. Veterans with PTSD often deal with the following:
- Nightmares and flashbacks
- Hypervigilance and chronic stress
- Insomnia and poor-quality sleep
The connection between PTSD and sleep apnea lies in the overlapping symptoms. A study of 195 Iraq and Afghanistan veterans found that 69.2% were at high risk for sleep apnea, and the likelihood was greater for those with more severe PTSD symptoms.
How PTSD Contributes to Sleep Apnea
Veterans who claim sleep apnea secondary to PTSD often require well-documented medical research to substantiate their service connection. Several PTSD-related factors can directly or indirectly contribute to the condition:
Chronic Stress and Hyperarousal
PTSD keeps veterans in a constant state of “fight-or-flight,” which can disrupt normal breathing patterns during sleep. This heightened stress increases the likelihood of OSA.
Weight Gain from PTSD Medications
Many medications prescribed for PTSD management, including antidepressants, can cause weight gain in veterans. Excess weight is a significant risk factor for obstructive sleep apnea because it increases pressure on the airway.
Sleep Fragmentation and Insomnia
Post-traumatic stress disorder often causes nightmares and frequent awakenings, leading to fragmented sleep. This can cause breathing irregularities, increasing the risk of obstructive sleep apnea.
Reduced CPAP Compliance
Veterans with PTSD may find continuous positive airway pressure (CPAP) therapy difficult due to claustrophobia or discomfort, which exacerbates untreated sleep apnea.
Lifestyle Changes
PTSD-related anxiety and depression often cause poor eating habits and sedentary behavior, further increasing the risk.
What Is a Nexus Letter for Sleep Apnea Secondary to PTSD? And Why Is it Important?
A nexus letter for sleep apnea secondary to PTSD is a crucial document written by a licensed medical professional. This medical opinion aims to demonstrate that the primary condition has either caused or worsened the veteran’s secondary condition.
While the VA does not mandate a nexus letter for secondary service connection, it is often helpful for claims where sleep apnea was not diagnosed during service or lacks direct military connection.
To strengthen your VA disability claim, a nexus letter for sleep apnea secondary to PTSD should include:
- Provider’s Credentials: Written and signed by a licensed medical professional (e.g., M.D., specialist in respiratory conditions, or pulmonologist) with expertise in VA claims. Their qualifications, specialty, and experience should be outlined.
- A Formal Sleep Apnea Diagnosis: Confirmed through a sleep study.
- Service-Connected PTSD: A documented PTSD diagnosis with an existing VA rating.
- Strong Nexus Opinion: States it is “at least as likely as not” that PTSD caused or aggravated the apnea.
- Evidence-Based Rationale: References peer-reviewed studies, clinical findings, or service records supporting the link.
- Comprehensive Medical Review: Includes sleeping test results, PTSD history, and military and post-service medical records.
- Clear Explanation: Describes how PTSD symptoms, such as chronic stress, nightmares, or medication side effects, contribute to apnea.
By providing expert analysis and supporting evidence, a nexus letter is often vital in proving a link for secondary service connection between PTSD and sleep apnea, helping veterans receive the VA ratings and compensation they deserve.

RE: Nexus Letter for [Mr. Veteran’s Full Name]
To Whom It May Concern,
I am Dr. [Your Full Name], a licensed Pulmonologist, with over [X] years of experience in respiratory conditions and sleep disorders. Based on my expertise, I have reviewed [Veteran’s Name]’s comprehensive medical history, military service records, and current symptoms. It is my professional medical opinion that [Veteran’s Name]’s obstructive sleep apnea (OSA) is at least as likely as not (at least a 50% probability) caused by his service-connected post-traumatic stress disorder (PTSD).
[Veteran’s Name] has a well-documented history of PTSD resulting from prolonged exposure to life-threatening combat situations and witnessing the deaths of fellow service members. His symptoms include chronic insomnia, nightmares, hypervigilance, and intrusive flashbacks, which have been consistently noted in his treatment records. These symptoms significantly disrupt normal sleep architecture, which is an essential factor in developing and exacerbating sleep apnea.
Medical research has established a correlation between PTSD and OSA. The chronic hyperarousal associated with PTSD alters the function of the autonomic nervous system, contributing to airway instability and increased risk of apneic episodes while sleeping. Furthermore, [Veteran’s Name]’s PTSD-related weight gain, resulting from decreased physical activity and emotional eating, has further exacerbated his risk of developing apnea.
The veteran underwent a sleep study on [date], which confirmed a diagnosis of moderate to severe OSA. His PTSD has complicated his treatment with continuous positive airway pressure (CPAP) therapy, as the intrusive nature of the equipment triggers anxiety and discomfort. This demonstrates the interrelationship between the two conditions.
In conclusion, it is my medical opinion that [Veteran’s Name]’s obstructive sleep apnea is at least as likely as not directly linked to his PTSD. This opinion is based on my clinical evaluation, review of medical evidence, and my medical expertise in respiratory and sleep disorders. If any further clarification or information is needed, please feel free to contact me at [phone number] or [email address].
Sincerely,

VA Ratings for Sleep Apnea Secondary to PTSD
The VA rates sleep apnea under Diagnostic Code 6847, and the severity of your symptoms helps determine the percentage rating. Here’s how sleep apnea rating breaks down:
- 0% Rating: The condition is diagnosed, but no significant symptoms are present.
- 30% Rating: Symptoms include daytime hypersomnolence (excessive sleepiness).
- 50% Rating: Requires the use of a CPAP machine or other breathing assistance device.
- 100% Rating: Severe complications, such as chronic respiratory failure or tracheostomy.
The 50% rating is the most common for sleep apnea secondary to PTSD, as veterans often require a CPAP machine.
Combined VA Disability Ratings
If you are already service-connected for PTSD, which often carries a rating of 70%, a 50% sleep apnea can significantly increase your combined disability rating. This increase can lead to higher monthly compensation and eligibility for Total Disability Individual Unemployability (TDIU) benefits.
Considerations to Prove Sleep Apnea Is Secondary to PTSD
- Obtain a Sleep Apnea Diagnosis
Typically the first essential step is to undergo a formal sleep study, also known as polysomnography, without which your VA disability claim cannot move forward. Polysomnography evaluates breathing patterns, heart rate, and oxygen levels, either in a sleep lab or through a home-based test.
- Establish Service-Connected PTSD
For a secondary claim for sleep apnea, having an established service connection for PTSD is an important factor. PTSD acts as the “primary” condition, providing the basis for linking sleep apnea as a secondary condition. Even a 0% PTSD rating can support this connection, as it demonstrates a recognized mental health impact that could contribute to or aggravate sleep apnea.
- Find a Qualified Medical Professional
To write a nexus letter that links your sleep apnea to your service-connected PTSD, look for a medical expert specializing in sleep disorders, psychiatry, or veterans’ disability claims. You can even request a primary care physician, pulmonologist, or any mental health professional. Providers who understand VA nexus requirements will write stronger letters. Your treating provider or your VA healthcare provider may be willing to assist.
- Request a Comprehensive Nexus Letter
For veterans obtaining these reports, the nexus letter should include a detailed medical opinion clearly explaining how PTSD contributes to or aggravates sleep apnea. The strongest nexus letters reference specific symptoms of PTSD, such as chronic hyperarousal, anxiety, or insomnia, that potentially lead to apneic episodes. Sound reports include supporting medical literature or studies linking both conditions to strengthen your claim.
- Supporting Evidence
Supporting evidence plays a crucial role in strengthening a VA claim for sleep apnea secondary to PTSD. Along with a nexus letter, comprehensive documentation can include polysomnography results, military medical records, buddy statements, and a completed Disability Benefits Questionnaire (DBQ) for sleep apnea when applicable. Each piece of evidence may contribute to establishing the connection between the conditions
- Medical records showing treatment for PTSD and sleep apnea.
- Results from your polysomnography.
- Lay statements from loved ones or fellow service members who can describe observed symptoms.
- VA treatment notes documenting overlapping issues like insomnia or breathing difficulties.
- Medical research studies highlighting how PTSD exacerbates the risk of sleep-disordered breathing.
- Complete a Sleep Apnea Disability Benefits Questionnaire (DBQ)
A completed Disability Benefits Questionnaire (DBQ) for sleep apnea offers the VA detailed insights into the condition, including the severity of PTSD symptoms, treatments such as CPAP usage, and the functional impact on daily life. When completed by a qualified physician, the DBQ provides essential information for determining an appropriate disability rating. Combining the DBQ with a nexus letter can provide detailed information to adjudicators by presenting a comprehensive view of the relationship between conditions. It is important to remember that DBQ documents can be provided at little to no-cost at the VA C&P exam or by your treating provider if they are willing to assist.
3 Common Reasons for VA Denials
Lack of a Formal Sleep Study
One of the primary reasons for VA denials of sleep apnea secondary to PTSD claims is the absence of a documented sleep study or diagnosis. Without this, the VA is unlikely to recognize this condition as a legitimate condition, let alone approve it as service-connected. A formal sleep study provides essential medical documentation.
Missing Nexus or Link
Establishing a link between sleep apnea and a service-connected condition, such as PTSD, requires a nexus. A nexus is a link between a medical condition and a veterans service. A nexus letter is a narrative report that aims to demonstrate the nexus. While a nexus must be established, it does not necessarily have to be in the form of a robust letter. A simple statement from a treating provider or the VA C&P examiner can suffice. While VA disability nexus letters are not mandatory, they often become a critical piece of evidence to prove secondary service connection.
Insufficient Medical Evidence
Insufficient medical evidence is a common reason for VA claim denials. Strengthening a secondary service connection for sleep apnea often involves providing comprehensive documentation, including but not limited to the following when applicable: polysomnography results, a nexus letter, military medical records, buddy statements, and a completed Disability Benefits Questionnaire (DBQ) for sleep apnea from a qualified physician. These materials help establish the necessary link between conditions.
Other Conditions Secondary to Sleep Apnea
Sleep apnea, a common service-connected condition among veterans, often contributes to additional health issues that can be claimed as secondary disabilities. Aside from PTSD, veterans may experience significant comorbidities linked to the condition that warrant compensation.
Hypertension is one of the most prevalent conditions secondary to sleep apnea. Interrupted breathing patterns can lead to spikes in blood pressure, putting sustained strain on cardiovascular health.
Heart Disease is another serious concern. Disordered sleeping can exacerbate heart conditions like atrial fibrillation or congestive heart failure due to reduced oxygen levels during sleep.
Diabetes has also been linked to sleep apnea. Disrupted rest patterns can impair glucose metabolism, contributing to insulin resistance and Type 2 diabetes.
Chronic Fatigue and Migraines often result from poor-quality sleep caused by sleep apnea, significantly impairing daily functioning.
Depression and Anxiety Disorders are mental health conditions frequently exacerbated by chronic sleep deprivation, affecting a veteran’s overall well-being.
Lastly, Obesity can be both a cause and a consequence of sleep apnea, creating a cyclical relationship that worsens symptoms.
Veterans experiencing these secondary conditions should document clear medical evidence connecting them to their sleep apnea.
Professional Assistance and Guidance
Secondary service connection claims can be complex, and professional assistance ensures your case is as strong as possible. Consider consulting VA-accredited attorneys, claims agents, or veteran service organizations (VSOs) to guide you through the process. These experts provide legal advice, can assist with sleep apnea nexus letters, and advocate for your rights to secure proper compensation.
Conclusion
Establishing a connection between PTSD and sleep apnea is an important step for veterans seeking VA disability benefits for these related conditions. A well-crafted VA nexus letter, backed by solid medical evidence, can greatly enhance the chances of a successful claim in some cases.
