sample nexus letter for sleep apnea secondary to ptsd

Dear Sir/Madam,

I am writing this letter to provide a medical opinion on the potential relationship between your service-connected post-traumatic stress disorder (PTSD) and your current diagnosis of obstructive sleep apnea (OSA).

It is my professional medical opinion, based on my training, education, and experience, that there is a direct link between your PTSD and OSA. Studies have shown that individuals with PTSD have a higher risk of developing OSA due to the heightened physiological and psychological arousal associated with the disorder. The hyperarousal can lead to changes in breathing patterns, which may result in the onset of OSA.

Your medical records indicate that you were diagnosed with PTSD during your military service. Your medical history shows that you have been experiencing symptoms such as nightmares, flashbacks, and difficulty falling and staying asleep. These symptoms are consistent with the diagnosis of PTSD and have been shown to increase the risk of developing OSA.

In my professional opinion, it is more likely than not that your current diagnosis of OSA is secondary to your service-connected PTSD. The relationship between these conditions is supported by the current medical literature, as well as your medical history and current symptoms.

Please feel free to contact me if you have any further questions or require additional information. Thank you for allowing me to provide this medical opinion.

Sincerely,

[Medical Professional’s Name]
