The Board denied service connection for obstructive sleep apnea (OSA), finding that the evidence did not support a causal relationship between OSA and either in-service herbicide exposure or any of the Veteran's service-connected conditions, including PTSD and hypertension.
The deciding factor: The evidence was insufficient to establish a causal link between the Veteran's OSA and his service or service-connected disabilities due to factors such as obesity, alcohol use, and other risk factors for OSA that were present regardless of service connection status.
