Which specific condition is considered under presumptive service for veterans with 90 days of continuous active service?

The condition considered under presumptive service for veterans who have served for at least 90 continuous days on active duty is Amyotrophic Lateral Sclerosis (ALS). This designation allows veterans who develop this condition to receive benefits without needing to prove a direct link between their illness and their service.

The recognition of ALS as a presumptive condition stems from research indicating that veterans are at a higher risk for developing the disease compared to the general population. This acknowledgment is anchored in the understanding of the unique exposures and experiences veterans may have faced during their service, which can contribute to the onset of conditions like ALS.

In contrast, while lung cancer, chronic fatigue syndrome, and fibromyalgia are significant health concerns and may also have service-related considerations, they do not fall under the same presumptive service recognition as ALS for veterans who have served the specified duration. This delineation reflects the specific legislative and medical determinations made regarding the associations between certain conditions and military service.
