Study links higher ALS rates to Air Force, Navy and Coast Guard veterans and officers

A recent study published in Neurology examined records of almost 10 million veterans who received Department of Veterans Affairs health care from 2000 to 2024, identifying roughly 14,500 individuals diagnosed with amyotrophic lateral sclerosis. The findings indicate that veterans who served in the Air Force, Navy or Coast Guard experienced ALS rates 15 % to 29 % higher than those who served in the Army, while Marine veterans showed a lower incidence.

Officers had a 64 % greater likelihood of developing ALS compared with enlisted personnel, though the research could not pinpoint exact occupational or environmental causes. Prior work suggests exposures such as lead, pesticides and other toxins, and the authors note that officers may encounter distinct stressors like high G-forces, noise, and circadian disruption, whereas enlisted members often face heavy physical exertion and fuel or solvent handling.

Male veterans displayed the most pronounced branch differences, and among the limited number of female veterans, female officers faced a 72 % higher risk than enlisted women. Researchers caution that ALS remains a rare condition and call for further studies to identify the specific factors driving these branch- and rank-related risks.
