US Air Force, Navy, and Coast Guard veterans face higher rates of rare nerve disease ALS than other vets, study finds

Veterans who served successful the Air Force, Navy, aliases Coast Guard had amyotrophic lateral sclerosis, aliases ALS, rates 15% to 29% higher than Army veterans, according to a caller study.

The study, published successful the diary Neurology past month, analyzed records for astir 10 cardinal veterans receiving Department of Veterans Affairs healthcare betwixt 2000 and 2024, including astir 14,500 pinch an ALS diagnosis.

Officers were recovered to look a 64% elevated consequence of processing ALS, compared pinch their enlisted counterparts. The researchers did not find whether peculiar subject jobs aliases exposures were responsible for the difference.

ALS, besides known arsenic Lou Gehrig's disease, is simply a degenerative illness that damages the nervus cells that power voluntary movement. Over time, patients suffer the expertise to control muscles that needed to speak, eat, move, and respire independently. It is often difficult to diagnose and is fatal.

"Military work is simply a known consequence facet for the improvement of ALS, but small is known astir what factors whitethorn lend to that risk," Marc Weisskopf, an biology epidemiologist astatine Harvard and 1 of the study authors, said successful a Harvard announcement.

Weisskopf cautioned that ALS is uncommon and the wide consequence of processing it remains small, "so moreover statistically important increases associated pinch branch and rank correspond only humble increases successful consequence among subject personnel."

Previous studies person besides recovered ALS is much communal successful veterans, according to the National Institute of Neurological Disorders and Stroke, possibly because veterans look vulnerability to consequence factors for illustration lead, pesticides, and different toxins. While ALS tin impact each populations, it's much often recovered successful older achromatic men.

What could explicate the branch and rank differences remains unclear. Weisskopf said successful an American Academy of Neurology property merchandise that officers and enlisted unit whitethorn look different activity conditions.

"Officers thin to acquisition much psychosocial stress, pinch pilots experiencing precocious G-forces, sound and vibration arsenic good arsenic circadian disruption, while enlisted unit usually acquisition much utmost beingness exercise, dense weapons usage and handling of fuels and solvents," he said.

Around 46% of veterans pinch an ALS test served successful the Army, astir successful statement pinch the Army's stock of the wide seasoned organization examined,

After accounting for age, sex, race, and ethnicity, antheral Air Force veterans had a 29% higher ALS rate than antheral Army veterans, while antheral Coast Guard veterans had a 26% higher complaint and antheral Navy veterans had a 15% higher rate. Male Marine veterans had a 22% little complaint than Army veterans, researchers found.

Differences were much pronounced among men nether property 61 than among those complete 75.

The researchers said they had constricted expertise to measure differences among women because ALS is truthful uncommon and women dress up a smaller stock of the subject population, conscionable 18%. But among the women who were included, female officers faced a 72% higher consequence compared pinch enlisted women.

"Our findings propose that officers and those serving successful the Air Force, Navy, aliases Coast Guard whitethorn person been exposed to subject environments that summation consequence for ALS," Weisskopf said successful a release. "Future investigation should purpose to place these exposures."
