What causes death in ALS — what patients should watch

Key Takeaway

Many deaths in people with ALS are tied to lung problems and accidents, some of which might be preventable with careful care.

What They Found

Researchers looked at U.S. death records for people with ALS from 2011–2014 and counted other causes listed on the certificates besides ALS. They found ALS was listed alone in about 46% of cases, meaning many records did not list other contributing problems. The most common other causes were breathing failure (when the lungs stop working well), heart disease, pneumonia (lung infection), and pneumonitis (lung inflammation from things like food or liquids going into the lungs). People with ALS were more likely than others to have deaths linked to falls and accidents, and those were often tied to injuries. Overall, the study shows which health problems happen most often near death for people with ALS, which can point to ways to reduce harm or delay death.

Who Should Care and Why

People with ALS and their caregivers should care because knowing the common risks helps prevent them — for example, watching for swallowing problems can lower pneumonia risk, like guarding a stairway to prevent falls. Healthcare providers can use this information to focus on breathing care, heart health, and safe eating or moving routines, much like fixing the weakest links in a chain to keep it from breaking. Care teams can plan for breathing support early (such as devices or therapies that help with breathing) to possibly delay lung failure. Families can make the home safer (grab bars, removing trip hazards) to reduce falls that the study shows are more common. This matters day to day because small changes — like supervised meals or regular breathing checks — may reduce complications and improve comfort.

Important Considerations

The study used death certificates, which sometimes miss or simplify other health problems, so the numbers may not show every issue a person had. Because records list only what the certifier wrote, some preventable causes could be undercounted or listed alone as ALS. This means results point to likely risks but don’t prove that fixing one problem will always change outcomes for every person with ALS.

MS Progression Caregivers Living with MS

Whether you’ve recently been diagnosed with Multiple Sclerosis (MS) or are seeking to broaden your understanding of this complex, neurodegenerative disease, navigating the latest research can feel overwhelming. Studies published in respected medical journals like Annals of clinical and translational neurology often range from early-stage, exploratory work to advanced clinical trials. These evidence-based findings help shape new disease-modifying therapies, guide symptom management techniques, and deepen our knowledge of MS progression.

However, not all research is created equal. Some clinical research studies may have smaller sample sizes, evolving methodologies, or limitations that warrant careful interpretation. For a more comprehensive, accurate understanding, we recommend reviewing the original source material—accessible via the More Details section above—and consulting with healthcare professionals who specialize in MS care.

By presenting a wide range of MS-focused studies—spanning cutting-edge treatments, emerging therapies, and established best practices—we aim to empower patients, caregivers, and clinicians to stay informed and make well-informed decisions when managing Multiple Sclerosis.
