If you’re checking the headline “Common back-pain drug may be linked to higher dementia risk, large study finds,” the claim needs some important context.
What the evidence actually shows
Some observational studies have found an association between certain painkillers and dementia, but this doesn’t establish that the drug causes dementia.
For example, a large UK Biobank study of 194,758 people with chronic pain found higher dementia risk among people regularly using aspirin, paracetamol (acetaminophen), or multiple NSAIDs. However, ibuprofen was not significantly associated with higher dementia risk in that study.

The broader evidence is also inconsistent. A 2025 prospective study found that short- and intermediate-term NSAID use was associated with a small increase in dementia risk, while long-term use was actually associated with a lower risk.

A newer 2026 analysis similarly reported lower dementia prevalence among users of some NSAIDs, including diclofenac and naproxen.

The important takeaway
Don’t stop a prescribed pain medication because of a headline alone. Dementia risk is influenced by many factors, including age, cardiovascular health, chronic pain itself, and other medications. Observational studies can also be affected by confounding—for example, people taking painkillers may differ from non-users in ways that independently affect dementia risk.
If you give me the name of the back-pain drug in the article (such as ibuprofen, diclofenac, naproxen, or paracetamol), I can check the specific study and tell you how large the reported risk was and whether the evidence suggests causation or merely an association.
