Researchers from the University of Minnesota in Minneapolis explored whether long-term use of proton pump inhibitors for heartburn might be linked to an increased risk of dementia. The investigation appeared in a neurology-focused journal, underscoring the growing interest in how chronic medications for common conditions could impact brain health over time.
The study followed 5,712 adults who were 45 and older and did not have dementia at the start. The average age of participants was about 75. About a quarter of the group, 26 percent, were taking proton pump inhibitors, medicines designed to reduce stomach acid. Examples include omeprazole and rabeprazole. Over roughly five and a half years, dementia developed in 10 percent of participants overall, providing a basis for examining potential associations between acid-suppressing therapy and cognitive outcomes.
Among 4,222 individuals who did not use proton pump inhibitors, 415 developed dementia during follow-up. In contrast, of the 497 participants who used acid-reducing medications, 58 were diagnosed with dementia. The researchers adjusted for several influencing factors, including age, gender, prior health history, and conditions such as hypertension and diabetes. After these adjustments, they observed that longer exposure to acid-suppressing drugs, specifically more than 4.4 years, was associated with a 33 percent higher risk of dementia compared with those who did not take these medications. This finding suggests a potential link but does not prove causation. Some caution is noted because other unmeasured factors could contribute to the observed association.
When exposure was kept under 4.4 years, no increased dementia risk emerged in the analysis. This nuance highlights the importance of duration of use when interpreting potential associations between proton pump inhibitors and cognitive outcomes. Proton pump inhibitors are commonly prescribed to manage reflux disease, or GERD, a condition characterized by the reflux of stomach acid into the esophagus. Symptoms often include frequent heartburn, which can worsen after meals or when lying down. If GERD is left untreated, there can be enduring discomfort and, in some cases, concerns about esophageal health, including a heightened risk for cancer. The study’s context emphasizes the balance clinicians seek between relief from GERD symptoms and monitoring long-term effects of prolonged therapy.
Previous research has linked long-term PPI use with other health concerns, such as an elevated risk of stroke, bone fractures, and chronic kidney disease. People can often manage GERD with lifestyle changes like maintaining a healthy weight and avoiding late meals or particular trigger foods, though medication remains necessary for many. The current study does not establish that proton pump inhibitors cause dementia; it identifies an association that warrants further investigation. It also notes that abruptly stopping these medications could worsen GERD symptoms for some patients, a factor clinicians consider when planning dose and duration. The authors emphasize the need for more studies to confirm their findings and to explore the underlying mechanisms that might connect prolonged PPI use with dementia risk.

In the broader conversation about brain health and chronic disease management, this research adds a piece to the puzzle about how long-term drug therapy intersects with aging. It invites clinicians and patients to engage in informed discussions about treatment duration, symptom control, and monitoring strategies. While the findings are notable, they should be interpreted as part of a larger body of evidence that continues to evolve with new data and analyses. The overall message remains clear: for those using proton pump inhibitors over extended periods, ongoing medical supervision and periodic reevaluation of treatment necessity are prudent steps as part of comprehensive care for GERD and related conditions.

The pursuit of answers continues, with future studies aiming to clarify the potential links between long-term acid suppression and cognitive health while considering a wide range of contributing factors that influence dementia risk. The efforts reflect a cautious and responsible approach to translating observational findings into practical, patient-centered care. (University of Minnesota study, Neurology)
