Apublished in Neurology found an association between long–term proton-pump inhibitors (PPI) use and dementia. This was an observational study and does not prove that acid reflux drugs cause dementia.
“In this study, the authors note that long-term PPI use, defined as more than 4.5 years of use, was associated with dementia. It is important to note, however, that this does not necessarily mean that PPIs cause dementia. With observational studies, there is an inherent risk of bias and confounding, as the authors report. Some of these confounders include Helicobacter pylori status, vitamin B12 deficiency, depression, and socioeconomic status,” said Fouad J. Moawad, MD, graduate of theand gastroenterologist at Scripps Health in San Diego. A of Mass General Brigham, Boston, examined the association between proton pump inhibitor use and cognitive function in women. The investigators found no “convincing association between PPI use and cognitive function. Our data do not support the suggestion that PPI use increases dementia risk.”
A newby Raaj S. Mehta and colleagues also studied this issue and concluded that in adults 65 years of age or older, PPIs were not associated with dementia or decline in cognition over time. These data provide reassurance about the safety of long-term use of PPIs among older adults.
The headlines may be confusing for patients. Here are AGA’s three talking points for communicating with patients about PPIs:
Talk to your doctor, before making any changes to your medication.
You have been prescribed PPIs for a reason, to treat a diagnosed medical condition. We can discuss the reason for your prescription, the dose and the timeframe for treatment.
Consider lifestyle modifications.
These may reduce or eliminate the need for PPIs for long-term use. These may include weight loss, avoiding tobacco or a change in your eating patterns. We can work together to determine the changes that are right for you.
Keep in touch.
Research continues to be done on PPI use. Current research recommends that patients who have a diagnosed condition that is helped by PPIs should stay on them, as benefits can outweigh risks.
