MINNEAPOLIS — Using certain acid reflux medications for an extended period of time may raise a patient’s risk of dementia by up to 33 percent, a new study warns. Researchers working with the American Academy of Neurology found that individuals who consumed proton pump inhibitors (PPIs) for over four-and-a-half years saw their likelihood of developing this serious cognitive condition increase significantly.
Acid reflux occurs when stomach acid enters the esophagus, commonly after meals or while someone is in a reclined position. Symptoms can include heartburn and ulcers. Recurring acid reflux may escalate to gastroesophageal reflux disease (GERD), which has the potential to cause esophageal cancer.
According to the National Institutes of Health, GERD affects between 18 and 28 percent of the U.S. population. PPIs function by inhibiting enzymes in the stomach lining responsible for acid production. The researchers clarify that their study doesn’t establish a direct relationship between taking acid reflux medications and the onset of dementia, but it does show a correlation.
“Proton pump inhibitors are a useful tool to help control acid reflux, however, long-term use has been linked, in previous studies to a higher risk of stroke, bone fractures, and chronic kidney disease,” says study author Professor Kamakshi Lakshminarayan Ph.D., of the University of Minnesota School of Public Health in Minneapolis, in a media release. “Still, some people take these drugs regularly, so we examined if they are linked to a higher risk of dementia. While we did not find a link with short-term use, we did find a higher risk of dementia associated with long-term use of these drugs.”

The research encompassed over 5,700 participants, 45 and older, none of whom had dementia at the start of the study. The average age of participants was 75.
To examine acid reflux medication intake, the team scrutinized participants’ medications during study visits and annual telephone checkups. Among them, 1,490 (26%) had consumed these drugs. They were subsequently categorized based on the duration of their medication usage.
Throughout the average follow-up of approximately 5.5 years, 585 participants (10%) developed dementia. In an adjusted analysis considering age, sex, race, and health concerns like hypertension and diabetes, the study found that participants consuming acid reflux drugs for more than 4.4 years had a 33-percent elevated risk of dementia onset compared to non-users. Notably, taking these drugs for fewer than 4.4 years did not increase dementia risk.
“More research is needed to confirm our findings and explore reasons for the possible link between long-term proton pump inhibitor use and a higher risk of dementia,” concludes Prof. Lakshminarayan.
Which acid reflux drugs are PPIs?
Proton pump inhibitors are available under many names and brands. While most of these drugs work equally well, their side-effects may vary from drug to drug. PPIs include:
- Omeprazole (Prilosec), available over-the-counter (without a prescription)
- Esomeprazole (Nexium), available over-the-counter
- Lansoprazole (Prevacid), available over-the-counter
- Rabeprazole (AcipHex)
- Pantoprazole (Protonix)
- Dexlansoprazole (Dexilant)
- Zegerid (omeprazole with sodium bicarbonate), available over-the-counter (without a prescription)
The study is published in the journal Neurology.

Junk science – It works too well so lets create some hysteria and get it Black Labeled just like VIOXX!
Do a real study on the drug’s direct effects and find out the scientific reason the drug acts the way it does and leave the statistical Mumbo Jumbo out of it…
Woops, have been taking Omeprazole daily for at least 20 years continuously. 80 years old.
These studies focus on a single variable and then look at dementia incidence. What is dementia? Essential waste proteins in the brain. What cleans dementia? A process initiated by changes in the body such as a slowing/cooling digestive tract which stimulates a pressure washing process in the ventricles of the brain. If the pressure washing process is not done well, proteins build up. What makes the pressure process not be done well? Well one as it relates to this article is the digestive tract cooling by a degree. This means eating before bed, taking meds that prolong digestion (antacid meds, ppihibs), sleep disorders, stress, alternative work schedules, and many other variables. Instead of focusing on a drug that indirectly contributes to dementia focus on the many factors that interrupt or negatively impact this pressure washing process.
You’re the best! 👏
So or we get cáncer in the esophagus or dementia, either way we are screwed..
Apples are bad for IBS. Makes it worse. Guess you didn’t think about that
What Famotidine 20 mg??
What about Famotidine 20 mg??
Seems like no matter what it is that you use to cure one problem they always say it could cause another…
I take nexium every morning for acid reflux and will not discontinue using it and if it causes dementia well then at least if I have dementia I probably won’t know I have dementia. 😁
I was just thinking exactly what you wrote. I could use a period of complete lack of awareness, especially at this point in my life.
Big Pharma is a mess. Instead of being leaders in cures they just want to put a bandaid on everything. What ever happened to do no harm. It’s time to be real doctors with real solutions. This is why they are so afraid of doctors that use natural medicine and they really get results. And they use testing that is actually effective. I don’t trust them anymore.
