Dementia threat might enhance with long-term use of acid reflux disease medication

Individuals who take acid reflux disease drugs referred to as proton pump inhibitors for four-and-a-half years or extra might have a better threat of dementia in comparison with individuals who don’t take these drugs, based on new analysis revealed within the August 9, 2023, on-line situation of Neurology®, the medical journal of the American Academy of Neurology. This research doesn’t show that acid reflux disease medication trigger dementia; it solely reveals an affiliation.

Acid reflux disorder is when abdomen acid flows into the esophagus, often after a meal or when mendacity down. Individuals with acid reflux disease might expertise heartburn and ulcers. Individuals with frequent acid reflux disease might develop gastroesophageal reflux illness, or GERD, which may result in most cancers of the esophagus.

Proton pump inhibitors scale back abdomen acid by concentrating on the enzymes within the abdomen lining that produce that acid.

“Proton pump inhibitors are a useful gizmo to assist management acid reflux disease, nonetheless long-term use has been linked in earlier research to a better threat of stroke, bone fractures and power kidney illness,” stated research writer Kamakshi Lakshminarayan, MBBS, PhD, of the College of Minnesota College of Public Well being in Minneapolis, and a member of the American Academy of Neurology. “Nonetheless, some individuals take these medication often, so we examined if they’re linked to a better threat of dementia. Whereas we didn’t discover a hyperlink with short-term use, we did discover a larger threat of dementia related to long-term use of those medication.”

The research included 5,712 individuals, age 45 and older, who didn’t have dementia firstly of the research. They’d a median age of 75.

Researchers decided if contributors took acid reflux disease medication by reviewing their drugs throughout research visits and through yearly telephone calls. Of the contributors, 1,490 individuals, or 26%, had taken the medication. Individuals had been then divided into 4 teams based mostly on whether or not they had taken the medication and for a way lengthy, as follows: individuals who didn’t take the medication; those that took the medication for as much as 2.8 years; those that took them for two.8 to 4.4 years; and individuals who took them for greater than 4.4 years.

Individuals had been then adopted for a median period of 5.5 years. Throughout this time, 585 individuals, or 10%, developed dementia.

Of the 4,222 individuals who didn’t take the medication, 415 individuals developed dementia, or 19 instances per 1,000 person-years. Particular person-years symbolize each the variety of individuals within the research and the period of time every particular person spends within the research. Of the 497 individuals who took the medication for greater than 4.4 years, 58 individuals developed dementia, or 24 instances per 1,000 particular person years.

After adjusting for components akin to age, intercourse and race, in addition to health-related components akin to hypertension and diabetes, researchers discovered individuals who had been taking acid reflux disease medication for greater than 4.4 years had a 33% larger threat of growing dementia than individuals who by no means took the medication.

Researchers didn’t discover a larger threat of dementia for individuals who took the medication for fewer than 4.4 years.

“Extra analysis is required to substantiate our findings and discover causes for the attainable hyperlink between long-term proton pump inhibitor use and a better threat of dementia,” stated Lakshminarayan. “Whereas there are numerous methods to deal with acid reflux disease, akin to taking antacids, sustaining a wholesome weight, and avoiding late meals and sure meals, totally different approaches might not work for everybody. It will be significant that folks taking these drugs communicate with their physician earlier than making any adjustments, to debate one of the best remedy for them, and since stopping these medication abruptly might lead to worse signs.”

A limitation of the research was that contributors had been requested every year about remedy use, so researchers estimated use between annual check-ins. If contributors stopped and restarted acid reflux disease medication in between check-ins, estimation of their use might have been inaccurate. The authors had been additionally unable to evaluate if contributors took over-the-counter acid reflux disease medication.

The research was supported by the Nationwide Institutes of Well being, together with the Nationwide Coronary heart, Lung, and Blood Institute.
