Is omeprazole linked to dementia?

Is omeprazole linked to dementia?

The patients who had been regularly taking a PPI, such as omeprazole (Prilosec), pantoprazole (Protonix), lansoprazole (Prevacid), esomeprazole (Nexium) and rabeprazole (AcipHex), had a significantly increased risk of incident dementia compared with patients who did not take the medication.

Are PPI linked to Alzheimer’s?

Some experimental18 and clinical19 studies in recent years have found that proton pump inhibitors (PPIs) are associated with an increased risk of dementia and AD.

Is Prevacid linked to dementia?

The study focused on widely used proton pump inhibitors (PPIs) drugs — medicines such as Prevacid, Prilosec and Nexium. Previous studies have suggested the drugs may increase the risk of dementia and Alzheimer’s disease in people aged 75 and older.

Can dementia be triggered?

Dementia is a result of physical changes in the brain, and these can affect the person’s memory, mood and behaviour. Sometimes, behaviour may be related to these changes, but at other times, the behaviour may be triggered by changes in the person’s environment, health or medication.

Do all PPIs cause dementia?

Recent clinical studies have shown that proton pump inhibitors (PPIs) are associated with risk of dementia, including AD. However, a recent case-control study reported decreased risk of dementia.

Does PPI affect memory?

The most common PPIs in use were omeprazole (Prilosec), pantoprazole (Protonix), and esomeprazole (Nexium). All participants were free of dementia at the study’s beginning. Yet, after the eight-year follow-up, chronic PPI users had a 44% increased risk of dementia compared with those who did not take any medication.

Why do proton pump inhibitors cause dementia?

First, PPIs may affect amyloid-beta (Aβ) metabolism, one of the pathological markers of Alzheimer’s disease (AD). There is evidence that PPIs could cross the blood-brain barrier, enhance Aβ levels in the brain and decrease Aβ degradation.

How do PPIs cause dementia?
