Question: does omeprazole cause memory loss?
Answer: 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.
