acid blockers

Proton pump inhibitors have some mild, treatable side effects. Other reported side effects, such as heart attacks, kidney disease, and dementia are sensationalist and based on weak evidence.
A new study of elderly Germans assessed the possible link between acid-blocking drugs called proton pump inhibitors (PPI) and new-onset dementia. A 44 percent increased risk of dementia was found among those on PPIs long-term, but no cause-and-effect link can be established based upon this study.
