Proton pump inhibitors (PPIs) are medications used to treat digestive problems such as ulcers and reflux disease by reducing the body’s production of the acid that helps us digest food. Ulcers are sores that develop on the lining of our digestive system; when they develop in the upper part of the small intestine they are called “duodenal ulcers.” Reflux disease is a condition in which stomach acid or other fluids in the digestive system irritate our food pipe, also known as the esophagus.
Recently, safety questions about these medications have been raised in several studies. These studies suggested that PPIs increased the risk for dementia and Alzheimer’s disease in people 75-years-old or older. Noting that the prescription of PPIs is on the rise among middle-aged and older adults, a team of researchers designed a new study to examine PPIs and the risk of dementia, mild cognitive impairment, and Alzheimer’s disease. They published their study in the Journal of the American Geriatrics Society. The researchers also examined whether people with mild cognitive impairment who took PPIs were at higher risk for developing dementia or Alzheimer’s disease. Continue reading
