Dr. Gregory Day, an associate professor in the Department of Neurology at the Mayo Clinic, said the theory is still considered plausible.
He reportedly told CBS News that PPIs may “alter enzymes in the brain” responsible for regulating amyloid, a protein strongly linked to the brain damage seen in Alzheimer’s disease.
According to him, the medications may “decrease the level of the body’s chemical that is there to cut off the amyloid in specific ways.”
“In theory, these medications increase amyloid in the brain, increasing the risk of Alzheimer’s disease, and Alzheimer’s is the number one cause of dementia,” he said.
Despite these findings, experts stress that patients should not suddenly stop taking prescribed medications without first speaking with a doctor.
“While there are various ways to treat acid reflux, such as taking antacids, maintaining a healthy weight, and avoiding late meals and certain foods, different approaches may not work for everyone,” Dr. Lakshminarayan said.
“It is important that people taking these medications speak with their doctor before making any changes, to discuss the best treatment for them, because stopping these drugs abruptly may result in worse symptoms.”
