A recent study published in the medical journal Neurology indicates that long-term use of proton pump inhibitors (PPIs), which are taken by millions in the UK to reduce stomach acid, may significantly increase the risk of developing dementia. The research involved 5,712 participants aged 45 and above, all of whom were initially free of dementia. It was found that participants who had used these medications for over 4.4 years were 33% more likely to be diagnosed with dementia compared to those who had never taken them.

The study categorized the participants based on their use of PPIs, with approximately 26% having used the drugs during the research period. As the average age of participants was 75, the implications of this finding are particularly significant for an aging population. The researchers emphasize the importance of monitoring medication use in older adults and considering potential long-term effects on cognitive health.

Given the prevalence of PPIs in treating conditions like acid reflux and peptic ulcers, this study may lead to a reevaluation of how these medications are prescribed. Doctors may need to weigh the benefits of symptom relief against the potential increased risk of dementia, prompting a shift towards alternative treatments or more vigilant patient monitoring, especially among older patients who are often prescribed these common medications.
