Back Pain Pill or Hidden Cognitive Threat? New Study Links Gabapentin to Dramatic Rise in Dementia Risk.
What if the pill millions take for back pain is quietly clouding the mind?
Gabapentin—once hailed as a neurological breakthrough for epilepsy and nerve pain—has become a household prescription. But now, unsettling new research suggests the drug may be silently increasing the risk of dementia, especially with prolonged use.
Despite its popularity, gabapentin has flown under the radar. But a new study out of the U.S. suggests it’s time to take a much closer look—especially for patients using it regularly.
The Hidden Cost of Relief.
Prescribed under brand names like Neurontin, gabapentin was originally developed to calm overactive nerve activity in epilepsy patients. Over time, it became a go-to treatment for nerve-related pain, including sciatica, post-surgical discomfort, and chronic lower back pain.
But now, scientists at Case Western Reserve University have uncovered a troubling pattern.
After analyzing more than 26,000 American medical records spanning two decades (2004–2024), researchers found that:
Patients who filled six or more gabapentin prescriptions had a 29% higher risk of developing dementia.
Correlation, Not Causation—Yet
Importantly, the study doesn’t prove that gabapentin causes dementia. It simply reveals a strong association.
Dr. Leah Mursaleen of Alzheimer’s Research UK urged caution, pointing out that the study didn’t track dosage levels or treatment duration—and that all participants were already dealing with chronic pain, which can contribute to mental decline independently.
- Professor Tara Spires-Jones of the University of Edinburgh agreed, emphasizing that low physical activity, often linked to chronic pain, is a well-known risk factor for dementia and wasn’t fully accounted for.
