“Safer” Pain Pill’s HIDDEN Brain Risk

A widely used back pain medication, long considered a safer alternative to opioids, may quietly raise the risk of dementia and cognitive decline in adults under 65—a finding that could upend how millions manage chronic pain.

Key Points

Gabapentin, prescribed for chronic low back pain, is linked to a significantly increased risk of dementia and mild cognitive impairment, especially in adults aged 18–64, according to a large national study.
The risk rises with the number of prescriptions—patients with 12 or more gabapentin prescriptions face an even higher likelihood of cognitive problems.
This is an observational study; it shows association, not causation, and confounding factors may be at play.
Experts recommend closer cognitive monitoring for patients on gabapentin, but no immediate changes to prescribing guidelines have been made.
The findings could influence future pain management strategies, especially as gabapentin has been a go-to drug in the fight against opioid addiction.

The Rise of Gabapentin in Chronic Pain Management

Gabapentin, originally developed to treat epilepsy, became a cornerstone of chronic pain management as concerns over opioid addiction escalated in the early 2000s. Physicians turned to gabapentin for neuropathic pain, including chronic low back pain, attracted by its lower risk of addiction and overdose. Over the past two decades, prescriptions soared—millions now rely on it for daily relief. But the long-term effects, especially on brain health, remained unclear, particularly in younger adults not typically considered at risk for dementia.

Previous studies on gabapentin’s cognitive effects were inconclusive, often limited by small sample sizes or lack of age-specific analysis. Most warnings focused on short-term side effects like dizziness or drowsiness, not neurodegeneration. The medical community largely viewed gabapentin as benign compared to opioids, a perception now under scrutiny.

New Evidence: Dementia Risk in Non-Elderly Adults

The recent study, published in July 2025 in Regional Anesthesia & Pain Medicine, analyzed electronic health records from 68 U.S. healthcare organizations via the TriNetX database, covering millions of patient-years from 2004 to 2024. Researchers used advanced statistical methods to match patients on gabapentin with similar patients not taking the drug, aiming to isolate gabapentin’s effect from other variables.

The results were striking: adults prescribed gabapentin for chronic low back pain had a significantly higher risk of developing dementia or mild cognitive impairment within 10 years, with the risk most pronounced in those aged 18–64. The more frequently gabapentin was prescribed, the greater the risk—a dose-response relationship that adds weight to the findings. This challenges the assumption that gabapentin is a risk-free alternative to opioids, especially for younger patients seeking long-term pain relief.

Expert Reactions and Clinical Implications

Leading neurologists and pharmacologists have responded with cautious concern. Prof. Ian Maidment of Aston University notes that while the study shows an association, it does not prove gabapentin causes dementia—other factors, such as the underlying pain condition or concurrent medications, could contribute. Prof. Martin Prince of King’s College London acknowledges the robust methodology but highlights possible confounding and the need for further research.

Despite these caveats, experts agree that clinicians should monitor cognitive function in patients on gabapentin, particularly those with multiple prescriptions. No regulatory agency has yet issued new guidelines, but the medical community is paying close attention. The study’s publication has already triggered media coverage and patient inquiries, with some individuals questioning whether they should continue their medication.

The findings arrive at a delicate moment. Chronic low back pain remains a leading cause of disability worldwide, and gabapentin prescriptions are at an all-time high. If prescribing patterns shift, patients and providers may need to reevaluate pain management strategies, balancing the need for relief against newly recognized risks.

Broader Impact and What Comes Next

The implications extend beyond individual patients. Pharmaceutical companies with a stake in gabapentin sales may face scrutiny, and healthcare systems could see increased costs if cognitive monitoring becomes standard practice. Policymakers and guideline committees will likely debate whether to adjust recommendations, weighing the benefits of pain control against potential long-term cognitive harm.

For now, the message to patients is one of vigilance, not panic. Those taking gabapentin should discuss concerns with their healthcare provider, but abrupt discontinuation without medical supervision is not advised. The study underscores the importance of ongoing research into the long-term effects of commonly prescribed medications, especially as the population ages and chronic conditions become more prevalent.
