Gabapentin is widely prescribed to treat chronic nerve pain, seizures, and conditions like restless leg syndrome. While it has proven effective for many patients, recent research has raised concerns about its long-term safety—particularly its potential link to cognitive decline.
A new study led by scientists at Case Western Reserve University found that patients who regularly used gabapentin were significantly more likely to develop dementia or mild cognitive impairment over time. By analyzing the medical records of over 26,000 individuals with chronic low back pain, researchers discovered a notable correlation between repeated gabapentin prescriptions and increased dementia risk.
These findings suggest that while gabapentin remains a useful treatment, healthcare providers should monitor patients carefully and weigh potential cognitive side effects before long-term use.

Study Overview: Investigating Gabapentin and Dementia Risk
A team of scientists from Case Western Reserve University conducted a comprehensive study analyzing medical records of individuals suffering from chronic low back pain. The goal was to evaluate whether gabapentin use correlated with increased incidences of dementia and cognitive impairment.
Their findings, published recently in the journal Regional Anesthesia & Pain Medicine, revealed that patients prescribed gabapentin were significantly more likely to develop dementia over time compared to those who were not prescribed the medication.
According to the researchers:
“Our findings indicate an association between gabapentin prescription and dementia or cognitive impairment within 10 years.”
Understanding Gabapentin: Uses and Mechanism
Gabapentin is an anti-seizure medication frequently prescribed off-label to manage nerve-related pain, including chronic low back pain and restless leg syndrome. It functions by dampening abnormal electrical activity in the brain’s neurons, which can alleviate neuropathic pain symptoms.
While gabapentin is effective for many patients, prior studies have hinted at a potential link to cognitive decline, prompting the need for more focused research.
Key Findings: Increased Risk Among Chronic Low Back Pain Patients
The study analyzed data from over 26,000 patients diagnosed with chronic low back pain between 2004 and 2024. Patients were grouped based on their gabapentin prescriptions, comparing those with six or more prescriptions to those without any.
- Patients prescribed gabapentin six or more times showed approximately a 30% higher likelihood of developing dementia.
- The risk of mild cognitive impairment was 85% higher in the same group.
- Younger patients (under 65 years old) and those with 12 or more prescriptions exhibited even greater relative risk.
Implications and Next Steps for Research
It is important to note that retrospective observational studies like this demonstrate correlation but cannot definitively establish causation. Nevertheless, the strong association warrants further research to understand whether gabapentin directly contributes to cognitive decline and through what biological mechanisms.
Until more conclusive evidence is available, the study’s authors recommend increased vigilance: physicians should carefully consider the risks when prescribing gabapentin, particularly for long-term use, and monitor cognitive function in patients receiving the drug.
“Our results support the need for close monitoring in adult patients prescribed gabapentin to assess for potential cognitive decline,” the researchers emphasized.
Frequently ASked Questions
What is the medication being linked to dementia risk?
The medication is gabapentin, commonly prescribed for nerve pain, seizures, and conditions like restless leg syndrome and chronic low back pain.
What does the research say about gabapentin and dementia?
A recent study suggests that long-term or frequent use of gabapentin may be associated with a higher risk of dementia or mild cognitive impairment over a 10-year period.
Who conducted the study?
Researchers at Case Western Reserve University led the study, analyzing over 26,000 patient records with chronic low back pain.
Is gabapentin proven to cause dementia?
No. The study shows a correlation, not causation. More research is needed to determine whether gabapentin directly causes dementia.
Should I stop taking gabapentin?
Do not stop any medication without consulting your doctor. If you’re concerned, speak with your healthcare provider to discuss alternatives or cognitive monitoring.
Are there safer alternatives for managing chronic pain?
There are many approaches to pain management—physical therapy, other medications, cognitive behavioral therapy, and lifestyle changes—that may be explored under medical supervision.
Conclusion
Gabapentin remains an important option in pain management, but this new research suggests it may carry risks that clinicians and patients need to weigh carefully. As awareness grows, both healthcare providers and patients should engage in open discussions about the potential cognitive effects of this medication, ensuring informed decision-making in chronic pain treatment plans.
