🧠 Common back-pain drug linked to higher dementia risk, large study finds
A widely used pain medication, gabapentin, commonly prescribed for chronic back pain and nerve-related conditions, has been linked to an increased risk of dementia and cognitive decline, according to a large new study.
📊 What the study found
The research, published in the journal Regional Anesthesia & Pain Medicine, analyzed medical records of more than 50,000 adults with chronic low back pain over a period of up to 10 years. (News-Medical)
Key findings include:
- Patients who received 6 or more prescriptions of gabapentin had:
- 29% higher risk of dementia
- 85% higher risk of mild cognitive impairment (MCI) (News-Medical)
- Those with 12 or more prescriptions had even greater risks:
- 40% higher dementia risk
- 65% higher MCI risk (News-Medical)
- The risk increased with longer or more frequent use, suggesting a possible dose-response relationship. (2 Minute Medicine)
👥 Younger adults showed surprising risk
One of the most unexpected findings was that younger adults (ages 18–64) were more affected:
- They had more than double the risk of developing dementia or MCI compared to those not taking the drug (Drugs.com)
- In some age groups (35–49), dementia risk more than doubled, and cognitive impairment risk more than tripled (Fisher Alzheimer’s Foundation)
This is notable because dementia is usually associated with older age.
💊 Why gabapentin is widely used
Gabapentin is:
- Originally developed to treat epilepsy
- Now widely prescribed for:
- nerve pain
- chronic back pain
It became popular as a safer alternative to opioids, since it has lower addiction potential. (News-Medical)
⚠️ Important: This does NOT prove causation
Experts strongly emphasize that:
- This study shows a link (association) — not proof that gabapentin causes dementia (BMJ Group)
- Other factors may explain the findings, such as:
- Chronic pain itself
- Reduced physical activity
- Other health conditions (Fisher Alzheimer’s Foundation)
Because the study is observational, it cannot establish cause and effect.
🔬 How the study was conducted
- Researchers used a large U.S. health database (TriNetX)
- Compared:
- Patients prescribed gabapentin
- Patients not taking the drug
- Carefully adjusted for:
- Age
- medical conditions
- other medications (News-Medical)
Even after adjustments, the increased risk remained.
🧑⚕️ What experts recommend
Researchers and clinicians say:
- Patients should NOT stop taking gabapentin suddenly
- Doctors should:
- Use the lowest effective dose
- Monitor patients for memory or cognitive changes
- More research is needed to understand:
- Whether the drug directly affects the brain
- Which patients are most at risk (Pharmacy Times)
🧾 Bottom line
- A major study suggests that frequent or long-term use of gabapentin is linked to a higher risk of dementia and cognitive decline
- The risk appears higher in younger adults and with increased use
- However, the findings do not prove the drug causes dementia, and more research is needed
If you want, I can also explain:
- Who should avoid or be careful with this medicine
- Safer alternatives for back pain
- Or whether this risk applies to short-term use
