Deans' stroke musings: Common Pain Medication Linked to Cognitive Decline Risk

Changing stroke rehab and research worldwide now.Time is Brain! trillions and trillions of neurons that DIE each day because there are NO effective hyperacute therapies besides tPA(only 12% effective). I have 523 posts on hyperacute therapy, enough for researchers to spend decades proving them out. These are my personal ideas and blog on stroke rehabilitation and stroke research. Do not attempt any of these without checking with your medical provider. Unless you join me in agitating, when you need these therapies they won't be there.

What this blog is for:

My blog is not to help survivors recover, it is to have the 10 million yearly stroke survivors light fires underneath their doctors, stroke hospitals and stroke researchers to get stroke solved. 100% recovery. The stroke medical world is completely failing at that goal, they don't even have it as a goal. Shortly after getting out of the hospital and getting NO information on the process or protocols of stroke rehabilitation and recovery I started searching on the internet and found that no other survivor received useful information. This is an attempt to cover all stroke rehabilitation information that should be readily available to survivors so they can talk with informed knowledge to their medical staff. It lays out what needs to be done to get stroke survivors closer to 100% recovery. It's quite disgusting that this information is not available from every stroke association and doctors group.

Common Pain Medication Linked to Cognitive Decline Risk

Be careful out there.

Common Pain Medication Linked to Cognitive Decline Risk

Summary: A large U.S. medical records study has found that adults prescribed gabapentin six or more times for chronic low back pain face significantly higher risks of dementia (29%) and mild cognitive impairment (85%) within 10 years. The risks were especially pronounced in younger adults aged 35–64, where rates of cognitive decline more than doubled or tripled compared to those not on the drug.

The findings suggest a dose-response relationship, with more frequent prescriptions correlating with higher risks. While observational and not proof of causation, the study underscores the need to monitor patients on long-term gabapentin for signs of cognitive decline.

Key facts:

Adults prescribed gabapentin ≥6 times were 29% more likely to develop dementia and 85% more likely to develop mild cognitive impairment.
Risks were more than doubled in 35–64 year olds compared to unprescribed peers.
The more prescriptions filled, the higher the risk of cognitive decline.

Receiving six or more prescriptions of the drug gabapentin for low back pain is associated with significantly increased risks of developing dementia and mild cognitive impairment (MCI)–29% and 85%, respectively—finds a large medical records study published online in the journal Regional Anesthesia & Pain Medicine.

What’s more, these risks were more than twice as high in those normally considered too young to develop either condition—18-64 year olds—the findings indicate.

Unlike opioids, gabapentin has relatively low addictive potential, and it has become increasingly popular for the treatment of chronic pain, especially neuropathic pain, as it offers potentially neuroprotective benefits, point out the researchers.

But concerns are beginning to emerge about its side effects, including a possible association with neurodegeneration, although the findings to date have been mixed, including if particular age groups might be more vulnerable they add.

In a bid to shed more light on these issues, the researchers drew on real-time data from TriNetX, a federated health research network, which contains electronic health records from 68 healthcare organisations across the USA.

They scrutinised the anonymised records of adult patients who had and hadn’t been prescribed gabapentin (26,414 in each group) for chronic low pain between 2004 and 2024, taking account of demographics, co-existing conditions, and the use of other analgesic drugs.

Those who had received six or more gabapentin prescriptions were 29% more likely to be diagnosed with dementia and 85% more likely to be diagnosed with MCI within 10 years of their initial pain diagnosis.

And when the records were stratified by age, 18–64 year olds prescribed the drug were more than twice as likely to develop either condition than those who hadn’t been prescribed gabapentin.

While there was no heightened risk among 18–34 year olds prescribed the drug, the risks of dementia more than doubled and those of MCI more than tripled among 35–49 year olds prescribed it. A similar pattern was observed among 50–64 year olds.

Risks also rose in tandem with prescription frequency: patients with 12 or more prescriptions were 40% more likely to develop dementia and 65% more likely to develop MCI than those prescribed gabapentin between 3 and 11 times.

This is an observational study, and as such, no firm conclusions can be drawn about cause and effect. The researchers also acknowledge that their study was retrospective, and they weren’t able to account for dose or length of gabapentin use.

Nevertheless, they conclude: “Our findings indicate an association between gabapentin prescription and dementia or cognitive impairment within 10 years. Moreover, increased gabapentin prescription frequency correlated with dementia incidence.”

They add: “Our results support the need for close monitoring of adult patients prescribed gabapentin to assess for potential cognitive decline.”
