Power ache impacts over 51 million adults in the US, interfering with day by day operate, psychological well being, and high quality of life.1 As strain mounts to cut back opioid prescribing, various medicine have taken their place. Amongst them, gabapentin has emerged as one of the generally used choices for long-term ache, with almost 70 million prescriptions written every year.2
Although initially developed to deal with epilepsy, gabapentin is now routinely prescribed for a spread of persistent circumstances, notably these thought-about neuropathic. When you’ve been identified with neuropathy, fibromyalgia, or persistent again ache with a nerve element, there’s a superb likelihood your physician has beneficial it.3 However as extra individuals take it, new considerations emerge.
Sufferers and docs alike have reported modifications in reminiscence, focus, and total psychological readability over time, elevating questions concerning the results of gabapentin past ache reduction. Working example, a current research revealed within the journal Regional Anesthesia and Ache Drugs confirmed how this drug, designed to calm overactive nerve indicators, can be dulling psychological sharpness in methods which can be solely beginning to come into focus.4
What Is Gabapentin and How Did It Develop into So Broadly Used?
Gabapentin is a completely artificial pharmaceutical compound, initially developed within the Nineties as an adjunct therapy for partial seizures.5 It belongs to a category of medication known as gabapentinoids, which additionally embrace pregabalin (Lyrica) and mirogabalin.6,7
Although its molecular construction mimics gamma-aminobutyric acid (GABA), the mind’s major calming neurotransmitter, gabapentin acts by means of a unique pathway. Over time, it moved from area of interest neurology drug to a mainstream possibility for persistent ache, a transition formed primarily by aggressive advertising campaigns.
• Gabapentin acts by means of calcium channel modulation — In contrast to GABA, gabapentin doesn’t bind to GABA receptors or improve GABA signaling. As a substitute, it attaches to the alpha-2-delta subunit of voltage-gated calcium channels within the central nervous system. This reduces the discharge of excitatory neurotransmitters like glutamate and norepinephrine, serving to to calm overactive nerve signaling.8
• A serious advertising push helped drive off-label prescribing for unapproved makes use of — As curiosity in gabapentin grew, the drug’s producer, Pfizer, launched an aggressive marketing campaign to advertise past its authorised use. The technique targeted on encouraging physicians to prescribe gabapentin for a variety of unapproved indications, together with migraines, nervousness, bipolar dysfunction, and common persistent ache.
• Regardless of authorized penalties, gabapentin grew to become a staple of persistent ache administration — This advertising push finally led to a federal investigation, uncovering proof that the corporate had illegally promoted the drug for off-label makes use of. The case resulted in a virtually billion-dollar positive (one of many largest on the time), however the observe had already succeeded in embedding gabapentin into mainstream ache administration.
Regardless of restricted proof for a lot of of those makes use of, long-term prescribing has develop into routine. Sufferers are sometimes stored on gabapentin for years with out formal reassessment, and dose changes are hardly ever made even when the advantages are unclear.
• Gabapentin misuse is on the rise — Though usually described as non-addictive, gabapentin is steadily misused, notably in people with a historical past of substance use. It’s usually taken in excessive doses to induce euphoria or sedation, mimicking opioids or benzodiazepines. As much as 22% of individuals with opioid use dysfunction report misusing gabapentin.9

Gabapentin and Dementia Danger in Power Ache Sufferers
The featured research explored whether or not frequent gabapentin use will increase the danger of cognitive decline in adults with persistent low again ache. Utilizing well being information from 2004 to 2024, researchers tracked how usually sufferers have been prescribed gabapentin and whether or not they later developed dementia or gentle cognitive impairment.10
• Over 26,000 adults have been tracked throughout matched teams — Researchers analyzed medical information from adults with persistent low again ache who had no prior historical past of gabapentin use, dementia, epilepsy, stroke, or most cancers. They created two well-matched teams — these prescribed gabapentin and those that weren’t.
They have been then matched by age, gender, different well being circumstances, and use of ache drugs and grouped by what number of prescriptions they obtained, from simply three to a dozen or extra. This design helped isolate gabapentin as the important thing variable, strengthening the reliability of the outcomes.
• Gabapentin use was linked to greater charges of cognitive decline — Sufferers who obtained six or extra prescriptions had a 29% greater threat of creating dementia and an 85% greater threat of gentle cognitive impairment in comparison with those that by no means took gabapentin. These outcomes recommend that frequent gabapentin use contributes to cognitive decline, even in low-risk people.
• Youthful adults confronted the best improve in threat — In sufferers aged 18 to 64, gabapentin customers had greater than double the danger of being identified with dementia and gentle cognitive impairment in comparison with matched controls. These findings increase concern about neurological results in individuals far youthful than the standard age for cognitive issues.
• Extra prescriptions meant higher threat — Sufferers who obtained gabapentin three to 5 instances didn’t present a statistically vital improve in cognitive diagnoses, however these with 12 or extra prescriptions had a 40% greater threat of dementia and a 65% greater threat of gentle cognitive impairment. This means that persistent use, moderately than occasional prescribing, drives the modifications noticed.
• Research limitations mood interpretation, however the development is powerful — As a retrospective research, the findings present affiliation moderately than direct causation. Knowledge on dose, therapy length, and adherence weren’t included, and a few cognitive signs might have emerged earlier than formal analysis.
Nonetheless, the clear dose-response sample and the energy of the associations, particularly in youthful adults, assist the necessity for medical vigilance. The researchers concluded:
“Gabapentin prescription in adults with persistent low again ache is related to elevated threat of dementia and cognitive impairment, notably in non-elderly adults. Physicians ought to monitor cognitive outcomes in sufferers prescribed gabapentin.”11
As off-label use of gabapentin continues to rise, this research provides to considerations that medicine concentrating on nerve indicators can also have an effect on reminiscence, consideration, and mind well being in unintended methods.
Earlier Taiwanese Research Hyperlinks Gabapentinoids to Dementia
Including assist to those current findings, a 2023 retrospective cohort research revealed in Frontiers in Pharmacology examined whether or not long-term use of gabapentin or pregabalin was related to an elevated threat of dementia. The researchers used knowledge from Taiwan’s Nationwide Well being Insurance coverage Analysis Database (NHIRD), specializing in adults who obtained a first-time prescription for one in every of these medicine between 2000 and 2015.12
• Massive-scale knowledge confirmed a forty five% elevated dementia threat — Researchers analyzed 206,802 sufferers, together with 34,467 who had taken gabapentin or pregabalin for not less than 90 days. After adjusting for age, gender, and different well being circumstances, customers have been 45% extra more likely to develop dementia than non-users. The elevated threat held regular throughout each sexes and a variety of comorbidities.
• Youthful adults confronted a disproportionately excessive threat — Amongst sufferers below 50, these taking gabapentin or pregabalin have been greater than 3 times as more likely to develop dementia in comparison with related people who didn’t use the medicine. This discovering raises concern that youthful brains, with greater plasticity and completely different drug processing, are particularly weak to long-term cognitive results.
• Danger elevated with cumulative dose — Just like the Regional Anesthesia and Ache Drugs analysis, this research discovered a transparent dose-response relationship between dementia threat and using gabapentin or pregabalin. These with low cumulative publicity confirmed no vital improve, however high-dose customers had markedly elevated threat.
• Organic mechanisms clarify the cognitive results — As talked about earlier, gabapentin and pregabalin bind to the alpha-2-delta subunit of voltage-gated calcium channels, which disrupts the steadiness between excitatory and inhibitory signaling within the mind.
The research supplied additional insights, highlighting that alpha-2-delta subunits are overexpressed within the hippocampus, the mind’s reminiscence middle, making this area particularly delicate to long-term interference.
These outcomes add vital context to different research linking gabapentin to cognitive decline. The sample is just not restricted to a single nation, drug, or methodology. As a substitute, it is displaying up throughout giant populations and impartial datasets, pointing to a broader, extra constant concern.

Even normal doses might dangerously sluggish inhaling older adults, individuals with lung points, or sufferers on sedating drugs.15
• Physique and coordination points — Lengthy-term use is linked to weight acquire, swelling (peripheral edema), digestive points, and fatigue. Many customers additionally report ataxia, which is a lack of coordination that makes them really feel unsteady or “off steadiness.” These uncomfortable side effects are particularly dangerous for older adults weak to falls or frailty.16
Even when sufferers need to cease taking gabapentinoids, doing so isn’t all the time simple, as they trigger withdrawal signs like nervousness, insomnia, restlessness, and nausea.17 This burden locks sufferers into long-term use, even when the advantages are unclear or absent.
