Persistent ache impacts over 51 million adults in america, interfering with every day operate, psychological well being, and high quality of life.1 As stress mounts to scale back opioid prescribing, different medication have taken their place. Amongst them, gabapentin has emerged as probably the most generally used choices for long-term ache, with practically 70 million prescriptions written every year.2
Although initially developed to deal with epilepsy, gabapentin is now routinely prescribed for a variety of persistent situations, significantly these thought-about neuropathic. Should you’ve been identified with neuropathy, fibromyalgia, or persistent again ache with a nerve part, there’s a superb likelihood your physician has really helpful it.3 However as extra individuals take it, new considerations emerge.
Sufferers and docs alike have reported adjustments in reminiscence, focus, and total psychological readability over time, elevating questions in regards to the results of gabapentin past ache reduction. Working example, a latest 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 are solely beginning to come into focus.4
What Is Gabapentin and How Did It Change into So Extensively Used?
Gabapentin is a totally 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 a distinct 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 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 put it on the market past its authorized use. The technique targeted on encouraging physicians to prescribe gabapentin for a variety of unapproved indications, together with migraines, anxiousness, bipolar dysfunction, and basic persistent ache.
• Regardless of authorized penalties, gabapentin grew to become a staple of persistent ache administration — This advertising push ultimately 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 high quality (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 grow to be 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 typically described as non-addictive, gabapentin is regularly misused, significantly in people with a historical past of substance use. It’s typically 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

• Over 26,000 adults have been tracked throughout matched teams — Researchers analyzed medical data 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 situations, and use of ache drugs and grouped by what number of prescriptions they acquired, 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 acquired six or extra prescriptions had a 29% greater danger of creating dementia and an 85% greater danger of delicate cognitive impairment in comparison with those that by no means took gabapentin. These outcomes counsel that frequent gabapentin use contributes to cognitive decline, even in low-risk people.
• Youthful adults confronted the best enhance in danger — In sufferers aged 18 to 64, gabapentin customers had greater than double the chance of being identified with dementia and delicate cognitive impairment in comparison with matched controls. These findings elevate concern about neurological results in individuals far youthful than the standard age for cognitive problems.
• Extra prescriptions meant better danger — Sufferers who acquired gabapentin three to 5 occasions didn’t present a statistically vital enhance in cognitive diagnoses, however these with 12 or extra prescriptions had a 40% greater danger of dementia and a 65% greater danger of delicate cognitive impairment. This implies that persistent use, reasonably than occasional prescribing, drives the adjustments noticed.
• Examine limitations mood interpretation, however the pattern is powerful — As a retrospective research, the findings present affiliation reasonably than direct causation. Information on dose, therapy period, and adherence weren’t included, and a few cognitive signs could 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 danger of dementia and cognitive impairment, significantly 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 medication concentrating on nerve indicators may have an effect on reminiscence, consideration, and mind well being in unintended methods.
Earlier Taiwanese Examine Hyperlinks Gabapentinoids to Dementia
Including assist to those latest 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 danger of dementia. The researchers used information from Taiwan’s Nationwide Well being Insurance coverage Analysis Database (NHIRD), specializing in adults who acquired a first-time prescription for one in all these medication between 2000 and 2015.12
• Massive-scale information confirmed a forty five% elevated dementia danger — Researchers analyzed 206,802 sufferers, together with 34,467 who had taken gabapentin or pregabalin for at the very least 90 days. After adjusting for age, gender, and different well being situations, customers have been 45% extra more likely to develop dementia than non-users. The elevated danger held regular throughout each sexes and a variety of comorbidities.
• Youthful adults confronted a disproportionately excessive danger — 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 medication. This discovering raises concern that youthful brains, with greater plasticity and totally different drug processing, are particularly susceptible to long-term cognitive results.
• Threat elevated with cumulative dose — Much like the Regional Anesthesia and Ache Drugs analysis, this research discovered a transparent dose-response relationship between dementia danger and using gabapentin or pregabalin. These with low cumulative publicity confirmed no vital enhance, however high-dose customers had markedly elevated danger.
• 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 offered 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 necessary context to different research linking gabapentin to cognitive decline. The sample will not be restricted to a single nation, drug, or methodology. As a substitute, it is exhibiting up throughout giant populations and impartial datasets, pointing to a broader, extra constant concern.

Even normal doses could dangerously gradual 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 negative effects are particularly dangerous for older adults susceptible to falls or frailty.16
Even when sufferers wish to cease taking gabapentinoids, doing so isn’t all the time straightforward, as they trigger withdrawal signs like anxiousness, insomnia, restlessness, and nausea.17 This burden locks sufferers into long-term use, even when the advantages are unclear or absent.
