Sheng-En Tsai · Institute of Medicine, Chung Shan Medical University; Changhua Christian Hospital · First-listed study author

Finding: The 2024 author abstract reports no substantial increase in dementia risk among the chronic-pain patients studied. This differs from the 2025 population and does not prove all use safe.

Gabapentin prescriptions and dementia in chronic low back pain

Design:
Cohort
Participants:
26,416 adults following matching as reported in the author abstract; no assumed per-arm or doubled count
Finding:
Higher recorded dementia and mild impairment incidence in certain prescription groups.
Main limitation
Retrospective records and selected back-pain population; association is not individual cause. Prescriptions do not confirm dose consumption. Full paper not reviewed.

Gabapentin and dementia in chronic-pain patients

Design:
Case-control
Participants:
Underlying cohort of 201,492 chronic-pain patients aged 50 or older; final matched comparison count not specified in the author abstract
Finding:
No substantial increased dementia risk in the adjusted analysis described by the abstract.
Main limitation
Nested case-control study in a different population; not proof of safety for every person. Underlying cohort is not a verified matched sample count. Full paper not reviewed.

The short answer

What is a change in memory or thinking?
It may mean new trouble with memory or daily tasks. A memory problem alone does not show that you have dementia or that a drug caused it. [10]
Which symptoms should I tell a doctor about?
Tell the doctor about new memory trouble or slow thinking. Get urgent help for slow breathing, extreme sleepiness or being hard to wake. [3]
How are memory changes diagnosed and treated?
A clinician checks your history and may use tests to look for the cause. Treatment depends on what the assessment finds. [10]
What does the research say about gabapentin?
Two studies of health records found different results. Neither shows what caused one person’s memory problem. [1]

The process

What happens next

  1. 01

    You answer a few questions

    About two minutes. Nothing is sent until you agree on the last step and press submit.

  2. 02

    A lawyer looks at it

    A lawyer at the firm reads your answers and checks them against the current case criteria.

  3. 03

    The firm decides and gets in touch

    If the firm takes your case, you get the terms in writing to read before you sign. You can always say no.

When it fits this case

  • Identify the actual medicine and the dates in your pharmacy records.
  • Describe the diagnosis or symptoms actually recorded by your health team.
  • Ask what evidence would link the medicine to your condition.
  • Ask which law, time limits and prior agreements matter.

What is a change in memory or thinking?

It may mean new trouble with memory or daily tasks. A memory problem alone does not show that you have dementia or that a drug caused it.

Which symptoms should I tell a doctor about?

Tell the doctor about new memory trouble or slow thinking. Get urgent help for slow breathing, extreme sleepiness or being hard to wake.

The FDA warning concerns breathing risks with gabapentin and similar drugs, especially with certain other medicines or lung problems. That emergency warning is separate from a long-term memory diagnosis.

How are memory changes diagnosed and treated?

A clinician checks your history and may use tests to look for the cause. Treatment depends on what the assessment finds.

Bring a full medicine list and notes about when the change began. The memory guide describes several possible causes. Ask what the findings mean before assuming the symptom is dementia or choosing a new treatment.

What does the research say about gabapentin?

Two studies of health records found different results. Neither shows what caused one person’s memory problem.

The 2025 back-pain study reported more dementia diagnoses in some prescription groups. Its abstract reports 26,416 adults after matching. A prescription record does not prove how much medicine was actually taken.

A 2024 study in Taiwan found no substantial rise in dementia risk in the adjusted analysis. It used a different chronic-pain population and study design. Neither result is a personal diagnosis or a rule that everyone is safe.

Who may have a claim to check?

Ask a lawyer to check the harm and drug use. A symptom or count of prescriptions alone does not decide a claim.

A civil case alleges harm and a connection to the party sued. Give the lawyer the facts you know, including earlier memory changes and other medicines. Ask which law and time limit apply rather than assuming a national filing rule.

What health and drug records should I keep?

Keep care notes, test results and prescription dates. Ask the provider how to request missing records and who may receive them.

Separate a clinician's diagnosis from your own concern about the cause. Mark uncertain dates rather than filling gaps from a headline. Health-record access has exceptions; a request does not give every helper unrestricted access.

Find out where you stand.

The review is free and private. Asking for it doesn’t commit you to anything.
