Antidepressant use in relation to dementia risk, cognitive decline, and brain atrophy
Open accessAbstract
INTRODUCTION: We aimed to assess the effect of antidepressant use on dementia risk, cognitive decline, and brain atrophy. METHODS: In this prospective cohort study, we included 5511 dementia‐free participants (Mini‐Mental State Examination [MMSE] > 25) of the Rotterdam study (57.5% women, mean age 70.6 years). Antidepressant use was extracted from pharmacy records from 1991 until baseline (2002–2008). Incident dementia was monitored from baseline until 2018, with repeated cognitive assessment and magnetic resonance imaging (MRI) every 4 years. RESULTS: Compared to never use, any antidepressant use was not associated with dementia risk (hazard ratio [HR] 1.14, 95% confidence interval [CI] 0.92–1.41), or with accelerated cognitive decline or atrophy of white and gray matter. Compared to never use, dementia risk was somewhat higher with tricyclic antidepressants (HR 1.36, 95% CI 1.01–1.83) than with selective serotonin reuptake inhibitors (HR 1.12, 95% CI 0.81–1.54), but without dose–response relationships, accelerated cognitive decline, or atrophy in either group. DISCUSSION: Antidepressant medication in adults without indication of cognitive impairment was not consistently associated with long‐term adverse cognitive effects. Highlights: Antidepressant medications are frequently prescribed, especially among older adults. In this study, antidepressant use was not associated with long‐term dementia risk. Antidepressant use was not associated with cognitive decline or brain atrophy. Our results support safe prescription in an older, cognitively healthy population.

TL;DR
In a prospective Rotterdam Study cohort of 5511 dementia-free older adults, antidepressant use was not consistently associated with long-term dementia risk, cognitive decline, or brain atrophy. Tricyclic antidepressant use showed a modest dementia risk association, but without dose-response or corroborating cognitive, imaging, or instrumental-variable evidence.
Key findings
- Among 5511 participants (57.5% women, mean age 70.6 years), 923 (16.7%) had ever used antidepressants; 639 (11.6%) developed dementia over mean 10.2 years. Any antidepressant use versus never use was not significantly associated with dementia risk (HR 1.14, 95% CI 0.92–1.41), with no dose-response relationship.
- Tricyclic antidepressant use was associated with higher dementia risk (HR 1.36, 95% CI 1.01–1.83), while SSRI use was not (HR 1.12, 95% CI 0.81–1.54); neither showed dose-response relationships. Current use HR was 1.38 (95% CI 0.99–1.93) and past use HR was 1.05 (95% CI 0.82–1.34).
- Antidepressant use was not associated with global cognitive decline (mean difference in g-factor per year β 0.003, 95% CI −0.003 to 0.010) or with change in total brain, gray matter, white matter, hippocampus, amygdala, or thalamus volumes.
- In instrumental variable analyses using CYP2D6 genotype among amitriptyline and paroxetine users, higher risk score was not associated with increased dementia risk (amitriptyline HR 0.90, 95% CI 0.80–1.01; paroxetine HR 0.94, 95% CI 0.81–1.09).
Methods
- Prospective population-based cohort study within the Rotterdam Study; included 5511 dementia-free participants (MMSE >25) aged ≥60 years at baseline (2002–2008), with pharmacy records from 1991 onward, incident dementia follow-up until 2018, and repeated cognitive assessment and MRI every 4 years.
- Exposure was any antidepressant prescription between pharmacy record inception and baseline; analyses compared ever versus never use, former versus current use, duration, cumulative defined daily dose, and tricyclic antidepressants versus SSRIs. Outcomes were all-cause dementia (Cox models), global cognition (linear mixed models), brain volumes (linear mixed models), and instrumental variable analysis using a CYP2D6 genetic risk score.
- Models adjusted for age, sex, and education (Model 1), and additionally for smoking, alcohol, BMI, eGFR, CES-D score, benzodiazepine and antipsychotic use, and comorbidities (Model 2); missing covariates were imputed.
Limitations
- Stated: exclusion of participants with MMSE <26 at baseline may introduce selection bias by disregarding pre-baseline antidepressant effects and excluding lower-educated participants.
- Stated: attrition for repeated cognitive assessment and MRI was 27% and 35%, respectively, potentially attenuating associations; the CYP2D6 genetic risk score could not include gene deletions or duplications, possibly causing misclassification; and results in a predominantly White population may not generalize to non-White populations.
- Evident from text: the observational cohort design cannot fully exclude residual confounding or reverse causation, although the authors attempted to mitigate these via exclusion, stratification, and instrumental variable analysis.

The Abstract describes a growing number of studies on the cognitive effects of antidepressants and cites several that examined cognitive decline. It says few studies examined the effects of *different classes* of antidepressants, a narrower gap than the citing sentence describes. The source therefore supports limited research on that specific question, but not the unqualified claim that few studies examined antidepressant use and cognitive decline. (LLM, conf=0.78)

The Introduction says antidepressant trials involving older adults often last only weeks or months, and that little is known about long-term outcomes of use in elderly people with intact cognition. This supports the concern about short trials, but the cited paper frames the uncertainty around older adults and dementia risk, rather than long-term adverse outcomes across all antidepressant users.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
A language model drew the claims from the paper on 2026-11-07, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-11-07 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
Cited sources are checked with a language model’s help (gpt-6-sol).
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
