Exposure to Antidepressant Medication and the Risk of Incident Dementia

Abstract

Objective To test competing hypotheses that monotherapeutic antidepressant exposure is associated with an increased versus a decreased risk of dementia. Methods A prospective national matched cohort study from Israel (N = 71,515) without dementia (2002-2012) aged 60 and over were followed up for incident dementia from May 2013 to October 2017. Exposure to antidepressant monotherapy was classified with Anatomical Therapeutic Chemical Codes (N06A) from January 1, 2013 to December 31, 2016. The association between antidepressant monotherapy and the risk of incident dementia was quantified with hazard ratios (HR) and their 95% confidence intervals (CI) obtained from Cox regression models unadjusted and adjusted for 42 covariates. The robustness of the results was tested with 24 sensitivity analyses: 19 analyses restricted to subsamples with plausible differential dementia risks (e.g., anxiety and depression), and 5 analyses across and within antidepressant drug classes. Results In the primary analysis, the risk of incident dementia for the group exposed to antidepressant monotherapy compared to the group unexposed to antidepressants was estimated with an unadjusted HR = 4.09 (df = 1, 95% Wald CI = 3.64, 4.60) and an adjusted HR = 3.43 (df = 1, 95% Wald CI = 3.04, 3.88). Across the 24 sensitivity analyses the estimated adjusted HR values ranged from 1.99 to 5.47. Conclusion In this study, monotherapeutic antidepressant exposure in old age was associated with increased incident dementia. Clinicians, caregivers, and patients may wish to consider this potentially negative consequence of antidepressant exposure and aim to balance the costs and benefits of treatment.

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.

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.
