Abstract

Objective To test the hypothesis that the load of psychotropic agents was associated with subsequent dementia occurrence by a nationwide database. Design Propensity score matched case-control study. Setting National Health Insurance Research database. Participants A total of 32,649 older people with dementia and 32,649 matched dementia-free older people. Measurements Use of psychotropic drugs (anxiolytics, antipsychotics, hypnotics, and antidepressants), defined daily dose (DDD) of psychotropic drugs, diagnosis of dementia, and propensity score. Intervention None. Results Compared with nonusers, ever use of psychotropic agents was associated with higher odds of subsequent dementia [adjusted odds ratio (OR): 3.73; 95% confidence interval (CI) (3.59-3.88)]. Significantly, the association was stronger with longer term exposure to psychotropic agents. The ORs at exposures of 180 days, were 3.14 (95% CI 3.01-3.28); 5.48 (5.07-5.93); and 7.54 (6.73-8.44), respectively. A similar and stronger association was identified when cumulative dose was used to measure the exposure of psychotropic agents [ 180 DDDs, 7.35 (6.29-8.58)]. Conclusions We found that a higher burden of psychotropic agents was strongly associated with a higher odds of subsequent dementia. Careful monitoring of any elderly who is prescribed or uptitrated psychotropic agents is highly recommended, especially those who combine use of more than one agent. Furthermore, providing timely assessment for cognitive function fo…

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.
