The consequences of antipsychotic medication use for people living with dementia: a systematic review and meta-analysis.
Synthesis in Frontiers in psychiatry, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Antipsychotic drugs (APD) are commonly prescribed to people living with dementia (PwD) to manage behavioral and psychological symptoms of dementia (BPSD), despite well-documented safety concerns. International guidelines recommend non-pharmacological interventions as first-line treatment, yet APDs remain widely used. This systematic review and meta-analysis synthesize current evidence on the consequences of APD use in PwD. Following PRISMA guidelines, we conducted a comprehensive search of PubMed, EMBASE, Cochrane Library, and Web of Science for studies published between January 2010 and August 2024. The protocol was registered in PROSPERO on 25 March 2022 (CRD42022312570). Eligible studies included observational and interventional designs reporting APD use in PwD. Risk of bias was assessed using the Cochrane tool for randomized trials and the Newcastle-Ottawa Scale for observational studies. Hazard ratios (HRs) were pooled using a random-effects meta-analysis. Subgroup analyses were performed by APD type (typical vs. atypical), study design, risk of bias, and patient setting. The certainty of the evidence was evaluated using GRADE. Forty-five studies comprising two million participants were included. Twenty-five studies reported mortality outcomes. Meta-analysis showed APD use was associated with a significantly increased mortality risk (pooled HR = 1.32; 95% CI 1.12, 1.56), with considerable heterogeneity (I2 = 98.86%). Subgroup analysis indicated similar risk elevation for both typical and atypical APDs and higher hazards among community-dwelling individuals. Evidence for other adverse outcomes, such as stroke, pneumonia, hip fractures, and hospitalization, was limited and heterogeneous, though several individual studies indicated elevated risks. Meta-analysis of cerebrovascular events showed an attenuated but non-significant association (pooled HR = 1.77; 95% CI 0.92-3.42). Conclusion: APD use in PwD is consistently associated with increased mortality and may even elevate risks for serious non-fatal events. These findings emphasize the necessity of cautious prescribing, regular medication review and close monitoring for PWD. Future research can explore drug-specific effects, dose-response relationships, and long-term outcomes, particularly in low-resource settings.
