Rethinking antipsychotic use in dementia: a literature review on efficacy, safety, and alternatives

Abstract

Background an objectives. Dementia and its associated behavioral and psychological symptoms (BPSD) significantly impact patients’ quality of life, healthcare systems, and caregivers. Current treatments often include antipsychotic medications; however, their efficacy and safety profiles require careful evaluation. This review aimed to examine the use of antipsychotics in dementia, focusing on their role, efficacy, adverse effects, and clinical monitoring guidelines. Materials and methods. We conducted a thorough literature review in PubMed and Medline databases, using search terms like “dementia”, “BPSD”, “antipsychotics”, “adverse effects”, and “clinical guidelines”. Our analysis encompassed a range of research studies, including meta-analyses, randomized controlled trials, observational studies, and clinical practice guidelines. Results. While antipsychotics can be effective in managing severe BPSD symptoms like agitation and psychosis, their use carries an increased risk of mortality, stroke, and other adverse effects. Therefore, strict adherence to clinical guidelines and close monitoring are crucial to minimize these risks. Importantly, nonpharmacological interventions should always be the first-line treatment for BPSD whenever possible. Conclusions. Antipsychotics may be necessary for severe BPSD when nonpharmacological approaches are insufficient. Clinicians must carefully weigh the potential benefits against significant risks, utilizing the lowest effective doses, strict monitoring protocols, and considering alternative pharmacological options when possible. Unveiling safer and more specific BPSD treatments is a critical area for continued research.
