Complementary and alternative medicines for behavioral and psychological symptoms of dementia: A protocol of overview of systematic reviews

BACKGROUND: Dementia is causing a huge medical and socioeconomic burden. Along with strategies to delay cognitive decline in dementia, behavioral and psychological symptoms of dementia (BPSD) are major contributing factor to the burden of dementia, and have been an important clinical issue for successful management of dementia. However, pharmacological strategies such as antipsychotics raise concerns in terms of risk-to-benefit ratio in managing BPSD. Therefore, there is a need for an effective and safe alternative in BPSD management. From this point of view, various complementary and alternative medicines (CAMs) are attracting attention in BPSD management. Therefore, the overview will make it possible to evaluate the feasibility of using CAM as a potential treatment strategy for BPSD in terms of evidence-based medicine. METHODS AND ANALYSIS: Comprehensive searching will be performed in 13 bibliographic databases from their inception dates to November 2021. Systematic reviews and/or meta-analyses that examined the effectiveness and safety of CAM modalities including herbal medicine, acupuncture, acupressure, aromatherapy, meditation, and relaxation on BPSD, will be included. The methodological quality of included reviews will be assessed by using the A MeaSurement Tool to Assess systematic Reviews-2. Two independent researchers will conduct study search, study selection, data extraction, and quality assessment processes. RESULTS: The results of overview will be disseminated by the publication of a manuscript in a peer-reviewed journal or presentation at a relevant conference. CONCLUSION: The findings of this overview will help to solve the major public health problem related to dementia, and will provide patients with dementia, their caregivers, clinicians, and health policy makers credible evidence in mitigating the burden of dementia. ETHICS AND DISSEMINATION: As this protocol is for an overview of systematic reviews and meta-analyses, ethical approval is not required.
