“…Two systematic reviews of systematic reviews (Abraha et al, 2017;Vilela, Pacheco, Latorraca, Pachito, & Riera, 2017) reveal that non-pharmacological interventions have positive effects on reducing BPSD, improving cognitive function, activities of daily living, and social interaction ability of patients with dementia. For apathy, there are several systematic reviews and meta-analyses (Brodaty & Burns, 2012;Fukushima et al, 2016;Goris, Ansel, & Schutte, 2016;Lane-Brown & Tate, 2009;Theleritis, Siarkos, Katirtzoglou, & Politis, 2016;Theleritis, Siarkos, Politis, Katirtzoglou, & Politis, 2018;Tsoi et al, 2018;Verkaik, Weert, & Francke, 2005;Zafra-Tanaka, Pacheco-Barrios, Tellez, & Taype-Rondan, 2019) of non-pharmacological interventions in patients with dementia. Nevertheless, these reviews involve diversified non-pharmacological interventions and lack evaluation of methodological quality and classification of evidence quality.…”
