“…Although there are nine studies did not find any relationship between demographic characteristics and QoL (Andersen et al, 2004;Grske et al, 2014;Moyle et al, 2015;Monteiro et al, 2014;Sloane et al, 2005;Winzelberg et al, 2005;Wetzels et al, 2010;Salvador et al, 2000), other studies found that higher education (Marventano et al, 2015;Li et al, 2012), males (Woods et al, 2014;Barca et al 2011), white (Black et al, 2012), widowed (Samus et al, 2005) and extroverted characteristic (Li et al, 2012) tended to be positively associated with better QoL for elderly people with dementia. Moreover, Banerjee et al (2005) found that QoL of people with dementia showed decline as with the increasing age, while Mjørud et al (2014) indicated that the QoL was worse among the youngest (<79) and oldest (>90) people with dementia.…”
