“…The noisy and fast-paced atmosphere of acute hospitals, and particularly emergency departments, can be very disorienting for people living with dementia (Borbasi, Jones, Lockwood, & Emden, 2006;Cowdell, 2010;Cunningham, 2006; Dementia Services Development Centre (DSDC), 2012; Hung et al, 2017;Nolan, 2007;Timmons et al, 2016;Waller & Masterson, 2015). Very often, time spent in an ED can result in responsive behaviours (Brush, Sanford, Fleder, Bruce, & Calkins, 2011;Cunningham, 2006). Stimuli in the environment which others, such as staff, may perceive as acceptable, can reduce the person living with dementia's capacity to cope with the care environment and the severity of cognitive impairment may appear greater (Dewing, 2009).…”
