“…The aetiology of getting lost is unclear, although it is likely to emanate from dementia-related changes, psycho-social, and environmental factors (Lai & Arthur, 2003). Getting lost may in part reflect spatial disorientation, reduced topographical memory, reduced visualperceptual ability, including object recognition and executive dysfunction (Algase et al, 2004; Algase, Moore, Vandeweerd, & Gavin-Dreschnack, 2007;Chiu, Algase, Liang, Liu, & Lin, 2005;McShane et al, 1998;Nagata et al, 2010;Swanberg, Tractenberg, Mohs, Thal, & Cummings, 2004;Tetewsky & Duffy, 1999). Psycho-social factors that increase walking activity may include personality responses to environmental stressors as well as continuity with pre-morbid active and outdoor lifestyles (Algase, Kupferschmid, Beel-Bates, & Beattie, 1997;Dewing, 2005;Lai & Arthur, 2003;Song & Algase, 2008).…”
