“…Novel findings have been enhancing the understanding of the simultaneous association between personality traits and cognitive status and death, as well as cognitive health span and longevity (Yoneda et al., 2022 ). Personality changes in AD have been highlighted in the literature and may be a potential early clinical indicator (Duberstein et al., 2010 ; Duchek et al., 2007 ; Henriques‐Calado et al., 2016 , 2017 , 2018 ; Pocnet et al., 2011 , 2013 , 2012 ; von Gunten et al., 2009 ; Wahlin & Byrne, 2011 ). Some researchers suggest that the pre‐morbid characteristics of personality may represent a risk factor for AD, and thus, pre‐morbid personality should differ between patients and controls (Balsis et al., 2005 ; Duberstein et al., 2010 ; von Gunten et al., 2009 ).…”
