“…On the one hand, several reports of impaired familiarity in MCI and AD patients (Algarabel et al, 2009; Ally, Gold, & Budson, 2009; Didic et al, 2013; Embree, Budson, & Ally, 2012; Wolk et al, 2013; Wolk et al, 2008) are consistent with the prediction that item familiarity should be disrupted very early in the course of Alzheimer's disease due to initial deterioration of the extrahippocampal medial temporal lobe regions on which it depends (Didic et al, 2011). On the other hand, there is contrasting evidence of spared familiarity in MCI and AD, notably in memory tasks for pictures (Embree et al, 2012; O'Connor & Ally, 2010; Westerberg et al, 2013; Westerberg et al, 2006), but also in verbal memory tasks (Anderson et al, 2008; Belleville, Menard, & Lepage, 2011; Genon et al, 2013, 2014; Serra et al, 2010). …”
