The pathophysiol.gical.and behavioural.features of Al.heimer’s disease (AD) have been extensivel. investigated in transgenic mouse model., incl.ding the temporal.sequence of each pathophysiol.gical.change and behavioural.abnormal.ty, a summary of which was recentl. presented by our team in this Journal.(l. et al.,2023). Neverthel.ss, studying such features and timings directl. in human patients before symptoms occur is chal.enging. Starting from famil.al.AD, then gradual.y shifting to sporadic AD, growing evidence from l.ngitudinal.studies indicates that biomarkers change at l.ast10 to 20 years before the onset of symptoms in AD (Bateman et al., 2012;Vil.emagne et al., 2013; Gordon et al.,2018; Vermunt et al., 2019).
