The operationalization of mild cognitive impairment (MCI) led to targeting earlier symptomatic cases of the illness and treatment strategies based less on pathology and more on a chance to halt or slow decline than there would be earlier in the disease.1 With the development of amyloid imaging, MCI due to AD diagnosis was refined, 2 and early - stage AD was extended further to
include preclinical AD, 3 wherein a positive amyloid positron emission tomography (PET) scan or diagnostic low levels of
cerebrospinal fluid β - amyloid (Aβ) indicated the presence of pathology in people who were cognitively normal.
