ACE and Alzheimer disease: The ADRAP subject score did not show any significant correlation with ACE-R in AD (r = −0.04, p = 0.8) in contrast to ADRTP (Figure 4D), confirming previous reports (Fripp et al., 2008) and supporting the view that PiB deposition is not independently correlated to the development of dementia (Rowe et al., 2007; Jack et al., 2009; Canter et al., 2016).
