An analysis of 126 amyloid-negative adults aged 30 to 89 years with PET and a cognitive battery at baseline and at 4-year follow-up showed a relationship between specific regional accumulation of amyloid in posterior cortical regions and declining episodic memory.
The authors pointed out that assessing regional changes in amyloid accumulation may indeed be a marker for detecting subclinical amyloid related decline. As always, more research is needed.
