abstract = {Objective: To examine the relationship of β-amyloid (Aβ)
deposition to episodic memory in younger (30–49 years),
middle-older (50–69 years), and older adults (70–89
years). We hypothesized that subclinical levels of amyloid
would be linked to memory in adults across the lifespan in a
dose-dependent fashion. Of great interest was whether,
within the younger group, a relationship between amyloid
level and memory performance could be established.Methods: A
total of 147 participants from the Dallas Lifespan Brain
Study, aged 30–89, underwent PET imaging with
18F-florbetapir and cognitive assessment. We assessed the
relationship between age group and amyloid and tested
whether Aβ differentially affected memory performance
across the 3 age groups.Results: We report a significant
association of age to amyloid burden for younger and
middle-older adults (r = 0.57 and 0.28, respectively), but
not for the oldest group, although absolute level of amyloid
increased across the age groups. Importantly, the youngest
group showed a significant decrease in recall (r = −0.47,
p = 0.004) and recognition memory (r = −0.48, p = 0.003)
as a function of increases in Aβ burden, whereas this
relationship was absent in the middle-older and oldest group
(all p > 0.23).Conclusions: These results indicate that
variance in subclinical levels of Aβ in younger adults is
meaningful, and suggest that higher SUVRs relative to one's
peers at a younger age is not entirely benign.},
