The study showed that amnestic mild cognitive impairment
(aMCI) had the deficits of gray matter (GM) volume on
the network of cerebellum-limbic system, and suggests an
apolipoprotein E (APOE)-specific effect of age with GM
volume on the occipito-insula-frontal neural circuit.
Moreover, the results suggest that GM deficits could be
accelerated by the combined effect of the aging process
and the presence of the APOE 4 allele. Conversely, the
APOE 2 possibly reflects a protective morphometric
main effect, which increases with age in aMCI. The
relationship of GM alterations with neuropsychological
test supported that GM atrophy was the basis of
cognitive impairment in aMCI.
