In this study we used resting state f-MRI to investigate
the contribution of White Matter Hyperintensities (WMHs)
in determining functional connectivity (FC) changes in
amnestic Mild Cognitive Impairment patients, the
prodromal stage of Alzheimer disease. WMHs volumes were
quantified by semiautomatic method on TSE images and
used to distinguish patients in two different groups
(high WMHs volume H and low WMHs volume L). The main
finding of the study was that a higher WMHs volume can
determine changes in FC and that these alterations are
associated with the presence of cognitive deficits in
the patients.
