Journal ArticleDOI
Loss of 'small-world' networks in Alzheimer's disease: graph analysis of FMRI resting-state functional connectivity.

TL;DR: Evidence is presented of AD-induced changes in global brain functional connectivity specifically affecting long-distance connectivity, which supports the anterior-posterior disconnection theory and its role in AD.
Journal ArticleDOI
Resting-state fMRI changes in Alzheimer's disease and mild cognitive impairment.
Maja Binnewijzend,Menno M. Schoonheim,Ernesto J. Sanz-Arigita,Alle Meije Wink,Wiesje M. van der Flier,Nelleke Tolboom,Sofie Adriaanse,Jessica S. Damoiseaux,Philip Scheltens,Bart N.M. van Berckel,Frederik Barkhof +10 more
TL;DR: Clinical relevant decreased FC within the default-mode network (DMN) in the precuneus and posterior cingulate cortex compared with controls was observed in Alzheimer's disease.
Journal ArticleDOI

TL;DR: It is found that even a mild sleep disruption that suppressed slow-wave activity and induced shallow sleep, but did not reduce total sleep time, was sufficient to affect subsequent successful encoding-related hippocampal activation and memory performance in healthy human subjects.
Journal ArticleDOI
White matter tract integrity in aging and Alzheimer's disease.
Jessica S. Damoiseaux,Stephen M. Smith,Menno P. Witter,Ernesto J. Sanz-Arigita,Frederik Barkhof,Philip Scheltens,Cornelis J. Stam,Mojtaba Zarei,Serge A.R.B. Rombouts,Serge A.R.B. Rombouts +9 more
TL;DR: The results show that changes in WM integrity are different between healthy aging and AD: in healthy older subjects compared with healthy young subjects decreased FA was primarily observed in frontal, parietal, and subcortical areas whereas in AD, compared withhealthy older subjects, decreasedFA was only observed in the left anterior temporal lobe.
Journal ArticleDOI
Resting state networks change in clinically isolated syndrome.

TL;DR: These changes are lost in patients with relapsing remitting multiple sclerosis with increasing brain damage, indicating that cortical reorganization of resting state networks is an early and finite phenomenon in multiple sclerosis.
