Previous studies have led to the proposal that patients with Alzheimer's disease (AD) may
have disturbed functional connectivity between different brain regions. Furthermore, recent …

A selective distribution of Alzheimer's disease (AD) pathological lesions in specific cortical
layers isolates the hippocampus from the rest of the brain. However, functional connectivity …

Background Local network connectivity disruptions in Alzheimer's disease patients have
been found using graph analysis in BOLD fMRI. Other studies using MEG and cortical …

Recent functional imaging studies have indicated that the pathophysiology of Alzheimer's
disease (AD) can be associated with the changes in spontaneous low-frequency (< 0.08 Hz) …

Purpose To investigate alterations in functional connectivity in the resting brain networks in
healthy elderly volunteers and patients with mild, moderate, or severe Alzheimer Disease …

Alzheimer's disease (AD) is increasingly recognized as a disconnection syndrome, which
leads to cognitive impairment due to the disruption of functional activity across large …

Clinical symptoms observed in Alzheimer's disease (AD) patients may reflect variations
within specific large-scale brain networks, modeling AD as a disconnection syndrome. The …

Objectives: The current study evaluated whether the functional connectivity pattern of the
thalamo-cortical network in patients with Alzheimer's disease (AD) and mild cognitive …

Aims Alzheimer's disease (AD) is a progressive neurodegenerative disorder. Previous
studies have demonstrated abnormalities in functional connectivity (FC) of AD under the …

There has been a dramatic increase in the number of studies using resting state functional
magnetic resonance imaging (rs-fMRI), a recent addition to imaging analysis techniques …
