In this study functional magnetic resonance imaging (fMRI) is used to investigate the
functional brain activation pattern in the preclinical stage of AD (pre-AD) subjects during a …

Purpose To determine whether individuals with subjective cognitive decline (SCD) exhibit
functional and structural brain alterations by using resting-state functional and structural …

Normal aging and to a greater degree degenerative brain diseases such as Alzheimer's
disease (AD), cause changes in the brain's structure and function. Degenerative changes in …

Attention deficits in patients with amnestic mild cognitive impairment (aMCI) and Alzheimer's
disease (AD) have already been previously proposed. However, previous studies lacked …

Purpose To detect changes in brain lateralization in patients with mild cognitive impairment
(MCI) and Alzheimer's disease (AD) using resting-state functional magnetic resonance …

Early-onset Alzheimer's disease (AD) patients present a different clinical profile than late-
onset AD patients. This can be partially explained by cortical atrophy, although brain …

Recent imaging studies have demonstrated functional brain network changes in patients
with Alzheimer's disease (AD). Eigenvector centrality (EC) is a graph analytical measure that …

Most of the previous task functional magnetic resonance imaging (fMRI) studies found
abnormalities in distributed brain regions in mild cognitive impairment (MCI) and Alzheimer's …

Using resting state (RS) functional magnetic resonance imaging (fMRI), the connectivity
patterns of the default mode (DMN), frontoparietal, executive, and salience networks were …

Resting-state functional magnetic resonance imaging (MRI), have revealed coactivation in a
distributed network that characterizes the default-mode in the human brain. However, details …
