In the past decade, a “default mode network”(DMN) has been highlighted in neuroimaging
studies as a set of brain regions showing increased activity in task‐free state compared to …

We applied a multi-modal imaging approach to examine structural and functional alterations
in the default-mode network (DMN) that are associated with Alzheimer's disease (AD) and …

Although in the last decade brain activation in healthy aging and dementia was mainly
studied using task-activation fMRI, there is increasing interest in task-induced decreases in …

A prominent finding of postmortem and molecular imaging studies on Alzheimer's disease
(AD) is the accumulation of neuropathological proteins in brain regions of the default mode …

Alzheimer's disease (AD) is the most common form of dementia in old age, and is
characterized by prominent impairment of episodic memory. Recent functional imaging …

BACKGROUND: Important functional connections within the default mode network (DMN)
are disrupted in Alzheimer's disease (AD), likely from amyloid-beta (Aβ) plaque-associated …

Objective: To investigate age-related default mode network (DMN) connectivity in a large
cognitively normal elderly cohort and in patients with Alzheimer disease (AD) compared with …

Recent functional imaging studies have revealed coactivation in a distributed network of
cortical regions that characterizes the resting state, or default mode, of the human brain …

Neurodegenerative brain changes can affect the functional connectivity strength between
nodes of the default-mode network (DMN), which may underlie changes in cognitive …

Amnestic mild cognitive impairment (aMCI) is believed to represent a transitional stage
between normal healthy ageing and the development of dementia. In particular, aMCI …
