We used resting‐state functional MRI to investigate spatial patterns of spontaneous brain
activity in 22 healthy elderly subjects, as well as 16 mild cognitive impairment (MCI) and 16 …

Purpose: Previous studies have shown that the strength of the low frequency fluctuation in
the medial-line brain areas are abnormally reduced in mild cognitive impairment (MCI) and …

We used resting-state functional magnetic resonance imaging to measure the amplitude of
low-frequency fluctuations (ALFF) of intrinsic brain activity in 23 patients with moderate …

We used resting-state functional magnetic resonance imaging (fMRI) to investigate changes
in the thalamus functional connectivity in early and late stages of amnestic mild cognitive …

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) …

Using resting-state functional magnetic resonance imaging, spontaneous low-frequency
fluctuations in the blood oxygenation level-dependent signal were measured to investigate …

Alzheimer's disease (AD), the most prevalent cause of dementia in the elderly, is
characterized by progressive cognitive and intellectual deficits. Most patients with mild …

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 …

Alzheimer's disease (AD) is associated with disruptions in brain activity and networks.
However, there is substantial inconsistency among studies that have investigated functional …

Functional MRI (fMRI) studies of mild cognitive impairment (MCI) and Alzheimer's disease
(AD) have begun to reveal abnormalities in large-scale memory and cognitive brain …
