Here we utilized resting-state functional magnetic resonance imaging (R-fMRI) to measure
the amplitude of low-frequency fluctuations (ALFF) and fractional ALFF (fALFF) in 24 patients …

Background Previous studies have shown that brain functional activity in the resting state is
impaired in Alzheimer's disease (AD) patients. However, alterations in intrinsic brain activity …

Mild cognitive impairment (MCI) refers to a transitional state between normal aging and
dementia and is a syndrome with cognitive decline greater than expected for an individual's …

Patients with amnestic mild cognitive impairment (aMCI) are at an increased risk of further
deterioration and eventually developing Alzheimer's disease (AD). Therefore, the …

Recent resting-state functional magnetic resonance imaging (rs-fMRI) studies have provided
strong evidence of abnormal spontaneous brain activity in amnestic mild cognitive …

The amplitude of low frequency fluctuations (ALFF) from resting-state functional MRI (rs-
fMRI) signals can be used to detect intrinsic spontaneous brain activity and provide valuable …

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 …

Resting-state functional magnetic resonance imaging (RS-fMRI) allowed researchers to
detect intrinsic brain activity during rest and has been considered an analytical tool for …
