Amplitude of low frequency fluctuations (ALFF) of spontaneous and induced rumination in major depression: An fNIRS study [PDF]

Scientific Reports, 2020
AbstractIn the current study, we investigated the amplitude of low frequency fluctuations (ALFF) at rest and during a rumination induction. Specifically, we explored the differences of cortical blood oxygenation using fNIRS in subjects with Major Depressive Disorder (MDD) and healthy controls (HC). Rumination was assessed as state and trait measure, as

Selective Changes of Resting-State Brain Oscillations in aMCI: An fMRI Study Using ALFF [PDF]

BioMed Research International, 2014
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 age and educational level. As a subtype of MCI, amnestic mild cognitive impairment (aMCI) most often leads to Alzheimer’s disease.

Efficacy and Mechanism of Moxibustion Treatment on Mild Cognitive Impairment Patients: An fMRI Study Using ALFF

Frontiers in Molecular Neuroscience, 2022
BackgroundMild Cognitive Impairment (MCI), as a high risk of Alzheimer’s disease (AD), represents a state of cognitive function between normal aging and dementia. Moxibustion may effectively delay the progression of AD, while there is a lack of studies on the treatments in MCI.

Association of Left Angular Gyrus-Right Middle Frontal Gyrus Functional Connectivity With Insomnia Severity in Major Depressive Disorder: Evidence From the DIRECT Consortium. [PDF]

CNS Neurosci Ther
Preferential alterations in insomnia‐related AG–MFG connectivity in MDD highlight sleep‐associated neural mechanisms, although disentangling these connectivity changes from depression severity remains challenging. Local aberrations in regional brain function primarily differentiate patients with MDD from healthy controls.

Aggregation of Vascular Risk Factors Modulates the Amplitude of Low-Frequency Fluctuation in Mild Cognitive Impairment Patients

Frontiers in Aging Neuroscience, 2020
Background: Several vascular risk factors, including hypertension, diabetes, body mass index, and smoking status are found to be associated with cognitive decline and the risk of Alzheimer's disease (AD). We aimed to investigate whether an aggregation of
