Dynamic Altered Amplitude of Low-Frequency Fluctuations in Patients With Major Depressive Disorder [PDF]

Frontiers in Psychiatry, 2021
Background: Major depressive disorder (MDD) has demonstrated abnormalities of static intrinsic brain activity measured by amplitude of low-frequency fluctuation (ALFF). Recent studies regarding the resting-state functional magnetic resonance imaging (rs-fMRI) have found the brain activity is inherently dynamic over time.

Altered Spontaneous Brain Activity in Left-Behind Children: A Resting-State Functional MRI Study

Frontiers in Neurology, 2022
BackgroundParental migration has been associated with a higher risk of cognitive and behavioral abnormalities in left-behind children (LBC). This study aimed to explore the spontaneous brain activity in LBC and reveal the mechanisms underlying behavioral

Resting‐state amplitude of low‐frequency fluctuation is associated with suicidal ideation [PDF]

Depression and Anxiety, 2019
Identifying brain activity patterns that are associated with suicidal ideation (SI) may help to elucidate its pathogenesis and etiology. Suicide poses a significant public health problem, and SI is a risk factor for suicidal behavior.Forty-one unmedicated adult participants in a major depressive episode (MDE), 26 with SI on the Beck Scale for Suicidal ...

Altered Dynamic Amplitude of Low-Frequency Fluctuations in Patients With Migraine Without Aura [PDF]

Frontiers in Human Neuroscience, 2021
Migraine is a chronic and idiopathic disorder leading to cognitive and affective problems. However, the neural basis of migraine without aura is still unclear. In this study, dynamic amplitude of low-frequency fluctuations (dALFF) analyses were performed in 21 patients with migraine without aura and 21 gender- and age-matched healthy controls to ...

Convergent Functional Changes of Default Mode Network in Mild Cognitive Impairment Using Activation Likelihood Estimation

Frontiers in Aging Neuroscience, 2021
Background: Mild cognitive impairment (MCI) represents a transitional state between normal aging and dementia disorders, especially Alzheimer's disease (AD). The disruption of the default mode network (DMN) is often considered to be a potential biomarker
