Effects of Anosognosia on Static and Dynamic Amplitudes of Low-Frequency Fluctuation in Mild Cognitive Impairment [PDF]

Frontiers in Aging Neuroscience, 2021
Background: Anosognosia is a significant symptom in patients with mild cognitive impairment (MCI) while the underlying neurological mechanism behind it is still unclear.Methods: A total of 121 subjects were included and classified into three groups, including 39 normal controls (NCs), 42 individuals with MCI without anosognosia (MCI-NA), and 40 ...

Decline in Executive Function in Patients With White Matter Hyperintensities From the Static and Dynamic Perspectives of Amplitude of Low-Frequency Fluctuations

Journal of Neuroscience Research, 2021
Abstract Cognitive impairments are characteristics of patients with white matter hyperintensities (WMHs), and hypoperfusion is currently a relatively recognized mechanism of WMHs. Brain activity is closely coupled to the regulation of local blood flow.

More Than Just Statics: Abnormal Dynamic Amplitude of Low-Frequency Fluctuation in Adolescent Patients With Pure Conduct Disorder

Journal of Psychiatric Research, 2020
The human brain activity is inherently dynamic over time. Conventional neuroimaging studies have reported abnormalities of static intrinsic brain activity or connectivity in adolescent patients with conduct disorder (CD). Little is known, however, regarding the temporal dynamics alterations of brain activity in CD.In this study, resting-state ...

More Than Just Statics: Altered Complexity of Dynamic Amplitude of Low-Frequency Fluctuations in the Resting Brain After Stroke

Journal of Neural Engineering, 2022
Abstract Objective. Previous neuroimaging studies mainly focused on static characteristics of brain activity, and little is known about its characteristics over time, especially in post-stroke (PS) patients.

Dynamic and static changes of amplitude of low-frequency fluctuations in anti‑N‑methyl‑D‑aspartate receptor encephalitis

Brain Imaging and Behavior, 2023
Previous neuroimaging research has examined static local brain activity changes in patients with anti-N-methyl-d-aspartate receptor (anti-NMDAR) encephalitis. However, the dynamic properties of local brain activity in anti-NMDAR encephalitis remain unknown.This study used a combination of the amplitude of low-frequency fluctuation (ALFF) method and a ...

Altered Static and Temporal Dynamic Amplitude of Low-Frequency Fluctuations in the Background Network During Working Memory States in Mild Cognitive Impairment

Frontiers in Aging Neuroscience, 2019
Previous studies investigating working memory performance in patients with mild cognitive impairment (MCI) have mainly focused on the neural mechanisms of alterations in activation. To date, very few studies have investigated background network alterations in the working memory state.

Dynamic and static changes of amplitude of low-frequency fluctuations associated with childhood trauma in youth major depression disorder patients with atypical features

Journal of Affective Disorders
Major depressive disorder (MDD) with atypical features often characterized with increased misdiagnosis and poor response to standard treatment. This research explores the neurobiological mechanisms underlying atypical depression (AD) by examining spontaneous brain activity and childhood trauma contrasting these findings with non-atypical depression ...

Static and dynamic changes in amplitude of Low-Frequency fluctuations in patients with Self-Limited epilepsy with centrotemporal Spikes (SeLECTS): A Resting-State fMRI study

Journal of Clinical Neuroscience
This study aims to explore differences in the static and dynamic amplitude of low-frequency fluctuations (sALFF and dALFF) in resting-state functional MRI (rs-fMRI) data between patients with Benign childhood epilepsy with centrotemporal spikes (SeLECTS) and healthy controls (HCs).We recruited 45 patient with SeLECTS and 55 HCs, employing rs-fMRI to ...
