Prefrontal Neurovascular Coupling Abnormalities Associated With Cognitive Performance in Multiple Sclerosis. [PDF]

CNS Neurosci Ther
Multimodal MRI showed reduced global CBF‐ALFF coupling and increased medial prefrontal CBF/ALFF ratios in multiple sclerosis. The mPFC abnormality was associated with lower cognitive performance and greater disability. ABSTRACT Background Cognitive impairment is a prevalent and debilitating feature in multiple sclerosis (MS), yet its pathophysiology ...

Altered Neurovascular Coupling Dynamics During Dobutamine-Induced Acute Stress. [PDF]

Brain Behav
ABSTRACT Background Neurovascular coupling (NVC) is essential for regulating brain metabolism and energy supply and may be altered under acute stress. This study aimed to investigate how acute stress induced by dobutamine affects NVC. Materials and methods This study enrolled 38 healthy participants undergoing a resting‐state fMRI scan and an arterial ...

Impact on ALFF and ReHO mapping of lifestyle multidomain intervention: The SUPERBRAIN study [PDF]

Alzheimer's & Dementia, 2021
AbstractBackgroundIn the South Korean study to prevent cognitive impairment and protect brain health through lifestyle intervention in at‐risk elderly people (SUPERBRAIN), we explored impact on amplitude of low‐frequency fluctuation (ALFF) and regional homogeneity (ReHo) mapping of 24‐week facility‐based multidomain intervention (FMI) and home‐based MI

ALFF and ReHo Mapping Reveals Different Functional Patterns in Early- and Late-Onset Parkinson’s Disease [PDF]

Frontiers in Neuroscience, 2020
Heterogeneity between late-onset Parkinson's disease (LOPD) and early-onset Parkinson's disease (EOPD) is mainly reflected in the following aspects including genetics, disease progression, drug response, clinical manifestation, and neuropathological change.
