Disruptions of neural metabolism and function occur in parallel during Alzheimer's disease (AD). While many studies have shown diverse metabolic‐functional relationships in specific brain regions, much less is known about how large‐scale network‐level functional activity is associated with the topology of metabolism in AD. In this study, we took the advantages of simultaneous PET/MRI and multivariate...
Background
The central autonomic network (CAN) plays a critical role in the body's sympathetic and parasympathetic control. However, functional connectivity (FC) changes of the CAN in patients with multiple system atrophy (MSA) remain unknown.
Purpose
To investigate FC alterations of CAN in MSA patients.
Study Type
Prospective.
Population
Eighty‐two subjects (47 patients with MSA [44.7% female,...
