Neural Correlates of Apathy in Multiple System Atrophy: A Clinical and Perfusion Imaging Study

ABSTRACT Background Apathy is a frequent nonmotor symptom of multiple system atrophy (MSA) that worsens quality of life. Although frontostriatal dysfunction has been implicated in apathy, its neural basis in MSA remains insufficiently characterized. Objectives To identify the neural substrates of apathy associated with...

Cerebral perfusion correlates of domain-specific cognitive function in Alzheimer's disease and dementia with Lewy bodies

Distinct patterns of cerebral perfusion-cognition relationships characterize AD and DLB, reflecting differential regional vulnerabilities underlying cognitive decline, which may contribute to improved understanding of the pathophysiology underlying cognitive decline and support disease monitoring.

Spatiotemporal Tau Accumulation and its Clinical Impact on Progressive Supranuclear Palsy: Longitudinal Florzolotau (18F) Positron Emission Tomography.

BACKGROUND Florzolotau (18F) positron emission tomography (florzolotau PET) enables high-contrast in vivo detection of four-repeat tau pathology in progressive supranuclear palsy (PSP), but whether longitudinal tau imaging reflects disease progression remains unclear. OBJECTIVES To explore longitudinal tau accumulati...
