Longitudinal Videofluorographic Dysphagia Measures in Progressive Supranuclear Palsy.
Key Points
To investigate the progression of dysphagia and lingual pressure over time in patients with progressive supranuclear palsy (PSP).
Longitudinal assessments were conducted using videofluorography to evaluate dysphagia.
Different PSP variants were analyzed for rates of dysphagia change.
Correlation between dysphagia and rates of atrophy was examined.
Dysphagia worsened over time in patients with PSP.
There was variability in rates of change in the OTSS among different PSP variants.
Dysphagia severity is linked to the rates of brain atrophy.
Abstract
Dysphagia and lingual pressure worsen over time in PSP, with variability in rates of change in the OTSS across PSP variants and evidence that dysphagia is related to rates of atrophy.
