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.
