A 76-year-old man was referred to neurology by speech and language therapy after video fluoroscopy showed oropharyngeal dysphagia, aspiration, and tongue tremor (Video 1). He had presented with 6 months of progressive dysphagia, dysarthria, weight loss, and falls. Examination revealed akinetic rigidity, vertical supranuclear gaze palsy, slowed saccades, dysarthrophonia, and tongue tremor without palatal, jaw, or limb tremor. We diagnosed probable progressive supranuclear palsy (PSP). He did not respond to levodopa (400 mg/d). On a follow-up assessment 27 months later, the tremor persisted (Video 1). Tremor, usually upper limb, occurs in 42% of PSP cases.1 Isolated tongue tremor is a rare feature of PSP.1,2
