Hidden Signs – Tauopathies & Early Movement Disorder Features

This session provides a practical, case-based overview of progressive supranuclear palsy (PSP) and related tauopathies, with a focus on recognising early clinical “hidden signs” that are frequently missed in routine practice. It places PSP within the broader tauopathy spectrum before exploring the clinical heterogeneity of PSP phenotypes and how this contributes to diagnostic delay. The discussion highlights updated diagnostic criteria and high-yield bedside red flags—such as early falls, gait freezing, axial rigidity, oculomotor abnormalities, and poor levodopa response—supported by real-world clinical cases and patient video examples.
