TL;DR: Clinical diagnostic criteria, published in 1996 by the National Institute of Neurological Disorders and Stroke/Society for PSP have excellent specificity, but their sensitivity is limited for variant PSP syndromes with presentations other than Richardson's syndrome.

TL;DR: The phenotypic spectrum of progressive supranuclear palsy may be broader and more variable than previously described in single‐center studies, and too strict clinical criteria defining distinct phenotypes may not reflect this variability.

TL;DR: Progressive supranuclear palsy is a neuropathologically defined disease presenting with a broad spectrum of clinical phenotypes, and there is no known cure for this disease.

TL;DR: This work aimed to study the frequency of ambiguous multiple allocations and to develop rules to eliminate them.

TL;DR: The observations indicate that progression of PD is slower in EOPD and suggest that the pre-clinical interval in this group is longer, which can be used for case selection for drug trials and studies of the pathogenesis of PD.
