Abstract

PURPOSE OF REVIEW: Neurodegenerative tauopathies, of which progressive supranuclear palsy (PSP) is one of the most common, are clinically heterogeneous, reflecting differences in distribution and biochemical composition of tau pathology. This review highlights the range of clinical and pathologic presentations of PSP and its variants. RECENT FINDINGS: Progressive supranuclear palsy is a 4R tauopathy with neuronal and glial tau-immunoreactive lesions in neuroanatomically specific nuclei in the basal ganglia, diencephalon, brainstem and cerebellum, with restricted involvement of the neocortex. Hierarchical cluster analyses of clinical and pathologic features of PSP indicate that there are distinct clinicopathologic variants of PSP. In variants of PSP presenting with focal cortical syndromes, such as frontotemporal dementia, corticobasal syndrome and apraxia of speech, there is greater cortical pathology than in typical PSP. In variants of PSP presenting with levodopa-responsive Parkinsonism, as well as pure akinesia and gait failure, there is less cortical pathology and more severe degeneration in the cardinal nuclei - globus pallidus, subthalamic nucleus and substantia nigra - than in typical PSP. SUMMARY: Clinical variants in PSP reflect varying anatomical distribution of tau pathology, but they share histopathologic, biochemical and genetic features with typical PSP. The basis for anatomical selective vulnerability in PSP and its variants remains to be determined.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The spatial distribution of the in vivo association between microglial activation and tau pathology in PSP mirrors previous findings that tau pathology affects both subcortical and cortical regions in PSP Richardson's syndrome.

    “The spatial distribution of this in vivo association between microglial activation and tau pathology in PSP mirrors previous findings showing that tau pathology affects not only subcortical but also cortical regions in PSP Richardson’s syndrome42,43.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
