Progressive supranuclear palsy.
In this case study, we describe the symptoms, neurological examination, clinical course, and neuropathology of a patient with progressive supranuclear palsy (PSP). PSP is a relatively uncommon neurodegenerative disorder with many features similar to those of Parkinson's disease. It is characterized by slow motor function, ocular movement abnormalities, dystonia, and cognitive disabilities. PSP is largely a sporadic disorder caused by accumulation of the protein tau in diverse regions of the central nervous system. It is thus classified as one of several tauopathies. The exact cause of the disease remains unknown, and treatment is often limited. The following case provides a framework to explore the manifestations of PSP, as well as the progress made in understanding the nature of this challenging disorder.
