Progressive supranuclear palsy (PSP) is a neurodegenerative disease, classified pathologically as a tauopathy, which all neurologists encounter from time to time. Andrew Larner made the intriguing suggestion that Charles Dickens may have been the first to describe someone with PSP in 1857 in his novel The lazy tour of two idle apprentices:

These quotes are certainly suggestive of a character with several features with more than a passing resemblance to PSP.1 From the medical perspective, Dutil, one of Charcot’s pupils, may have described and illustrated the first documented case of PSP in 1889.2 Another early description of the clinical syndrome in 1904 later transpired to be due to a mesencephalic tumour rather than PSP.3 In the early 20th century, cases of PSP were probably misdiagnosed as either arteriosclerotic or post-encephalitic parkinsonism.4 PSP (also known as the Steele-Richardson-Olszewski syndrome) was first described as a clinicopathological entity at the American Neurological Association by Dr J Clifford Richardson in 1963.
