Motor, cognitive and behavioral differences in MDS PSP phenotypes

ConclusionAvailable clinical assessments hardly capture differences between PSP phenotypes. The cognitive testing differentiating the PSP phenotypes were semantic fluency and ideomotor apraxia. In PSP, mild cognitive impairment likely represents an intermediate step from normal cognition to dementia. The only marker of PSP non-Richardson ’s syndrome phenotype was better performance in visuo-spatial testing.
