Research Abstract |
Progressive supranuclear palsy(PSP) is a neurodegenerative disorder that is characterized by parkinsonism and dementia. However, the aged patients with PSP did not always show both parkinsonism and dementia. We investigated retrospectively the clinical data of 51 autopsy-proven cases with PSP to clarify their clinicopathological multiplicity. Among 51 patients with PSP,21 cases showed typical neurological symptoms compatible to PSP, but 20 cases did not show apparent parkinsonism and could go about their daily life without any problem. Among 20 PSP patients lacking obvious parkinsonism,14 cases presented only dementia (mean age:85.5±7.5) and six cases did not show obvious parkinsonism nor dementia (mean age:90.5±9.8). The mean age of PSP cases without parkinsonism was significantly higher than that of PSP cases with parkinsonism. But there is no significant difference in the brain weight of PSP patients between those with and without parkinsonism. Only two cases with PSP showed cerebellar ataxia, but the distribution and severity of lesions were same as those of other PSP cases. Parts pf the aged PSP patients, though a few in number, showed only dementia.
