| Outline of Final Research Achievements |
Progressive supranuclear palsy (PSP) cases frequently have argyrophilic grain disease (AGD). However, the frequency of neurofibrillary tangles and tufted astrocytes in the subcortical nuclei and frontal cortex in AGD cases remains unclear. To address these issues, we examined tau-positive inclusions in these regions in 19 AGD cases, nine pathologically-confirmed PSP cases, and 20 controls. Our results suggested that the progression of AGD may be associated with the development of PSP-like tau pathologies, and a common pathological process may lie upstream of the occurrence of AGD and PSP pathology, although these diseases have been considered different. In the present study, the clinicopathological correlation between mild tau pathology in the subcortical nuclei and clinical features could not be examined, because detailed neurological data on our AGD cases were not available. Further studies will be needed.
