Abstract

The clinical features of the genetically determined forms of familial Parkinson’s disease (PD) have been described in multiple reports, but there have been few comparative neuropathologic studies. Five familial PD cases, with mutations in SNCA, were matched for age, sex, and Alzheimer type pathology with sporadic PD cases. Immunohistochemistry for phospho-tau and α-synuclein was performed in 8 brain regions. The frequency of tau pathology and the morphologic features of α-synuclein pathology in familial PD were compared with sporadic PD using semi-quantitative methods. In familial PD, there were significantly more tau positive extra-perikaryal spheroid-like and thread-like lesions than in the sporadic PD. There was no significant difference in the amount of α-synuclein positive neuronal perikaryal pathology between familial PD and sporadic PD, but α-synuclein positive oligodendroglial and neuritic lesions were significantly greater in familial PD compared to sporadic PD. In the substantia nigra, familial PD had more marked neuronal loss and fewer residential neurons with Lewy bodies than the sporadic PD, suggesting a close relationship between the severity of neuronal loss and Lewy body formation. The results show a diversity of pathological features of genetically determined familial PD, and they draw attention to the possible role of tau protein in neurodegeneration. Moreover, the presence of oligodendroglial inclusions at the light and electron microscopic levels in familial PD suggests that PD and multiple system atrophy form a continuum of α-synuclein pathology.
