    Abstract:
    We described an autopsy case of 79-year-old woman with clinically unclassified senile dementia. The patient developed forgetfulness at the age of 73, and later, persecution mania, apathy and episodic stupor, but no extrapyramidal symptoms. Neuropathological examination revealed severe neuronal loss and gliosis of substantia nigra, moderate neuronal loss and marked grumose degeneration of dentate nucleus, and mild astrocytosis of subthalamic nucleus. Abundant neurofibrillary tangles (NFT) were observed in subthalamic nucleus, globus pallidus, substantia nigra, locus ceruleus, tegmentum of brain stem, pontine nucleus, inferior olive, and dentate nucleus. Gallyas silver impregnation method showed a wide distribution of argyrophilic grains and threads in cerebrum, brain stem and cerebellum. Although absence of clinical and neuropathological hallmarks excluded the diagnosis of progressive supranuclear palsy (PSP), the distribution of NFT and argyrophilic grains in this patient resembled PSP.
