The tau deposits found in neurodegenerative diseases are classified based on their isoforms, that is, 3-repeat (3R) tau and 4-repeat (4R) tau. These isoforms are distinguishable using the antibodies RD3 and RD4, respectively, and Gallyas (Gal) and Campbell-Switzer (CS) silver staining methods, respectively. Tau is also deposited in cerebral infarcts. To(More)
We report autopsy findings of 2 patients with the clinical diagnosis of dementia with Lewy bodies (DLB) both with Alzheimer disease (AD) pathology. Lewy bodies and cardiac sympathetic nerve depletion were found in case 1, while these pathological changes were both absent in case 2 with pure AD pathology. This autopsy-verified contrast was detectable through(More)

He had not received any recent vaccinations. He had no loss of consciousness. Bilateral ophthalmoplegia, blepharoptosis, areflexia, and ataxic gait were noted. One week after treatment with(More)
OBJECTIVE Pathogenesis of pseudohypertrophy of the inferior olivary nucleus (PH-IO) was analyzed based on immunohistochemical study. METHODS Immunostained medullas with PH-IO were observed with confocal laser microscopy. RESULTS αB-crystallin (αBC) was frequently expressed in the neurons and co-localized with microtubule-associated protein 2 (MAP2). The(More)
"Acute non-herpetic encephalitis" was consisted of several non-herpetic encephalitides including "acute juvenile female non-herpetic encephalitis (AJFNHE)" and "non-herpetic limbic encephalitis(NHLE)". In 1997, we first reported five young adult female patients with acute non-herpetic encephalitis who presented with severe prolonged coma and status(More)
