In the present case, a patient in whom limb apraxia and asymmetrical parkinsonism developed suggesting corticobasal degeneration, is reported. Neuropathologic examination revealed numerous tufted astrocytes in the precentral cortex in addition to the characteristic pathologic findings of PSP. Therefore, on the basis of clinicopathologic features, atypical(More)
Lithium, a drug used to treat bipolar disorders, has a variety of neuroprotective mechanisms including inhibition of glycogen synthase kinase-3 (GSK-3), a major tau kinase. Recently, it has been shown that, in various neurodegenerative proteinopathies, lithium could induce autophagy. To analyze how lithium is therapeutically beneficial in tauopathies,(More)
Apolipoprotein E receptor 2 (apoER2) is a receptor for apolipoprotein E containing lipoprotein and also for Reelin. Apolipoprotein E-associated risk of developing Alzheimer's disease (AD) may be related to its binding to and clearance by cell surface receptors, including members of the low-density lipoprotein receptor family. Otherwise there is(More)
Phosphorylated tau (p-tau) is the principal component of neurofibrillary tangles, a pathological hallmark, and likely plays a neurotoxic role in tauopathies including Alzheimer's disease (AD), progressive supranuclear palsy (PSP), and corticobasal degeneration (CBD). We subjected brains from autopsy cases of AD, PSP, and CBD to a variety of(More)
Parkinson disease (PD) and dementia with Lewy bodies (DLB) are considered Lewy body diseases (LBDs). To clarify the relation between PD with dementia (PDD) and DLB, 30 patients with LBD were divided into pathological subtypes according to the consensus guidelines for DLB. Patients with PDD showed neocortical and limbic type of LBD as well as patients with(More)
