In patients with pemphigus vulgaris (PV), autoantibodies against desmoglein 3 (Dsg3) cause loss of cell-cell adhesion of keratinocytes in the basal and immediate suprabasal layers of stratified squamous epithelia. The pathology, at least partially, may depend on protease release from keratinocytes, but might also result from antibodies interfering with an(More)
BACKGROUND Several studies have reported that the prevalence of idiopathic normal-pressure hydrocephalus (iNPH) was between 0 and 5%. However, the precise prevalence in a community-based elderly population remains unclear. We investigated the prevalence of possible iNPH retrospectively using an age- and gender-stratified random sample database. METHODS(More)
Prevalence, magnetic resonance imaging (MRI) findings, cognitive function and depression are four major aspects of vascular cognitive impairment no dementia (vascular CIND). We performed a community-based study to examine these using 497 community-residents aged 65 years or older. Vascular CIND was defined as a clinical dementia rating (CDR) 0.5 with(More)
BACKGROUND Several follow-up [18F]fluorodeoxy glucose (FDG)-positron emission tomography (PET) studies have been performed in patients with mild cognitive impairment, but none have examined subjects with a Clinical Dementia Rating (CDR) of 0.5. Therefore, we used FDG-PET to investigate whether baseline glucose metabolism (CMRglc) in CDR 0.5 converters to(More)
WHAT IS ALREADY KNOWN ABOUT THIS SUBJECT * Deficit in central cholinergic neurotransmission is a consistent change associated with Alzheimer's disease (AD). * Donepezil hydrochloride exhibits selective inhibition of acetylcholinesterase (AChE) and is widely used for the treatment of AD. * The biodistribution of donepezil in the brain after administration is(More)
There have been no systematic efforts to manage and treat patients with frontotemporal dementia (FTD), but Perry described pharmacologic interventions for some behavioral syndromes in 2001. In Perry's report, selective serotonin reuptake inhibitors (SSRI) were recommended as first choice drugs because they were well tolerated and might have an effect on(More)
Deficits in the cholinergic system are pronounced in dementia with Lewy bodies (DLB) and are more severe in patients with visual hallucinations (VHs). The aim is to identify the occipital glucose metabolism patterns by positron emission tomography (PET) and the changes following donepezil treatment. 13 DLB patients with VHs were enrolled in the study. After(More)
BACKGROUND There have been no reports on the prevalence of dementia among the old-old people in Japan. METHODS We studied the old-old population in Kurihara, northern Japan. Analysis 1 of Participants 1 (n=590) was performed to evaluate the prevalence of dementia and dementing diseases by intensive evaluation including MRI. Analysis 2 aimed to determine a(More)
