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)
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)
This paper presents an energy efficient radio access network (RAN) selection for vertical handover between heterogeneous networks. The proposed RAN selection switches evaluation bases by application and adaptively selects a RAN with low energy consumption. In addition, the selection employs a penalty function that avoids discarded vertical handovers(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)
The effort-reward imbalance is an important psychosocial factor which is related to poor health among employees. However, there are few studies that have evaluated effort-reward imbalance among medical residents. The present study was done to determine the association between psychosocial factors at work as defined by the effort-reward imbalance model and(More)
