The borderline zone condition between normal aging and dementia is a major issue of concern. Although the term mild cognitive impairment (MCI) is popular, its prevalence and neuropsychological features have not been fully investigated. We investigated the prevalence and neuropsychological features for Clinical Dementia Rating (CDR) 0.5 and MCI. For normal(More)
This study presents a thorough analysis of published crossed aphasia (CA) cases, including for the first time the cases published in Japanese. The frequency of specific symptoms was determined, and symptomatology differences based on gender, familial sinistrality, and CA subtype were investigated. Results suggested that the CA population is comparable to(More)
Algebraic computation with oating-point numbers often causes large numerical errors due to cancellation of almost the same numbers. In this paper, we is a set of numbers, and analyze the cancellation errors contained in the coeecients of G k and H k , in the case that the expansion point i.e. u = s is near a singular point. Let be the distance between the(More)
Recently, cell-based therapy has gained significant attention for the treatment of central nervous system diseases. Although bone marrow stromal cells (BMSCs) are considered to have good engraftment potential, challenges due to in vitro culturing, such as a decline in their functional potency, have been reported. Here, we investigated the efficacy of rat(More)
Relatively high rates of loosening and implant failure have been reported after total ankle arthroplasty, especially in first and second generation implants. Abnormal kinematics and incongruency of the articular surface may cause increased loads applied to the implant with concomitant polyethylene wear, resulting in loosening and implant failure. The(More)
BACKGROUND The Mini-mental State Examination (MMSE) is widely used in Japan and the U.S.A. for cognitive screening in the clinical setting and in epidemiological studies. A previous Japanese community study reported distributions of the MMSE total score very similar to that of the U.S.A. METHODS Data were obtained from the Monongahela Valley Independent(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)
