APOE is an established susceptibility gene for late-onset Alzheimer's disease (LOAD). Recent genome-wide association studies have identified many additional susceptibility genes for LOAD in populations of European descent. However, there is little information on whether or not genetic variants in these genes are associated with other ethnicities. To(More)
OBJECTIVE We investigated the association between glucose tolerance status defined by a 75-g oral glucose tolerance test (OGTT) and the development of dementia. METHODS A total of 1,017 community-dwelling dementia-free subjects aged ≥60 years who underwent the OGTT were followed up for 15 years. Outcome measure was clinically diagnosed dementia. RESULTS(More)
Diabetes mellitus (DM) is considered to be a risk factor for dementia including Alzheimer's disease (AD). However, the molecular mechanism underlying this risk is not well understood. We examined gene expression profiles in postmortem human brains donated for the Hisayama study. Three-way analysis of variance of microarray data from frontal cortex, temporal(More)
The associations between blood pressure and dementia have been inconclusive. We followed up a total of 668 community-dwelling Japanese individuals without dementia, aged 65 to 79 years, for 17 years and examined the associations of late-life and midlife hypertension with the risk of vascular dementia and Alzheimer disease using the Cox proportional hazards(More)
OBJECTIVE Takotsubo cardiomyopathy, which is characterized by transient left ventricular apical ballooning, is a known complication of subarachnoid hemorrhage. The aim of this study was to identify the clinical characteristics of acute ischemic stroke patients who experienced development of takotsubo cardiomyopathy. METHODS Seven patients who were(More)
OBJECTIVE Type 2 diabetes confers a greater excess risk of cardiovascular disease in women than in men. Diabetes is also a risk factor for dementia, but whether the association is similar in women and men remains unknown. We performed a meta-analysis of unpublished data to estimate the sex-specific relationship between women and men with diabetes with(More)
BACKGROUND Small deep brain infarcts are often caused by two different vascular pathologies: 1. atheromatous occlusion at the orifice of large caliber penetrating arteries termed branch atheromatous disease (BAD) and 2. lipohyalinotic degenerative changes termed lipohyalinotic degeneration (LD). We herein analyze and describe the characteristics of these 2(More)
BACKGROUND Progressive motor deficits (PMD) are common in cerebral penetrating artery disease (PAD) during the acute stage and leads to severe disability. Reliable predictors and stroke mechanism for PMD in PAD have been yet to be elucidated. Moreover, difference of predictors between topographically classified PAD has not ever been systematically studied.(More)
BACKGROUND Uncertainty still surrounds the association between metabolic syndrome (MetS) and depression. We aimed to evaluate the association between MetS and elevated depressive symptoms in a general Japanese population. METHODS This is a cross-sectional survey of 3,113 community-dwelling individuals aged 40 years or over. MetS was defined according to(More)
BACKGROUND AND PURPOSE Patients with acute lacunar infarction in the lenticulostriate artery (LSA) territory often show progression of motor deficits (PMD) after admission. The purpose of our study is to identify predictors for PMD using the findings of diffusion-weighted imaging (DWI) on admission. METHODS From January 2005 to December 2008, we studied(More)
