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)
BACKGROUND AND PURPOSE Fluid-attenuated inversion recovery vascular hyperintensity (FVH) is often identified in patients with acute ischemic stroke. The purpose of this study was to determine the clinical significance of FVH in patients with transient ischemic attack (TIA). METHODS Consecutive inpatients with TIA who underwent MRI within 24 hours of(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)
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 To our knowledge, there are no previous reports that assessed the association between dietary patterns and risk of dementia in Asian populations. OBJECTIVE We investigated dietary patterns and their potential association with risk of incident dementia in a general Japanese population. DESIGN A total of 1006 community-dwelling Japanese(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)
BACKGROUND There is little information regarding whether the combination of Helicobacter pylori (H. pylori) antibody and serum pepsinogen (sPG), which is a marker of the degree of atrophic gastritis, has a discriminatory ability for detecting incident gastric cancer. We examined this issue in a long-term prospective cohort study of a Japanese population. (More)
BACKGROUND/AIMS The aims of this study were to determine the differences in clinical characteristics and the risk of ischemic stroke between patients with transient ischemic attack (TIA) attributable to extracranial carotid and intracranial artery occlusive lesions. METHODS Among 445 patients admitted to our stroke care unit within 48 h of TIA onset(More)
Although the relationships between chronic kidney disease (CKD) and cognitive impairment (CI) have been highlighted, the etiology of CI in CKD remains uncertain. Subjects comprised 224 consecutive patients with symptomatic lacunar infarction who underwent magnetic resonance imaging and ambulatory blood pressure monitoring (ABPM). Diurnal blood pressure (BP)(More)
