Visual cortical surface area varies two- to threefold between human individuals, is highly heritable, and has been correlated with visual acuity and visual perception. However, it is still largely unknown what specific genetic and environmental factors contribute to normal variation in the area of visual cortex. To identify SNPs associated with the(More)
Multifactorial mechanisms underlying late-onset Alzheimer's disease (LOAD) are poorly characterized from an integrative perspective. Here spatiotemporal alterations in brain amyloid-β deposition, metabolism, vascular, functional activity at rest, structural properties, cognitive integrity and peripheral proteins levels are characterized in relation to LOAD(More)
Diabetes mellitus has long been considered a risk factor for the development of vascular dementia. Epidemiologic evidence has suggested that diabetes mellitus significantly increases risk for the development of Alzheimer's disease, independent of vascular risk factors. As insulin's role as a neuromodulator in the brain has been described, its significance(More)
Cardiovascular risk factors including hypertension (HTN) have been shown to increase the risk of Alzheimer disease. The current study investigated whether individuals with HTN are more susceptible to increased cognitive decline and whether the influence of HTN on cognitive decline varied as a function of dementia severity. A total of 224 nursing home and(More)
BACKGROUND This study examines whether the association of diabetes with the rate of cognitive decline varies according to dementia severity. METHODS Longitudinal study on subjects residing in nursing homes and assisted living (n = 342). The Mini Mental State Examination (MMSE) was used to measure the rate of cognitive decline in diabetic and nondiabetic(More)
BACKGROUND In cross-sectional and longitudinal studies, type 2 diabetes has been positively associated with the risk of Alzheimer's disease (AD). The present descriptive study compared diabetic and nondiabetic subjects on the severity of neuritic plaques and neurofibrillary tangles (NFTs) in the cerebral cortex and in the hippocampus. METHODS The study(More)
Dementia is an increasingly common diagnosis in our aging population, and the numbers are expected to rise exponentially in coming years. Alzheimer's disease alone now affects 4.5 million people in the US, while millions more are currently affected by vascular dementia, Lewy Body disease and frontotemporal dementia. Each of these is a distinct entity,(More)
AIMS To assess the relationships between early and late antemortem measures of dementia severity and Alzheimer disease (AD) neuropathology severity. METHODS 40 residents of a nursing home, average age at death 82.0, participated in this longitudinal cohort study with postmortem assessment. Severity of dementia was measured by Clinical Dementia Rating(More)

OBJECTIVE To compare the diagnostic accuracy of CSF biomarkers and amyloid PET for diagnosing early-stage Alzheimer disease (AD). METHODS From the prospective, longitudinal BioFINDER study, we included 122 healthy elderly and 34 patients with mild cognitive impairment who developed AD dementia within 3 years (MCI-AD). β-Amyloid (Aβ) deposition in 9 brain(More)
