The Alzheimer Disease Genetics Consortium (ADGC) performed a genome-wide association study of late-onset Alzheimer disease using a three-stage design consisting of a discovery stage (stage 1) and two replication stages (stages 2 and 3). Both joint analysis and meta-analysis approaches were used. We obtained genome-wide significant results at MS4A4A(More)
CONTEXT Exercise training for patients with Alzheimer disease combined with teaching caregivers how to manage behavioral problems may help decrease the frailty and behavioral impairment that are often prevalent in patients with Alzheimer disease. OBJECTIVE To determine whether a home-based exercise program combined with caregiver training in behavioral(More)
BACKGROUND Alzheimer disease and other dementing disorders are major sources of morbidity and mortality in aging societies. Proven strategies to delay onset or reduce risk for dementing disorders would be greatly beneficial. OBJECTIVE To determine whether regular exercise is associated with a reduced risk for dementia and Alzheimer disease. DESIGN(More)
CONTEXT Age-specific incidence rates for dementia and Alzheimer disease (AD) are important for research and clinical practice. Incidence estimates for the United States are few and vary with the population sampled and study design; we present data that will contribute to a consensus of these rates. OBJECTIVES To provide age-specific incidence estimates(More)
To set a working cutoff score for the referral to diagnostic examination, we evaluated 150 consecutive patients with complaints potentially related to dementia, using the Mini-Mental State Examination (MMSE). All patients were later given a complete, standardized work-up and diagnosis as part of our Alzheimer's Disease Patient Registry protocol. Dementia(More)
OBJECTIVE To determine whether olfactory status predicts cognitive decline (CD) over a 2-year follow-up period. METHODS The authors enrolled individuals in a community-based longitudinal study of memory and aging in the Japanese-American community in King County, WA, between 1992 and 1994. At baseline they screened 1,985 persons using the Cognitive(More)
BACKGROUND Hippocampal sclerosis (HS) is a neuropathologic finding characterized by neuronal loss and gliosis in the CA-1 and subiculum of the hippocampus. Previous studies of HS have shown that this is a common postmortem finding in elderly subjects with dementia. However, these studies were from selected samples and therefore are not necessarily(More)
OBJECTIVE To examine the neuropsychological profile of dementia patients from a community-based autopsy sample of dementia, comparing Alzheimer disease (AD), Lewy body pathology (LBP) alone, and LBP with coexistent AD (AD/LBP). METHODS The authors reviewed 135 subjects from a community-based study of dementia for whom autopsy and brain tissue was(More)
Studies of Asian populations generally have reported prevalence rates for dementia similar to those of predominantly Caucasian populations, but relative prevalence rates of Alzheimer's disease and vascular dementia have differed. Between May 1, 1992 and May 1, 1994, the prevalence rates of dementia, Alzheimer's disease, and vascular dementia were examined(More)
OBJECTIVES To examine the association of serum total cholesterol (TC) and high density lipoprotein (HDL) levels and subsequent incidence of dementia and Alzheimer disease (AD) in a population-based cohort study. METHODS A cohort of cognitively intact persons, aged 65 and older, was randomly selected from Group Health Cooperative (GHC), a large health(More)
