The apolipoprotein E type 4 allele (APOE-epsilon 4) is genetically associated with the common late onset familial and sporadic forms of Alzheimer's disease (AD). Risk for AD increased from 20% to 90% and mean age at onset decreased from 84 to 68 years with increasing number of APOE-epsilon 4 alleles in 42 families with late onset AD. Thus APOE-epsilon 4(More)
Gene dosage of the apolipoprotein E (APOE) epsilon 4 allele is a major risk factor for familial Alzheimer disease (AD) of late onset (after age 60). Here we studied a large series of 115 AD case subjects and 243 controls as well as 150 affected and 197 unaffected members of 66 AD families. Our data demonstrate a protective effect of the epsilon 2 allele, in(More)
HIV produces a chronic viral infection of the central nervous system that elicits chronic glial activation and overexpression of glial cytokines that are also implicated in Alzheimer disease (AD) pathogenesis. A genetic risk factor for AD is the E4 isoform for apolipoprotein E (APOE). Here we compare the frequency of neurologic symptoms for subjects with(More)
This study evaluates the risk of prostate cancer in relation to serum levels of the major vitamin D metabolites, 25-hydroxyvitamin D (25-D3) and 1,25-dihydroxyvitamin D (1,25-D). Between 1964 and 1971, more than 250,000 serum samples were collected from members of the Kaiser Permanente Medical Care Plan in Oakland and San Francisco and stored for future(More)
Cystatin C, a protease inhibitor with widespread distribution, is upregulated in response to injury. Levels are elevated in the brains of patients with Alzheimer disease (AD). We compared frequencies for the CST 3 exon 1 polymorphism in patients with AD and controls. A proportional odds model indicated that the CST 3 A and APOE4 combination carried a high(More)
Epidemiologic and laboratory results consistently implicate the APOE gene in the pathogenesis of late-onset Alzheimer's disease (AD) the ε4 allele increases risk in a dose-dependent fashion, while ε2 confers protection. Individuals are susceptible for AD in varying degrees depending on which combination of APOE alleles has been inherited, APOE promoter(More)
A genetic classification of Alzheimer disease(s) (AD) is presented. We describe a potential metabolic process in individuals who inherit apolipoprotein E-epsilon 4 (APOE4, gene; apoE4, protein) alleles, leading to increased risk and earlier age of onset of late-onset Alzheimer disease. Apolipoprotein E-epsilon 3 (apoE3) binds to tau protein, possibly(More)
Epidemiologic studies indicate that elderly women are at higher risk for Alzheimer disease compared to men. In order to pathologically verify this result, the extent of AD brain lesions (NFT and SP) was compared for men and women at each age, that is, at each decade from 25 years to 95 years, in a large sample of > 5000 routine autopsy cases. Women had more(More)
OBJECTIVE To quantify the influence of apolipoprotein E (APOE) polymorphism on cognition and survival in a population sample aged 75 years or older. DESIGN The Kungsholmen Project established a cohort of 1810 residents in a district in Stockholm, Sweden, aged 75 years or older in 1987. Information on cognition at cohort inception is available for all(More)
Alzheimer's disease is a complex neurodegenerative disorder, characterized by progressive cognitive decline and distinct neuropathology. The apolipoprotein gene E4 allele (APOE 4) is a major risk factor for the disease. Promoter polymorphisms at -491 and -427 may also contribute to the risk. We examined the two polymorphisms in 178 Alzheimer's patients and(More)
