No association between Alzheimer's disease (AD) and apolipoprotein E type epsilon 4 (ApoE epsilon 4) phenotype was found among centenarians in Finland (N = 179). The data are based on ascertainment of all centenarians in Finland in 1991. All examinations were conducted during 1991. The diagnoses of dementia and AD were based on clinical grounds, conforming to DSM-III-R and NINCDS-ADRDA criteria. The percentage of ApoE epsilon 4 alleles among the centenarians was 8.7% (31 of 358 alleles). This is significantly lower than percentages found in younger Finnish populations. Thirty (16.8%) of the 179 centenarians were epsilon 4 allele carriers. One hundred fifty-one (84.4%) of the centenarians were women. Twenty-eight (18.5%) of the women had at least one epsilon 4 allele, as did two (7.1%) of the men. The prevalence of clinically diagnosed AD was 26.8%; 44% of the subjects were cognitively normal, 23% had signs of cognitive decline or at most mild dementia (with no differential diagnosis), and 6% had a dementia clinically diagnosed as being due to some cause other than AD. For AD cases versus cognitively normal subjects, the odds ratio associated with being a carrier of the epsilon 4 allele was 1.34 (p = 0.64; 95% CI = [0.5, 3.3]). Among women, the odds ratio was 0.99 (p = 1.0; 95% CI = [0.4, 2.6]). There were fewer, but not significantly so, epsilon 4 carriers among subjects with cognitive decline or at most mild dementia (12.2%) than there were among the cognitively normal subjects (16.5%). The AD patients had no evidence of difficulty standing on a flat stationary surface unless the surface suddenly moved.(ABSTRACT TRUNCATED AT 250 WORDS)

D000544 Alzheimer Disease A degenerative disease of the BRAIN characterized by the insidious onset of DEMENTIA. Impairment of MEMORY, judgment, attention span, and problem solving skills are followed by severe APRAXIAS and a global loss of cognitive abilities. The condition primarily occurs after age 60, and is marked pathologically by severe cortical atrophy and the triad of SENILE PLAQUES; NEUROFIBRILLARY TANGLES; and NEUROPIL THREADS.

D001057 Apolipoproteins E A class of protein components which can be found in several lipoproteins including HIGH-DENSITY LIPOPROTEINS; VERY-LOW-DENSITY LIPOPROTEINS; and CHYLOMICRONS. Synthesized in most organs, Apo E is important in the global transport of lipids and cholesterol throughout the body. Apo E is also a ligand for LDL receptors (RECEPTORS, LDL) that mediates the binding, internalization, and catabolism of lipoprotein particles in cells. There are several allelic isoforms (such as E2, E3, and E4). Deficiency or defects in Apo E are causes of HYPERLIPOPROTEINEMIA TYPE III.
