The APOE-epsilon 4 allele is the strongest known genetic risk factor for AD. The authors performed a meta-analysis to establish the predictive accuracy of the APOE-epsilon 4 allele for progression from MCI to AD-type dementia.Methods The authors included 35 prospective cohort studies of subjects with MCI, including 6095 subjects, of whom 1236 progressed to AD-type dementia after 2.9 years of follow-up. However, the «4 allele has recently been reported to also be more frequent in patients with sporadic Alzheimer's disease (40% in patients with Alzheimer's disease compared with 10% to 16% of control subjects),1-3-4 raising questions about the specificity of €4 as a risk factor for cerebrovascular or Alzheimer's3 disease. 1996-10-01 This could explain ingly, recent evidence points to a gene–gene interaction why the APOE epsilon 4 allele was associated with IL-1, between methylenetetrahydrofolate reductase (MTHFR) but not with other pro-inflammatory cytokines in our c.677C>T (A222V) polymorphism and APOE geno- study.

Carrying an APOE4 allele is recognised as a genetic risk factor of late-onset Alzheimer’s disease (LOAD) and coronary heart disease (CHD). Consuming fatty fish, rich APOE gene regulates the expression of this protein and has three different alleles: ε2, ε3 and ε4. Carrying an APOE4 allele is recognised as a genetic risk factor of late-onset Alzheimer’s disease (LOAD) and coronary heart disease (CHD). Background: Although the significance of apolipoprotein E4 (Apo E4) in Alzheimer's disease (AD) has been well established in Caucasian populations, its role in determining the rate of cognitive decline in other ethnic groups has yet to be determined This study examined the two-year progression of cognitive decline and its association with Apo E4 allelic status in a group of Chinese elderly diseases.

From clinically based series it has been proposed that, in homozygotes for the apolipoprotein E epsilon 4 (apoE epsilon 4) allele, Alzheimer's disease is almost inevitable by the age of 80. A population sample of persons aged 70 years and over was interviewed in 1990-91 to ascertain the presence of dementia or cognitive impairment.

Apoliprotein E, type {epsilon}4 allele (ApoE-{epsilon}4) is associated with late-onset sporadic Alzheimer`s disease (AD). We have found that the cumulative probability of remaining unaffected over time decreases for each dose of ApoE-{epsilon}4 in sporadic, late-onset French AD. Many clinical and basic studies have confirmed an association between the apolipoprotein E (apoE) epsilon 4 allele and the development of Alzheimer's disease (AD). Corder et al. [1] reported that survival from onset was unrelated to epsilon 4 gene dose. In this issue, Kurz et al.

CONCLUSIONS: APOE epsilon4 allele is more frequent in children with obstructive sleep apnea and particularly in those who develop neurocognitive deficits, suggesting that the APOE epsilon4 allele is associated with not only increased The apolipoprotein E (APOE) epsilon 4 allele is known to influence risk of AD but it has been difficult to establish whether it affects episodic memory differently from other cognitive functions.

The APOE epsilon 4 allele is associated with cognitive decline and the development of dementia in the general population as well as in patients with TBI. These findings raise the question of whether patients with TBI who are APOE epsilon 4 allele carriers are more vulnerable to the negative effects of sleep apnea on their cognitive functioning. As we did observe a possible additive interaction between the APOE ε4 allele and low physical activity for AD risk, APOE ε4 carriers may particularly benefit from an active lifestyle. Although we did not find a gene–environment interaction for general dementia risk, a protective effect of physical activity on the risk for dementia was found in both APOE ε 4 allele carriers and non-carriers. Results: The presence of at least one epsilon 4 allele was associated with faster cognitive decline in the incident population-based AD group (p = 0.01). Parallel results were produced for the two prevalent dementia samples only when adjusting for disease severity or excluding the most impaired participants from the analyses.
