Topic: Genetics and APOE
Apolipoprotein E (ApoE) is the major lipid-carrier protein in the brain, and several studies provided evidence that ApoE epsilon4 allele can be considered a genetic risk factor for vascular diseases. Findings indicate that Alzheimer disease (AD) and vascular dementia (VaD) may have common risk factors and/or pathogenesis, but their interrelationships still need to be clearly defined. Since ApoE4 imparts risk for both hyperlipidemia and AD, it seemed worthwhile to investigate the possible role of ApoE in the pathogenesis of AD and VaD. To this task, we examined in healthy volunteers, and AD and VaD patients: i) the frequency of ApoE isoforms; and ii) the influence of ApoE genotype on serum lipid levels. Our findings suggest that epsilon4 allele is an important risk factor for the development not only of the Alzheimer type, but also of the vascular type of dementia. In contrast, epsilon2 allele could have a protective role in AD dementia. These results confirm the hypothesis that serum ApoE concentration is dependent on ApoE genotype, but do not support the view that it has to be considered a relevant biochemical marker for AD and VaD.
Key findings
- Findings indicate that Alzheimer disease (AD) and vascular dementia (VaD) may have common risk factors and/or pathogenesis, but their interrelationships still need to be clearly defined.
- Our findings suggest that epsilon4 allele is an important risk factor for the development not only of the Alzheimer type, but also of the vascular type of dementia.
- These results confirm the hypothesis that serum ApoE concentration is dependent on ApoE genotype, but do not support the view that it has to be considered a relevant biochemical marker for AD and VaD.

How this study scored 38/100
Published in a peer-reviewed journal. Scored zero for study design, sample size, effect reported, studied in people and randomised / blinded because the record does not state it. We have no data on journal's citation record, times cited, citations per year, impact for its field and year, cited by studies here, still being cited, senior author's track record, institution's track record, multi-centre collaboration and free to read, so those were left out: it earned 21 of the 56 points we could judge it on, which is 38 out of 100.
