MedicalResearch.com: What is the background for this study? What are the main findings?
Response: The epsilon(ε) 4 allele of the Apolipoprotein E (APOE) gene increases risk for Alzheimer’s disease (AD) and intracerebral hemorrhage (ICH).
In both diseases, it is believed to increase risk through the deposition of beta-amyloid within the brain and blood vessels, respectively. The effect of APOE ε4 on both AD and ICH risk changes across populations, for unclear reasons.
In our study, we confirmed the role of APOE ε4 for ICH risk in whites and found that the risk-increasing effect of the 4 allele is demonstrable in Hispanics only when balancing out the effect of hypertension.
