A Multi‐domain Lifestyle Intervention does not Improve Health and Cognitive Outcomes Among APOE e4 Carriers after 4‐months

Alzheimer’s Disease (AD) currently affects 24 million individuals worldwide, this rate is expected to triple by 2050. The greatest genetic risk for AD is apolipoprotein E (ApoE; e4 allele carriers), e4 carriers typically exhibit abnormal regulation of lipoprotein metabolism. It is important to understand whether multi‐domain lifestyle interventions can mitigate cognitive decline and improve overall health in ApoEe4 carriers. Thus far, the data are mixed due to sample sizes and methodological limitations. Therefore, the purpose of this present investigation is to determine if a digital multi‐domain intervention (MDI) can improve health and cognitive outcomes in cognitively at‐risk e4 carriers over 4 months.
