APOE ε4

The APOE ε4 variant is a genetic factor that significantly increases the risk of developing Alzheimer's disease and other neurological conditions. Studies have found that individuals with this variant are more susceptible to cognitive decline, particularly as they age, and there may be sex-specific interactions affecting cognitive impairment. Additionally, research indicates that APOE ε4 can influence the progression of synucleinopathy, a condition associated with Parkinson’s disease, and possibly contribute to glaucoma risk. Connections in health data show links between this genetic variant and lifestyle factors influencing cognitive function among older adults, as well as interactions involving neutrophils and microglia that drive cognitive impairment. While these findings provide valuable insights into the role of APOE ε4, more research is needed to fully understand its effects across different populations.
