METHODS In a survey of 425 adults ≥50 years old, we assessed the willingness for a hypothetical epigenetic test, implementation preferences, reactions to a high‐risk result, behavior‐change intentions, and reasons for not testing using multivariable models. RESULTS Overall, 82.1% showed a willingness. Health literacy (odds ratio [OR] = 2.61) and Alzheimer's disease (AD) concern (OR = 2.06) increased that willingness; doctor dependence decreased it (OR = 0.62). The top drivers were perceived to be accuracy and speed. The preferred modality was a combination of biomarker and cognitive over biomarker‐only. Intended changes prioritized alcohol reduction, then diet, exercise, cognitive activity. Risk worry and insurance concerns exceeded stigma; higher literacy related to lower stigma, and epigenetics familiarity and AD worry related to higher insurance concern. The reasons for not testing were data privacy/accuracy concerns, logistics/costs, and needles.

Therefore, this article systematically reviews the synergistic mechanisms of microglia and the complement system in physiological synaptic pruning. Additionally, the dynamic evolution of the complement–immune network during disease progression is analyzed, and the amplifying effect of genetic factors on the spatial heterogeneity of synaptic pruning is explored.
