What drives the female-specific excess of microbleeds in APOE4 carriers independent of hypertension?

OPEN

E4 females show highest MB prevalence at 6 months with normal blood pressure, indicating sex-specific mechanisms beyond hypertension. The molecular basis for this APOE4-female interaction in cerebrovascular integrity remains unclear but could inform personalized AD risk assessment.
