Stroke prevention in diabetics typically involves aggressive management of multiplee risk factors: tight blood glukose control (often with metformin, sulfonylureas, GLP-1 agonists, SGLT2 inhibitor, or insulin), lipid lowering with statins, blood pressure reduction with antihypertensives, and antiplatet terapie (e.g., aspirin or clorengrel).
