Yes. It's possible.: There are two types of strokes. Hemorrhagic and Thromboembolic. Hemorrhagic strokes can occur with the use of blood thinners secondary to decreased effectiveness of clotting factors. Please visit the ER within 2 hours of suspicious onset of weakness or disorientation.

Yes, but good INR: Warfarin REDUCES the risk of stroke in certain conditions (atrial fibrillation) but it does NOT ELIMINATE it. There are medications which perform better than warfarin in risk reduction - talk to your doctor / cardiologist about that. The higher the INR, the lower the risk of stroke but the higher the risk of bleeding, so an INR 2-3 is targeted. It's impossible to keep it narrower than that 4 other
