Can an INR elevated by warafin cause a seizure?

An elevated INR (International Normalized Ratio) due to warfarin can indicate an increased risk of bleeding, particularly intracranial hemorrhage, which could potentially lead to seizures. However, warfarin itself does not directly cause seizures. If a seizure occurs in a patient on warfarin, it may be related to complications from bleeding rather than the anticoagulant effect itself. Monitoring INR levels is crucial to prevent such complications.
