Notes:
Although the intensity of anticoagulation documented at the time of the intracranial hemorrhage appeared to be within the range for their study, most had relatively high values (PTR?.5 or INR?.0). Therefore, although more data are needed, it appears that very elderly individuals are at increased risk for anticoagulant-associated brain hemorrhage, especially if excessively anticoagulated.
