What Causes A Subarachnoid Hemorrhage?

Bleeding Disorders

Bleeding disorders are conditions that cause abnormalities in how the blood clots, and these disorders may raise an individual's risk of a subarachnoid hemorrhage. Most bleeding disorders are inherited, and some may develop in patients who have a low red blood cell count or vitamin K deficiency. The easy, excessive bleeding that characterizes bleeding disorders can also be a side effect of anticoagulants. Symptoms of bleeding abnormalities may include easy bruising, frequent nosebleeds, excessive bleeding after a minor cut, bleeding into the joints, and heavy menstrual periods. Doctors perform complete blood counts, bleeding time tests, and platelet aggregation tests to investigate bleeding problems. Depending on the exact cause of a patient's bleeding disorder, treatment options could include iron supplements, blood transfusions, topical treatments, or nasal sprays.
