What is a subdural hematoma?
A person with a subdural hematoma has a collection of blood between the brain and the thick lining that covers the brain. This thick lining is called the dura. Blood vessels lie between the brain and the dura. A subdural hematoma can form if the blood vessels are torn. The collection of blood places pressure against the brain, which causes the brain to malfunction. Most subdural hematomas are caused by head injuries.

What are the symptoms of a subdural hematoma?
Symptoms of a subdural hematoma include headache, nausea, vomiting, memory loss, confusion, difficulty speaking, difficulty walking, loss of coordination, arm weakness or numbness, leg weakness or numbness, loss of consciousness, and seizures.

How does the doctor treat a subdural hematoma?
Treatment for a subdural hematoma includes medications that reduce brain swelling, and surgery to remove the blood from around the brain.
