Hemorrhage means heavy bleeding. The space between the brain and the tissue that covers the brain is called the subarachnoid space. So this kind of hemorrhage is bleeding in that space just outside the brain.
When blood spills into this small space, it builds up and presses on the brain. This often causes sudden and severe head pain. Other symptoms sometimes include nausea and vomiting, neck pain, or vision problems. Some people pass out or have a seizure. But the most common symptom is what many people describe as "the worst headache of my life."
This hemorrhage is a type of stroke. Quick treatment is needed to prevent brain damage and death.
The problems caused by a subarachnoid hemorrhage depend on what part of the brain was affected and how much damage it caused. For example, there may be problems with movement, senses, speech, memory, thinking, or emotions. Stroke rehabilitation, which includes training and therapy, can help with recovery.
The goal of treatment is to prevent brain damage, more bleeding, and other serious problems. You will likely be in the hospital's intensive care unit, where your medical team can keep a close watch on you. They will work to control your blood pressure, manage pain, and watch for symptoms of brain damage.
You may have more tests to find out for sure that an aneurysm caused the bleeding. If you have an aneurysm, you may have a procedure or surgery to repair it. This can help prevent another bleeding episode.
Treatments to repair an aneurysm include:
You will need treatment even if your symptoms go away. This is because there is a good chance that the area will bleed again.
