A subarachnoid hemorrhage (SAH) is a type of stroke caused by bleeding into the space surrounding the brain, called the subarachnoid space. This space is filled with cerebrospinal fluid that cushions the brain. When bleeding occurs here, it can lead to serious brain damage, disability, or even death.
Types of Subarachnoid Hemorrhage
- Aneurysmal Subarachnoid Hemorrhage: Caused by the bursting of a brain aneurysm.
- Non-Aneurysmal Perimesencephalic Subarachnoid Hemorrhage: Bleeding around the brainstem not caused by an aneurysm.
- Traumatic Subarachnoid Hemorrhage: Caused by a head injury.
- Spontaneous Subarachnoid Hemorrhage: Bleeding that occurs without a known trigger.
Causes of Subarachnoid Hemorrhage
- Brain Aneurysm: A weak spot in a brain artery that bursts.
- Head Injury: Trauma to the head causing blood vessels to break.
- Arteriovenous Malformation (AVM): Abnormal connection between arteries and veins.
- Hypertension: High blood pressure that stresses blood vessels.
- Blood Thinners: Medications that increase bleeding risk.
- Smoking: Increases risk of aneurysms and bleeding.
- Excessive Alcohol Use: Weakens blood vessels.
- Drug Abuse: Especially stimulants like cocaine.
