Acquired aneurysmal subarachnoid hemorrhage (aSAH) is a type of stroke caused by bleeding in the space between the brain and the thin tissues that cover it. It is usually caused by a ruptured aneurysm, a weak or thin spot in a blood vessel in the brain that balloons out and fills with blood. The bleeding can cause severe headaches, confusion, and other neurological symptoms. Treatment typically involves surgery to repair the aneurysm and medications to reduce the risk of further bleeding.

Symptoms of Acquired aneurysmal subarachnoid hemorrhage include:

-Sudden, severe headache
-Nausea and vomiting
-Stiff neck
-Loss of consciousness
-Confusion
-Seizures
-Drowsiness
-Visual disturbances
-Loss of balance
-Weakness or Numbness in the face, arms, or legs
-Loss of bladder or bowel control

1. Ruptured intracranial aneurysm: Aneurysms are weak spots in the wall of an artery that can rupture and cause bleeding in the brain.

2. Head trauma: A severe blow to the head can cause a subarachnoid hemorrhage.

3. Arteriovenous malformation (AVM): An AVM is an abnormal connection between the arteries and veins in the brain that can cause bleeding.

4. Vascular abnormalities: Abnormalities in the blood vessels in the brain can lead to a subarachnoid hemorrhage.

5. Blood vessel inflammation: Inflammation of the blood vessels in the brain can cause a subarachnoid hemorrhage.

6. Use of certain medications: Certain medications, such as anticoagul

1. Surgery: Aneurysm clipping or coiling is the most common treatment for aneurysmal subarachnoid hemorrhage. Clipping involves placing a tiny metal clip at the base of the aneurysm to stop blood flow to it. Coiling involves inserting a catheter into the aneurysm and filling it with tiny metal coils to block the flow of blood.

2. Medication: Medications such as nimodipine, a calcium channel blocker, can be used to reduce the risk of vasospasm, a complication of aneurysmal subarachnoid hemorrhage.

3. Rehabilitation: Rehabilitation is an important part of recovery from aneurysmal subarachnoid hemorrhage. Physical, occupational, and speech therapy can help improve physical and cognitive functioning.

There is no cure for Acquired aneurysmal subarachnoid hemorrhage (SAH). Treatment typically involves medications to reduce the risk of re-bleeding, such as anti-hypertensives, anticoagulants, and antiplatelet agents. Surgery may be recommended to repair the aneurysm, and other treatments may include endovascular coiling or clipping.
