Subarachnoid Hemorrhage

 Subarachnoid Hemorrhage

Symptoms of SAH

 The main symptom is a sudden, severe headache, which is more intense at the base of the skull. Some people may even feel a popping sensation in their head before the hemorrhage begins.
You may also have:
  • neck pain
  • numbness throughout your body
  • shoulder pain
  • seizures
  • confusion
  • irritability
  • sensitivity to light
  • decreased vision
  • nausea
  • vomiting
  • rapid loss of alertness
  • Diagnosing SAH
     Your doctor may notice that you have a stiff neck and vision problems. This combination often leads to a diagnosis of SAH. You’ll need more testing to find out the severity of the hemorrhage so that you can get proper treatment.
    First, your doctor may conduct a CT scan of the head to look for bleeding in your skull. If the results are inconclusive, the doctor may use a contrast dye during the procedure.
    Other tests include:
    • an MRI scan, which uses radio waves to get clear, detailed images of the brain
    • a cerebral angiography, which uses an X-ray and injected dye to detect blood flow in the brain
    • a transcranial ultrasound, which detects blood flow in the arteries within the brain
