Subarachnoid Hemorrhage – What is it, Symptoms and Treatments!

Subarachnoid Hemorrhage – What it is, Symptoms and Treatments of this condition. Also, Subarachnoid Hemorrhage is bleeding that occurs in the subarachnoid, which is the area between the brain and the tissues that cover the brain . The subarachnoid space is the space where the cerebrospinal fluid circulates, and is responsible for protecting the brain from injuries, serving as a cushion. A hemorrhage in this space can cause coma, paralysis and even death.

This condition can occur quickly, and is often the result of head trauma. The key to survival is prompt medical intervention. Call a doctor or 911 as soon as possible if you or someone you know has the symptoms of Subarachnoid Hemorrhage .

This potentially fatal condition is also rare. According to the Brain Aneurysm Foundation, Subarachnoid Hemorrhage accounts for between 0.01 and 0.08 percent of emergency room visits.

Causes of Subarachnoid Hemorrhage: Subarachnoid hemorrhage can occur spontaneously, or as a result of head trauma. Spontaneous Subarachnoid Hemorrhage is often related to cerebral aneurysms , which are abnormalities within the cerebral arteries.

The most common cause of Primary Subarachnoid Hemorrhage is a berry aneurysm . It’s called a berry aneurysm because it forms a cluster of sac pouches in a brain vessel that looks like a cluster of berries. These aneurysms swell and weaken the artery walls over time.

When an aneurysm erupts, it bleeds quickly and forms a clot. This condition is responsible for most cases of Subarachnoid Hemorrhage . Aneurysmal hemorrhage can occur at any age, but is most common between the ages of 40 and 65.

Brain aneurysms are more common in women, smokers and people with high blood pressure. In some cases, trauma to the brain during an injury can cause aneurysms and result in a Subarachnoid Hemorrhage .

Other Causes of Subarachnoid Hemorrhage Include:

  • Bleeding from an arteriovenous malformation (AVM);
  • Bleeding disorders;
  • Use of blood thinners;

A serious head injury, such as one that occurs in a car accident or when an older person falls and hits their head, can also lead to a  Subarachnoid Hemorrhage .

Symptoms of Subarachnoid Hemorrhage: When Subarachnoid Hemorrhage develops, it has several symptoms. The main symptom is a sudden, severe headache, which is most intense at the base of the skull. It is often described as the worst headache people have ever experienced. Some people may even feel a popping sensation in their head before the bleeding starts.

You Can Also Have:

  • Neck ache;
  • Numbness throughout your body;
  • Pain in the shoulder;
  • seizures;
  • Confusion;
  • Irritability;
  • Light sensitivity;
  • Decreased vision;
  • Double vision;
  • nausea ;
  • vomiting ;
  • Fast loss of alert.

Symptoms of SAH come on suddenly, and you can quickly lose consciousness. Seek emergency medical attention immediately if you experience any of these symptoms combined with a severe headache.

Subarachnoid Hemorrhage Risk Factors: Subarachnoid hemorrhage  can occur at any age, and some people are even born with brain aneurysms that can lead to this condition.

According to the Internet Stroke Center, women are more likely than men to develop brain aneurysms, and therefore Subarachnoid Hemorrhage Smoking and high blood pressure can also increase your risk of developing an aneurysm . Drug use, particularly methamphetamine and cocaine, dramatically increases the risk of not only developing an aneurysm, but subarachnoid hemorrhage .

It is estimated that one in 50 people have an undestroyed aneurysm in the United States. You should speak to your doctor about your risk if you have a history of brain aneurysms .

If you have aneurysms , it is important that you see your doctor regularly to determine your risk of bleeding – before Subarachnoid Hemorrhage develops .

Diagnoses of Subarachnoid Hemorrhage: Subarachnoid Hemorrhage is often detected during a physical exam. Your doctor may notice that you have stiff neck and vision problems. The history of the sudden headache of your life also makes Subarachnoid Hemorrhage more likely.

This combination usually leads to a diagnosis of Subarachnoid Hemorrhage . You will need further tests to find out the severity of the bleeding so you can get proper treatment.

First, your doctor may perform 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:

  • MRI, which uses radio waves to obtain clear, detailed images of the brain ;
  • Cerebral angiography, which uses an X-ray and injected ink to detect blood flow in the brain ;
  • Transcranial ultrasound, which detects blood flow in the arteries of the brain ;
  • Lumbar puncture to check whether blood cells are found in the cerebrospinal fluid.

This condition is often misdiagnosed because 73 percent of people do not get scans.

Subarachnoid Hemorrhage Treatments: Prompt treatment is important to save your life and reduce the possibility and extent of brain damage. Bleeding and pressure can build up in the brain , leading to coma and further brain damage.

This pressure needs to be relieved by medication or a procedure to drain some of the cerebrospinal fluid. Second, the cause of the bleeding needs to be identified and treated, as rebleeds from the same aneurysm can often occur without treatment. Surgery is performed to cut, or close, the aneurysm and stop future bleeding.

If your aneurysm is being cut, a craniotomy is performed and the aneurysm is closed. A craniotomy involves opening the skull to expose the area of ​​involvement. A technique called endovascular coiling can also be used to reduce the risk of further bleeding.

If Subarachnoid Hemorrhage causes a coma, treatment will include adequate life support with artificial ventilation, securing the airway, and placing a drainage tube in the brain to relieve pressure.

If you do not lose awareness of Subarachnoid Hemorrhage , you will still receive strict instructions to prevent post-treatment coma. Bed rest is standard for people recovering from this condition. Your doctor will also ask you to refrain from straining your body or bending over. These actions can increase the pressure on your brain .

  • Your doctor may prescribe medication for:
  • Regulate blood pressure with medication through an IV;
  • Prevent arterial spasms with nimodipine;
  • Relieve severe headaches with pain relievers and anti-anxiety medications.
