Idiopathic Intracranial Hypertension

WHAT YOU NEED TO KNOW:

IIH is a condition that causes the pressure inside your skull to be higher than normal for no known reason. IIH can seem like a brain tumor, but no tumor is found. IIH is most common in obese women who are of childbearing age.

WHILE YOU ARE HERE:

Informed consent

is a legal document that explains the tests, treatments, or procedures that you may need. Informed consent means you understand what will be done and can make decisions about what you want. You give your permission when you sign the consent form. You can have someone sign this form for you if you are not able to sign it. You have the right to understand your medical care in words you know. Before you sign the consent form, understand the risks and benefits of what will be done. Make sure all your questions are answered.

Medicines:

  • Migraine medicine may help decrease how much CSF you produce. This will help relieve pressure in your skull.
  • NSAIDs decrease swelling, pain, and fever.
  • Acetaminophen decreases pain.
  • Diuretics help decrease extra fluid that collects in your body. This will help lower the pressure in your skull. Diuretics are often called water pills. You may urinate more often when you take this medicine.
  • Pain medicine may be given. Do not wait until the pain is severe before you ask for more medicine.

Tests:

  • An eye exam is used to check for vision problems that may be a sign of IIH. Your healthcare provider will check your vision and examine your eyes. He or she may dilate the pupil and use a microscope with a strong light to look into your eyes. He or she may use a dye and take pictures of the inside of your eyes. The dye helps the blood vessels in your eyes show up better.
  • A neurological exam is used to check how your pupils react to light. Healthcare providers may check your memory, your hand grasp, and your balance.
  • CT or MRI pictures of your head may show fluid buildup and other problems. You may be given contrast liquid before the pictures are taken to help healthcare providers see the pictures better. Tell the healthcare provider if you have ever had an allergic reaction to contrast liquid. Do not enter the MRI room with anything metal. Metal can cause serious injury. Tell the healthcare provider if you have any metal in or on your body.
  • Lumbar puncture is a procedure to check the pressure inside your skull. A needle is inserted in your back and into the spinal canal. CSF may be collected and sent to a lab for tests. Healthcare providers may also drain CSF to relieve pressure and ease your headache.

Treatment:

  • Optic nerve sheath surgery allows extra CSF to drain and relieve eye pressure. A small opening is made in the sheath (cover) around the optic nerve.
  • A spinal fluid shunt (passageway) may be placed your brain or spinal cord to drain extra CSF into another area of the body. This helps relieve pressure in your skull.

RISKS:

Even with treatment, your symptoms may return. Without treatment, the pressure in your skull may continue to increase. This can cause severe headaches. Your vision may get worse and you may go blind.
