WHAT YOU NEED TO KNOW:
What do I need to know about an ambulatory electroencephalogram (EEG)?
- An ambulatory EEG is a test that measures the electrical activity in your brain. The test may last 24 hours or more. The test will start in your healthcare provider's office and continue in your home. The discs and wires on your head will be connected to a recorder. The recorder is a small box that can be worn on your shoulder or across your waist. Your head may be wrapped with gauze or covered with a cap. The gauze or cap will help hold the discs and wires in place.
- You may need an ambulatory EEG to diagnose or monitor seizures or sleep disorders. An ambulatory EEG can help healthcare providers decide if treatment should be started, stopped, or changed. You may also need an ambulatory EEG before surgery for epilepsy. This will help your surgeon plan your surgery.
What do I need to do during an ambulatory EEG?
- Follow your normal routine as much as possible. Do not remove the gauze or cap or pull on the wires. Do not scratch your head. Do not play contact sports or do activities that could cause the discs to fall off.
- Keep a journal of your symptoms and activity during your EEG. This will help your healthcare provider compare the EEG recording to your symptoms or seizure activity. Ask a family member or caregiver to help you do the following:
- Write down your daily activities such as eating, or sleeping. Your healthcare provider may tell you to write down other activities such as watching TV.
- Write down your symptoms such as a headache, dizziness, or changes in your vision. Write down any other symptoms that your healthcare provider tells you to.
- Write down the details of your seizure. Tell your family or caregiver to press the event button on the recorder if you have a seizure. They should also write down the following information:
- The date and time of your seizure
- How long your seizure lasted
- Body movements and how you act during the seizure
- What you were doing before your seizure started
- How you felt before and after the seizure
- Do not get the EEG recorder wet. Do not shower or go swimming during your EEG. Water can damage the recorder. It is okay to take a sponge bath.
How can others keep me safe during a seizure?
Give the following instructions to family, friends, and coworkers:
- Do not panic.
- Gently guide me to the floor or a soft surface.
- Do not hold me down or put anything in my mouth.
- Place me on my side to help prevent me from swallowing saliva or vomit.
- Protect me from injury. Remove sharp or hard objects from the area surrounding me, or cushion my head.
- Loosen my clothing around the head and neck.
- Time how long my seizure lasts. Call 911 if my seizure lasts longer than 5 minutes or if I have a second seizure.
- Stay with me until my seizure ends. Let me rest until I am fully awake.
- Perform CPR if I stop breathing or you cannot feel my pulse.
- Do not give me anything to eat or drink until I am fully awake.
Call 911 or have someone else call for any of the following:
- Your seizure lasts longer than 5 minutes.
- You have trouble breathing or stop breathing.
- You cannot be woken after your seizure.
- You have more than 1 seizure before you are fully awake or aware.
- You have a seizure in water.
When should I seek immediate care?
