Routine EEG (electroencephalogram)
This painless test measures the electrical activity given off by your brain. The test involves pasting up to 27 small disc electrodes in various locations on your scalp. Recording times can take up to 2 hours. Clean up will be necessary after your test. We offer amenities to accommodate clean up with shampoo/conditioner, blow dryer, combs, and curling irons.
To prepare for an EEG, please do the following:
This test is similar to a regular EEG, as described above, except that you will be asked to achieve 4 fewer hours of normal sleep or as directed by your provider prior to your exam time. Do not eat or drink anything containing caffeine between midnight and the time of your test. A sleep-deprived EEG takes about 1-2 hours.
This test is similar to a regular EEG, as described above, except without video. You will complete your testing at home. Once your test is completed and equipment is returned, your neurologist will compare your brain waves to what is considered normal for your age.
Setup for the test takes approximately one hour and requires a technician pasting 25 small electrodes onto the surface of the scalp using a sticky, water-soluble paste. The wires are covered with netting and a bandana. The electrodes plug into a small recording unit called a headbox that is worn crossbody or in a small backpack. We ask you arrive in a shirt that either button downs or zips. Once wires are applied you will not be able to remove clothing over your head.
You will be given a diary at your appointment to help record descriptions of events at the times of any occurring spells. If you feel a symptom of an event (such as dizziness, light-headedness, faintness, seizures, shaking) you will be instructed to push the event marker and give a detailed description of the events. Diary entries should be made every hour indicating activities such as eating, taking medication, sleeping, watching TV, etc.
During the testing period:
You may do many quiet normal daily activities such as:
Please do not:
All equipment including EEG headbox, event marker, carrying case or backpack, and completed diaries must be returned. Your tech will go over all instructions at the time of your appointment.
