PREPARATION FOR TESTING
1. Hair must be clean and dry, with no hair tonic, oil, gel, mousse, etc., and especially, no hair spray. If you wear braids, some of them may need to be undone. If you wear a hair‑weave, check with the technician prior to making an appointment.
2. Take your regular medicines, and eat your regular meals. Bring a list of your medications with you.
3. Do NOT drink any beverage with caffeine or alcohol in it for at least 24 hours prior to the test‑this includes coffee, tea, and most soft drinks. You may drink water, milk, fruit juices, or decaffeinated beverages.
4. If the doctor has ordered a sleep‑deprived EEG on you, be sure to get no more than 4 hours of sleep (1/2 your usual amount of sleep) the night before the test, so that you will be able to fall asleep during part of the test. If you feel that you will be too sleepy to get home on your own after so little sleep, be sure to bring someone with you who can help you get home.
1. Follow instructions I and 2 for EEG as above. You may have up to 2 caffeinated beverages or one alcoholic beverage the day prior to the test, but you should not have caffeine or alcohol on the day of the test, or during it. You do not need to be sleep‑deprived.
2. Wear a shirt or blouse that buttons up the front, as otherwise it will be quite difficult to take it off.
3. Wires are glued to your head, going to a soft collar worn around the neck, with a cable going from there to a tape‑recorder worn on a belt around the waist, which you wear home. You will look somewhat peculiar, so you may want to bring a hat or scarf, and possibly a coat.
4. The solution used to remove the glue is somewhat oily, so plan on going home and washing your hair, after having the wires removed on the second day.
Q‑EEG (Quantitative EEG):
1. Follow instructions I and 2 for EEG as above. (If you normally drink more than two alcoholic beverages per day, or five or more caffeinated beverages per day, you should stay off of alcohol and caffeine for 48 hours, to give them sufficient time to clear out of your body.) You should not be sleep‑derived, as you need to be awake and alert for this test.
2. As much as possible, you need to be off of all medications for this test, as many medications interfere with the testing and make it less useful. Check with your doctor as to which medications you should continue taking, and bring a list of medicines you've taken with you.
You need to be awake and alert for these tests. Medications do not affect the tests, unless they make you sleepy. For the VER, if you wear glasses or contact lens, bring them with you.
Do not drink alcohol for 24 hours prior to test. Certain antibiotics may affect the test‑if you are on antibiotics, tell technician prior to test.
Sensory Perception Testing (CPT or SPT): _______
Do not use any cream, lotions, oils, etc., on the skin‑these make it difficult to record. If you wear loose clothing for the SERs, you may not have to change into a patient gown. These tests are somewhat uncomfortable.
BEAM (Brain Electrical Activity Mapping):
This includes a regular EEG, Quantitative EEG, VER, BAER, and P300, with extensive quantitative, spectral, and brain‑mapping computer analysis of the various tests. Preparation is the same as for the Quantitative EEG.
AT (Autonomic Test):
This tests your autonomic nervous system, which controls many of your Involuntary functions, such as how high your blood pressure is, how fast your heart beats, sweating, breathing, etc. For this test, EKG electrodes are applied to the left and right collarbones and to the bottom of the rib cage on the left, and a blood pressure cuff goes on the left arm. You are asked to sit quietly, and then to do some deep breathing, valsalva maneuvers, and then stand up. (Valsalva for this you take a deep breath, hold it and bear down. Technologist will explain it further at the time of the test). The test takes about 30 minutes, and is not painful, but very peaceful and quiet. It is necessary to be able to get at the collarbones, waist and put a blood pressure cuff on, so dress appropriately. There is no preparation for this test.
Doppler ultrasound (a non-invasive test) is a test that uses sound waves to create images and sounds of your blood flow. This test can detect narrow or blocked arteries or ulcerated plaques. An ultrasound scan of the carotid arteries screens for buildup of fatty plaque - the leading cause of strokes. A hand-held probe placed against the skin emits sound waves. The sound waves bounce off the moving blood cells in the arteries and echo back to the probe. The echo is translated into an image that appears on a screen. The test involves no radiation and is harmless, there are no injections of contrast and gives important information about real-time physiology of the vascular systems going to the brain and the Circle of Willis.
You may be asked about your health. Your answers will help the sonographer.
During Doppler ultrsound, you may hear a "whoosing" noise. This is the sound of your blood flowing. You may also see tracings of your blood flow on a screen. The sonographer can answer your questions about the test. But only a doctor can explain the results.
