Do not ask the EEG technologist to interpret or explain your results. If there are issues regarding the EEG of immediate concern, the doctor will contact you for further testing or discuss the findings with you on the phone. How will I get my results?Īfter the technologist completes your study the doctor will review the study and discuss it with you at your next visit. This helps to determine the cause of any seizures. Do not forget to use the button to mark the time of your events. You will need to keep a diary with exact times to correlate behavior with events on the EEG. During this procedure, the EEG is recorded for a prolonged period,allowing you to have a comprehensive EEG at home. It is then translated into a complicated graph. The activity is amplified and recorded on the computer. The electrodes pick up very small changes in brain electrical activity. If the electrodes are moved, then the quality of the recording will be poor. The paste or glue is to keep the electrodes firmly in place. Small, non-invasive metal cups called electrodes (usually 16 to 32 in number) are pasted on the scalp, after careful measurement by a trained technologist. You will be held responsible for any damages.Īt the end of each 24 hour period you will return to the EEG lab to have the information downloaded to the computer for analysis. Do not attempt to adjust anything on the device and do not adjust the wires. Do no allow the box to get hit or banged against other objects. The ambulatory EEG is a very expensive (~$20,000) piece of equipment that allows us to monitor a 24 hour period of brain waves but allows you to continue with most of your daily activities. The doctor can see seizure activity as well as sleep stages during your EEG. It can tell us what may be causing your episodes and help with deciding the best treatment for you. Family and friends should follow your usual first aid or emergency procedures. If you have a seizure during the test, you should behave as you normally would during a seizure. The EEG only detects activity in the brain. No electricity is transferred to your brain. It records a graph of your brain waves.ĭigital analysis is a procedure that can give additional information about any problems that may be found.Īnalysis and examination of the data obtained allows your doctor to see one of the many ways that your brain functions.ĮEG is not a treatment of any kind. This test is performed to see how the different parts of your brain function.
Ambulatory eeg series#
The electroencephalograph is a machine that translates the electrical activity of the brain into a series of wavy lines (a graph) on a computer called the EEG record.Īn EEG measures the electrical activity of the brain, sometimes referred to as brain waves. This will facilitate comfortable placement of the electrodesĮEG is the abbreviation for electroencephalography. Do not leave any hair products in your hair and remove any braids or hair extensions.

Remember that the tops should button and be loose fitting. Most patients wear street clothes or a sweat suit during the day and warm pajamas and socks at night.

Sweat pants and a loose fitting top with buttons down the front are suggested. You should wear comfortable clothing while your ambulatory EEG is being performed. Please do not eat potato chips or other snack foods or chew gum, since this will interfere with the EEG - it generates a lot of “noise” on the graph which makes it impossible to detect anything else. This can be obtained over the counter at your local pharmacy. Benadryl 25 mg to 50 mg can be used for itching. Do not scratch your head with the electrodes in place. Sometimes, the electrodes can cause some itching to occur and you can take medication to help the itching. What will happen when I am set up for monitoring? Placement of the EEG wires for monitoringĮEG wires will be attached to your head with a special glue so that the electrodes will stay attached for several days. Ambulatory monitoring can help diagnose your seizure type and provides important information regarding the best treatment for your seizures. Ambulatory EEG monitoring enables your doctor to observe your EEG over a prolonged period of time. Epilepsy is a disease of the brain caused by abnormal electrical activity.
