What is an ambulatory electroencephalogram (EEG)?
An ambulatory EEG is essentially the same as the basic EEG except that the duration is longer. Sometimes the basic in-office EEG does not provide the information we are looking for based on your symptoms. The ambulatory EEG allows you to wear the EEG at home and live normally for 2 to 5 days. You will have a tiny, portable device attached to the leads to carry with you. This gives the physician a great deal of information about the electrical activity of your brain because the recording time is so long. Just like the basic EEG, the ambulatory EEG is painless and causes no harm. We will set up the ambulatory EEG electrodes in our office and then you will go home with it, live normally, and then return to our office. We will then upload all of the information the EEG recorded and review it fully.
How to prepare for an ambulatory EEG
Preparation for the ambulatory EEG is similar to that of the basic EEG. Electrodes will be placed on your scalp with a water-soluble gel by our friendly technician. Before coming in for the ambulatory EEG, we politely ask that you do the following:
Our staff will give you a date and time to come to the office to have our technician place the electrodes. This may take between 30 to 45 minutes to complete. After the electrodes are placed, your head will be wrapped to keep the electrodes in place so they don’t move and you get an accurate test. You will be told on what day and what time to come back to the office to have the electrodes removed and return the computer. Don’t forget to bring your event calendar as well.
