Electroencephalography (Ambulatory and Routine)

EEG is a technique that measures the electrical activity of the brain. It records brain waves to determine if there are any signs of abnormal electrical activity in the brain. EEG is useful in diagnosing various conditions such as seizures, fainting spells, blackout spells, confusion, amnesia, and memory lapses. A routine EEG is conducted in the office, where the brain waves are recorded for 30 minutes. On the other hand, an ambulatory EEG requires monitoring the patient for 48 or 72 hours, depending on the clinical evaluation. The procedure involves placing small surface electrodes on the scalp or head, which are then connected to a recording device. In an ambulatory EEG, the patient carries the portable recording device home and the recording continues as long as the electrodes are not dislodged. When the patient returns, a technician removes the electrodes and downloads the data for analysis. Neuro Spine & Pain Center's Doctors will review the results with you during your follow-up visit.

Why would your doctor recommend an ambulatory EEG?

Since the electrical activity of your brain can change frequently, routine EEGs only measure the activity over a brief period, typically a few minutes. In such cases, our neurologist at the Neuro Spine & Pain Center might recommend an ambulatory EEG that can evaluate your brain waves over a few days. This procedure allows your physician to monitor your brain waves during both wakefulness and sleep, offering a more comprehensive picture of your brain's electrical activity.

Cases where epilepsy or nonepileptic seizures need to be diagnosed or studied, your physician may suggest an ambulatory EEG as an effective solution.

Studying your symptoms during your daily routine can be beneficial, as it allows for observation of any triggers for your symptoms that may occur during your regular activities.

How to prepare for an ambulatory EEG

The first step is to reach for your appointment with clean and dry hair. Make sure there are no oil or heavy products on hair.

Next, you need to wear comfortable clothing. A button-down shirt and/or a tank top is ideal to make things easier when the physician hooks up electrodes.

You should plan on eating and sleeping as you normally. Normal food routine can be maintained before, during and after the testing.

It is suggested to take your prescribed medication(s) as usual, unless physician instructs you otherwise.
