Ambulatory EEG

An ambulatory EEG usually tests for epileptic seizure activity over a certain period of time. Electrodes are glued to the scalp and the patient is either observed for a certain amount of time or is sent home to go about their normal daily activities with a device that records brain activity for the next 24 hours. Then the patient returns the next day to have the electrodes removed, and the data is analyzed.

Ambulatory EEG is a great way to rule out epileptic seizures but it will most likely not show partial seizures or non-epileptic seizures. It will also not show irregularities in your brain wave activity that something like a Quantitative EEG or Q-EEG will pick up.
