The test itself will take about 30-60 minutes. Placing the electrodes usually takes 20 minutes, but can take up to an hour, so the entire procedure may take about one to 2 hours. If you have an ambulatory EEG, brain activity is recorded for 24 hours or more.
Some EEG tests require that you sleep through the procedure and some do not. The night before, adults may not be allowed to sleep more than four or five hours, and children not more than five to seven hours, if the EEG is to be performed while the patient is sleeping.ome EEG tests require that you sleep through the procedure and some do not.
