Barack and Michelle Obama did not adopt either of their two daughters. Perhaps you are thinking of Mr. Obama's 2008 opponent, John McCain-- he and his wife Cindy did adopt a lâ¦ittle girl from Bangladesh.
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. If the EEG is to be done during sleep, adults may not be allowed to sleep more than 4 or 5 hours the night before the test. Children may not be allowed to sleep for more than 5 to 7 hours the night before.
