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.
For shorter EEGs, you can expect it to take anywhere from 45 minutes to an hour to get the EEG set up, another hour for the test, and usually a quicker 15 or 30 minutes to take everything off.ou do not have to cut your child's hair before an EEG, but it is a good idea to wash it and not use any conditioners or products in their hair so the glue sticks better. Most EEGs are done in the hospital for an hour or two, but your doctor may order a 24 hour, 48 hour (or longer) EEG.
