My son was sent for an EEG which came back normal. He was not told anything about not having any caffeine. His doctor has now sent him for a sleep deprived EEG and was told not to drink any caffeine. I'm curious....does the caffeine interfere with the actual test, or is it because they don't want it to keep you up during the test (I know they want him to sleep during the test).
The reason I ask is because we stayed up all night, and then without thinking he drank a beverage three hours prior to the test. We are having difficulty finding out if it had caffeine in it or not. The bottle did not say caffeine free, but did not say contains caffeine. He went for the test anyway - but, I'm wondering if the caffeine effects the actual test or not. He was able to fall sleep during the test.
Does anyone know for sure why caffeine is supposed to be restricted for this test?
