Hi Annie,
Definitely check with your doctor about that.
Sleep deprivation can increase the chance of recording "epilepsy waves" during the test, as it's one of the most common seizure triggers. This practice helps enhance the diagnostic value of the EEG and may avoid more complex EEG tests.

May your EEG be an enlightening test!
