Limiting sleep the night before an electroencephalography (EEG) can help to ensure that the brain activity can be more easily monitored during the test, especially if the purpose is to observe sleep patterns or to induce sleep during the EEG. Washing hair, fasting, or holding medications are not standard instructions for EEG preparation unless specifically advised by the healthcare provider for particular reasons.
