If you are experiencing headaches, dizziness, seizures, confusion, stroke loss of consciousness or have suffered a traumatic head injury, WakeMed offers a diagnostic test – an electroencephalogram – that can give your doctor valuable information about your problem. An EEG test is used to record brain activity from electrodes that are strategically placed on a patient’s scalp.
Performed as an outpatient procedure, an EEG is an excellent diagnostic tool used to show effects from trauma in the brain, certain brain infections, brain function or loss of function in a particular region, as well as oxygen impairment to the brain.
Learn what to expect from an electroencephalogram EEGs may be performed as routine, sleep deprived, ambulatory or long-term with video monitoring.
Routine EEG: Total test time (includes preparation, test, and clean-up) is approximately 90 minutes based on physician order.
Sleep-Deprived EEG: This test uses the same procedures for a routine EEG, except the patient needs to be sleep deprived based on their physician’s order. For example, adults must stay awake after midnight, and children must stay awake two hours later than regular bedtime and get up two hours earlier than normal prior to testing. The recording made during sleep is helpful in diagnosing certain conditions.
Long-Term Video Monitoring (LTVM):This test is the most accurate in diagnosing seizures in young patients. The exam is usually recommended when:
LTVM records the electrical activity in the brain while also videotaping the patient. Performed at WakeMed Raleigh Campus, patients are admitted to the hospital for one or more days. Parents or a caregiver must stay with the child during the entire hospitalization to assist with the test. This test is also performed on infants and premature babies to gain a better understanding of brain activity. Learn what to expect from a LTVM
Activating procedures like Hyperventilation and Photic stimulation, using a strobe light may be performed if necessary
The adult staying with the child will be responsible for pushing a button on the computer each time a seizure is observed or suspected. Additionally, the parent/caregiver will keep a log of each suspected seizure, including the symptoms and start and stop time of the event.
EEGs and LTVMs are performed in the WakeMed Neurodiagnostic Lab at our Raleigh campus, located on the 1st floor in the Medical Office Building.
