If you’re experiencing headaches, dizziness, seizures, confusion, stroke, loss of consciousness or have suffered a traumatic head injury, WakeMed offers a diagnostic test — an electroencephalogram (EEG) — that can give your doctor valuable information. In cases where the patient presents with seizures, there may be additional Long-Term Video Monitoring (LTVM).
An EEG test is used to record brain activity by strategically placing electrodes on a patient’s scalp. Performed as an outpatient procedure in our state-of-the-art neurodiagnostic lab, an EEG is an excellent diagnostic tool to show the effects from brain trauma, certain brain infections, brain function or loss of function in a particular region, as well as oxygen impairment to the brain.
Our team of neurodiagnostic experts collaborate to provide you whole-person care. We listen to you, answer your questions and develop a comprehensive plan suited for your individual needs.
EEG tests can be performed as routine, sleep-deprived, ambulatory or long-term with video monitoring. After the test, we’ll release results to the referring physician, who will review them with the patient.
In a routine EEG, the technologist strategically places electrodes on the patient’s scalp using a special paste. The patient may be asked to take a series of deep breaths and/or to stare briefly at a flashing bright strobe light. The patient remains awake and comfortable throughout the test but can also fall asleep. The test — including preparation, test and clean up — should take about 90 minutes.
This test uses the same procedures for a routine EEG, except that the patient needs to be sleep deprived for a specific amount of time, based on their physician’s direction. For example, adults may be asked to stay awake after midnight or wake early for the appointment. Children may need to stay awake up to two hours after their regular bedtime and be awakened two hours earlier than normal the day of testing with no naps on the way to the appointment or before the procedure. This can be helpful in diagnosing certain conditions that impact sleep patterns.
This runs for a day or more, based on the physician’s direction. The technologist strategically places electrodes on the patient’s scalp using a special glue-like substance, and then wraps the patient’s head, so the patient can move around freely.
The patient returns home and will be instructed to keep a diary of events while there. Once the testing is complete, the patient returns to the neurodiagnostic lab for electrode removal and to return the diary and equipment.
This test is helpful in diagnosing seizures in all age groups, especially in young patients. Here’s when the exam is typically recommended:
In an LTVM, electrical activity in the brain is recorded using EEG wires, and the patient is videotaped. Patients will be admitted to the hospital for one or more days. Either a parent or caregiver must stay with the child during the entire hospitalization.
Our testing is performed in our three WakeMed Neurodiagnostic Labs.
We welcome new patients. If you’d like to receive more information about EEG and LTVM testing at WakeMed, please call us at 919-350-3734. If you are a physician referring a patient, please call us at 919-350-7000.
We can also perform pediatric LTVM testing on infants and premature babies at WakeMed Children’s Hospital to gain a better understanding of brain activity.
WakeMed is proud to partner with many neurologists and neurosurgeons. In fact, they are the best in the business.
