EEG Frequently Asked Questions

What is an EEG?

An EEG (electroencephalogram) is the gold standard test used by physicians to diagnose or rule out seizures/epilepsy. Routine EEG services can be completed by using a combination of on-site and remote neurodiagnostic personnel. INN offers EEG and cEEG/Neurotelemetry services and pride ourselves on providing results to improve your patients’ outcomes.

Why is an EEG Test Helpful?

An EEG test is helpful to diagnose and treat seizure disorders, to look for the cause of confusion, and to evaluate head injuries, tumors, infections, degenerative diseases, and metabolic disturbances that affect the brain. It is also used to evaluate sleep disorders and to investigate periods of unconsciousness.

Is an EEG Painful?

An EEG is not painful. Small button-like electrodes are placed in precise spots on the head. For most patients a combination of special paste and glue is used to ensure the electrodes stay in place. At the end of the EEG study a solution is used to remove the glue, and electrodes and paste are washed away with damp wash cloths.

What Does an EEG Show?

An EEG shows brain wave activity by using electrodes to record and pick up electrical signals from brain cells. When someone has an epileptic seizure, their brain activity changes. This change can be seen on the EEG.

Why is My Physician Ordering a Video EEG?

Your physician may order a video EEG in order to provide you with the best care. The video will allow viewing of the brainwave activity AND a video/audio recording simultaneously. A neurologist examines the EEG recording for abnormalities in the brain-wave pattern, which may reflect diseases of the nervous system.

Will My Family Members be Video Taped?

It is possible that a family member may be videotaped. The video and audio recording is continuous, so if a family member happens to walk in front of the video camera, they will be on the video briefly. However, the physicians are only interested in seeing the patient on video to capture clinically significant events.

How Are Results Reported?

EEG results are reported by the neurologist who reads the EEG everyday. The neurologists communicate with the primary care physician. The EEG is a part of a patient’s medical record, and upon request, can be obtained.
