Neurodiagnostics analyzes and monitors nervous system function to promote the effective treatment of neurological diseases and conditions.
Neurodiagnostic technologists record electrical activity arising from the brain, spinal cord, and peripheral nerves using a variety of techniques and instruments. This involves preparing patients for procedures, obtaining medical histories, recording electrical potentials, calculating results, and maintaining equipment. Technologists may work with specific treatments. Neurodiagnostic technologists are trained to understand neurophysiology and recognize normal and abnormal electrical activity. They act as eyes and ears for specially trained doctors who later review and interpret the data.
The Electroencephalogram [EEG] is a recording of the on-going electrical activity of the brain. An EEG is used to assist in the diagnosis of epilepsy and a variety of neurological symptoms. EEGs also are used to evaluate the effects of head trauma or the consequences of severe infectious disease. EEG information can help doctors determine medical and surgical treatment of epilepsy. In conducting an EEG, highly sensitive monitoring equipment records the activity through electrodes that are placed at measured intervals on a patient’s scalp. The test is not painful. The test itself usually takes about 90 minutes and the principal role of the patient is simply to remain still, relaxed and comfortable.
Evoked Potentials [EP] – Record electrical activity in response to stimulation
Evoked Potentials [EP] are recordings of electrical activity from the brain, spinal nerves, or sensory receptors in response to specific external stimulation. Evoked potentials are helpful in evaluating a number of different neurological problems, including spinal cord injuries, hearing loss, blurred vision and blind spots, acoustic neuroma, and optic neuritis. Evoked potentials are performed using either earphones to stimulate the hearing pathway, a checkerboard pattern on a television screen to stimulate the visual pathway, or a small electrical current to stimulate a nerve in the arm or leg.
We offer testing on all ages of patients both in the hospital and on an outpatient basis. Pediatric EEG interpretations are done in cooperation with Seattle Childrens Hospital and Swedish Medical Center. Older children and adult interpretations are done by Kadlec Neuroscience Neurologists.
