Neurodiagnostics assists physicians in the diagnosis of conditions that affect the brain and spinal cord. These studies and recordings of activity in the brain and nervous system determine if they are functioning correctly. Registered Technologists perform all studies.
An EEG records the electrical activity of the brain. Sensitive monitoring equipment records the activity through electrodes placed on the patient's scalp. EEGs assist physicians in the diagnosis of a variety of neurological problems from headaches and dizziness to seizure disorders, strokes, and degenerative brain disease. The EEG is also used to look for organic causes of psychiatric symptoms and disabilities in children and to determine irreversible brain death.
Evoked Potential (EP)
The EP records electrical activity from the brain, spinal nerves, or sensory receptors as they respond to stimulation introduced as part of the test. How long the response takes helps evaluate a number of different problems, including spinal cord injuries and hearing loss.
Neurodiagnostics Intraoperative Monitoring
Neurodiagnostics monitoring may be used during some types of surgery, giving the surgeon additional information about brain and nerve function during the operation. Evoked potential and Electromyography monitoring may be used during neurosurgery or orthopedic surgery, to help evaluate the nerve pathways of the area being operated on.
Newborn Hearing Screening
Neurodiagnostics tests the hearing of every baby born at St. Vincent Healthcare. Auditory pathway studies help identify hearing problems early.
Diagnosing Sleep Disorders
Polysomnographic technologists use a combination of neurodiagnostic and physiological techniques to monitor a patient's sleep during a night in the St. Vincent Sleep Center. Recording and studying brain and nerve activity, breathing patterns, and all other body activity help physicians diagnose and treat sleep disorders such as insomnia, sleep apnea, restless leg syndrome, and narcolepsy.
