A Guide to Neurodiagnostic Testing

Quality patient care through recording and study of the electrical activity of the brain and nervous system
Neurodiagnostics analyzes and monitors nervous system function to promote the effective treatment of neurological diseases and conditions. Technologists record electrical activity arising from the brain, spinal cord, and peripheral nerves using a variety of techniques and instruments.

Neurodiagnostic technologists prepare patients for procedures, obtain medical histories, record electrical potentials, calculate results, maintain equipment, and may work with specific treatments. They develop rapport with patients and comfort them during the recording procedure, which can last from 20 minutes [for a single nerve conduction study] to 8 hours for a sleep study, to multiple days admission for long term monitoring. Neurodiagnostic technologists 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. Considerable individual initiative, reasoning skill, and sound judgment are all expected of the electroneurodiagnostic professional.

The most common neurodiagnostic procedures are the electroencephalogram, long term monitoring, intraoperative neuromonitoring, the polysomnogram, evoked potential studies, and nerve conduction studies. The electroencephalogram [EEG] is the most frequently performed procedure.
