EEG & Neurodiagnostics Services

The Neurodiagnostics Lab provides inpatient and outpatient services for the evaluation and diagnosis of central and peripheral nervous system disorders. Certified neurodiagnostics technologists perform many types of neurophysiologic exams on inpatients and outpatients, and sub-specialized neurologists oversee the service. The service also provides monitoring during surgeries to help assess and protect the structural integrity of the nervous system.

The Neurodiagnostics Lab provides specialized procedures such as routine, extended, sleep deprived electroencephalography (EEG) and bedside continuous long-term video electroencephalography (VLTM) as well as continuous brain wave monitoring on acutely hospitalized patients. Hoag is one of the few hospitals in Orange County that provides this 24/7 inpatient EEG service, having established a unique application (BraiNet) protocol utilizing the entire hospital team, including our excellent nursing staff.

Other services requested by our community for various specialized neurological diagnoses include brain stem auditory evoked potentials (BAEP), somatosensory evoked potentials (SSEP) and visual evoked potentials (VEP). Board certified and eligible physicians with subspecialty training in nerve conduction studies (NCV) and electromyography (EMG) testing perform studies for our community in Newport Beach.

A vigorous Epilepsy Program is staffed by epilepsy monitoring technologists that perform 24/7 direct patient observation in the Epilepsy Monitoring Unit (EMU); with administrative staff providing oversight and education for Movement Disorders, Spine, MS, Headache, Stroke and in-house support for our neurohospitalists.

Team

The Neurodiagnostic Lab team is led by Dr. Jason Muir, Chief of Service Clinical Neurophysiology. He is board certified in Neurology, Clinical Neurophysiology and Sleep Medicine. The team includes the Newport Neurohospitalists Medical Group, EEG techs, and specialty specific inpatient nursing staff.

In the year 2018, outpatient EEG services expanded to the Hoag Hospital Sand Canyon site in Irvine. Increased community utilization was apparent as we performed 60 studies since opening in mid-2018 where our lab exclusively provides routine, extended and sleep deprived EEG services.

IONM Intraoperative Neurophysiologic Monitoring

As mentioned, intraoperative neurophysiologic monitoring provides surgeons with immediate data on the structural and functional integrity of the nervous system when patients are under anesthesia. Our surgeons incorporate the acquired data from these techniques during surgery to assure the utmost safety. Some of the surgeries that benefit from intraoperative neurophysiologic monitoring are brain surgery, orthopedic and spine surgery, and surgery for throat and larynx disorders.
