Neurophysiology plays a crucial role in diagnosing and managing disorders of the nervous system. At our practice, we offer advanced diagnostic testing including Electroencephalography (EEG), Electromyography (EMG), Nerve Conduction Velocity (NCV), evoked potentials, studies, and Prolonged Video EEG Monitoring. These tests help us assess brain activity, muscle function, and nerve health—essential for evaluating conditions such as seizures, epilepsy, neuropathy, carpal tunnel syndrome, and radiculopathy. Our board-certified neurologists perform each study with precision and care, using the latest technology to deliver accurate results and guide personalized treatment plans. We also offer at-home video EEG monitoring, giving patients the comfort and convenience of undergoing long-term brain activity recording in their own environment. This approach helps capture more natural behaviors and sleep patterns—without the need for a hospital stay.
Electrodiagnostic Medicine Q & A
An EEG records electrical activity in the brain and is commonly used to evaluate seizures, epilepsy, and other neurological conditions. It’s a painless, non-invasive test that helps detect abnormal brain wave patterns.
Prolonged Video EEG involves continuous brain wave monitoring paired with video recording over several hours to days. It is especially helpful in diagnosing seizure disorders and differentiating them from other events like fainting or movement disorders. We offer this service both in-office and as an at-home study, so patients can stay in a familiar setting while we gather high-quality diagnostic data.
EMG assesses muscle activity by recording electrical signals during rest and movement. NCV measures how quickly nerves transmit electrical impulses. These tests are often performed together to evaluate nerve and muscle function.
Evoked potentials are noninvasive tests that measure the brain's electrical responses to specific sensory stimuli—such as visual patterns, sounds, or touch. They help assess the integrity and speed of nerve signal transmission from the sensory organs to the brain. These tests are particularly useful for detecting subtle or early damage in the nervous system that may not yet cause noticeable symptoms. Healthcare providers often use evoked potentials to aid in diagnosing conditions like multiple sclerosis, optic neuritis, and spinal cord disorders, as well as to monitor nerve function during certain surgeries.
Evoked potential tests are valuable tools in diagnosing and monitoring various neurological conditions, including:

Multiple Sclerosis (MS):
EPs can detect slowed nerve conduction indicative of demyelination, aiding in early diagnosis.
Optic Neuritis:
VEPs help assess damage to the optic nerve, often associated with MS.

Acoustic Neuromas:
BAERs can identify tumors affecting the auditory nerve.
Spinal Cord Injuries:
SSEPs assist in evaluating the extent of spinal cord damage.

Intraoperative Monitoring:
EPs are used during surgeries to monitor the integrity of neural pathways, reducing the risk of postoperative neurological deficits.
These tests are generally safe, painless, and provide critical information that complements other diagnostic tools like MRI scans.

EEG and video EEG are painless. EMG and NCV may cause mild discomfort, such as brief muscle twitches or tingling sensations, but they are generally well tolerated.
For EEG or video EEG, arrive with clean, product-free hair and avoid caffeine beforehand. For EMG/NCV, wear loose, comfortable clothing to allow access to your arms or legs. We’ll provide specific instructions before your appointment.
Routine EEGs take about 30–60 minutes. EMG/NCV studies can take 45–90 minutes depending on the complexity. At-home video EEG monitoring usually lasts between 24 to 72 hours, depending on your provider’s recommendation. Most patients can resume normal activities immediately after testing.
