AANEM - Accredited Laboratory

What is Neurodiagnostics?

Neurodiagnostics is a state-of-the-art diagnostic testing facility equipped with the latest technology for evaluation of neuromuscular disorders. All diagnostic studies are interpreted by board certified neurologists or neuroradiologists with specific training covering areas of testing. Quality standards are equal to or greater than those recommended by the professional societies. Neurodiagnostics is available not only to neurologists, but also to the general practitioner of the medical and chiropractic communities.

Why a Neurodiagnostic Center?

The concept evolved in response to the increasing demand for easy and cost effective access to neurodiagnostic testing. Neurodiagnostics gives you the freedom to guide through a comprehensive evaluation at one convenient location. Because we are a dedicated testing center, Neurodiagnostics can provide the highest quality of diagnostic testing.

The facility achieved accreditation by the Intersocietal Commission for the Accreditation of Vascular Laboratories (ICAVL). Click here to read more »


Digital Electroencephalogram (EEG)

An EEG is a recording of the ongoing electrical activity of the brain, which is used in the diagnosis of epilepsy and many other neurological symptoms.

24 Hour Ambulatory Digital Electroencephalogram (EEG)

(48 hour also available) This test records electrical activity of the brain. It is worn home and then removed the next day. Being much longer than a standard EEG, this test can help document nocturnal seizures and other events that may indicate seizures.


Electromyogram/Nerve Conduction Studies (EMG-NCS)

An EMG is a recording of the electrical activity in the muscles. It is performed to discover the cause of: Muscle Weakness, Muscle Spasms, Paralysis, Pain in the Arms, Hands and Legs.


Visual Evoked Potential (VEP)

A checkerboard pattern on a television screen will stimulate the visual pathway of the brain. This test can help determine Optic Neuritis and Demyelinating diseases (MS).

Brainstem Auditory Evoked Potential (BAEP)

Earphones are used to stimulate the auditory pathway to the brain. It will identify abnormalities of the inner ear, brainstem, and/or the auditory pathways of the brain.

Otoacoustic Emissions (OAE)

An OAE is an objective hearing screening to determine if a further comprehensive hearing evaluation is indicated, it is also used as a guideline in determining thresholds for BAEP.

Somatosensory Evoked Potential (SEP)

A small electrical current is used to stimulate a nerve in an arm and/or leg. It will identify abnormalities which interfere with the travel of the stimulus over the peripheral nerves and/or spinal cord.


Carotid Duplex

This test is an evaluation of the carotid arteries which supply blood to the brain. This test can detect narrowing and/or blockage of these blood vessels.

Bubble Study / Emboli Detection

This will determine if a patent foramen ovale (PFO) is present in the heart by listening for bubbles in the middle cerebral or vertebral arteries.

Transcranial Doppler (TCD)

This test assesses the speed of the blood flow in the major arteries of the brain. The assessment of blood flow helps to determine whether there is a narrowing, blockage or malformation of the arteries of the brain.


The autonomic nervous system testing measures the heart rate, respiration and blood pressure in sitting and standing. There are two breathing challenges during the test to measure the balance between the sympathetic and parasympathetic branches of the autonomic nervous system.


Video Nystagmography (VNG)

This test is designed to study the inner ear and central nervous system through the recording of eye movements.


Liberatory/Epley Maneuvers

The VNG can determine if an Epley or Liberatory Maneuver is recommended. These are simple treatments for Benign Paroxysmal Positional Vertigo (BPPV)

Computerized Dynamic Posturography (CDP)

Posturography measures the systems that control your equilibrium. Your ability to maintain balance depends on information received from the inner ear, vision, and the somatosensory nerves. By measuring your center of gravity, sheer and sway, the test can determine what systems your brain is using for balance. Motor control is evaluated as well as adaption.

Vestibular Autorotation Test (VAT)

The vestibular ocular reflex (VOR) is the system that controls eye movement with the inner ear. VAT measures both distance and timing to determine the function of the VOR.


NeuroTrax assists to better educate patients on the importance of Brain Health and screening.

NeuroTrax has a user-friendly and scientifically-validated cognitive assessment tool called Mindstreams that is used widely by physicians and psychologists to help diagnose disorders of brain function. The tests are done on the computer and even older adults with no computer experience can utilize it. The scores are compared to a database of healthy individuals, so that the report which is generated at the end of a NeuroTrax testing session informs how the patient scored compared to people of similar age and educational level.

MindStreams® tests represent a synthesis of well-established principles and cutting edge developments in the fields of cognitive psychology, neuropsychology, cognitive neurology, and cognitive neuroscience, containing tests for memory, attention, executive function, visual spatial processing, verbal skills, information processing speed, and cognitive motor skills. The tests that comprise the MindStreams® cognitive assessment batteries have been utilized in over 159 research studies that have resulted in more than 100 unique publications supporting their validity and usability, including 46 full-length peer-reviewed research articles.
