At Las Vegas Neurology Center we use Videonystagmography (VNG) technologies for testing inner ear and central motor functions. VNG testing is considered the new standard for testing inner ear functions over Electronystagmography (ENG), because VNG measures the movements of the eyes directly through infrared cameras.


Transcranial Doppler (TCD) is an older technology that has been recently redefined to be of great use. This is a painless test in which the technician will use an ultrasound and gel to assess the arteries of the brain. The test takes anywhere from 30-50 minutes. It is noninvasive and simply measures blood flow in the arteries of the brain.  


Nerve conductions studies (NCS) and electromyography (EMG) are two separate, and very high-yield tests that are done to allow the physician to examine your nerve function and see how the nerve communicates with the muscles in your arms and/or legs. The NCS is done first and is followed by the EMG.


Evoked potentials are simple tests that measure the brain’s ability to sense basic items including touch, light, and sounds. Three main evoked potentials tests are done in our office. Visual Evoked Potentials (VEP) are done to assess the pathway from the eye to the part of the brain responsible for vision. Somatosensory Evoked Potentials (SSEP) assess the pathways of the nerves from the arms and legs to the spine then to the part of the brain that is responsible for touch sensation. Brainstem Auditory Evoked Responses (BAER) are done to allow the physician to assess the hearing pathway from the ear to the brain. 


What is an electroencephalogram? An EEG is a test used to measure the electrical activity of the brain. It is a painless examination. Our friendly technician will place simple electrodes on the surface of your scalp. The electrodes are held by a water-soluble gel. There are no needles involved.


Carotid ultrasound uses basic ultrasound technology to assess the arteries that supply blood to the brain. These are the carotid arteries, the vertebral arteries, and the basilar artery. This is a noninvasive, painless test that is done to check for narrowing, spasms, and even blockages of the arteries that provide the brain with its blood.


Botox has many uses in neurology, including migraine headaches, neck spasms, eye spasms, face spasms, muscle contractures, and more. This treatment is given by the physician. Our staff and physician will discuss the uses and administration of this therapy with you.


What is an ambulatory electroencephalogram (EEG)? An ambulatory EEG is essentially the same as the basic EEG except that the duration is longer. Sometimes the basic in-office EEG does not provide the information we are looking for based on your symptoms. The ambulatory EEG allows you to wear the EEG at home and live normally for 2 to 5 days. You will have a tiny, portable device attached to the leads to carry with you.
