Services | NEUROLOGY

NEUROLOGY is a medical specialty dealing with disorders of the nervous system. Specifically, it deals with the diagnosis and treatment of all categories of disease involving the central, peripheral, and autonomic nervous systems, including their coverings, blood vessels, and all effector tissue, such as muscle.

Radiology

"Radiology is the science which deals with the use of radiant energy for the diagnosis and treatment of a disease. A minimally invasive form of medicare, it allows the doctor to study a patient's internal system, without making any cuts on the

Electroencephalogram (EEG)

An electroencephalogram (EEG) is a test that measures and records the electrical activity of your brain.Your brain cells communicate via electrical impulses and are active all the time, even when you're asleep. This activity shows up as wavy lines on an EEG recording.

Preparations

Electromyogram (EMG) and Nerve Conduction Studies (NCV)

An electromyogram (EMG) measures the electrical activity of muscles at rest and during contraction. Nerve conduction studies measure how well and how fast the nerves can send electrical signals. Nerves control the muscles in the body by electrical signals (impulses), and these impulses make the muscles react in specific ways. Nerve and muscle disorders cause the muscles to react in abnormal ways.

RNST

Repetitive nerve stimulation is a variant of the nerve conduction study where electrical stimulation is delivered to a motor nerve repeatedly several times per second. By observing the change in the muscle electrical response (CMAP) after several stimulations, a physician can assess for the presence of a neuromuscular junction disease, and differentiate between presynaptic and postsynaptic conditions.

Repetitive nerve stimulation is used to diagnose neuromuscular junction (NMJ) disorders, the most common of which is myasthenia gravis. A decremental response (a smaller and smaller muscle response with each repetitive stimulus) is abnormal and indicates NMJ dysfunction. This can be further confirmed if the response normalizes after administration of edrophonium or neostigmine.

Stimulation of a motor neuron causes it to release acetylcholine, which is stored up in vesicles at the axon terminal. The acetylcholine binds to nicotinic receptors on the muscle fiber, which open sodium channels and depolarizes the muscle cell.

BAER

A brainstem auditory evoked response (BAER) test measures how your brain processes the sounds you hear. The BAER test records your brainwaves in response to clicks or other audio tones that are played for you. The test is also called a brainstem auditory evoked potentials (BAEP) or auditory brainstem response (ABR) test.

A BAER test can help to diagnose hearing loss and nervous system disorders, especially in newborns, young children, and others who may not be able to participate in a standard hearing test.

BAER tests are often administered to canines and are the only scientifically reliable way to test a dog’s ability to hear with one or both ears.


VEP

Visual evoked potential (VEP) is a highly-advanced vision test that objectively measures how well your entire vision system is working. The results of this VEP vision test will help your doctor diagnose various vision disorders, and better understand when changes in your visual function occur.

VEP vision test is a painless, safe, non-invasive way for your eye care provider to objectively measure the function of your entire vision system.

When light from an image enters your eye, it is turned into electrical energy by cells in the retina – the light-sensitive layer at the back of your eye. These cells send the electrical energy back to the visual cortex, the part of your brain where the image is processed.

VEP, or Visual Evoked Potential, uses visual stimuli from a computer screen in different patterns and contrasts to elicit the electrical response from your retina. The electrical energy is then sent to your visual cortex, where the Diopsys® VEP vision test records the electrical signal, and creates a report for your doctor. It is similar to an EKG, but for your entire vision system.
