Testing

Electroencephalography EEG

Electroencephalography EEG (also known as electroencephalography) is a test used to evaluate the electrical activity of the brain. This involves placing several wires on the head and recording the natural electrical impulses of the brain is producing. By examining these impulses we can determine if someone is prone to seizures. This study is often used to assist in managing someone with epilepsy and in evaluating those with recurrent episodes of passing out. Unlike the other test EEG does require some preparation.

Electromyography EMG

Electromyography or EMG testing is an electrical test of the nerves and muscles. A physician is here to help diagnose certain nerve and muscle disorders, such as “pinched nerves,” radiculopathy, often recommends it scientific, carpal tunnel syndrome or other nerve injuries. It is also use to investigate symptoms such as neck pain, low back pain, numbness, tingling sensations muscle weakness, etc. EMG testing can also be helpful in localizing which nerve or nerves are involved in causing a particular problem. The test can give information about the condition of the nerves and muscles, and whether or not there is damage to them.

Sudoscan

Sudo scan testing evaluates the early stages of distal small fiber neuropathy. This is done by evaluating endocrine glands which are responsible for the sweat response. The sweat glands have a right supply of blood vessels as well as unmyelinated sympathetic C fibers of the autonomic nervous system. In this regard, the test can also evaluate for autonomic dysfunction as well. Autonomic dysfunction can be seen a wide variety of conditions which includes diabetes mellitus, Parkinson’s disease, amyloidosis, and a wide variety of other conditions.

Transcranial Doppler Ultrasound

Transcranial Doppler ultrasound or TCD is a type ultrasound that evaluates the blood circulation within the brain. During the transcranial Doppler ultrasound, sound waves are transmitted through the tissues of the skull. The sound waves allow us to evaluate the speed of the red blood cells moving through the blood vessels within the brain. These are calculated and displayed on a computer screen. This allows us to determine blood flow to various areas of the brain. Transcranial Doppler ultrasound allows us to assess for a wide variety of conditions.

Video Nystamography

Your doctor has requested vestibular testing for dizziness. The test is to differentiate whether the source of dizziness is from the inner ear or brain. It is most useful in leading to recommendations regarding treatment. The test takes about 45 minutes. Goggles are placed over the eyes. In the first round of testing, one eye is uncovered so that you can follow certain targets on a computer screen while an infrared camera inside the goggles records the movements of the covered eye.
