NCS (Nerve Conduction Study)
NCS is a test commonly used to evaluate the function of the motor and sensory nerves of the human body. These studies are used for evaluation of paresthesias (numbness), tingling, burning and/or weakness of the arms and legs. Some common disorders which can be diagnosed by an NCS are peripheral neuropathy, carpal tunnel syndrome, ulnar neuropathy, Guillain-Barre syndrome, myasthenia gravis and spinal nerve compression.
The test involves placing an electrode (sensor) on the surface of the skin in one location, then delivering an electrical stimulus down a nerve several times with another electrode.
The responses of the nerve are recorded on a computer and will tell Dr. Pappas whether the nerve is functioning properly.
This test is commonly used to help diagnose epilepsy (seizure disorders). An EEG involves the recording of electrical activity along the scalp produced by the firing of neurons within the brain. The recording is obtained by placing electrodes (sensors) on the scalp with a conductive gel or paste. Brain wave activity is recorded on a computer for about 20-30 minutes while you lie relaxed on a bed or a recliner. The technologist performing the study may use a flashing strobe light and may ask you to hyperventilate for a short while as a means of seeing if these induce any abnormalities in your brain waves.
The study will tell Dr. Pappas if there seems to be any propensity toward seizures/epilepsy. This can be determined even if you do not have a spell during the recording.
