Neurology is the scientific study of the nervous system. Ascension Crittenton Hospital Medical Center uses a variety of procedures to diagnose neurological disorders or diseases. These include:
Electroencephalography (EEG) – An EEG records ongoing electrical activity in the brain by means of electrodes attached to the scalp with paste. This painless procedure will normally last about one hour while the patient rests in an easy chair. The study will help diagnose structural diseases of the brain, such as strokes, tumors, seizures, faints or blackouts as well as conditions like memory loss, mental decline and confusion.
Evoked Potentials (EP testing) – This procedure records the brain’s electrical response to visual, auditory or sensory stimulation. Each test lasts from about 30 minutes to one hour. The patient will sit in an easy chair during the tests with electrodes pasted to your scalp as in an EEG.
Electromyogram (EMG) and the Nerve Conduction Test (NCT) – These procedures measure and record the electrical activity of muscles and nerves. These are helpful tests for patients with numbness, tingling, weakness, fatigue or pain in the back, neck, limbs or other parts of the body. Small needles are inserted into the muscles and mild electrical impulses are given to stimulate the nerves. The patient lies on an examination table during the test, which lasts about 45 minutes.
Electronystagmography (ENG) – Is a battery of tests that record a patient’s eye movements. This test is generally performed when a physician needs more information to diagnose a patient’s dizziness or unsteadiness. The physician uses this information, along with information from other clinical tests, to make the diagnosis.
