DIAGNOSTIC TESTING
The Center for Complex Neurology, EDS & POTS provides on-site testing to assist in your diagnosis.
Nerve Conduction Studies/Electromyography (EMG)
This important test of nerve and muscle function involves using electricity to test nerves and needles to record muscle signals. Although uncomfortable this test can very valuable to help diagnose your condition. Dr. Saperstein has completed advanced training and is board certified in Electrodiagnostic Medicine and Clinical Neurophysiology.
Single Fiber EMG
This is a complex test that can be pivotal in the diagnosis of myasthenia gravis and related conditions. Dr. Saperstein is one of only a few neurologists in the Valley who performs this testing.
Skin Biopsy
Skin punch biopsy can be used to diagnose a condition called small fiber neuropathy. This in-office procedure takes only a few minutes to perform and requires only a couple of small pokes of local anesthetic. Dr. Saperstein is a recognized expert in the interpretation of this test.
Autonomic Testing
Autonomic testing is a complex group of procedures used to diagnose POTS and other autonomic disorders. It entails measurements of multiple parameters, to include blood pressure, heart rate, EKG, breathing and sweat function. Patients are also placed on a “tilt table.” This involves being tilted upright for 10 minutes to see how gravity affects cardiovascular and brain function. To improve the diagnostic yield of testing, the Center also employs measures of blood and flow and electrical activity of the brain. We are the only facility in Arizona which includes this testing with the tilt table.
Electroencephalography (EEG)
An EEG measures brain waves. This test can be used to determine the cause of an alteration or loss of consciousness, such as fainting or seizure.
Evoked Potentials
Evoked potentials measure how electrical signals travel through our nerves, spinal cord, and brain. These tests can sometimes provide diagnostic information that cannot be obtained from an MRI scan. Evoked potentials can be useful in identifying neurological complications that can occur from EDS and other hypermobility disorders.
Transcranial Doppler (TCD)
TCD testing uses ultrasound to measure blood flow within the skull. At the Center we combine TCD with tilt table testing or changes in head position to identify abnormal changes in blood flow that could be causing your neurological symptoms.
