How We Can Help
Neurodiagnostics Treatment Information
Our neurodiagnostic tests record electrical activity in your brain or muscles. Careful observation and measurement help us diagnose your condition. We provide a complete report to your doctor within 48 hours.
Video Electroencephalography (EEG)
EEG measures your brain activity through electrodes attached to various places on your scalp. These electrodes cause no pain and transmit electrical activity in your brain to our monitoring equipment. Video EEG for diagnosis of seizure disorders typically lasts from 24 to 72 hours. Our goal is to capture observations of behavior and brain activity during seizures. We make you as comfortable as possible for the duration of the test.
Our technologists observe you or your child around the clock. Our neurologists study the record of the video EEG test to determine your diagnosis.
Seizure behavior can be minor, such as unresponsive staring or contortions of the face. Constant observation is important to capture this behavior carefully on video. Often seizure behavior and seizure brain activity coincide. This is common in epilepsy.
Sometimes seizure behavior and seizure brain activity do not overlap. A patient may behave as though a seizure was occurring even though the EEG record does not show seizure brain activity. This may indicate a problem with nerves rather than with the brain. Seizure brain activity with no indication of seizure behavior may represent a more serious condition. This combination may indicate that a more severe seizure will happen in the near future.
EMG helps us determine the reason for weakness in your muscles by measuring electrical impulses inside muscles. A variety of conditions may affect these impulses. Our expert neurologists recognize the signs of these disorders and test your muscles to arrive at an accurate diagnosis.
We perform an EMG test by inserting very thin electrodes through your skin into the muscle. This may cause brief discomfort. With the electrodes in place, a neurologist directs you to move the muscle being tested and records electrical activity in that muscle. Electrical impulses outside the normal range indicate possible causes for the weakness you are experiencing.
