Neurodiagnostic



EMG and Nerve Conduction Studies


EMG is a test of muscle function. Nerve conduction studies is a test of nerve function. Together, both studies help in the diagnosis of people with problems such as
  • tingling
  • numbness
  • weakness
  • pain
Both tests are performed in a comfortable environment at our Greenwich Office, and can be arranged by calling our office. All of our physicians are board certified and fellowship trained to perform these studies.


Autonomic Nervous System Function Studies


Autonomic Nervous System function tests evalute the neurological control of heart rate, blood pressure and sweating. Our laboratory is only one of a few such centers in the northeastern United States. These studies are noninvasive, and are performed with the most advanced tools for heart rate and blood pressure measurements. The battery of tests used to evaluate disorders of the nervous system such as:
  • low blood pressure
  • fainting
  • disorders of sweating (too much or too little)
  • exercise intolerance
  • dizziness and lightheadedness
Tests are performed in the Autonomic Function Laboratory at Greenwich Hospital


Electroencephalography (EEG)


EG is the electrical study of brain waves. It is performed by placing adhesive electrodes on the scalp, and measuring the electrical activity of the brain. EEG can help to diagnose problems such as:
  • seizures
  • epilepsy
  • unexplained alterations in consciousness
  • abnormal movements
  • dementia
The EEG is a non-invasive study that generally takes 30-40 minutes to perform, and is done in the EEG Laboratory at at our office at 49 Lake Avenue and Greenwich Hospital.


Transcranial Doppler Ultrasound (TCD)


Transcranial doppler ultrasound, also known as TCD, is an exciting new technology used to evalute the integrity of arteries in the brain. We use Power M-Mode technology that helps to secure stable and reliable intracranial signals, which can be used to evaluate for stroke, and stroke risk. Some of the conditions where this is useful include
  • post carotid endarterctomy evaluation
  • dizziness
  • visual changes
  • weakness, problems with language, and traumatic brain injury
