Neurodiagnostics: “Because Your Brain Matters”

Neurodiagnostics tests are carried out when a patient suffers from the central nervous system (brain and spinal cord) related diseases. The two types of neurodiagnostic testing: imaging tests or scans (x-ray, CT scan, MRI scan, PET scan) and electrical impulse detection (EEG, EMG). Neurodiagnostics helps to record, monitor, and analyze nervous system function in order to promote the effective treatment of pathologic conditions.

Neurodiagnostics is the analysis and monitoring of the nervous system function of patients in order to help physicians decide and perform effective treatment of neurological diseases and conditions, including:

Neurodegenerative Diseases, Epilepsy, Stroke, Headache Disorders, Sleep Disorders , Weakness, Hearing loss, Blurred vision

Neurodiagnostic tests, or, simply, neurodiagnostics, are done when a patients’ illness or condition is thought to be based in the central nervous system, which is comprised of the brain and spinal cord. A neurodiagnostic technologist (NDT) will learn to perform the following diagnostic procedures:


This is probably one of the most recognized tests that an NDT does. Electrodes are attached to the head to track electrical activity in the brain. They can even be used to track sleep patterns. Most often an EEG is the test used to diagnose epilepsy, and is often also used to evaluate the effects of head trauma or infectious disease.

An EEG can help find the cause of headaches, dizziness, seizure or convulsions, and loss of consciousness. Long-term monitoring with an EEG is often combined with video recorded behavior to capture a seizure, which can give doctors much more information about what is happening with patients with infrequent brain disturbances or used to adjust medications.

According to a report by the Alzheimer’s Association approximately 5.1 million people in the United States suffers from Alzheimer’s disease in 2012 and by 2020, the statistical data is likely to touch 16 million bar with one new case appearing in every 33 seconds. Autism and Autism Spectrum Disorders, according to an analysis by the Centers for Disease Control is estimated to affect 1 in every 88 children in the U.S. Similar studies conducted in other countries, for instance the UK National Health Service estimates the prevalence of Autism Spectrum disorders among adults in England is approximately one percent in 2012. The economic cost associated with Autism in the U.S. and U.K. is estimated to be approximately USD 35 billion and USD 45 billion (£27 billion) respectively each year.


This is monitoring performed during surgery, which is used to give surgeons feedback. It monitors neurological structures most at risk during surgical procedures. NDTs report on the functional integrity of the nervous system, including the spinal cord, the brain, and the blood supply to those areas. Surgical procedures that receive intraoperative neuromonitoring include:

  • Spinal surgery for scoliosis
  • Tumors and aneurysms
  • Vascular surgery
  • ENT surgeries

Some of the prominent players in the neurological disorders include Neuro Diagnostic Devices, Inc., Lifelines Neurodiagnostics Systems Inc., Zynex NeuroDiagnostics, Digital NeuroDiagnostics, LLC, Ridge Diagnostics among others.
