Neurodiagnostic Services

Neurodiagnostic services at the St.Vincent Neuroscience Institute are provided by nationally credentialed technologists who conduct a battery of neurological testing procedures to evaluate neurological, visual, auditory and peripheral nerve conditions. These tests can provide valuable information not available with any other form of testing.

St.Vincent is the first hospital in Indiana to receive accreditation from the American Board of Registered Electroneurodiagnostic Technologists.

Electroencephalogram (EEG)

An EEG is the only diagnostic test that records comprehensive brain activity. It is useful for evaluating issues such as:

  • Numbness
  • Dizziness
  • Convulsions
  • Staring spells
  • Mental status changes
  • Behavioral problems

Video EEG

Video EEGs are especially useful for infrequent episodes, atypical clinical behavior or chronic seizure disorders. EEG and video can be recorded simultaneously during in-patient hospitalization. Test duration can range from 23-hour observation to several days.

Evoked Responses

Evoked response evaluates the nervous system pathways:

  • For the auditory nerve (BAER)
  • For the optic nerve (VER)
  • From limbs through the spinal cord to the brain (SSER)

Evoked response testing is valuable in evaluating issues including:

  • Visual/auditory problems
  • Paresthesias
  • Multiple Sclerosis
  • Demyelinating disorders
  • Spinal cord injury

Intraoperative Monitoring

Intraoperative monitoring monitors brain activity, the spinal cord, nerves and/or nerve roots during a variety of surgical procedures. A technologist is present during the surgery. A neurologist is available to monitor the case remotely with our advanced network capabilities.

Intraoperative monitoring provides instant feedback to the surgeon regarding observable changes, irritability and hardware placement.
