Why is Prolonged Video/EEG Monitoring Required?

A traditional EEG gives us a "snapshot" of the brain's activity during that recording period. However, this may not give us all the information we need. Our recording has two components:

Video: A camera will record all of the patient's physical activity while he or she is on the EEG. The technologist will monitor the patient at all times. By taping the seizures we can see exactly what happens. All of our technologists and nurses are specially trained to recognize and respond to seizures.

EEG Recording: While in the epilepsy monitoring unit, the patient will also undergo a continuous EEG so we can detect any seizure activity that occurs. It helps us determine where in the brain the seizures begin so we can decide what type the patient is experiencing. It also gives us information about how the patient's brain functions between seizures. This type of recording allows us to make an accurate count of seizures and to see if the patient might have more than one type.

An EEG is a test that detects electrical impulses in the brain. These patterns can be examined to help make a diagnosis in patients with neurological disorders. 

Procedures include:

  • Electroencephalogram - routine, bedside, sleep-deprived, electrocerebral inactivity, video EEG monitoring
  • Long-term video epilepsy monitoring
  • Evoked potentials - visual, brainstem auditory, somatosensory testing
  • Electrodiagnostic testing - electromyography, nerve conduction velocity studies
  • Intra-operative nerve monitoring
