Long Term Video Monitoring (LTVM)

What is LTVM?

Long Term Video Monitoring (LTVM) is a specialized form of electroencephalogram (EEG) in which a patient is continuously monitored on video while brainwave activity is recorded. This allows doctors to observe brain activity at all times, which allows physicians to observe onset triggers that initiate seizure activity.

What does LTVM diagnose?

LTVM helps identify epileptic paroxysmal electrographic and behavioral abnormalities. This includes epileptic seizures, overt and subclinical and documentation of interictal epileptiform discharges. EEG and behavioral abnormalities can assist in the differential diagnosis between epileptic disorders and conditions associated with intermittent symptoms due to non-epileptic mechanisms.

What are the benefits of LTVM?

LTVM, with video EEG, can be critical for the diagnosis of epilepsy, correlating the time of the physical manifestation of the seizure with abnormal electrical activity in the brain. Video EEG can also be used to detect epileptic activity not detectable in routine EEGs.

Types of behavioral monitoring:

  • Self reporting
  • Observer reporting
  • Video recording
  • Polygraphic and reaction time monitoring
