Video EEG

There are many different types of seizures which often are difficult to diagnose. Continuous video EEG monitoring is the most informative test for establishing the diagnosis of epilepsy and differentiating it from other forms of seizure activity. It is a non-invasive procedure that locates the region of the brain where seizures begin, making medical or surgical treatment more precisely targeted and successful.
The purpose of video EEG monitoring is to record brain wave activity between and during seizures, and to have a video picture of what happens during a typical seizure. The ability to precisely correlate the signs and symptoms on video recordings with the EEG changes provides the most important information for diagnosis and treatment.

    Video EEGs may be performed when:

  • A patient is first being evaluated for epilepsy or other seizure disorder, and the initial EEG testing was not definitive
  • To prepare for epilepsy surgery
  • To determine how well a patient's epilepsy medication regimen is controlling seizure activity

    Video EEGs may be performed when:

  • VEEG 0-2 hrs.
  • VEEG 2-4 hrs.
  • VEEG 6 hrs.
  • VEEG 12 hrs.
  • VEEG 24 hrs.

What to expect during video EEG monitoring

Our epilepsy monitoring unit is fully-equipped with the latest technology, and is staffed 24 hours a day with specialized nurses and technicians. Every effort is made to make the stay as pleasant as possible. Patients can bring books, video games or movies to watch and can have friends and family visit them during their stay.

Similar to a routine EEG, video EEG requires tiny electrodes to be pasted on the scalp. The electrodes are connected to a small box that is worn as a hip pack. This connects by a cable to the wall so that EEG activity can be continuously recorded. This and the need to stay within the video camera's range limit activity during the testing, although patients are able to move about the room.

Patients are recorded for the entire length of their stay, allowing neurologists to compare the patient's physical activity with their brain activity.

Depending on the type of seizures, a patient may be asked to sleep or avoid sleep for parts of the study. Sometimes, flashing lights, hyperventilation (rapid breathing) or use of an exercise bike are helpful to cause a seizure during the study. Patients may need to have a friend or family member with them, especially if a lot of seizures are occurring.
