Long-term continuous video electroencephalogram (EEG) monitoring is done during an inpatient hospital stay that can last from five to seven days. The goal of this evaluation is to record your typical seizures using a video camera and continuous EEG monitoring so that your doctor can better diagnose and treat you. This test helps doctors better understand and localize where in the brain your seizures come from and provides much more information than a traditional EEG, which lasts about a half hour and gives merely a snapshot of the brain's activity during the particular time of the recording period.

A long-term video electroencephalogram (EEG) monitoring test for epilepsy has two components:
  • Audio/video: A microphone and camera will record all your physical activity while you are on the EEG for review. Monitors are placed at the nursing station facing away from traffic areas to protect your privacy. By videotaping your seizures we can see exactly what happens during one of your seizures. This is usually more accurate than reports you or a family member can give us about your seizures.
  • EEG recording: This part of the test allows us to detect seizure activity that may occur, even if you are not aware it is happening. It helps us determine the type of seizure you are experiencing and may provide helpful information to improve your treatment. It also gives us information about how your brain functions between seizures. This type of recording allows us to make an accurate count of your seizures and to see if you might have more than one type of seizure.
