What is video EEG?

The video-electroencephalogram (video-EEG) is a neurophysiological test that allows to record a video to analyze the clinical behavior of the patient and at the same time to perform an encephalogram to study brain activity.

It is used to diagnose paroxysmal episodes.

What does it consist of?

The video-electroencephalogram (video-EEG) consists of video and electroencephalogram recording of epileptic and non-epileptic paroxysmal episodes, in addition to recording the temporal evolution and the number of paroxysmal abnormalities.

Why is it performed?

It is used to diagnose paroxysmal episodes, especially in people with suspected epileptic seizures. The observation of the seizure on Video-EEG allows to determine the region of the brain where the seizures originate so that it can be surgically removed. The results of such an investigation may also lead to the exclusion of the patient from the surgical procedure, because, for example, such a region coincides with an overly extended area that makes surgical intervention impossible.

Preparation for video EEG

For a correct execution of the test, it is necessary that the head is clean and free of products such as gels or lacquers. Cup electrodes are applied to the patient’s head.

How long does the video EEG last?

The EEG video can have a variable duration, from hours (at least 4) to several days, depending on the subject and the patient’s conditions. The subject can be filmed continuously during daily activities. For more information, you can contact a Neurophysiology specialist.
