What EEG can video detect?

Epilepsy is a common disease in psychiatry and neurology. EEG examination is an indispensable means to diagnose epilepsy. The commonly used electroencephalograms in clinic include electroencephalogram and ambulatory electroencephalogram. In recent years, video electroencephalogram has been gradually applied in clinic.EEG machine

EEG is the golden standard for diagnosis of epilepsy

Since its appearance in 1924, electroencephalogram has been used in clinic for more than 70 years. As an important basis for the diagnosis of epilepsy, there is no other way to replace it. However, due to the limitations of traditional EEG itself, there are still many shortcomings in the diagnosis of epilepsy. The main disadvantage is the low positive rate.EEG machine

Video EEG makes full use of the advantages of dynamic EEG, combines EEG technology with video technology, and applies computer technology to monitor patients'clinical activities and EEG situation in a long-term synchronous manner. At present, video-EEG is considered to be the most effective method for identifying the nature and type of paroxysmal diseases. It is also a reliable method for identifying epilepsy and non-epileptic seizures. It is one of the important bases for the classification of epilepsy widely used in the world. Five Advantages of Video EEG

Electroencephalograph

1. Video electroencephalogram (VEEEG) can watch synchronous video while playing back EEG. It greatly improves the recognition of epilepsy and some paroxysmal events, and can eliminate artifacts easily. Our hospital has 32-lead dual-camera video electroencephalogram, that is, one camera takes pictures of the whole body of the patient, observes the overall seizure situation, and the other takes pictures of the local area, which can better observe the minor seizures of the face and eyes during epileptic seizures, such as clicking, blinking and so on. Its effect is obviously better than that of a single camera.

    

2. Conventional 24-hour EEG has only 8-16 recording electrodes and limited information. Video-EEG in our hospital is 32 leads, which integrates graphics and text, and greatly improves the diagnosis and identification of epilepsy.

3. Perfect the induction test under the patient's cooperation, that is, eye-opening test, excessive ventilation, intermittent flash stimulation (eyes-opening, eyes-closing and eyes-closing), sleep induction, etc., which greatly improves the positive rate of the examination.

4. The 24-hour EEG sedation measures for young patients were banned when the video-EEG was planned, that is, we do not need to give the children any drug sleep;

5. When conducting scalp lead connection, the ordinary 24-hour EEG requires collodion to fix the electrode position on the scalp surface, which brings pain to the children when the EEG is disassembled. Video-EEG cancels this point
