The Video EEG Monitoring Test is a more specialized form of an EEG test in which the patient is constantly monitored over a period of time. This allows doctors to observe brainwave activity during the time a seizure or spell is occurring.
EEG and video data at the same time permits precise correlation between seizure activity in the brain and the patient’s behaviour during seizures.
Video EEG Monitoring refers to continuous EEG recorded for a more or less prolonged period with simultaneous video recording of the clinical manifestations. Having a correlation of the recorded behaviour (video) and the EEG activity, the diagnosis of seizures or nonepileptic attacks can be made definitely in nearly all cases.
Video EEG Monitoring can be used for the following:
- epileptic seizures
- fainting or black-out spells
- spells of unknown origin
- hallucinations or behavior problems
As a general rule, prolonged EEG-video monitoring should be obtained on any patient who continues to have frequent seizures despite antiepileptic drugs.
A patient who is going to have video-EEG monitoring should bring clothing to the hospital that can be buttoned, as sweaters and shirts to be pulled over the head can interfere with the EEG wires. The patient should also bring reading materials and other things (knitting, sewing, paperwork) to keep busy, as a prolonged hospital stay for monitoring can be boring.
