A Video EEG (VEEG) is a painless, non-invasive technique primarily used in the diagnosis or evaluation of seizures. It may be recommended for attention disorders, fainting spells, developmental delay, headaches, or learning problems.
The VEEG records ongoing electrical activity generated by the neurons in the brain by means of electrodes attached to the scalp. Abnormal EEG signals have electrical spikes and waves in the brain that are common in epilepsy even if the child does not show physical signs of having a seizure. During the VEEG, your child will have video recording that is time-locked to the EEG recordings. The video/EEG recordings aid the epileptologist in the interpretation of your child’s EEG.
During VEEG testing, a process called Evoked Potentials (EPs) may be done. This measures the electrical activity produced by external stimulation such as flashing lights, sound clicks, or the stimulation of peripheral nerves.
What to Expect
Prior to being admitted to the EMU for VEEG testing, we ask the parents to wash your child’s hair. Please do not use any other hair products including: conditioner, gel, mousse, or oils. The EEG technologist will use glue, called collodion, to apply the electrodes to your child’s scalp. A special cap will be placed over the electrodes then the head will be wrapped. The electrodes will be checked regularly to ensure that EEG activity is recording.
Benadryl may be given if your child experiences itching with the cap and glue. It is important to keep your child from scratching the electrodes. The technologist will remove the electrodes on the day your child is to go home. Do not remove the electrodes yourself or allow your child to remove them.
