What is EEG/electroencephalography?

EEG ist a method of neurophysiological examination. It provides information about the function and maturation of the brain’s nerve cells.

The techniques vary depending on age and state of health of the child or adolescent. There is no pain involved. After application of a contact cream to the skin, electrodes are attached with a special cap that is fitted to the head. At the same time, the heart activity is monitored with an ECG.

The brainwaves are then recorded on the computer and, to enabale correlation of brain activity to reactions, your child will be filmed during this recording. The video will be deleted after the recording has been evaluated.

Length of investigation: 1-1 ½ hours

Methods of investigation


Recording of EEG in an awake child. Depending on age and cooperation, the children are prompted to close their eyes.


In special cases we conduct EEGs while your child sleeps. This can provide information about sleep phases. These EEG investigations take place in the early afternoon aiming for a short afternoon sleep. In preparation, have your child go to bed later than usual the night before and get up earlier in the morning of the EEG.

Methods of provocation

Hyperventilation (deep breathing during approx. three minutes) as well as photostimulation (stimulation with light with a stroboscope) can provide added information or signs of specific types of epilepsy.


Please also observe the written information you receive and don’t hesitate to contact us if you have questions.

The EEG will succeed best with a quiet and relaxed child and good preparation is key. Your child should not be hungry. In small children, a pacifier, bottle or favorite toy may be helpful.

The EEGs are done by specially qualified staff in a quiet atmosphere. Mobile phones must be turned off or be in flight mode.

On the day of investigation please ensure your child’s hair is free from any hairproducts like gel, spray or oil.
