Having an EEG test



What is an EEG?

An EEG is a recording of the brain's electrical activity, which is made by attaching small discs to the head with a water-soluble paste. It is a safe and painless test and there are no after effects.

Before your appointment

Please make sure that the hair is clean and free of hair oils, hair extensions or other hair products. Prescribed medications should be taken as usual and so should meals. If you have other children with you they should be accompanied by another adult or left at home/school.

For sleep EEG only: to increase the chances of falling asleep while you're here, please go to bed two hours later than normal and get up two hours earlier than normal.

Please contact us on 0207 188 3954 if you have any queries about your appointment.
