Wash your hair in the morning with a shampoo without conditioner and make sure it is dry.
Please don’t use hair styling products (hairspray, gel, wax, etc.). Such products can interfere with EEG measurement.
Do not apply make-up or greasy cream on your face.
Wear comfortable clothes. There will also be an electrode attached to your collar bone, so it is best not to wear a high collared shirt.
It is important that at least 6 hours before the assessment you do not consume any alcohol or recreational drugs.
Smokers must try to reduce tobacco consumption and must not smoke at least 2 hours before the assessment.
Please do not consume caffeine at least 2 hours before the assessment (i.e. coffee, tea, cola, energy drinks)
You are advised to continue taking any medications as prescribed by your doctor. Do not make any changes on account of doing the QEEG.
First we will need to ask for your written consent to do the QEEG and that you agree to us using the data confidentially for research and training purposes. You will then be taken to the QEEG lab where you will sit and answer some initial questions on a computer about how you are feeling that day, and whether you are prepared to do the QEEG.
A technician (sometimes also your therapist) will measure your head to determine the location of the electrodes. Some areas of the scalp or face may be lightly cleaned with an alcohol wipe so that we can achieve good contact with the skin. A cap of electrodes will then be fitted over the head, it contains 26 electrodes to measure electrical activity, eye movement, muscle tension and heart rate. The setup takes approximately 20 minutes.
NOTE: the electrodes are perfectly safe, they only pick up activity from your head, they do not discharge any electricity.
We can start to measure brain activity once the cap has been set up. Your brain waves will be measured while you complete some basic tasks. Further instructions are given through the computer screen and through a headset. Your therapist or technician will be in a room nearby to monitor. Parents may sit in the room to help if their child is doing the QEEG, it is okay to assist in answering the questions. The EEG recording will last approximately 50 minutes.
After the cap of electrodes have been removed, you will be offered access to a shower or washroom if you wish to remove any excess electrode gel.
After the EEG recording you will then be asked to complete a Psychometric questionnaire on a touchscreen computer. (Children are not required to do this part of the assessment). The Psychometric test lasts approximately 50 minutes.
