Diagnostic assessment


Why is it important?


In order to be able to put together a suitable treatment programme for you, an intake interview is not enough. That is why there will always be additional diagnostic tests after the intake. For example, we ask you to fill in questionnaires and to wear a sleep watch for a few days. If there is an intake for an rTMS treatment or neurofeedback treatment, we will perform a neurophysiological examination (QEEG), sometimes supplemented by an extensive (neuro-) psychological examination.


Interpreting the data from a QEEG report requires training and specialist knowledge. To explain it in simple terms, a QEEG records and measures brain activity at 26 different locations in the brain. The information from the QEEG report, together with the results from the intake interview, the questionnaires and the collected information from the sleep watch, are used to draw up a personal treatment plan. In the case of rTMS treatment, a QEEG is also performed to determine whether rTMS can be applied safely. The QEEG is not used to make a diagnosis.


What to expect

You have registered yourself – or your child – with us for an intake interview with additional diagnostic tests. In preparation for rTMS or neurofeedback treatment, a QEEG and/or neuropsychological examination will then be scheduled for you. The QEEG examination usually takes 2 to 3 hours. In consultation with you, the QEEG examination can be scheduled on the same day as the intake interview. Sometimes you will have to go to another location once for the QEEG examination.





Prior to the QEEG assessment

Questionnaire and preparation for the QEEG


1. Complete online questionnaire

Beforeto the QEEG and neuropsychological assessment, it is important that you complete the Brain Resource Company’s online questionnaire (only for clients above the age of 12). Click on the link below to start the questionaire. The instruction is self-explanatory. If necessary, you can view the registration procedure step by step below.


  • What to expect in the online questionnaire
What to expect in the online questionnaire

The following is a manual for using the BRC online questionnaire. Please read this instruction carefully before completing the questionnaire using the button above this section

  1. You have received a confirmation letter from the branch to which you have registered, in which an 8-digit ID code is stated. You will need this code to complete the questionnaire. If you did not receive this code, please contact your branch directly.
  2. Click on the button at the top of this page to go to the registration page to fill in the internet questionnaire.
  3. Register as a new client by clicking on “Register”.
  4. Enter your ID code (the 8-digit ID code as mentioned in point 1).
    You then enter a password (you can invent at least 6 characters and at most 10 characters).
  5. On the screen below, select all ‘Agree’ boxes and then click on ‘Next’ (bottom right).

NOTE: The questionnaire starts immediately after the registration procedure. Here you can fill in all questions and proceed by pressing “next”. Make sure that this questionnaire is fully completed before the survey will take place. NB. If you are unable to complete the questionnaire, please contact us.





2. Preparing for the QEEG assessment

In order to be able to measure your brain activity properly and reliably, it is important that the client complies with the following regulations on the day of the examination:

Wash the hair in the morning with a shampoo without conditioner and let it dry well.


Do not use hair styling products that day (hairspray, gel, wax, etc.). Such products can disrupt the EEG measurements.


Do not apply makeup or oily cream on the face.


Wear comfortable clothing, such as a cardigan, top or T-shirt with a wide neck (no turtlenecks and other clothes with a high neck).


It is important that no alcohol, marijuana or other drugs are used at least 6 hours prior to the study.


Smokers are requested to reduce their smoking on the day of the examination and to stop smoking at least 2 hours before the examination. It is not allowed to smoke during the examination.


Please do not consume caffeine (coffee, tea, cola, chocolate milk, etc.) at least 2 hours before the examination.


Cooperation on these points is very important! Finally, you can bring your own brush after the examination.



3. The assessment


Getting started

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.


Placing the cap

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 40 minutes.
NOTE: the electrodes are perfectly safe, they only pick up activity from your head, they do not discharge any electricity.


Recording the EEG

We can start measuring brain activity once the cap is set. Your brainwaves are measured as you perform a number of basic tasks. Further instructions are given on the computer screen and via a headset. Your therapist or technician will be in a nearby room to check that everything is going well. Parents/carers may sit with their child in the room when QEEG is being performed and may help to answer the questions. The EEG registration takes about 50 minutes. After removing the electrode cap, you will have the opportunity to remove the excess electrode gel from your hair in our laundry room.


Psychometric Testing

If that applies to you or your child, continue with the neuropsychological examination. This test will take about an hour and you will perform neuropsychological tests. During these tests, you will only be sitting in a room behind a touch screen. Children may do this under supervision. Through the headphones and the computer screen is indicated what is expected of you or your child.
