Clinical QEEG Assessment

What is qEEG?

The Quantitative EEG assessment allows your practitioner to assess your brain functions more accurately. An EEG (electroencephalograph) is a non-painful, relatively brief (90 min) procedure. It measures your brain’s activity (brainwaves) via conducting electrodes that are placed at the surface of your scalp. qEEG is the analysis of the digitised EEG and a form of “brain mapping”. Your results (brain waves and patterns) are compared to normative databases. This information can be used as an adjunctive diagnostic tool alongside the clinical assessment. It helps guide and monitor specific and effective treatments.

Types of brainwaves measured (from slowest to fastest):

  • Delta waves
  • Theta waves
  • Alpha waves
  • Beta waves

Clinical examples include:

In ADHD, there might be excess theta and alpha waves, and low levels of Beta waves. In anxiety, too much alpha wave activity might be present, making it difficult to relax. The qEEG could help determine whether your child’s behaviour is due to ADHD, processing difficulties, depression or anxiety.

Procedures explained

Complete the questionnaire

In order to measure brain activity reliability, please follow these steps:

  • Wash your hair in the morning with shampoo, but no conditioner. Dry your hair well. 
  • Do not use any products on your hair before or after drying. 
  • Do not apply make-up or creams to your face. 
  • Wear comfortable clothes. Do not wear a high collared shirt/jumper
  • Do not use alcohol or drugs for at least 8 hours prior to the assessment.
  • Try not smoke for at least 3 hours prior to the procedure.
  • Do not have any caffeine for at least 3 hours prior to the procedure.  
  • Discuss your medication with your doctor. If not given any alternate instructions, continue all regular medication.

On the day

You will be asked for written consent to perform the qEEG and, if willing, share your information confidentially for the purpose of research and training.

The technician will then guide you through the qEEG process and attach the scalp cap and electrodes for monitoring.

The set-up takes approximately 40 minutes and the EEG recording process, another approximately 50 min. It is a non-invasive and painless process. Conduction gels and alcohol wipes are used. Please report any product allergies or sensitivities to your clinician.

You will be given a follow-up date, at which time the report and feedback of the findings will be provided.
