It is a painless process.ĭuring the recording itself, it is necessary to sit very still and relax for an accurate recording. Each area will first be cleaned with abrasive gel and an earbud.

20 electrodes will be placed on the scalp with paste as well as one on each ear. The QEEG process should take approximately one hour. What happens during a QEEG? What preparation must be done beforehand?

QEEG has “a level of specificity and sensitivity that is comparable to sonograms, blood tests, MRIs and other diagnostic measures commonly used in clinical practice.” (Thatcher, Moore, John et al, 1999). It is also helpful when tracking changes in brain function as a result of intervention, such as neurofeedback or medication. This tool is not intended to be used in isolation for diagnosis or to replace the medical opinion of a physician, neurologist or other professional, but rather as part of a comprehensive assessment of functioning. This electrical activity is measured while the brain is at rest, and while cognitively involved in various tasks to ensure that the correct parts of the brain are engaged at the correct time. Various factors are investigated in a QEEG that comprehensively contribute to greater understanding of the cause of symptoms and can assist in devising an effective plan for remediation:Ī QEEG measures the electrical functioning of the brain and not the structure.

These maps identify brain regions that are not producing optimal activity. QEEG (Quantitative Electroencephalogram) analyses and processes this digital EEG recording, compares certain factors in the EEG to the norm for the age and gender, and generates topographic maps of brain function. A QEEG is a non-invasive, scientific, evidence-based assessment tool that is used to identify areas of dysregulation in the brain that can cause symptoms such as sleep disturbance, emotional or behavioural difficulties, and learning difficulties.ĮEG (electroencephalogram) measures electrical activity occurring in the brain via electrodes placed on the scalp.
