Possible deviation of brain activity and degree of this deviation from the norm

 

qEEG screening

Service code s9009

Please note that screening does NOT result in a medical diagnosis; it gives a probabilistic estimate of risk. In other words, the screening gives information on the presence of a pattern in the qEEG that is often – but not always – found in persons with a history of a particular condition.

Short description

This type of screening examines the overall qEEG pattern which reflects general functional state of the brain. The functional state of the brain is the interplay between inhibitory and excitatory processes and (im)balance of regulatory systems of the brain. The inhibitory processes are responsible for suppression of neural electrical activity, whereas the excitatory processes enhance neural electrical activity. Regulation and balance between these two processes determines the main characteristics of human behaviour, adaptation to changing environmental conditions (especially in extreme situations) and is indicative of how well an individual uses his/her resources to carry out different brain functions.

Such psychophysiologically oriented electroencephalography is considered as functional electroencephalography.

Results

By performing this qEEG screening you will get the information on:

  • your unique qEEG type,
  • the presence and extent of any deviation (brain dysfunction),
  • a detailed interpretation of every deviation (the likelihood of neuro-dysfunction or pathology) in qEEG (based on the published scientific studies).

Notes:

  • The results of qEEG analysis are put in context of published scientific studies, the individual’s health history, complaints, symptoms and psychometric and other evaluations (if available).
  • Present psychotropic medication use may affect the results.
