QEEG BRAIN ASSESSMENTS

STEP 1- DATA COLLECTION

During your brain assessment, we record the EEG activity produced by your brain at rest and on task.

To this end, we use standardised 19-sensor-EEG cap placed on your head.

This recording is a safe and non-invasive procedure.


STEP 2- DATA INSPECTION AND ANALYSIS

Once we have collected the EEG data, we carefully inspect it for patterns associated with arousal and vigilance, emotional or cognitive dysregulation, slowing, etc.

We then process and analyse it with the help of cutting-edge, clinically validated, neuro-algorithms to capture neural network connectivity and to determine the most probable source of generation of the EEG rhythms we have detected on the scalp.

Your results are visualised in several different modes – typically, these include raw EEG waveforms, 2-D surface brain maps and 3-D swLORETA deep brain images.  

INDEPENDENT COMPONENT ANALYSIS, EVOKED POTENTIALS AND EVENT-RELATED POTENTIALS

Independent Component Analysis (ICA) is a signal processing method used to separate independent sources linearly mixed in a signal. In the EEG analysis, ICA can help identify the independent cortical and subcortical sources contributing to the raw EEG signal measured on the scalp

In the electroencephalogram (EEG), ICA can be used to separate out artifacts (non-brain activity) embedded in the cortical (brain activity) data.

As a part of our brain assessment, we may investigate the speed and patterns of information processing in your brain, while you perform a computerised speed-accuracy task. One example of such task is the Go-NoGo task. The brain responses to the stimuli, presented in the task, are analysed with the help of Event Related Potentials analysis technique.

Subsequently, we review all results of this in-depth analysis in the context of your history, goals and/or symptoms, and design a personalised neuro-programme, integrating bio-neurofeedback training and selected non-invasive brain stimulation methods.

The qEEG brain assessment also provides an opportunity to meet your neurotherapist in person and to answer any questions you might have regarding the process.
