Before undertaking neurotherapy, a comprehensive assessment of the EEG is necessary to determine which EEG patterns and brain areas would benefit most from training. An EEG assessment is called a Quantitative electroencephalogram, or QEEG. A QEEG involves fitting a cap on the client’s head that has 19 sensors which measure and record the electrical activity of the whole brain. These recordings are analysed mathematically to determine which brain areas have dysregulated patterns of EEG. This process shows which areas of the brain have EEG patterns that could benefit from neurotherapy training.
Scans such as MRI, CT and PET show a visual representation of the brain’s structure, which is a very useful way to determine if there are any abnormalities in the brain such as could occur from a head injury, stroke or tumour. QEEG differs from these brain scans because it shows the function of the brain rather than its structure. It’s important to note that a brain can be structurally normal but have dysregulated function.
