What is a QEEG Brain Scan?

The Perth Brain Centre uses the latest functional brain imaging technology known as Quantitative Electroencephalogram (QEEG) Brain Scans and 3-Dimensional Brain Mapping, using Low-resolution Electromagnetic Tomography (LORETA).

Everything we think and feel and do is the result of brain activity. QEEG measures this electrical activity of the brain, known as “brain waves” and then, using specialised software, compares that unique pattern to known databases of “normal” and “abnormal” patterns.

The results of this complex analysis are used to generate detailed images, known as “brain maps” which can help to pin-point the areas of the brain that are not working normally. This important information is used to help develop treatment programmes and to monitor progress.

Who can benefit from a QEEG Brain Scan?

More than 90% of people are interested in looking after their brain health, and if you are interested in knowing more about your brain then you may benefit from a QEEG Brain Scan. QEEG Brain Scans are unique within the field of neuroscience and brain-imaging - Unlike standard CT and MRI scans which provide information about brain structure, QEEG Brain Scans provides unique information about how the brain is working. At The Perth Brain Centre we also recommend QEEG Brain Scans to help guide effective treatment for people looking for help with:

 

QEEG measures brainwaves

All of our thoughts and actions are the result of the activity of the 100 billion neurones in our brain.  Brainwaves are produced by the synchronised electrical activity from all these neurones.

Brainwaves are normally measured in Hertz (cycles per second) and they are often divided into Delta, Theta, Alpha, Beta and Hi-Beta bands (ranging from very slow to very fast frequencies).

 
 

QEEG and EEG, CT, fMRI, MRI, SPECT & PET

QEEG is unique within the field of neuroscience and brain-imaging. Unlike standard CT and MRI scans which provide information about brain structure, QEEG provides unique information about how the brain is working. QEEG is the only examination that directly and objectively measures brain function, precisely mapping brain activity and permitting accurate “pattern recognition”, impossible with the routine visual analysis of ordinary EEG. QEEG also differs significantly from Functional MRI (fMRI), PET and SPECT scans all of which assess brain activity indirectly by measuring blood flow, the latter two examinations also requiring the use of radioactive tracers.

Research

QEEG is a primary tool in neuroscience and is used in research centres all over the world. It is used to study conditions including: ADHD and Learning Disorders, Alzheimer’s Disease, Anxiety and Panic Disorders, Autism (ASD), Developmental Disorders, Chronic Pain, Depression, Dizziness and Vertigo, Epilepsy, Fibromyalgia and Chronic Fatigue Syndrome, Insomnia and Sleep Disorders, Migraine and Chronic Headaches, Post-Concussion Syndrome, Traumatic Brain Injury and Stroke.
