QEEG Testing is the "GPS" Map of the Brain

MRI and CT scans tell us what the brain looks like. Functional neurologists use tools that tell us how the brain is working. Examples of this are evoked potentials, VNG and balance testing. We are also able to do a test called a QEEG which measures electrical activity and 'maps' out areas of strength and weakness. It is sometimes called a Brainmap.

We offer this testing at the CIIT Center and I will post cases to show how this amazing technology can guide treatment.

The attached map is of a young boy diagnosed with a speech delay and ASD. The map shows 5 different 'speeds' of brain wave processing from slow to very fast - left to right. Delta on the left is the slowest and is usually associated with sleep. The beta and high beta on the right is most active during active thought and wakefulness. The top should be all green and yellows and reds show increased activity of those waves and blue shows a slowing of the waves.

In the lower regions, the lines also represent abnormality, red being hyper active and blue being hypoactivity.
This patient shows red or hyperactivity of delta (slow) waves in the language regions of the brain and characteristic hyper coherence meaning his brain is over connected and individual regions can't work as independently as they should. It also shows blue lines at the bottom meaning processing speed is slow.
The great thing about this map is it gives us treatment targets for neuromodulation treatments like TMS, neurofeedback, tDCS and TCES - all non-invasive ways to enhance brain function.
I will post more cases like migraine, dementia, depression and anxiety soon. There is so much that can be done for people with chronic neurological conditions! - Dr. Micahel Gruttadauria
