(qEEG, n: quantitative electroencephalography, the computerized analysis of brainwaves )
At Alpine Neurotherapy we provide comprehensive Neurotherapy solutions in-house. We also provide our brain mapping services to other clinics across the U.S.. This process may include EEG acquisition, qEEG brain mapping, and extensive qEEG report generation. Our practice is unique in that our certified qEEG technologist, Joe Castellano, individually inspects every patient's EEG and qEEG for abnormal findings and then provides an in-depth analysis that provides much more insight than a simple qEEG program output alone.
Every patient's journey begins with an EEG acquisition. An electrode cap is put on your head for 10 minutes with their eyes opened and 10 minutes with their eyes closed. Recordings done either here or at other referring clinics all end up with 20 minutes of raw electrical activity recorded at 19 locations on the brain.
EEGs are first processed using a program named WINEEG. The raw EEG recordings are full of artifacts from muscle and eye movements, and these components are removed using ICA (Independent component analysis). Once we have the "clean" file, it is qualitatively looked over for abnormal EEG findings. Certain features, such as spike waveforms, insinuate deeper neurological issues and must be further inspected by alicensed neurologist. Other features are inspected using two key trains of thought:
Vigilance is the inverse of sleepiness.
Signs of a client falling asleep during the eyes-closed recording point towards a sleep disorder.
Signs of hyper-awareness or significant body movement can point towards anxiety disorders.
Phenotypes patterns in the EEG that are genetically linked
There are 11 major Phenotypes that have been studied and each one implies certain behavioral characteristics
"The intermediate step between genetics and behavior" (Gunkelman 2005)
Software packages allow the team to further analyze brains using advanced computational methods.
The findings from these processes is then validated by looking back at the raw EEG.
Fourier transforms allow the frequencies found in the EEG to be quantitatively measured and visualized (A). Coherence measurements provide insight on which parts of your brain are influencing others (B). Adaptive mixture independent component analysis (AMICA) can pinpoint where exactly certain frequency patterns originate and show up in the brain (C). Further frequency analysis can create brain maps that show how brains deviate from a normalized population (D). Low-resolution electromagnetic tomographic analysis (LORETA) gives us a closer look at locations and networks within the brain that deviate from the norm (E).
If need-be, a report can be created on the findings from the EEG and qEEG. At Alpine Neurotherapy we pride ourselve on our in-depth and well-researched reports/maps. All of the analysis from the EEG and qEEG methods outlined above go into creating beautiful and informational maps for our clients. These maps can be provided to therapists, doctors, neurologists, or psychiatrists so that they can better understand your individual brain's inner-workings.
