What is a Quantitative Electroencephologram (QEEG)?
QEEG brain maps with comprehensive images and reports are available. The QEEG is a powerful evaluative procedure researched and validated since the 1970’s to identify maladaptive brainwave patterns associated with different physiological conditions and a measure of overall brain functioning. It can identify strengths and weaknesses in the organization of the electrophysiological status of one’s brain so as to aide in the efficient and optimal design of a neurofeedback treatment protocol. The brain map generates a proactive treatment plan to work from and to retrain, rewire, and reprogram the brain to address physiological, cognitive and emotional problems through neurofeedback.
There are at least three reasons for the Quantitative Electroencephologram (QEEG) Evaluation-sometimes referred to as a “Brian map”: (1) To assess the neurological status to determine to what extent there is a neurological basis to a patient’s ongoing physiological complaints (i.e.; attention problems, pain, headaches, symptoms subsequent to head injury, etc.); (2) To identify strengths and weaknesses in the organization of electrophysiological status of one’s brain so as to aid in the efficient and optimal design of a neurofeedback treatment protocol; and, (3) As an evaluation of treatment to evaluate objectively the efficacy of neurofeedback treatment by comparing a patient’s QEEG before and after treatment.
The Quantitative EEG is a powerful assessment procedure to identify maladaptive brainwave patterns as well as overall brain functioning. The QEEG evaluation measures “real time” brain physiology. Abnormal activation (power) found on a QEEG evaluation may indicate dysfunction within a location of the brain or within a network of neurons responsible for certain functions. The QEEG is also a good measure of different brain network dynamics including how specific brain networks connect, share information; and/or have difficulties connecting with other brain networks. The QEEG also provides data on the speed of information sharing between brain networks.
A QEEG evaluation includes a statistically reliable database comparison of the individual’s brainwave patterns to sample populations of those of “normal individuals” of the same age and gender as well as from sample populations of persons with psychoneurological problems such as Attention Disorders, learning disabilities, traumatic brain injury, dementia, anxiety, depression, bipolar disorder, obsessive-compulsive disorder, and disorders in the autism spectrum. The brain map generates a proactive treatment plan to work from and to retrain, rewire, and reprogram the brain to address physiological, cognitive and emotional problems through neurofeedback.
Research on the QEEG has demonstrated a strong correlation between EEG brain wave abnormalities and a variety of cognitive, behavioral, emotional, and learning disorders. Research indicates that the brainwave EEG patterns demonstrate cortical activity found in attention, learning, and emotional conditions. This research has been cross-validated with other neuroimaging techniques. By comparing the brain wave patterns found in a QEEG evaluation with others in a normative group of the same age, we can discover how a given person’s brain waves differ from the normal population. For references on studies validating the efficacy of the QEEG go to PubMed (the National Library of Medicine portal) and search “QEEG” where hundreds of articles since 1970 can be found. For more specific articles on the QEEG’s sensitivity towards certain conditions enter the condition (i.e. “QEEG and ADHD”).
After a Quantitative EEG is completed, patients will receive a QEEG report that will summarize statistical data base comparisons, brain maps, as well as samples of typical and atypical EEG data. Patients will receive a comprehensive and clear explanation of the QEEG findings by Dr. Leiderman and neurofeedback treatment recommendations if indicated. The information obtained by the QEEG brain maps can be used to train brain activity towards a population norm. As part of the QEEG report, patients may also receive 3 dimensional Loretta images. The Loretta provides not only validation to QEEG findings, but includes 3-D images of other interior brain structures besides the cerebral cortex that contribute to one’s psychoneurological problems and that will be targeted in neurofeedback treatments.
