How is the Fullcap EEG/QEEG performed?
The EEG/QEEG procedure is derived by measuring the electrical activity (EEG) of the brain by a non-invasive (nothing is put inside the brain) procedure of placing a cap with multiple electrodes over the scalp.
EEG recordings are taken across a number of conditions or tasks, including a) eyes closed, b) eyes open, c) cognitive test of graded difficulty. The EEG data is then processed using mathematical algorithms and statistical analysis. Data is then evaluated for percentage change across states and compared with a normative database for state variance.
How reliable is the QEEG for diagnostic purposes?
The diagnostic use of the Quantitative EEG (QEEG) has a strong research base that spans over ten years.
Experts in neuroscience regard EEG/QEEG as the definitive diagnostic assessment for neurological & neuro-developmental disorders including epilepsy, ADD/ADHD and other neuro-psychological conditions such as anxiety, depression, obsessive compulsive disorder, etc.
How is the QEEG relevant in the context of medical conditions?
QEEGs have been evidenced to be efficacious in predicting differential response rates to conventional medications. In one study, approximately 80% of obsessive compulsive (OCD) patients who exhibited increased alpha (brainwave bandwidth) power responded well to a class of medication called Selective Serotonin Reuptake Inhibitors (SSRIs), compared to 80% of OCD patients with increased theta activity who did not respond to SSRIs (Princhep 1993).
How does the QEEG help in the treatment of special needs children?
In addition, using QEEG to guide treatment markedly increases the efficacy of treatment in contrast to simply relying on behavioral diagnosis (Gunkelman, J. 2006). Within the autistic population for instance, QEEG has been successfully used to guide neurofeedback (EEG Biofeedback) training leading to significant improvements in speech, communication and reduced aggressiveness (Neubrander, J., Linden, M., Kerson, C., Gunkelman, J. 2011).
