Advanced qEEG Screenings
EEG is the result of dendritic and postsynaptic currents of many cortical neurons firing in nonrandom partial synchrony. The oscillatory activity of neuronal pools reflected in characteristic EEG rhythms constitutes a mechanism by which the brain can regulate changes of a state in selected neuronal networks to cause qualitative transitions between modes of information processing and as consequence – changes in the general brain arousal, global attentional readiness and cognition status, sensorimotor and semantic activity, and behavior. Since various EEG characteristics are closely related to different aspects of functional state of the brain as well as to cerebrovascular function, metabolism levels and brain integrity it is possible to use qEEG as a screening tool for various conditions and risks.
qEEG screening is not a diagnosis. We tell what neuro-science knows about qEEG in relation to different psycho-physiological conditions including cognitive functions and risks of brain and mind dysfunction. qEEG screening gives the probabilistic estimates of the risk. In other words, such screening provides information on the presence of a pattern in the qEEG that is often found in persons with a history of a particular condition.
Important note: qEEG screenings are ancillary tests that are not intended to provide a diagnosis by themselves, but are used to evaluate the risk, nature and severity of dysregulation in the brain. Diagnosis is performed ONLY by the clinician, who integrates the subject's medical history, clinical symptoms, neurocognitive tests and the qEEG screening,s as well as other information to render a diagnosis.
qEEG screening is intended to draw the physician’s attention to features that may have been otherwise overlooked.
Accumulated scientific studies and converging evidence make possible to perform the following qEEG screenings:
