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 conversion evidences make possible to perform the following qEEG screenings:

Brain maturation process (for ages bellow 19 years old)
Brain aging (for ages above 50 years old)
Possible deviation of brain activity and degree of this deviation from the norm (for ages above 19 years old; mature brain)
Potential risks of Mild Cognitive Impairment (MCI) / Vascular Dementia (VD) / Alzheimer Disease (AD)
Potential risks of Attention Deficit/Hyperactivity Disorder (AD/HD) and related diseases
Potential risks of Depression and determination of affective style
Potential risks of Anxiety and/or anxious individuality
Potential risks of Schizophrenia and/or schizotypical individuality
Potential risks of Alcoholism
Potential risks of Brain Ischemia (blood insufficiency)
Potential risks of Traumatic Brain Injury (TBI)
Potential risks of Post-Concussion Syndrome (PCS)
Potential risks of long-term consequences of childhood emotional/psychological trauma / risk of Post-Traumatic Stress Disorder (PTSD)
Potential risks of Psychopathy
Potential risks of Migraine
Potential risks of Bipolar Disorder and related diseases
Potential risks of Tinnitus
Potential risks of Neurosis and determination of neurosis type
Potential risks of Epilepsy
Degree of recovery from substance abuse / addiction
