“…Elevated power in alpha, theta, and beta bands in posterior cortical areas was observed in our studies (Grin-Yatsenko, Baas, Ponomarev, & Kropotov, 2009, 2010. Increased theta power has been found in depressed patients in several studies (for review see Olbrich & Arns, 2013).…”

Electroencephalographic (EEG) findings on depressive patients indicate theta and alpha activity higher than in normal controls. Extensive literature reports on the effectiveness of neurofeedback techniques in the treatment of cognitive and behavioral disorders by training the patients to modulate their brain activities, as reflected in their electroencephalogram. Three unmedicated, depressed individuals participated in this study of infra-low frequency neurofeedback (ILF NF) training. Along with the pre-and posttreatment Depression Rating Scales assessment, quantitative EEGs (qEEG) were recorded in eyes-open and eyes-closed resting states and during the visual cued Go/NoGo task before and after 20 sessions of training. Along with remission of the clinical symptoms of depression, significant decrease of theta power over frontal and central areas was observed in all three patients under all test conditions. These qEEG dynamics might be a correlate of ILF NF-related recovery of the appropriate level of frontal cortical activation.Keywords: neurophysiology; neurofeedback; depression; qEEG; infra-low frequency

“…A qEEG may soon be considered essential to confirmation of diagnosis and treatment choice. Similar arguments apply to other psychiatric conditions, especially depression, where promising qEEG results have also been obtained (Grin-Yatsenko et al 2010). …”

Psychiatry differs from other clinical specialties in several important respects. At a basic level, physical examination of the body is conspicuously absent in psychiatry. The diagnostic process employs almost no physical laboratory-based tests such as blood, urine, or CSF (cerebrospinal fluid)
analysis. Nor are the various imaging modalities instrumental in diagnosing a psychiatric condition. Such investigations are almost ubiquitous elsewhere in medicine, yet insofar as they are utilized in psychiatry they are overwhelmingly aimed at excluding non-psychiatric conditions. Moreover,
modern-day psychiatry is, more than any medical specialty, a minefield of controversy. Psychoanalysis, for example, still widely practised, is viewed by many psychiatrists in the field as little more than quackery (Webster 1996), and even within the disciplined ranks of those committed to
neurobiological models of disease disagreement exists as to whether schizophrenia and bipolar disorder represent distinct pathologies (Maier, Zobel and Wagner 2006). As if the unusual nature and degree of internal debate regarding psychiatric theories and therapies were not enough, controversy
extends so far as to question the very existence of psychiatric conditions. As Thomas Szasz, Professor of Psychiatry at Syracuse University, famously opined, '“mental illness” is not the name of a biological condition' (Szasz 1973)

“…Functional brain changes in early stages of depressive disorder in adults were displayed in three frequency bands of electroencephalography (theta 4-7.5Hz, alpha 7.5-14Hz, beta 14-20Hz, both in Eyes closed and Eyes open conditions). A diffuse enhancement of beta power (correlating with anxiety symptoms) and an increase in theta and alpha activity at parietal occipital sites were revealed (Grin-Yatsenko et al, 2010). The presence of structural and functional abnormalities in the superior temporal gyrus and in the amygdala in children and adults with generalized anxiety disorder was found (De Bellis et al, 2000, 2002Quirk et al, 1997).…”
