“…However, we observed this correlation only in the control group at baseline, whereas greater posterior asymmetry was related to more severe symptoms. In a previous study from our laboratory, we also did not find any correlation in depressed elderly subjects (18). In one of the few studies on elderly women, Kline et al (25) found that right frontal asymmetry did not vary significantly when valerian odor (an unpleasant stimulus) was used.…”

“…Electroencephalography (EEG) is a valuable tool used to assess electrophysiological changes associated with mental illness, and has shown increasing utility in assessing brain function in clinical studies of depression (17,18). The effects of exercise on the reduction of mood symptoms are observed by analyzing cortical hemispherical activity (19)(20)(21)(22)(23), especially in the alpha band (8)(9)(10)(11)(12)(13).…”

Background: Quantitative electroencephalogram (qEEG) changes in chronic hepatitis C patients treated with interferon-α (IFN-α) have previously been reported. However, whether IFN-α-induced depression is related to changes in qEEG during IFN-α treatment remains unclear. Method: Fifty chronic hepatitis C patients were enrolled and IFN-α was administered intramuscularly at 9 × 10⁶ IU daily for the first 4 weeks and then 3 times a week for the next 20 weeks. Serial EEGs obtained before and at 4 weeks after treatment were assessed. The absolute power for each frequency band was determined using qEEG techniques. Differences in the rate of change in absolute power for each of 6 frequency bands (δ, θ₁, θ₂, α₁, α₂ and β) were assessed between patients with and without major depression using the Mann-Whitney U test. When significant differences in the rate of change in absolute power for each frequency band were observed, differences in the rate of change were also assessed between patients with and without psychological complications using the Mann-Whitney U test. Results: Major depression due to psychological complications during IFN-α treatment was reported in 10 out of 50 patients. In the θ₁ band, the difference in the rate of change was demonstrated to be significant (p = 0.0036). Moreover, at the central, frontal, parietal, and temporal locations, the rates of change were also significantly different. Conclusion: In IFN-α-treated chronic hepatitis C patients who were diagnosed with major depression, qEEG changes were more obvious and widely distributed.

“…Although depressed participants had greater right frontal and left parietal activity than non-depressed participants this finding was not significant (Deslandes et al, 2008). Decreased alpha activity in the right hemisphere may be associated with depression, however, findings have been inconsistent possibly due to the fact that gender, other mood disorders such as anxiety and age and handedness may impact alpha activity in these regions also (Morgan et al, 2005, Stewart et al, 2011.…”
