Various studies have shown some relationship between brain wave abnormalies and depression. The current study aimed to examine the effectiveness of the real neurofeedback treatment compared with mock neurofeedback in decreasing major depression severity of symptoms and change on ? waves into a desirable pattern among some patients who suffer from major depression disorder. The study chooses six patients who were suffering from major depression sufferers and they were randomly placed in two groups called real neurofeedback and mock neurofeedback group (placebo). The two groups were treated for a twenty sessions twice a week. The two groups were examined before, during and after the treatment by Beck Depression Inventory II, Hamilton Depression Scale. The research data were examined through the analysis of the size effect, improvement percentage and charts. The data resulting from the size effect and the improvement percentage suggested that the real neurofeedback was more effective in regulating brain waves and in decreasing major depression disorder symptoms in comparison with the mock neuro-feedback and the groups were significantly different from the clinical point of view. The effectiveness of the real neurofeedback was not from the changes in placebo and it can be used as a complementary treatment in treating major depression disorder. The findings of the current research were congruent with those of the related studies.
