Introduction: As depression is a multifactorial disease, it has been treated using medications, psychotherapy, dietary reeducation and various complementary treatments, including neurofeedback. Of the symptoms, impairment in the level of attention has been a concern for several researchers because of the risk of accidents.
Objective: The aim of this study was to evaluate changes in the level of attention of patients with depression treated by QEEG of the neurofeedback TQ-7 system.
Method: Forty-one patients of both genders were evaluated: 13 male and 28 female patients. The evaluation was divided into three steps. In the first, The Learning Curve (TLC) research protocol of the TQ-7 system was used; in the second stage, the level of attention of patients was evaluated before treatment and in the last stage, it was evaluated after treatment. The Digit symbol, d2, Digit Span in correct and inverse order and the Paced Auditory Serial Addition Test (PASAT) were used to assess attention. The results were analyzed using the paired t-test and expressed as means ± standard error of the mean (SEM) with significance set for p-values ≤0.05.
Results: For both women and men, the scores for focus improved with training by 0.429 and 13.461 (p-value <0.001 for both), sustained attention improved by 39.07 (p-value=0.033) and 69.61 (p-value <0.001), and resistance to interference improved by 0.4 and 2.24 (p-value=0.005 for both), respectively. Short-term memory improved significantly just for the women (0.68; p-value <0.001).
Conclusion: The level of attention increases in patients with depression when treated by QEEG using the neurofeedback TQ-7 system.
