The effectiveness of neurofeedback with computrized training in improving working memory in adults with attention deficit disorder/ hyperactivity

Attention deficit / hyperactivity disorder, is a common psychological disorder in persons, that continues from childhood into adulthood and leads to problem in various aspects of their life, such as personal, social, professional, and executive function such as working memory. Several studies indicate a close relationship between working memory deficits and attention deficit / hyperactivity disorder. Given the lack of studies on the effectiveness of neurofeedback in improving working memory in adults with ADHD, this study was designed to evaluate the effectiveness of neurofeedback in working memory.
Research design was experimental with pre-test and post-test and control group and carried out on adults with attention deficit / hyperactivity disorder referred to the Atieh clinic in Tehran .After reviewing inclusion and exclusion criteria,16 persons based on purposive sampling were selected in 2 groups of 8 cases as experimental and control groups. The research instruments were the Beck Anxiety Inventory, Beck Depression Inventory, Inventory adult attention deficit/ hyperactivity disorder of Barkley, vital cns test, auditory and visual integrated test signs. Data analysis, through SPSS software using U Mann-Whitney, was performed. The independent t-test, Wilcoxon and Kruskal-Wallis tests were used also for complementary results. The protocol used in this study, was increasing of beta waves on FZ.
The results showed that neurofeedback was led to a significant increase in working memory in experimental group.
According to the results of this study, which is consistent with results of the researches done in this field, neurofeedback increases frontal lobe activity and activation of neural circuits involved in executive function and working memory, and improve executive function and working memory deficits in patients with attention deficit / hyperactivity disorder. As a result, given the efficacy of neurofeedback in improving working memory, using this method, is suggested for the same treatment.
