The present study aimed to determine the effectiveness of cognitive rehabilitation on improving reaction time, planning and response inhibition in bipolar patients. This research was a semi-experimental design with pre-test-post-test and control group. The study population consisted of patients with bipolar disorder who referred to psychiatric specialists, clinics and specialized centers of psychiatric services in Tabriz city in 2022 (October to March). Using convenience sampling method, 40 subjects were selected and randomly assigned in experimental and control groups (15 subjects in each group). They were assessed by Mania-Young Scale, Continuous Visual Performance Test (CPT-V), Chronoscope device (reaction time), Tower of London test. The experimental group received cognitive rehabilitation for 6 sessions and no intervention was applied to the control group. Finally, the post-test was implemented. Data were analyzed by Multivariate analysis of Covariance. Results showed that cognitive rehabilitation was effective in improving reaction time, planning and response inhibition in bipolar patients. Consequently, it could be stated that in improving the cognitive abilities of bipolar patients, the application of rehabilitation could provide appropriate setting for other therapeutic interventions.

Aim: The aim of this study was to determine the relationship between executive functions of the brain with attention deficit hyperactivity disorder. Method: For this purpose, in the form of a correlation design, the students of Tabriz University in the academic year of 98-99 were selected by cluster random sampling. Data were collected using Conners Ill Symptom Checklist, Stroop Test, Wisconsin Cards, and Wechsler Working Memory. Results: Data analysis using structural equation modeling showed that the functions of organization, accuracy and concentration, working memory, problem solving and inhibition were able to significantly determine changes in attention deficit and hyperactivity symptoms. Conclusion: The executive functions of the brain have a negative role in attention deficit hyperactivity disorder and deficiency in these functions may predispose to attention deficit hyperactivity disorder. Therefore, in current etiology of attention deficit and hyperactivity, it is necessary to emphasize the evaluation of executive functions and to consider executive dysfunction as the neurological basis of attention deficit and hyperactivity disorder..
