This research was designed and conducted to compare the cognitive condition of two groups of healthy people and MTBI patients one year after their injury in terms of both executive functions and working memory.In this causal-comparative study, which was conducted from February 2017 to October 2018, two groups of individuals, 48(MTBI), male Patients from 30 to 55 years old who were admitted to the ICU in Shohadaye Haftome Tir and Baqiyatallah Hospitals and 64 healthy men from personnel and Patients' Visitors that had all the criteria for entering the research were chosen. Both groups were tested with two scales Wisconsin and Wechsler Number Memory. The two groups had significantly difference (p<0/01), in the executive functions at the levels of Categories, Perseverative, correct and error responses, number of trials to complete first category and conceptual level responses.Also, the results show that the two groups had significantly difference(p<0/01), in the forward and reverse auditory memory, forward and reverse visual memory, total score of auditory memory, total score of visual memory and span auditory memory and the two groups had significantly difference(p<0/05), in the span visual memory. In other words, patients with MTBI has overall poorer results for all the tests than healthy people.according to the findings of this research, mild traumatic brain injury can disturb executive functions of the brain's prefrontal lobes after one year. Hence, it is suggested that in clinical and legal evaluations of the patients, this issue to be considered and both psychological and medical interventions done simultaneously to facilitate the treatment process and cognitive rehabilitation of the patients and to prevent individual, social and financial consequences and costs associated with MTBI.
