In this causal-comparative study, 15 patients with traumatic brain injury with an age range of 20 to 60 years who were hospitalized in the past 3 months to a year as the experimental group and 15 healthy people from the normal community of Rasht city as companions Referees to specialized centers with an age range of 30 to 60 years were voluntarily selected as a control group by purposive sampling. The results of the Iowa gambling task test to measure decision-making in risk-taking conditions showed that the two groups do not have a significant difference in this regard. To evaluate the personality of the patients after the injury, the Iowa Personality Questionnaire was given to the companions of the patients to rate the personality characteristics of the patient before and after the injury.
