Evaluation the Cognitive and Behavioral Inhibition of Patients with Mild Traumatic Brain Injury

Inhibition, which is defined as onechr('39')s ability to monitor and control responses, is one of the most important executive actions that become defective after a traumatic brain injury. Due to the direct effect of this ability on peoplechr('39')s quality of life, the purpose of this study was to compare the cognitive and behavioral inhibition in patients with Mild Traumatic Brain Injury (MTBI) one year after their injury with healthy individuals.

In this descriptive causal-comparative study, which was conducted from February 2017 to October 2018, 48 male patients with MTBI in the age range of 30 to 55 years old who were hospitalized in the ICU of Shohadaye Haftome Tir Hospital in Shahr-e-Rey and in the Baqiyatallah Hospital in Tehran during the past year as a test group and 64 healthy men with a similar age range as a control group were selected by convenience sampling method. Both groups were evaluated by stroop test and collected data were analyzed by SPSS 21 software using multivariable analyze of variance.

The mean scores of congruent reaction time, incongruent reaction time and congruent error number (p<0.05), and incongruent error number, score of interference and error responses sum (p<0.01) in patient with MTBI was significantly higher than healthy people.

MTBI after one year can disrupt the function of the frontal lobe of the brain and affect the executive functions under the command of this area, especially on the cognitive and behavioral inhibition of patients.
