BACKGROUND: It is well-known that severe brain injury can make people susceptible to psychological symptoms. However, mild traumatic brain injury (MTBI) is still open for discussion.
Objectives: This study aimed to compare psychological symptoms of MTBI patients with those without MTBI considering demographic auxiliary variables.
Patients and Methods: This prospective cohort study was conducted on 50 MTBI patients and 50 healthy subjects aged 15 - 65 years. Psychological assessment was carried out six months post-injury using a series of self-report measures including the brief symptom inventory (BSI) scale. Other information of the individuals in the two groups was recorded prospectively. Data were analyzed using the chi-square test, t-test, and multiple linear regression tests.
Results: There was a significant difference between the MTBI patients and healthy subjects in all subscales and total score of BSI. Our findings showed that obsession-compulsion and anxiety subscales were significantly more common in the MTBI patients than in the healthy subjects. Also, multivariate regression analysis six months post- injury showed that head trauma and substance abuse can have an effect on psychological symptoms.
Conclusions: Mild traumatic brain injuries despite of the normal CT scan and history of substance abuse are closely related to psychological symptoms. Therefore, it is recommended that patients with brain trauma 6 months post-injury and subjects with a history of substance abuse be evaluated for psychological distress to support better rehabilitation.
