Hwang, Na, Kim, Lee, and Jung: Alteration of Cognitive Function in Mild Traumatic Brain Injury Patients Grouped by Subjective Depression

Abstract

Objectives

To examine the association of subjective depressive symptoms and cognitive dysfunction in patients with mild traumatic brain injury (mTBI).

Methods

36 patients with mTBI without structural abnormality in the brain imaging study were recruited. Participants were subdivided into two groups by a cutoff score of 70T in the Beck Depression Inventory (BDI). Cognitive functions including intelligence, memory, and executive function were significantly lower in the <70T group compared to the ≥70T group. In addition, BDI scores were negatively correlated with performances in most of the neuropsychological tests.

Results

Patients group who scored 70T or more in the BDI showed significantly lower scores in most items of the neuropsychological tests.

Conclusion

High subjective depression is associated with low neuropsychological performance in mTBI.
