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 > or =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.
