Correlative factors for organic psychotic symptoms in patients following traumatic brain injury.

Objective: To investigate the correlative factors for organic psychotic symptoms following traumatic brain injury (TBI).

Methods: In the current study, 391 subjects who had undergone forensic identification of the organic mental disorders due to TBI were included, both the demographic and post-traumatic information collected. The relevant data were statistically analyzed in those confirmed as organic psychotic syndrome according to Chinese Classification of Mental Disorders 3rd version (CCMD-3).

Results: Fifty-two subjects (13.3%) were identified as organic psychotic symptoms. The chi-square test showed that the detectable organic psychotic symptoms were associated with the marriage status, damage nature, injury severity and treatment, and the multivariate logistic regression analysis revealed good fitness of treatment and injury severity with the regression model (OR = 0.044, 95% CI: 0.017-0.114; OR = 2.145, 95% CI: 1.201-3.832, respectively).

Conclusion: The risks of organic psychotic symptoms following TBI can be involved in the alternative of craniotomy for the cases with trauma and moderate brain injury.
