Abstract

OBJECTIVE
We investigated independent predictors of post-concussion syndrome after mild head injury.
METHODS
From January 2001 to December 2007, 66 consecutive patients were diagnosed as post-concussion syndrome among 331 patients with mild head injury admitted to our neurosurgical department. We reviewed retrospectively the medical records and analyzed baseline and socioeconomic data including age, sex, current smoking, alcohol consumption, level of education, employment status, marital status and types of injury. Using multivariate analysis, we evaluated possible factors associated with post-concussion syndrome after mild head injury.
RESULTS
The incidence of post-concussion syndrome after mild head injury was 19.9%. Patient's unemployed state was significantly higher among patients with post-concussion syndrome than in the control group (39.4% versus 23.4%, respectively, p=0.008) and the victims of traffic accident were more frequent among patients with post-concussion syndrome than in the control group (81.8% versus 55.1%, respectively, p<0.001). Multivariate analysis showed that unemployed state (odds ratio [OR] 2.32, 95% confidence interval [CI] 1.24-4.32, p=0.008), divorced state (OR 2.06, 95% CI 1.06-4.00, p=0.034) and the victims of traffic accident (OR 4.87, 95% CI 2.09-11.34, p<0.001) are independently associated with post-concussion syndrome after mild head injury.
CONCLUSION
Our result indicated that the victims of traffic accident, unemployed state and divorced state may be independent predictors of post-concussion syndrome after mild head injury.
