The correlated factors of mental disorders in patients with brain injury were analyzed using t-test, chi-square test, and logistic regression analysis.Results:A) The morbidity rate of mental disorders in patients with brain injury was 74.6%(179/240),28.7% of these subjects suffered from organic amnesic syndrome, 24.6% organic neurotic syndrome,22.9% organic personality change,19.6% organic intellectual impairment,17.1% organic mood disorders, and 14.2% organic psychotic symptoms. B) The mental disorders in patients with brain injury were correlated with education level, nature and severity of brain injury, left frontal lobe injury, left temporal lobe injury, multiple lobes of brain injury subdural hematoma. The mental disorders in patients with brain injury were negatively correlated with claim of compensation. C) There were different correlated factors in different type of mental disorders:organic intellectual impairment was correlated with severity of brain injury, and organic amnesic syndrome was correlated with education level. D) In the mild and moderate group, the most common CCMD-3 diagnoses were organic intellectual deficiency, and severe group were organic neurosis-like syndrome.
