[Forensic psychiatric cases of 534 mental disorders caused by traumatic brain injury].
OBJECTIVE
To analyze the types of mental disorders caused by traumatic brain injury and the optimal time for forensic psychiatric appraisal. To explore the relationship between the degree of traumatic brain injury, the time of appraisal and the grade of intellectual deficiency.


METHODS
Five hundred and thirty-four forensic psychiatric cases of mental disorders caused by traumatic brain injury were retrospectively analyzed.


RESULTS
In the types of mental disorders caused by traumatic brain injury, the most cases were diagnosed as organic mood disorders (51.1%), following organic neurosis-like syndrome (24.0%) and organic intellectual deficiency (18.0%). For the disability grades, the most cases were the level VIII and IX disability grades, 219 cases (41.0%) and 177 cases (33.1%), respectively. The degree of brain injury and the degree of intelligence defection according to WAIS-RC were higher in intellectual deficiency group compared with non-intellectual deficiency group (P < 0.05). The grade of disability correlated with the degree of brain injury, the result of WAIS-RC, the result of cerebral CT scanning, and the grade of brain electrical activity mapping (BEAM) abnormality (P < 0.05). Nevertheless, the degree of intellectual deficiency did not correlate with appraisal time and the degree of brain injury (P > 0.05).


CONCLUSIONS
The factors influencing intellectual deficiency are complex. The findings of objective examination including cerebral CT scanning, BEAM, WAIS-RC and others should be considered as important indexes for disability evaluation.
