To investigate the diagnostic classification and epidemiological characteristics of secondary epilepsy post-craniocerebral trauma.

The clinical data of one thousand seven hundred and ninty-nine patients with craniocerebral injury were retrospectively analyzed.The correlation of craniocerebral injury severity to characteristics of injury and traumatic epilepsy, the differences of onset time of different types of craniocerebral injury were analyzed.The diagnostic classification and epidemiological characteristics of traumatic epilepsy were also analyzed in combination with clinical data.

The rate of super early epilepsy craniocerebral injury rate was as high as 29.8%.After a week, a month or three months, it fell to 12.4%, 6.7% and 5.2% respectively.The incidence of severe head injury(GCS: 3~8 points) epilepsy was 19.5%, which was significantly higher than that of light or moderate duty craniocerebral injury(GCS: 9~12, 13~15 points) patients.The rates of penetrating wound surgery and non-surgical patients with epilepsy were 36.0%, 15.9% and 2.5% respectively.The rate of open craniocerebral injury incidence of epilepsy was 26.5% and the rates of the impuberism groups and the adult group traumatic epilepsy were 14.1%, 3.5% respectively.The brain injury of epilepsy patients mainly located in the brain functional areas such as the frontal lobe and parietal and occipital lobe after diffuse brain cortex injury.

There are obvious differences in the incidence of traumatic epilepsy during super early, early and late period of craniocerebral injury.The incidence of severe head injury is significantly higher than that of the light and the middle.The rates of penetrating injury and the open injury are obviously higher than those of the closed craniocerebral injury.The impuberism has higher epilepsy risk rate.The rate of functional areas of brain injury epilepsy is significantly higher than that of the non-functional.
