Clinical analysis of the factors leading to epilepsy after craniocerebral injury

Objective To analyse the epileptogenic factors according to the features of 39 patients with epilepsy among 402 patients with head injury.Methods Thirty-nine cases who suffered epilepsy were selected from 402 patients with head injury.The clinical factors that related to the onset of epilepsy in 39 cases were analysed.Result The onset of epilepsy after head injury was in close relation to the factors which include the degree of head injury and open head injury.The early onset of epilepsy was closely related to the contusion and laceration of brain and the intracranial hematoma.The delayed epilepsy was in closely related to solftening focus of brain after head injury.Conclusion The early epilepsy is triggered by the elevated excitabilitv of nerve cells primarily caused by the contusion and laceration of brain and the intracranial hematoma.The delayed epilepsy is caused by the abnormal discharge of epileptogenic focus formed by brain solftening focus and scar.
