Does brain injury cause the symptoms of epilepsy?

summary

Epilepsy is a chronic recurrent transient brain dysfunction syndrome, characterized by recurrent seizures caused by abnormal discharge of brain neurons, which seriously affects the daily life of patients. Epilepsy after traumatic brain injury is one of the most serious complications. Does brain injury cause the symptoms of epilepsy? Let's talk about it

Does brain injury cause the symptoms of epilepsy?

Traumatic epilepsy is mainly characterized by large seizures and localized seizures. The children who have frequent seizures for a long time but can not control them may have the symptoms of slow response, mental retardation and dullness. About 1 / 3 of late traumatic epilepsy is temporal lobe epilepsy with psychomotor seizures, and about half of them are localized motor seizures or generalized seizures.

Usually, the location of brain tissue injury is consistent with the location of post-traumatic epilepsy, and the clinical manifestations depend on the involved cortex and subcortical area: the prefrontal lesions are mainly generalized seizures; The lesions in the anterior and posterior central gyrus of the cerebral cortex and its vicinity were mainly localized motor seizures, Jackson seizures and generalized spastic seizures, and partial status epilepticus was also seen; Lesions in the central and parietal lobes often cause motor or sensory seizures in the contralateral limbs; Temporal lobe lesions often cause psychomotor seizures; Occipital lobe lesions often show visual seizures.

The incidence of epilepsy is about 5%, especially in children under 5 years old. There are two characteristics of early post-traumatic epilepsy in children: even mild brain injury can induce seizures; Even if the primary brain injury is not serious, it is also prone to status epilepticus.

matters needing attention

(1) Keep respiratory tract unobstructed（ 2) Ensure that patients are not hurt by sharp, hot objects or moving machines（ 3) Dental pads can be inserted between upper and lower teeth before the onset of ankylosis. Endotracheal intubation and muscle relaxant can be used in patients with very complex major seizures (especially those with blood oxygen < 85% or GCS score < 7).
