Seizures in patients with epilepsy, mostly seen in patients with tonic clonic seizures, may be accompanied by symptoms of eyes hanging up, twitching of limbs and foaming at the mouth. Some patients may lose consciousness before the disease and are treated mainly with oral sodium valproate, and carbamazepine may also be applied. Epilepsy includes primary and secondary epilepsy, primary epilepsy refers to epilepsy with an unclear cause and secondary epilepsy refers to epilepsy with a clear cause. Common epilepsies include tonic clonic seizures, compulsive seizures, clonic seizures, and disoriented seizures. If the patient has a single seizure, antiepileptic medication is not required, and antiepileptic medication is chosen for more than two seizures. Commonly used antiepileptic drugs include sodium valproate, carbamazepine, phenytoin sodium, phenobarbital, ethosuximide, and clonazepam. Sodium valproate is a broad-spectrum antiepileptic drug that is indicated for all types of seizures. In the case of secondary epilepsy, common causes include cranial tumors, cerebrovascular disease, and also in patients with infectious diseases of the central nervous system, such as encephalitis, which are treated primarily for the cause.
