Convulsions can be caused by epilepsy, and when they are caused by epilepsy, clinically they include primary epilepsy and secondary epilepsy. Primary epilepsy is mainly treated with antiepileptic drugs, which are commonly used clinically, including traditional antiepileptic drugs and new antiepileptic drugs. Traditional antiepileptic drugs mainly include carbamazepine, phenytoin sodium, sodium valproate, phenobarbital, ethosuximide and clonazepam. Newer antiepileptic drugs are commonly used clinically, such as levetiracetam, topiramate, lamotrigine and gabapentin. In the case of secondary epilepsy, patients with severe convulsive seizures can be given symptomatic treatment, while the cause can be treated. Common causes of secondary epilepsy include cranial tumors, infectious diseases of the central nervous system, including encephalitis and meningitis, and cerebrovascular diseases, such as cerebral hemorrhage and massive cerebral infarction. Certain systemic diseases, such as systemic lupus erythematosus or diabetes mellitus, may also present with convulsive seizures. Depending on the different causes mentioned above, treatment of the cause is carried out accordingly. In case of low calcium, the patient may also experience convulsions. If the patient’s blood calcium is lowered, he/she can take oral calcium, Diclofenac, or in severe cases, calcium gluconate can also be injected intravenously for calcium supplementation.
