Brain metastasis should refer to brain metastasis tumor, brain metastasis tumor can cause patients to have frequent convulsions, appearing once an hour, which can be treated by antiepileptic drugs, surgery and other ways. Brain metastasis occurs when tumors in other parts of the body, such as lung cancer, liver cancer, breast cancer, metastasize to the brain. Brain metastasis can compress normal brain tissues, which can cause abnormal neuron discharges, leading to secondary epilepsy, such as frequent seizures, which can occur once an hour. For treatment, if it is a single brain metastasis and the patient’s primary tumor has been relatively well controlled, it can be treated by surgery; if it is a multiple brain metastasis, the epilepsy can be controlled by using drugs such as carbamazepine, phenytoin sodium, and clonazepam under the guidance of the physician, and continue to be treated for the primary tumor. If the diagnosis of brain metastases is confirmed and frequent convulsions occur, timely consultation and treatment should be sought.
