The treatment of secondary epilepsy requires a two-pronged approach: on the one hand, anti-epileptic treatment is needed to reduce seizures; on the other hand, the primary cause of the disease must be actively treated, as it is the “root cause” of the disease. The general principle is “treat the symptoms if it is urgent, and treat the root cause if it is slow”. When the patient has frequent seizures and is in critical condition, the main focus should be on anti-epilepsy to stop the seizures and stabilize the vital signs as soon as possible. Oral medications are usually given, and if necessary, various routes of administration such as intravenous push, intravenous drip, intramuscular injection, enema, etc. Critical patients may need intensive care, using tracheal intubation, ventilator and other resuscitation measures. While controlling the patient’s seizures, the doctor will also use various means to try to find the cause of the epilepsy and find ways to treat the primary cause. For example, in epilepsy caused by hypoglycemia, if the blood sugar cannot be corrected, even with the use of antiepileptic drugs, the seizures will recur. In contrast, when glucose is pushed intravenously, the blood sugar rises and the seizures improve naturally.
