Some patients may have only mouth twitching, facial muscle twitching or eyelid muscle twitching, while others may have only focal limb twitching or even only finger twitching. Small seizures are mainly treated with medication, surgery and neuromodulation therapy. 1. medication: patients with unclear etiology or recurrent seizures can be controlled with medication under the advice of the doctor, commonly used anti-epileptic drugs such as carbamazepine and oxcarbazepine. 2. surgery: for patients with organic lesions in the brain and poor results of medication, surgical treatment can be recommended by the doctor. 3. Neuromodulation therapy: The most commonly used neuromodulation therapy is vagus nerve stimulation, which is a new type of treatment for drug-resistant epilepsy that cannot be controlled even after 1-2 years of combined drug therapy, and drug-resistant epilepsy that is not suitable for surgical removal of intracranial lesions. In addition to the above treatments, if the petit mal seizures are caused by central nervous system infection, the primary cause needs to be actively controlled along with antiepileptic drug treatment.
