Epilepsy is a common neurological disorder, with the highest incidence in children under the age of one. The prevalence of epilepsy in China ranges from 0.4% to 0.7%, with nine million epilepsy patients, of which six million have active epilepsy. Every day, there are 400,000 new cases of epilepsy, with a prevalence of up to 1% among those aged sixteen and under. There are many children with epilepsy, experiencing various types of seizures, each with its own characteristics, but all share the features of sudden onset, abrupt cessation, and periodicity.

What causes epilepsy relapses?

Epilepsy is a clinical syndrome caused by highly synchronized abnormal discharges of brain neurons due to various reasons. Clinically, it is characterized by episodic, transient, repetitive, and stereotyped manifestations, making recurrence a characteristic of the disease itself. The location of the neurons with abnormal discharges and the range of the abnormal discharge waves vary, leading to different forms of seizure symptoms in patients. These can manifest in various ways, including sensory, motor, consciousness, psychiatric, behavioral, and autonomic nervous system dysfunctions, and may occur simultaneously. Each seizure and each type of seizure process is referred to as an epileptic seizure. Of course, a patient can experience one or several types of epileptic seizures, thus, recurrence is a characteristic of epilepsy itself.

What are the symptoms of epilepsy in children?

Common symptoms of epilepsy in children generally include sudden convulsions. During a convulsion, the typical manifestations are tightly closed or staring eyes, rolled-up eyeballs, clenched teeth, twitching at the corners of the mouth, frothing at the mouth, head and neck thrown back, and repetitive flexing or rigid shaking of the limbs. Generally, these can last for a few minutes, or vary from several seconds to ten minutes. Of course, there are also focal seizures, such as twitching of one side of the body, or absence seizures. Some infantile spasms are characterized by jackknife movements, occurring in clusters, with each display being different. The symptoms described earlier are typical of a generalized tonic-clonic seizure.

Is epilepsy easy to treat?

Epilepsy is a disease for which the cause can be identified in some patients, while in others it may remain unknown. Initially, it is important to investigate the cause of epilepsy. Moreover, if an individual experiences multiple seizures, medication intervention becomes necessary. The primary goal of drug treatment for epilepsy is to control it and prevent further seizures, since each seizure can cause brain cell damage, potentially leading to long-term effects like memory decline and slower reaction times. Therefore, active control of epilepsy through medication is crucial. Whether epilepsy can be completely cured depends on its underlying cause. In some cases, identifying and eliminating the cause may prevent further seizures. However, for some patients, even if the cause is identified, such as a past stroke or tumors that induce epilepsy, seizures may continue even after the tumor is removed. Meanwhile, for epilepsy of unknown origins, the approach is to control the condition using medication to minimize the occurrence of seizures as much as possible, though it is not guaranteed that seizures will not happen again in the future.

What causes benign epilepsy in children?

There are multiple causes of benign epilepsy in children, with significant genetic factors often involved. It generally occurs during a specific developmental period in childhood due to localized diseases, and the prognosis is usually good. Such seizures in children may be caused by conditions like tuberous sclerosis, cerebral trigeminal angioma, and neurofibromatosis. Intracranial infections, such as viral encephalitis, bacterial meningitis, and tubercular meningitis, can also trigger benign epilepsy in children. Therefore, once diagnosed, early intervention treatments should be initiated to prevent the symptoms from worsening. Regular follow-ups with electroencephalograms are also necessary to understand the effects of epilepsy medications and treatments.
