The prodromal symptoms of epilepsy are diverse, generally involving movement, sensation, and mood. Some patients may experience transient numbness or weakness on one side of their body prior to a seizure, while others may have hallucinations and atypical mental or behavioral changes. However, these symptoms are not necessarily indicative of an impending seizure. When such symptoms occur, it is crucial to consider the possibility of an epilepsy attack, and patients should promptly visit the neurology department of a hospital for a thorough examination, including an electroencephalogram (EEG). If the EEG shows significant abnormalities such as spikes, sharp waves, slow waves, spike-and-wave complexes, or sharp-and-slow wave complexes, it suggests the potential for an epileptic seizure. In such cases, preventive medication should be administered promptly, such as carbamazepine or sodium valproate.

What are the early symptoms of epilepsy in children?

Epilepsy is a particularly common chronic disease in life. If the brain is underdeveloped and there are neurological disorders, it can cause epilepsy. What are the early symptoms of childhood epilepsy? The manifestations of a child's epileptic seizure are diverse, but all have the characteristics of sudden onset, sudden cessation, and periodic attacks. Common types in children include major seizures, absence minor seizures, and benign childhood epilepsy. During a major seizure, the child suddenly loses consciousness, breathing stops, the complexion turns cyanotic, the pupils dilate, the limbs stiffen, and the hands clench into fists, then switching to paroxysmal convulsions, foaming at the mouth, with the attack generally lasting 1-5 minutes. Children with absence seizures appear to suddenly lose consciousness, stop their activities, and stare upward or roll their eyes, but they do not fall down or convulse, lasting 1-10 seconds, with consciousness quickly recovering after the attack. Benign childhood epilepsy seizures often involve twitching of one side of the face, lips, and tongue, possibly accompanied by abnormal sensations in those areas, inability to speak, and drooling, typically with clear consciousness, and more frequently occurring at night.

What can severe epilepsy lead to?

Severe epilepsy can cause many complications, such as cerebral edema, brain herniation, upper gastrointestinal bleeding, etc. Therefore, severe epilepsy can seriously threaten the patient's life. If the patient's epilepsy is not controlled in time, it can easily lead to a state of status epilepticus. Status epilepticus is a very dangerous central nervous system disease. Patients may experience sudden respiratory and circulatory arrest and uncontrollable massive gastrointestinal bleeding. For severe epilepsy patients, it is necessary to promptly administer medications such as diazepam and sodium valproate to terminate the seizures. If status epilepticus occurs, the patient needs to be urgently sent to the ICU for observation and treatment, and effective interventions for various complications must be provided. For example, in the case of cerebral edema caused by epilepsy, medications such as mannitol and glycerol fructose are needed to dehydrate and reduce intracranial pressure. If epilepsy causes acute upper gastrointestinal bleeding, treatments to suppress acid, stop bleeding, and maintain blood pressure are required.

What is childhood epilepsy?

Epilepsy is a persistent brain disease characterized by recurrent epileptic seizures, abnormal perceptions, and associated neurological, cognitive, psychological, and social issues. An epileptic seizure refers to sudden, brief symptoms and signs caused by excessive and abnormal discharges of brain neurons. Depending on the affected brain functional areas, clinical manifestations can vary, including disturbances in consciousness, motor functions, sensory abnormalities, as well as psychiatric and autonomic nervous system dysfunctions. It is important to note that epileptic seizures and epilepsy are two distinct concepts.

What are the symptoms of epilepsy in children?

Epilepsy is a chronic brain disorder caused by various etiologies, characterized by repetitive, episodic, and transient central nervous system dysfunction due to abnormal and excessively synchronized discharges of brain neurons. The clinical manifestations of childhood epilepsy are complex and varied, commonly including loss of consciousness, localized or generalized muscular rigidity or clonic convulsions, and sensory abnormalities; there may also be abnormal behaviors, emotional and perceptual disturbances, memory changes, and autonomic nervous system dysfunction.

Can children's epilepsy be effectively treated?

Can childhood epilepsy be cured? Firstly, it depends on the type of epilepsy. If the symptoms are not very severe, the frequency of convulsions is low, and comprehensive exams such as brain MRI and genetic testing show no problems, and the child's intellectual development is normal, then this type of epilepsy might be curable. Generally, after 2 to 3 years of effective antiepileptic drug treatment and then gradually discontinuing the medication if there are no further seizures, the condition can usually be controlled. However, some types of epilepsy are associated with underlying diseases, such as cerebral palsy, inherent metabolic genetic disorders, poor brain development, or organic brain lesions. The treatment outcomes for these types of epilepsy are not good, and they are generally difficult to control.
