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.

Precursors to epileptic seizures in children

The majority of childhood epilepsy seizures occur without any precursors, as they arise and cease suddenly with stereotyped movements. However, some seizures are preceded by prodromes, such as sudden onset of consciousness disturbances, or fainting symptoms. Other seizures can present with motor dysfunctions, displaying sudden weakness or fatigue in certain limbs, followed by an epileptic attack. Additionally, some may experience abnormal sensations, such as numbness in a specific area or visual disturbances, including sudden flashes or even visual distortions, leading to convulsive seizures.

How is epilepsy treated?

Epilepsy treatment can be divided into the following aspects: First is etiological treatment. If epilepsy is caused by tumors or cerebrovascular diseases, surgical removal of the lesion can relieve epilepsy, but seizures often still occur, so medication must not be stopped. Secondly, pharmacological treatment is necessary for epilepsy induced by unclear causes or genetic metabolic diseases. Treatment involves taking and adjusting medications under medical guidance, based on different types of seizures and individual patient circumstances. Additionally, for some cases where the cause cannot be clearly identified and no epileptic foci are found, functional surgery can be performed for treatment.

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.

Why does epilepsy occur at night?

Epilepsy that occurs at night is called sleep-related epilepsy. There are many reasons for this phenomenon, such as excessive fatigue, irregular sleep, menstrual onset, anxiety, depression, and more. Additionally, some patients exhale more carbon dioxide during sleep, causing hyperventilation and internal environmental imbalances, which can easily lead to abnormal discharges of brain neurons. When some patients experience symptoms of epilepsy at night, timely intervention and treatment are needed. First, patients should develop a good lifestyle, go to bed on time, get up on time, avoid staying up late, and avoid excessive fatigue. Furthermore, targeted medication should be given to prevent the onset of the condition. Common medications include lamotrigine, levetiracetam, carbamazepine, and sodium valproate. Besides, patients also need to maintain a good mindset and avoid tense and anxious emotions that could exacerbate symptoms.
