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?

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.

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.

Can acquired epilepsy be treated?

Acquired epilepsy can be treated. Most cases of acquired epilepsy are due to some organic lesions, also known clinically as secondary epilepsy, primarily treated by addressing the underlying disease. Common clinical conditions include brain organic lesions such as cerebral hemorrhage, cerebral infarction, brain tumor, encephalitis, and brain parasitic infections. Systemic diseases like diabetes and hyperparathyroidism can also lead to epilepsy. If epilepsy persists or if there is a major epileptic seizure, it can lead to brain cell hypoxia and even brain edema in severe cases. When necessary, treatments to protect the brain and reduce intracranial pressure are required. Medications for brain protection include Cytidine Diphosphate Choline and Lacosamide, while drugs to lower blood pressure mainly include Mannitol, Glycerol Fructose, and Furosemide. Most patients potentially can be carefully cured through the treatment of the underlying disease, and if seizures persist after the treatment of the primary disease, antiepileptic drugs should be administered. (The use of medications should be under the guidance of a physician.)

Can epilepsy patients drink water frequently in their daily life?

Patients with epilepsy can often drink water in their daily lives, but they should pay attention to the amount of water they drink and not consume too much at once. Drinking too much water in a short period can lead to increased urination, and an increase in the frequency of urination could potentially trigger a seizure. Additionally, patients should try to reduce their water intake during a seizure episode. Drinking water during a seizure can easily cause choking or even suffocation. Therefore, patients with epilepsy need to pay attention to adjusting their diet and lifestyle. Moreover, patients need to take long-term medication to prevent seizures, including commonly used drugs such as carbamazepine and sodium valproate. In hot weather, patients with epilepsy still need to hydrate appropriately; otherwise, dehydration and low blood pressure can occur, which can also easily trigger a seizure.

What are the prodromal symptoms of epilepsy?

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.
