The causes of epilepsy mainly include some congenital factors, such as pathological changes during pregnancy or childbirth, which can lead to the occurrence of epilepsy in children. In adults, epilepsy is generally secondary to severe head trauma, cerebrovascular disease, intracranial tumors, encephalitis, etc. Therefore, for patients with epilepsy, it is first necessary to actively remove various inducements and then to treat according to the type of epileptic seizures. Epilepsy mainly includes generalized seizures and partial seizures. Patients with generalized epileptic seizures can take medications such as sodium valproate and diazepam for treatment. Patients with partial epileptic seizures can take medications such as carbamazepine, oxcarbazepine, gabapentin, and levetiracetam for treatment. Generally, the symptoms of epilepsy can be effectively controlled after patients follow a standardized medication treatment regimen.

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 mild epilepsy be treated?

Mild epilepsy is treatable. If the patient is experiencing their first seizure or if the seizures are infrequent, it’s generally appropriate to observe clinically and not rush to use anti-epileptic drugs. Such patients typically experience only very mild neurological symptoms during a seizure, such as limb weakness, numbness, or facial droop. However, if the patient's seizures occur frequently, it is necessary to control the symptoms with anti-epileptic medications, which often include drugs such as levetiracetam, gabapentin, sodium valproate, and lamotrigine. Patients with mild epilepsy should also work on strengthening their exercise routines, maintaining a calm mind, and getting sufficient sleep to help prevent seizures to a certain extent. If the patient's condition worsens or becomes intractable epilepsy, surgical treatment methods may be considered to control the symptoms.

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.

What are the signs before the onset of epilepsy?

Before the onset of epilepsy, most patients do not exhibit any signs and can suddenly experience an epileptic seizure. Different types of epilepsy have different symptoms. For example, during a major seizure, symptoms can include limb twitching, eyes rolling upwards, frothing at the mouth, clenched teeth, loss of consciousness, and abnormal blood pressure, which can lead to severe falls and injuries. During a minor seizure, the patient mainly shows transient loss of consciousness, objects in hand may suddenly drop, unresponsiveness when called, and a vacant stare. Most patients do not fall, and the symptoms generally last for only a few seconds to tens of seconds. If autonomic epileptic seizures are considered, symptoms may include nausea and vomiting. Psychotic symptom seizures can present with hallucinations and delusions.

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.
