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.

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.

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.)

What are the dietary precautions for epilepsy?

People with epilepsy should avoid consuming stimulating beverages such as cola, Sprite, Red Bull, and coffee. They should eat more vegetables and fruits and less spicy and stimulating foods, paying attention to these dietary recommendations. Additionally, maintaining a regular lifestyle is important; avoiding prolonged use of electronic devices is advised as these, along with previously mentioned beverages like cola and Red Bull, can overexcite the brain and trigger epileptic seizures. It is also imperative to take anti-epileptic drugs regularly under the guidance of a doctor and not to miss any doses.

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.

What causes epilepsy in the elderly?

If a patient has no history of epilepsy but begins to experience epileptic seizures in old age, it is generally secondary epilepsy, also known as symptomatic epilepsy. All patients should have a clear cause, but with current diagnostic techniques, it is not always possible to find the cause. If the cause cannot be identified, it is called cryptogenic epilepsy. In such cases, it is generally necessary to improve diagnostic methods, such as cranial magnetic resonance imaging (MRI) and cranial magnetic resonance angiography. The most common causes of epilepsy in the elderly are generally cerebrovascular disease, brain trauma, or encephalitis, and in some cases, brain tumors. Any disease that causes brain cell damage can potentially cause symptomatic epileptic seizures. If all imaging examinations fail to reveal any abnormalities, regular follow-ups are necessary to monitor for early-stage tumors that may not be detectable on imaging tests. Meanwhile, antiepileptic treatment should be administered, and routine blood tests, liver, and kidney functions should be regularly monitored.
