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.

What causes benign epilepsy in children?

There are multiple causes of benign epilepsy in children, with significant genetic factors often involved. It generally occurs during a specific developmental period in childhood due to localized diseases, and the prognosis is usually good. Such seizures in children may be caused by conditions like tuberous sclerosis, cerebral trigeminal angioma, and neurofibromatosis. Intracranial infections, such as viral encephalitis, bacterial meningitis, and tubercular meningitis, can also trigger benign epilepsy in children. Therefore, once diagnosed, early intervention treatments should be initiated to prevent the symptoms from worsening. Regular follow-ups with electroencephalograms are also necessary to understand the effects of epilepsy medications and treatments.

Can epilepsy patients drink water frequently in their daily life?

Patients with epilepsy can often drink water in their daily lives, but they should avoid drinking water during the acute phase of a seizure to prevent aspiration. Patients with epilepsy generally need to take anti-epileptic drugs for a long time to prevent seizures, such as carbamazepine, oxcarbazepine, gabapentin, etc. Drinking water frequently does not affect the patient's condition. Moreover, drinking water frequently helps to dilute the viscosity in the blood and lower blood lipids, thereby preventing cerebral vascular accidents. In addition to drinking water, patients with epilepsy can also eat more fruits and vegetables, which contain abundant vitamins and trace elements that nourish nerve cells. Furthermore, patients with epilepsy should avoid climbing heights and coming into contact with dangerous environments such as ponds and lakesides.

Early Symptoms of Baby Epilepsy

The early symptoms of epilepsy in babies include excessive sweating on the head during feeding and sleep. Due to the irritation of the sweat, the child likes to shake their head, which causes friction on the back of the head, leading to hair loss over time. Additionally, the child appears restless and easily wakes up during sleep. If parents notice these symptoms of epilepsy, they should seek treatment for their child early to avoid delays and recurrent conditions.

Do you need to take medication for epilepsy long-term?

Patients with epilepsy are clinically divided into primary and secondary types. Primary epilepsy is mainly treated with medication, and most patients require long-term use of anti-epileptic drugs to control seizures. Some patients can completely control the symptoms of epilepsy with medication; if they are seizure-free for three to five years, it is referred to as clinical cure, and they may discontinue the medication. For patients experiencing primary epilepsy seizures, treatment focuses on the cause of the condition, such as common diseases like cerebrovascular diseases, including cerebral hemorrhage, cerebral infarction, brain tumors, encephalitis, brain parasite infections, and cranial trauma. After the primary disease is cured, symptoms of epilepsy may be controlled in these patients. If some patients still experience epilepsy seizures after treatment, they should continue taking long-term oral anti-epileptic drugs to control the seizures.

What causes epilepsy relapses?

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.
