Epilepsy is a common syndrome of the nervous system. It is caused by recurrent abnormal brain cell discharges that manifest as sudden, temporary brain dysfunction. This abnormal discharge is not felt by the patient and not visible to others, but can be recorded by EEG. The most common clinical symptom is convulsion (jerking), a sudden loss of consciousness, generalized tonicity, stiffness, or twitching of the limbs during a seizure. There are also many patients with epilepsy who do not have convulsions at the onset of the seizure but present with fainting, immobility, abnormal behavior, emotional or mental abnormalities, and some patients present with symptoms of vegetative dysfunction such as abdominal pain, headache, and vomiting. There are many different types of epilepsy and a variety of symptoms, and epilepsy cannot be diagnosed based on only one manifestation. For example, convulsions are a common symptom of epilepsy, but there are many causes of convulsions, such as high fever, hypoxia, low blood calcium, low blood sugar, etc., which may cause convulsions. None of these conditions can be diagnosed as epilepsy. The physician has to take a detailed history, physical examination, and perform necessary laboratory and laboratory tests (e.g., EEG) to confirm the diagnosis, and sometimes even experimental treatment is required to make the diagnosis. Recurrent seizures are an important feature of epilepsy. Although there are various forms of seizures, each seizure is similar for each patient, i.e. stereotypy. Only one seizure cannot confirm a diagnosis of epilepsy; at least two seizures are required to be considered epilepsy. Epilepsy is a chronic disease, and a few cases are difficult to treat or even extend for life, but most patients with epilepsy can be treated or have their symptoms improved with long-term, reasonable regular treatment. Can epilepsy be cured? For epilepsy, a patient is said to be cured when he or she stops having seizures after reasonable and patient treatment. Secondly, the cure of epilepsy is conditional and needs to be observed over a longer period of time. It is irresponsible and dangerous to rashly declare that a patient is cured if he or she has no seizures after 2 to 3 months of some kind of treatment. In recent years, the level of diagnosis and treatment of epilepsy has been greatly improved, and antiepileptic drugs have been continuously developed, which has led to a great improvement in the treatment of epilepsy. Some foreign studies point out that in addition to drug factors, there are also some factors related to the following. The first is the cause of the disease. If the epilepsy is caused by acute head trauma, when the trauma is cured, the epilepsy can also improve, but if the epilepsy is caused by brain tumor or cerebrovascular disease, there are often still seizures after the tumor is removed. If the epilepsy is caused by congenital abnormal brain development, the prognosis is also bad. In addition, the prognosis varies between different types of epilepsy. In the case of aphasic petit mal seizures, the number of seizures gradually decreases with age, and about half of patients stop having seizures completely by adolescence. In the other type of epilepsy, infantile spasms, the prognosis is very poor, and most of them will turn into frequent or long duration of each seizure, and the prognosis is not good. In addition, the age of onset is also an important factor in the prognosis, with the younger the age, the worse the prognosis, and those with onset of seizures during the neonatal period often causing death. Even if the patient survives, various neurological sequelae are often left behind.
