Epilepsy is only a symptomatic manifestation of its seizures, and there must be a cause of its seizures. Drug treatment can only control epilepsy without seizures or less seizures. Only by finding the real cause and treating the cause can we treat epilepsy at the root. The concept of epilepsy and convulsions is different. Convulsions are involuntary jerking or strong contractions of the whole body or local skeletal muscle groups, often causing movement and tonicity of joints. 2 or more convulsive seizures we call epilepsy, the prevalence of epilepsy in China is about 0.7%, and there are now about 9 million epilepsy patients, with about 400,000 new cases each year. There are many factors that lead to convulsions, also known as seizures. Genetic factors: idiopathic monogenic epilepsy: benign familial neonatal convulsions, juvenile myoclonic epilepsy, benign epilepsy with mesial temporal spikes, nocturnal frontal lobe epilepsy. Common genetic disorders such as phenylketonuria, cerebral lipid accumulation disorder, and cerebral leukodystrophy can have seizures. Perinatal factors: intrauterine infections, obstructed labor, birth injuries, intracerebral hemorrhage, hypoxia, jaundice, infection, and premature birth can cause seizures. Intracranial infections: such as brain abscesses can occur with seizures up to 72%; cerebral cysticercosis is 30%; the incidence of epilepsy is 25% when AIDS involves the nervous system; bacterial meningitis and viral meningitis can both have seizures or persistent epilepsy as the first symptom. Cerebrovascular disease: the incidence of epilepsy after intracranial hemorrhage is 4.6%; the incidence of epilepsy after TIA is 4.4%. Some domestic authors summarized the occurrence of epilepsy in the age group over 50 years old and found that more than 30% were due to cerebrovascular disease. Intracerebral tumors: the incidence of neurological primary tumors combined with epilepsy is about 10%; the incidence of metastases is 30%; more than 2/3 of patients with tumors involving the cerebral hemispheres can develop various types of seizures. Neurological lesions: about 1/3 of patients with Alzheimer’s disease can have seizures in combination 5% of patients with Huntington’s disease and 6% of patients with Wilson’s disease have seizures during the course of the disease. Craniocerebral trauma: the incidence of craniocerebral trauma is about 20%; the incidence of combined intracranial hematoma is about 35%; the incidence of combined depressed skull fracture is 17%; delayed epilepsy occurs in about 25% of patients with craniocerebral trauma Neurosurgery: the incidence of epilepsy after simple borehole biopsy or ventricular puncture and drainage is 9-13%, with 55% of patients after frontal lobe drainage and epilepsy occurred in 7% of patients. Epilepsy occurred in 19% of patients after craniotomy for glioma, 22% of patients after meningioma, and 21% of patients after intracranial hematoma removal. There are also poisoning, vaccination reactions, drug reactions, electrolyte disturbances, vitamin B6 dependence, and liver and kidney insufficiency. Some conditions such as prolonged television viewing, computer use, lack of sleep, overexertion, alcohol consumption, violent mood swings, and cold and fever can increase the frequency of seizures in patients with epilepsy, and these are factors that trigger seizures, not direct causes of seizures, and should be avoided. There are many causative factors for seizures, and most can identify the cause so as to guide treatment. Therefore, once a seizure occurs, one should immediately go to a hospital, have the cause examined, and treat the root cause.
