When it comes to epilepsy, I believe we are all familiar with the many triggers of epilepsy. Epilepsy is a chronic disease with a long treatment process and a high incidence, and according to the cause of onset, epilepsy can be divided into primary epilepsy and secondary epilepsy. Primary epilepsy is epilepsy in which no obvious clinical cause can be found, that is, from the patient’s medical history, physical examination, laboratory tests, imaging examinations, etc., it is not yet possible to find the exact location or the exact structure within the brain where the lesion exists, nor can any other obvious cause be found. Secondary epilepsy is epilepsy in which the true cause of the seizure has been found within the brain. We all know that excessive cortical discharges are the direct cause of the onset of epilepsy. Then, the common underlying causes of epilepsy are: 1. congenital disorders: congenital hydrocephalus, callosal hypoplasia, cerebral cortical hypoplasia, congenital cerebral palsy, chromosomal abnormalities, etc. 2, fetal brain injury: there are structural brain lesions in the neonatal period and infancy, of which birth injury is also a major cause of epilepsy, brain contusion, edema, hemorrhage and infarction during birth can also lead to local cerebral sclerosis, cerebral palsy. Several years later the lesion is formed. 3, cerebrovascular disease: In addition to cerebrovascular malformations and aneurysms, which cause seizures at a younger age, cerebrovascular epilepsy is mostly seen in middle-aged and elderly people. Both hemorrhagic and ischemic cerebrovascular disease can cause epilepsy. Brain tumors: In addition to traumatic brain injury, brain tumors are a common cause, especially slow-growing oligodendrogliomas, meningiomas, astrocytomas and so on. They are more common in middle age and are an important cause of secondary epilepsy. 5, brain infection: various kinds of encephalitis, meningitis, brain abscesses in the acute phase easily cause convulsions, after healing the formation of scar and adhesions may also become epileptic foci, parasitic diseases such as cerebral schistosomiasis, cerebral pulmonary schistosomiasis, cerebral cysticercosis and other often cause epilepsy. 6, acquired brain injury: youth, adulthood, traumatic brain injury is an important cause, it is an important reason for the occurrence of epilepsy, related to the location and degree of injury. The sequelae of brain injury, some in weeks, months and years before epilepsy begins to occur, the injury into the program is not the same. 7, nutritional and metabolic diseases: rickets in children, hypoglycemia, diabetes, hyperthyroidism vitamin B6 deficiency in adults. 8, poisoning: lead, mercury, carbon monoxide poisoning, and systemic diseases such as hepatic encephalopathy, hypertensive syndrome, acute nephritis, uremic syndrome, etc., can occur epilepsy. 9, degenerative diseases: such as tuberous sclerosis, Alzheimer’s disease, etc. The above is the “causes of epilepsy” related to the introduction, I hope you play a certain help. The early cure of epilepsy can not only reduce the physical harm caused by seizures, but also reduce the psychosocial harm caused by seizures.
