Patients with encephalopathy are the most important factors causing epilepsy: 1. congenital or developmental diseases: malformations of brain development (microcephaly, cerebral penetration malformation, cerebellar gyrus malformation), hydrocephalus, neurocutaneous syndrome (tuberous sclerosis, cerebral trigeminal neurovascular tumor) cerebral palsy, etc.; 2. craniocerebral injuries: birth injuries (intracranial hemorrhage dural lacerations, cerebral contusions), acute craniocerebral injuries (closed, open 3. infections: bacterial meningitis, brain abscess, viral meningitis or encephalitis, tuberculous meningitis or mycobacterial meningitis, tetanus, cerebral parasites or protozoa, etc.; 4. brain tumors: glioma, meningioma, cerebral leukomalacia, etc.; 5. cerebrovascular disease: cerebral aneurysm, arteriovenous malformation, intracranial hemorrhage, cerebrovascular embolism, cerebrovascular and venous thrombosis, etc, 5. Cerebrovascular disease: cerebral aneurysm, arteriovenous malformation, intracranial hemorrhage, cerebrovascular embolism, arteriovenous and venous sinus thrombosis, chronic subdural hematoma and hypertensive encephalopathy, etc.; 6. II. Toxic epilepsy: drug poisoning; food poisoning, carbon monoxide (CD) poisoning, organophosphorus poisoning, heavy metal poisoning (mercury, lead, arsenic), etc. Hypoxia. Shock, asphyxia, severe anemia, acute hemorrhage, cardiopulmonary disorders, etc. are likely to cause epilepsy. Endocrine and metabolic disorders: abnormal protein, sugar and fat metabolism; water and salt metabolism disorders (water intoxication, alkalosis, uremia, hypertonic dehydration); low blood calcium, low blood magnesium; vitamin deficiency, hepatic encephalopathy; renal insufficiency; nuclear jaundice, etc. are also causes of epilepsy. Clinical observations around the world confirm that 75%-80% of children with epilepsy can recover completely as long as they are given reasonable treatment. Therefore, it is necessary for parents with pediatric epilepsy at home to learn about recovery.
