When a child is diagnosed with epilepsy, parents are often overwhelmed and filled with anxiety, self-blame, and panic, “Why did the child get the disease?” “Why is my child sick?” “Did I receive computer radiation during my pregnancy? “, various questions plague young parents. In general, the occurrence of epilepsy is the result of the interaction of intrinsic genetic factors and external environmental factors within the individual, and the etiology of each epileptic patient includes both factors, only the proportion of each is different. The etiology of epilepsy has been previously classified as idiopathic (with no identifiable cause other than a possible genetic susceptibility to epilepsy), symptomatic (caused by a known brain lesion, including organic changes in the brain or biochemical metabolic disorders), and cryptogenic (where no structural or biochemical cause can be found based on current knowledge and technology, but is suspected to be symptomatic). With advances in medical technology and further understanding of epilepsy, the International League Against Epilepsy (ILAE) Working Group on Classification has classified epilepsy into 6 major categories: genetic, structural, metabolic, immunological, infectious, and of unknown origin. The genetic factors that cause epilepsy are: fragile X syndrome, trisomy 18, Angelman syndrome, Dravet syndrome, etc.; structural factors that cause epilepsy: tuberous sclerosis, Sturge-Weber syndrome, neurofibromatosis, gray matter heterotopia, cerebral cleft malformation, etc.; metabolic factors that cause epilepsy: organic aciduria, pyridoxine dependence The epilepsies caused by immunological factors: multiple sclerosis, anti-NMDAR encephalitis, anti-Hu antibody-associated encephalitis, etc.; epilepsies caused by infectious factors: viral encephalitis, septic encephalitis, etc.; and some epilepsies whose causes cannot be found by current medical technology are classified as having unknown causes.
