There are no clear relevant studies suggesting delayed myelin development as a cause of epilepsy. Epilepsy can be categorized as idiopathic, cryptogenic and symptomatic according to the cause. Idiopathic epilepsy is considered to be genetically related; cryptogenic epilepsy refers to those for which no definite cause of epilepsy has been identified; symptomatic epilepsy refers to those caused by a variety of well-defined structural injuries or functional abnormalities of the central nervous system, such as traumatic brain injury, cerebrovascular disease, brain tumors, central nervous system infections, inherited metabolic disorders, cortical developmental disorders, and neurodegenerative diseases, among others. In studies related to the etiology of epilepsy, there is no clear suggestion that delayed myelin development is the cause of seizures, but delayed myelin development can be combined with other intracranial lesions, such as diffuse cerebral atrophy, which can lead to secondary epilepsy. Once the diagnosis of epilepsy is confirmed, it is important to consult a doctor in time, complete the relevant examinations, find the cause of the disease and carry out standardized treatment.
