Convulsions in children can have many causes. There are genetic factors and secondary factors caused by other diseases. In some children it is a genetic factor. For children where genetic factors are considered, in some families, several people can be found with the same symptoms, or there can be a complete absence of patients with similar disorders in the family. For genetic factors to cause it can also be a new mutation or a problem of parental origin. Other congenital developmental problems may also cause convulsions, for example, if a child is born with a part of the brain that is not fully grown, there may be inappropriate synchronization of discharges, which may manifest clinically as convulsions. Other children may have previous intracranial hemorrhage, infection, etc., and brain damage occurs, leaving sequelae, which can also occur in convulsions. Some children have metabolic diseases that can also be the cause of convulsions. Other children are simply sensitive to heat and have convulsive seizures when their body temperature rises rapidly. Other children have electrolyte disorders, and some have brain damage from toxins, all of which are associated with the possibility of convulsions. If a child has a seizure, it is important to detect and treat the seizure as soon as possible to find the cause of the seizure. Blood biochemistry, electroencephalograms, and imaging tests can help to find the cause of the seizure.
