Genetic testing for epilepsy can be done for complex febrile convulsions. Complex febrile convulsions belong to a specific type of febrile convulsions, of which only 4% of patients, may be considered to be related to genetic factors. Its main age of onset is under 6 years old, the onset time lasts more than 15 minutes, and abnormal neurological signs such as temporary paralysis syndrome may occur after the onset of the disease, which can be diagnosed by blood biochemistry and electroencephalogram. The pathogenesis of complex febrile convulsions has not been clarified, and is currently thought to be related to imbalance of neuromediators in the pediatric brain, underdevelopment of the brain, and myelin production, which results in a lowering of the threshold for convulsions in the cerebral cortex, so that the nerve cells may suddenly discharge and cause convulsions when the pediatrician develops a high fever. It may also be associated with genetic factors, but no definitive genetic mutations have been identified, so there are no relevant genetic tests for complex febrile convulsions. However, some epilepsies with complex febrile convulsions as the main manifestation, such as Dravet syndrome, can be genetically tested to determine whether there is a mutation in the SCN1A gene. It is recommended to go to the corresponding department of the hospital in time, improve the relevant examination under the guidance of the doctor, and pay attention to children’s warmth in daily life to avoid colds and fever.
