The nerves of the human brain are well myelinated at the age of six, and theoretically, no more febrile convulsions will occur. Because the brain nerves are like electric wires, myelin is like the insulation rubber outside the wires, and imperfect development before the age of six is prone to leakage, i.e., it is prone to febrile convulsions. After six years of age, myelin sheathing is perfect, that is, the wire insulation system is perfect, and no more febrile convulsions should be found. If febrile convulsions still occur after the age of six, the brain is not well myelinated and will mostly be accompanied by a relative lag in motor or cognitive level, so a neuropsychological developmental assessment should be performed promptly at the hospital. If there is a general backwardness, medications can be given to promote brain neurodevelopment, such as oral Jin Aocong capsules and or cerebral protein hydrolysate, rat nerve growth factor, etc.
