Usually, children with a history of febrile convulsions stop around the age of 5 years. Usually febrile convulsions occur because the child’s brain is not sufficiently developed and is affected by viral and bacterial infections as well as genetic factors, and abnormal discharges during fever cause rhythmic convulsions of muscles and limbs. Most children have febrile convulsions between the ages of 6 months and 3 years, and most of them have generalized seizures that are infrequent, but after the age of 5 years, the child’s brain development can be gradually improved and febrile convulsions usually do not occur again. If children still have convulsions after the age of 5, they are called complex febrile convulsions and have the possibility of epilepsy, and need to be seen immediately in the pediatric department of the hospital for a detailed examination to clarify the diagnosis. In addition, when febrile convulsions occur, parents should remain calm and quiet, prohibit all unnecessary stimulation to the child, and keep his or her airway open.
