Fever in babies is a cause of anxiety for parents who are deeply afraid that it will cause convulsions and subsequently seizures. Since the brain of a pediatrician is not as stable as that of an adult, the stimulation of high temperature may lead to convulsions. So, what are the causes of fever convulsions in pediatric patients? Fever-induced convulsions are also hereditary, with about 10% of children with this condition having parents who had similar records when they were young. Many parents worry that these convulsions may turn into epilepsy, but in fact, unless there is a family history of epilepsy, the chance of developing epilepsy is not high. Fever-induced convulsions usually occur in children with fever due to upper respiratory tract infection or otitis media. The convulsions usually occur within the day the patient has a high fever (if they occur a few days after the fever or after the fever has subsided, there may be another cause). The patient loses consciousness and convulses the limbs or the whole body, and the condition is like grand mal epilepsy. However, if the convulsions are localized, it means that there is always a possibility of localized epilepsy or other diseases in the brain. In order to find out the cause of the disease, the doctor may take the child’s brain and spinal cord for testing. If a child has meningitis, early detection and treatment can also protect the child’s brain from damage. When a child has a seizure, many parents worry that a high fever will damage the child’s brain. However, fever damage to the brain is actually very rare. A fever of 103F or 104F is considered a high fever, but it is not enough to damage the brain; even if the temperature is as high as 105F, the chances are not great. In fact, it is the virus that invades the brain rather than high fever that poses a threat to the brain when a child is sick, so parents can rest assured.
