Causes, incidence, and risk factors
About 3 – 5% of otherwise healthy children between ages 9 months and 5 years will have a seizure caused by a fever. Toddlers are most commonly affected. Febrile seizures often run in families.
A febrile seizure may be as mild as the child’s eyes rolling or limbs stiffening. Often a fever triggers a full-blown convulsion that involves the whole body.
Signs and tests
The health care provider may diagnose febrile seizure if the child has a grand mal seizure but does not have a history of seizure disorders (). In infants and young children, it is important to rule out other causes of a first-time seizure, especially meningitis.
During the seizure, leave your child on the floor.
The first febrile seizure is a frightening moment for parents. Most parents are afraid that their child will die or have brain damage. However, simple febrile seizures are harmless. There is no evidence that they cause death, brain damage, epilepsy, mental retardation, a decrease in IQ, or learning difficulties.
