Summary Summary

Febrile infection-related epilepsy syndrome (FIRES) is a severe brain disorder that develops in previously healthy children after a fever. This syndrome causes a very sudden (acute) onset of nearly continuous seizures (status epilepticus) which do not respond to seizure medications (medications to stop seizures). When seizures cannot be controlled by medication, they are called refractory seizures or refractory epilepsy. Sadly many children with FIRES do not live past the acute phase.^[1]^[2]^[3]

The acute phase of FIRES is followed by a chronic phase in which the number of seizures decreases, developing into chronic, refractory focal epilepsy. The seizures continue to be hard to control with medications. During the chronic phase, memory and intellectual ability often decline. FIRES can also cause psychiatric disorders or problems with motor skills. The cause of FIRES is unknown, but may be related to infection, genetic susceptibility, an autoimmune disorder, or a problem with metabolism. FIRES affects children between the ages of 3-15 years old. Although seizure medications are not able to completely control the epilepsy, some children do respond to a ketogenic diet, especially if begun early after the initial acute phase. Therapies such as behavioral, physical and occupational therapy as well as other treatments may be recommended depending on the symptoms which develop during the chronic phase.^[1]^[2]^[3] There have been rare cases of FIRES in which the children have fully recovered.^[1]^[4]

Symptoms Symptoms

This table lists symptoms that people with this disease may have. For most diseases, symptoms will vary from person to person. People with the same disease may not have all the symptoms listed. This information comes from a database called the Human Phenotype Ontology (HPO) . The HPO collects information on symptoms that have been described in medical resources. The HPO is updated regularly. Use the HPO ID to access more in-depth information about a symptom.
