What is Febrile infection-related epilepsy syndrome - FIRES

Febrile infection-related epilepsy syndrome (FIRES) is a rare and catastrophic form of new-onset refractory status epilepticus that typically begins in previously healthy children following a mild febrile illness. It is characterized by the sudden onset of frequent, hard-to-control seizures that often lead to long-term cognitive and neurological challenges.

What exactly is Febrile infection-related epilepsy syndrome (FIRES)?

Febrile infection-related epilepsy syndrome (FIRES) is a subcategory of New-Onset Refractory Status Epilepticus (NORSE). While the exact cause remains unknown, the medical community currently views Febrile infection-related epilepsy syndrome (FIRES) as an immune-mediated condition where the body’s inflammatory response to a common infection triggers uncontrolled brain electrical activity. Currently, 65 members of the DiseaseMaps.org community are navigating the complexities of Febrile infection-related epilepsy syndrome (FIRES), highlighting the need for specialized care and global collaboration.

Who is most affected by FIRES?

Febrile infection-related epilepsy syndrome (FIRES) typically affects children between the ages of 3 and 15 years. Before the onset of symptoms, these children are generally healthy with no prior history of epilepsy or neurological issues. There is no known geographic or ethnic bias, and data on gender distribution remains inconsistent, though some studies suggest a slight male predominance.

What are the clinical phases of FIRES?

The progression of Febrile infection-related epilepsy syndrome (FIRES) generally follows a distinct clinical course:

• Febrile onset: A minor illness with fever occurs 1 to 14 days before the onset of seizures.


• Acute phase: Intense, frequent seizures begin, often becoming resistant to standard anti-seizure medications. This phase can last from weeks to months.


• Chronic phase: Following the acute phase, patients often develop chronic epilepsy and varying degrees of cognitive, motor, or behavioral impairment.
