Febrile infection-related epilepsy syndrome (FIRES) is a form of epilepsy that affects children three to fifteen years old. A healthy child that may have been ill in the last few days or with a lingering fever goes into a state of continuous seizures. The seizures are resistant to seizure medications and treatments, though barbiturates may be administered. Medical diagnostic tests may initially return no clear diagnosis and may not detect any obvious swelling on the brain. The syndrome is very rare: it may only affect 1 in 1,000,000 children.

Signs and symptoms
FIRES seizures are non-focal - there is no specified starting or stopping point - making brain surgery impossible. These seizures damage cognitive abilities of the brain such as memory or sensory abilities. This can result in learning disabilities, behavioral disorders, memory issues, sensory changes, inability to move, and death. Children continue to have seizures throughout their lives.
Cause
The cause of FIRES is not known. It does not happen twice in the same family, but the medical community does not know if it is genetic. It happens in boys more than girls. After the initial status, life expectancy is not affected directly. Issues such as overdose of medications or infections at a food tube site are examples of things that would be secondary to the status.
Treatment
History
FIRES was named in 2008 by Dr. Andreas van Baalen and colleagues. Previous names include AERRPS, DESC (Devastating Epileptic encephalopathy in School-aged Children), and NORSE (New-Onset Refractory Status Epilepticus).
