Febrile Seizures in Children: Symptoms, Causes, Diagnosis, Treatment, and Prevention

What Are Febrile Seizures?

Febrile seizures are sudden fits that happen in young children when they have a fever. Usually, these seizures occur in children between 6 months and 5 years old. Although febrile seizures can be scary, most are not harmful. In fact, many children outgrow them as they get older.

Common Symptoms of Febrile Seizures

Febrile seizure symptoms often appear quickly. For example, a child may suddenly lose consciousness or become stiff. Next, their arms and legs might shake or jerk. Sometimes, the eyes roll back. In most cases, the seizure lasts less than five minutes. Afterward, the child may feel sleepy or confused for a short time. However, not all children have the same symptoms. Here are the most common signs:

  • Sudden shaking or jerking of arms and legs
  • Loss of consciousness
  • Stiffness in the body
  • Eyes rolling back
  • Brief confusion or drowsiness after the seizure
  • Causes and Risk Factors

    Febrile seizures in children are usually triggered by a rapid rise in body temperature. Often, this happens during a viral or bacterial infection. For instance, ear infections, colds, or the flu can cause a fever that leads to a seizure. Although the exact cause is not always clear, several risk factors can increase the chance of febrile seizures:

  • Family history of febrile seizures
  • Age between 6 months and 5 years
  • High fever (usually above 100.4°F or 38°C)
  • Recent vaccination (rarely, as a fever may follow some vaccines)
  • However, febrile seizures are not caused by epilepsy. They also do not mean your child will develop epilepsy later.

    How Febrile Seizures Are Diagnosed

    Doctors diagnose febrile seizures by looking at the child’s medical history and symptoms. Usually, no special tests are needed if the child is healthy and the seizure was brief. However, if the seizure lasted longer than five minutes or the child has other health problems, the doctor may order tests. For example, blood tests, urine tests, or a spinal tap may help rule out other causes. Sometimes, an EEG (a test that checks brain activity) or a brain scan may be used if the doctor suspects another problem.

    Treatment Options for Febrile Seizures

    Most febrile seizures stop on their own within a few minutes. Therefore, treatment for febrile seizures often focuses on keeping the child safe during the episode. Here’s what you can do:

  • Lay your child on their side on a soft surface
  • Remove nearby objects to prevent injury
  • Do not put anything in their mouth
  • Stay calm and watch the seizure closely
  • After the seizure, let your child rest. If the seizure lasts longer than five minutes, call emergency services right away. In rare cases, a doctor may prescribe medicine to stop long seizures. However, daily medicine is not usually needed for most children.

    Prevention Tips and Home Care

    While you cannot always prevent febrile seizures, you can lower the risk by managing fevers early. For instance, use a digital thermometer to check your child’s temperature. If your child has a fever, try these steps:

  • Give fever-reducing medicine like acetaminophen or ibuprofen (as directed by your doctor)
  • Offer plenty of fluids to prevent dehydration
  • Dress your child in light clothing
  • Keep the room cool and comfortable
  • However, even with these steps, some children may still have febrile seizures. Therefore, it is important to stay prepared and know what to do if a seizure happens.

    When to Seek Medical Help

    Although most febrile seizures are not dangerous, you should seek medical help if:

  • The seizure lasts longer than five minutes
  • Your child has trouble breathing or turns blue
  • Your child does not wake up after the seizure
  • This is your child’s first seizure
  • The seizure happens without a fever
  • Your child has repeated seizures in a short time
  • In these cases, call your doctor or emergency services right away.
