Types, causes, Treatment of febrile seizures

DEFINITION

A febrile seizure is a convulsion in a child that may be caused by a spike in body temperature, often from an infection. Your child’s having a febrile seizure can be alarming, and the few minutes it lasts can seem like an eternity.

Febrile seizures represent a unique response of a child’s brain to Fever, usually the first day of a Fever. Fortunately, they’re usually harmless and typically don’t indicate an ongoing problem. You can help by keeping your child safe during a febrile seizure and by comforting him or her afterward.

Call your doctor to have your child evaluated as soon as possible after a febrile seizure.

SYMPTOMS

Febrile seizure symptoms can range from mild — staring — to more severe shaking or tightening of the muscles.

A child having a febrile seizure may:

  • Have a Fever higher than 100.4 F (38.0 C)
  • Lose consciousness
  • Shake or jerk arms and legs
  • Febrile seizures are classified as simple or complex:

  • Simple febrile seizures.

     This more common type lasts from a few seconds to 15 minutes. Simple febrile seizures do not recur within a 24-hour period and are generalized, not specific to one part of the body.

  • Complex febrile seizures. 

    This type lasts longer than 15 minutes, occurs more than once within 24 hours or is confined to one side of your child’s body.

  • Febrile seizures most often occur within 24 hours of the onset of a Fever and can be the first sign that a child is ill.

    CAUSES

  • A high body temperature causes most febrile seizures.
  • Infection
  • Usually the Fevers that trigger febrile seizures are caused by a viral infection, less commonly by a bacterial infection. Viral infections such as the Flu and Roseola, which often are accompanied by high Fever, appear to be most associated with febrile seizure.
  • Post-immunization seizures
  • The risk of febrile seizures may increase after some childhood immunizations, such as the Diphtheria, Tetanus and pertussis or Measles-Mumps-Rubella vaccinations. A child can develop a low-grade Fever after a vaccination. The Fever, not the vaccination, causes the seizure.
  • RISK FACTORS

    Factors that increase the risk of having a febrile seizure include:

  • Young age.

     Most febrile seizures occur in children between 6 months and 5 years of age. It’s unusual for children younger than 6 months to have a febrile seizure, and it’s rare for these seizures to occur after 3 years of age.

  • Family history.

     Some children inherit a family’s tendency to have seizures with a Fever. Additionally, researchers have linked several genes to a susceptibility to febrile seizures.

  • COMPLICATIONS

  • Most febrile seizures produce no lasting effects. Simple febrile seizures don’t cause brain damage, mental retardation or learning disabilities, and they don’t mean your child has a more serious underlying disorder.
  • Febrile seizures don’t indicate epilepsy, a tendency to have recurrent seizures caused by abnormal electrical signals in the brain.
  • Recurrent febrile seizures
  • The most common complication is the possibility of more febrile seizures. The risk of recurrence is higher if:

  • Your child’s first seizure resulted from a low Fever.
  • The period between the start of the Fever and the seizure was short.
  • An immediate family member has a history of febrile seizures.
  • Your child was younger than 15 months at the time of the first febrile seizure.
  • TREATMENTS AND DRUGS

  • Most febrile seizures stop on their own within a couple of minutes. If your child has a febrile seizure that lasts more than 10 minutes — or if your child has repeated seizures — call for emergency medical attention.
  • More-serious episodes
  • If the seizure lasts longer than 15 minutes, a doctor may order medication to stop the seizure.
  • If the seizure is prolonged or accompanied by a serious infection or if the source of the infection can’t be determined, then your doctor may want your child to stay in the hospital for further observation. But a hospital stay isn’t usually necessary for simple febrile seizures.
  • LIFESTYLE AND HOME REMEDIES

    Most febrile seizures occur in the first few hours of a Fever, during the initial rise in body temperature.

    Giving your child medications

    Giving your child infants’ or children’s acetaminophen (Tylenol, others) or ibuprofen (Advil, Motrin, others) at the beginning of Fever may make your child more comfortable, but it won’t prevent a seizure.

    Use caution when giving aspirin to children or teenagers. Though aspirin is approved for use in children older than age 3, children and teenagers recovering from Chickenpox or Flu-like symptoms should never take aspirin. This is because aspirin has been linked to Reye’s syndrome, a rare but potentially life-threatening condition, in such children.

    Prescription prevention medications

    Rarely, prescription anticonvulsant medications are used to try to prevent febrile seizures. However, these medications can have serious side effects that may outweigh any possible benefit.

    Oral diazepam (Valium), lorazepam intensol, clonazepam (Klonopin) or rectal diazepam (Diastat) may be prescribed for children who are prone to febrile seizures. These medications are typically used to treat seizures that last longer than 10 minutes or if the child has more than one seizure within 24 hours. They are not typically used to prevent febrile seizures.
