DEFINICION
A febrile seizure is a convulsion in young children that may be caused by a spike in body temperature, often from an infection. Watching your child experience a febrile seizure can be alarming. And, although a febrile seizure may last only afew minutes, it may seem like an eternity to you.

Febrile seizures represent a unique response of a young child's brain to fever. Fortunately, febrile seizures aren't as dangerous as they may look. They're usually harmless and typically don't indicate a long-term or ongoing problem. You can help your child by keeping him or her safe during a febrile seizure and offering comfort afterward.After a febrile seizure, call your doctor to have your child evaluated as soon as possible.
SINTOMAS
Febrile seizure symptoms can range from mild — rolling of the eyes — 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 the arms and legs on both sides of the body
Rollhis or her eyes back in the head
Febrile seizures are classified as simple or complex:

Simple febrile seizures. These are the most common type of febrile seizure, and they can last from a few seconds to 15 minutes. Simple febrile seizures do not recur within a 24-hour period. These seizures begin as a generalized tonic-clonic (grand mal) seizure and don't involve staring or shaking of just onepart of the body.Complex febrile seizures. A complex febrile seizure 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 as the body temperature quickly rises, usually within 24 hours of the onset of a fever, and can be the first sign that a child is ill.

When to see doctor
See your child'sdoctor as soon as possible if your child has his or her first-time febrile seizure, even if it lasts only a few seconds. If the seizure ends quickly, call your doctor as soon as it's over and ask when and where your child can be examined.

Call for an ambulance to take your child to the emergency room if the seizure lasts longer than 10 minutes or is accompanied by:

Vomiting
A stiff neckProblems with breathing
Extreme sleepiness
CAUSAS
Most febrile seizures occur because of a sudden spike in body temperature, and most occur during the first day of a fever.

Viral or bacterial infection
Usually, the fevers that trigger febrile seizures are caused by a bacterial or viral infection in your child's body. Typical childhood illnesses, including respiratory illnesses and infectionssuch as roseola — a viral illness that causes swollen lymph nodes, usually in the neck, and a rash — are often associated with febrile seizures. A less common but very serious cause of sudden fever with seizures is an infection of a child's brain and spinal cord (central nervous system), such as meningitis or encephalitis. These illnesses may also cause seizures without a fever.Post-immunization seizures
The risk of febrile seizures may increase after some childhood immunizations, such as the diphtheria, tetanus and pertussis (DTP) or measles-mumps-rubella (MMR) vaccinations. Low-grade fevers can sometimes occur after your child receives childhood vaccines. If a febrile seizure occurs, it's caused by the fever that may accompany the vaccination — not by the vaccination itself.FACTORES DE RIESGO
Several risk factors have been identified that increase your child's likelihood of experiencing a febrile seizure. These include:

Young age. Young age is the strongest risk factor, and most febrile seizures are seen in children who are between 6 months and 5 years of age. It's unusual for children under 6 months old to have a febrile seizure, and it's rare for these seizures to...
