• #1 Febrile Seizure Treatment, Definition, Symptoms & Causes

  https://www.medicinenet.com/febrile_seizures/article.htm

  Approximately one in every 25 children will have at least one febrile seizure, and more than one-third of these children will have additional febrile seizures before they outgrow the tendency to have them. Febrile seizures usually occur in children between the ages of 6 months and 5 years and are particularly common in toddlers. Children rarely develop their first febrile seizure before the age of 6 months or after 3 years of age. The older a child is when the first febrile seizure occurs, the less likely that child is to have more. […] During a febrile seizure, a child often loses consciousness and shakes, moving limbs on both sides of the body. Less commonly, the child becomes rigid or has twitches in only a portion of the body, such as an arm or a leg, or on the right or the left side only. Most febrile seizures last a minute or two, although some can be as brief as a few seconds while others last for more than 15 minutes.

• #2 Febrile seizure – Wikipedia

  https://en.wikipedia.org/wiki/Febrile_seizure

  Febrile seizures are triggered by fever, typically due to a viral infection. […] Signs of typical seizure activity include loss of consciousness, opened eyes which may be deviated or appear to be looking towards one direction, irregular breathing, increased secretions or foaming at the mouth, and the child may look pale or blue (cyanotic). […] Febrile seizures happen between the ages of 6 months and 5 years. […] The peak age for a febrile seizure is 18 months, with the most common age range being 12-30 months of age. […] Febrile seizures affect 2-5% of children. […] After a single febrile seizure there is an approximately 35% chance of having another one during childhood. […] Long term outcomes are generally good with little risk of neurological problems or epilepsy. […] Those who have one febrile seizure have an approximately 30-40% chance of having another one in the next two years, with the risk being greater in those who are younger. […] Simple febrile seizures do not tend to recur frequently (children tend to outgrow them) and do not make the development of adult epilepsy significantly more likely.

  https://www.merckmanuals.com/professional/pediatrics/neurologic-disorders-in-children/febrile-seizures

  Febrile seizures are diagnosed when seizures occur in children 6 months to 5 years of age who have fever (temperature 38 C) that is not caused by a central nervous system infection and who have had no previous afebrile seizures. […] Febrile seizures occur in approximately 2 to 5% of children 6 months to 5 years of age, and most occur between 12 months and 18 months of age. […] Often, febrile seizures occur during the initial rapid rise in body temperature, and most develop within 24 hours of fever onset. In general, higher temperature appears to be more important in influencing the onset of seizures compared to the relative rate of its increase. Typically, seizures are generalized; most are clonic, but some manifest as periods of atonic or tonic posturing. […] A postictal period of a few minutes is common but may last as long as a few hours. Drowsiness is common during this period; confusion and agitation are less common but are possible. If the postictal period is longer than an hour or if children have focal findings (eg, diminished movement on one side) during this period, they should be evaluated for an underlying acute central nervous system (CNS) disorder. Recovery to baseline neurologic status is generally rapid.

• #4 Febrile Seizures Following Childhood Vaccinations, Including Influenza Vaccination | Influenza (Flu) | CDC

  https://www.cdc.gov/flu/vaccine-safety/febrile.html

  The word febrile refers to having a fever. A seizure is a convulsion or uncontrolled body movements. A febrile seizure refers to a seizure/convulsion associated with a fever in a child. Febrile seizures usually last around one or two minutes and can occur with any condition that causes fever, such as a cold, influenza, or ear infection. They are most common with fevers of 102F (38.9C) or higher, but they can also happen at lower body temperatures or when a fever is going down. A person experiencing a febrile seizure may lose consciousness. […] Most febrile seizures happen in children between the ages of 6 and 59 months. Up to 5% of young children will have at least one febrile seizure. The most common age range for children to have febrile seizures is 14-18 months. […] Febrile seizures can be frightening, but nearly all children who have a febrile seizure recover quickly, are healthy afterwards, and do not have any permanent neurological damage. Febrile seizures do not make children more likely to develop epilepsy or any other seizure disorder. […] Vaccines can cause fevers, but febrile seizures are rare after vaccination. Importantly, getting sick with the flu also can cause febrile seizures. […] Flu illness can cause high fever and febrile seizures in children.

  https://www.emedicinehealth.com/seizures_and_fever/article_em.htm

  By definition, febrile seizures occur when the child has a fever. Most febrile seizures are generalized. In other words, the whole body may be involved. […] During a generalized seizure, any or all of the following may be seen: Stiffening of the entire body, Jerking of the arms and legs, Complete lack of response to any stimuli, Eyes deviated, staring, rolling back, moving back and forth, Tightness of the jaws and mouth, Urinary incontinence (wet their pants), Noisy breathing, labored, slower than normal (unusual for a child to stop breathing completely). […] Although it may seem like an eternity if you are witnessing a seizure, most of these episodes last only 1-5 minutes. Afterward, the child is typically drowsy but usually starts to become responsive within 15-30 minutes. […] Following a seizure, a child may remain somewhat twitchy, with intermittent small jerks of the arms or legs. It can be difficult to distinguish these movements from seizure activity, but the caregiver should be reassured if the child’s body tone has become relaxed, breathing is regular, and the child begins to show some signs of responding to stimulation (will respond if talked to, for example).

  Most febrile seizures cause convulsions or rhythmic twitching or movement in the face, arms, or legs that lasts less than one to two minutes. Less commonly, the convulsion lasts 15 minutes or more. […] Children who have a febrile seizure are at risk for having another febrile seizure; the recurrence rate is approximately 30 to 35 percent. Recurrent febrile seizures do not necessarily occur at the same temperature as the first episode, and do not occur every time the child has a fever. Most recurrences occur within one year of the initial seizure and almost all occur within two years.

  https://en.wikipedia.org/wiki/Febrile_seizure

  Febrile seizures are triggered by fever, typically due to a viral infection. […] Signs of typical seizure activity include loss of consciousness, opened eyes which may be deviated or appear to be looking towards one direction, irregular breathing, increased secretions or foaming at the mouth, and the child may look pale or blue (cyanotic). […] Febrile seizures happen between the ages of 6 months and 5 years. […] The peak age for a febrile seizure is 18 months, with the most common age range being 12-30 months of age. […] Febrile seizures affect 2-5% of children. […] After a single febrile seizure there is an approximately 35% chance of having another one during childhood. […] Long term outcomes are generally good with little risk of neurological problems or epilepsy. […] Those who have one febrile seizure have an approximately 30-40% chance of having another one in the next two years, with the risk being greater in those who are younger. […] Simple febrile seizures do not tend to recur frequently (children tend to outgrow them) and do not make the development of adult epilepsy significantly more likely.

  Most febrile seizures produce no lasting effects. Simple febrile seizures don’t cause brain damage, intellectual disability or learning disabilities, and they don’t mean your child has a more serious underlying disorder. […] Febrile seizures are provoked seizures and don’t indicate epilepsy. Epilepsy is a condition characterized by recurrent unprovoked seizures caused by abnormal electrical signals in the brain. […] 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-grade fever, The febrile seizure was the first sign of illness, An immediate family member has a history of febrile seizures, Your child was younger than 18 months at the time of the first febrile seizure.

  Febrile status epilepticus is continuous or intermittent seizures that last 30 minutes. When status epilepticus manifests as intermittent seizures, the seizures occur without neurologic recovery between seizures. Children with febrile status epilepticus are at risk of brain damage, particularly acute hippocampal injury that can progress to sclerosis, potentially resulting in the development of temporal lobe epilepsy. […] Overall recurrence rate of febrile seizures is approximately 20 to 35%. Risk of recurrence is higher if children are 1 year of age when the initial seizure occurs, with an increasing number of episodes of febrile seizures, or if children have first-degree relatives who have had febrile seizures. […] Risk of developing an afebrile seizure disorder after having 1 simple febrile seizure is approximately 2 to 6% slightly higher than the baseline risk of developing epilepsy (approximately 2% in children overall).

  A febrile seizure is a seizure caused by a fever in healthy infants and young children. Any fever may cause a febrile seizure. These seizures may happen when a child has an illness such as a cold, the flu, roseola, chickenpox, COVID-19, RSV (respiratory syncytial virus), or an ear infection. Most febrile seizures occur within 24 hours of a child getting sick. Sometimes, a child may have a seizure before developing a fever. […] Symptoms of febrile seizures may include: Loss of consciousness or passing out, Uncontrollable shaking, jerking, or stiffening in the arms or legs (may be the whole body or only part of the body), Eye rolling, Loss of bodily control (such as drooling, vomiting, urinating, or having a bowel movement).
