A febrile seizure, also referred to as febrile convulsion or fever fit, is a seizure that is normally characterized by high body temperature but usually without a serious underlying health concern.
These seizures are common in children between the ages of six months and five years, and most of them are usually, less than five minutes in duration and once they are over, the child normally feels well within 60 minutes of the event.
Febrile seizures are classified into three broad categories:
Simple febrile seizures
These febrile seizures are characterized by relatively shorter duration, usually less than 15 minutes. In addition, the shaking is often more generalized as opposed to occurring in a specific area of the body. These seizures also do not usually recur, and children are known to grow out of them.
Complex febrile seizures
These refer to the febrile seizures that usually last more than 15 minutes or may happen in episodes that occur within 24 hours. Like the simple febrile seizures, they also have to focal features.
Febrile status epilepticus
These seizures normally occur for longer than 30 minutes. They account for up to 5% of all known seizure cases. This type of febrile seizures are very dangerous, so visiting a doctor is a must.
The major cause of febrile seizures is fevers, especially those fevers that are higher 100.4°F (38°C). The fever itself is often due to viral infections.
In addition to fevers, these seizures may also be caused by the mineral deficiency, especially iron deficiency. The possible cause of febrile seizures is heredity, where certain cases have been associated with genetic predisposition. However, that happens really rarely.
Signs and symptoms
Apart from high temperatures, febrile seizures are usually followed by a long period of sleep. But it is not the only symptom. The following are the signs and symptoms of these seizures:
- Body stiffness
- Twitching in the arms and legs
- Loss of consciousness even though the eyes may remain open
- Irregular breathing patterns
- Vomiting and increased secretions as manifested by foam in the mouth
- Bowel and bladder incontinence resulting in the child wetting and soiling themselves
Diagnosis and treatment
The diagnosis of febrile seizures is needed to reduce the risk of severer causes of fever. These causes often include but not limited to encephalitis and meningitis. There is no prescribed test for febrile seizures, and the tests conducted are usually for the other causes of fever.
But you should never ignore the early signs. Remember, it is your child’s health. Children with prolonged seizures often require a degree of personalized treatment, so make sure you do see your child’s doctor as soon as your little one starts feeling bad.
