Anfallen advances are uncomfortable to watch but short individual


Kramp They occur usually in 1-2 years of age and almost never after 4 years of age. Fever Convulsions occur in ca. 2% of all children. The reason that the fever in precisely these children may develop convulsions, are not known in detail, but there is some hereditary link. Thus, a child is a greater risk of developing febrile convulsions than other children if their parents also had febrile convulsions. Many experience only one


Symptoms of febrile convulsions

The typical febrile seizures is a so-calledgenraliseret tonisk-klonisk attackorgrand mal:

If your child has had fever cramps and now has a fever, you should take the temperature every two hours. A body temperature over 38 degrees can cause convulsions, and it is therefore important that the temperature is kept down by stripping the child and such. use a sheet instead of the duvet.

The typical febrile seizures are not harmful to the child, but prolonged or repeated seizures shortly after each other can potentially be hazardous due to lack of oxygen supply to the brain for longer periods. Such a lack of oxygen can cause damage to brain tissue, but there is rarely a serious functional damage.

Children with complex (long) or numerous seizures of epilepsy should be paid. It is however very small percentage who develop genuine epilepsy with convulsions after childhood.
