Febrile seizure

Fact Checked

A febrile seizure is defined as a convulsion brought about by erratic electrical activity in the nerve cells of the brain that is triggered by fever. The precise cause is still unknown. An episode might arise if the temperature of the child increases or drops rapidly. Generally, a seizure could not be predicted or prevented.

A febrile seizure typically affects children between 6 months up to 5 years old. In most cases, it lasts for 3-5 minutes.

The seizure might only affect an arm or one side of the body which is localized and later progresses to the entire body which becomes generalized. It can also affect both sides of the body at the start.
