Febrile seizures are convulsions that can happen during a fever (febrile means "feverish"). They affect kids 3 months to 6 years old, and are most common in toddlers 12-18 months old.
There are two types of febrile seizures Simple febrile seizures are usually over in a few minutes, but in rare cases they can last up to 15 minutes. During this type of seizure, a child's whole body may convulse, shake, and twitch; his or her eyes may roll; and he or she may moan or become unconscious. Children can sometimes vomit or urinate (pee) on themselves during the convulsions.
Treatment: A child who has a febrile seizure should be seen by a healthcare provider as soon as possible (in an emergency department or provider's office) to determine the cause of the fever.
