What causes a febrile seizure?

The rise of fever. Febrile seizures are common in children, about 5% of the population. They are generally a combination of how fast the fever rises and a genetic predisposition. Very few children with febrile seizures go on to have epilepsy, but that is still being studied.
New research. New research is looking into the biological basis for febrile seizures. They occur in children from 4 months to about 6 years in 3 patterns. 1 -seizure and then parents become aware the child is ill 2. During a rapid rise in body temperature and 3. After the fever has been established for hours or a day. the seizures are generalized and usually brief. If brief, they do not cause damage.

What can cause febrile seizures besides having a fever?

Temperature change. Febrile seizures are believed to be precipitated by rapid changes in body temperature that occur when the fever is developing, or when temperatures abruptly drop (this is why we don't recommend very cold baths or alcohol rubs for fevers). That being said, a child with tendencies to febrile seizures can have an episode before the fever has fully developed. Read more...

My question is what causes febrile seizures besides having a fever?

By definition. Seizures in young children associated with high fevers are termed "febrile seizures". The prognosis for the future is usually very positive.

Can anyone tell me what causes febrile seizures besides having a fever?

Simple or complex ? Simple febrile seizures can run in families. With complex febrile seizures one sees focal neurological deficits after the seizure or the seizures are prolonged or occur in clusters. It is more likely that there is some underlying pathology with the latter ( developmental disorder, vascular malformation, etc) the eeg is likely to be abnormal between seizures. Read more...

By definition-no. The problem in infancy is separating out the ones that have a seizure disorder that became evident during an event, or an event that was a simple febrile seizure. Febrile seizures by definition are relatively brief, come on in a defined fashion, and do not involve any interference with providing oxygen to the brain. If they have a bad seizure & get brain damage, it is a seizure disorder. Read more...

Can febrile seizures cause permanent brain damage in a person?

Definition issue. By definition, febrile seizures are considered benign, lasting only minutes & not leading to respiratory compromise. As long as the brain & heart get oxygen, the chances of death or disability is remote & kids outgrow them. However, some kids with epilepsy will have a seizure with a fever, & carry a fsz label but go on to have major seizures with damage as they get older. Read more...

If you had febrile seizures when you were young, could it caused brain damage?

Not by definition. Febrile seizures are common:1/20 kids 6m-6yr. By definition the term is applied to seizures not thought to be triggered by or cause brain injury.Whether brief or longer, the label was seldom used if the kids seizure resulted in impairment of oxygen flow to the brain which would be the main cause of injury.The seizure itself did not.Problems come if true epilepsy emerges in young kids & confuses us.
