Epilepsy is a chronic disease triggered by increased impulsiveness of nerve cells in the brain and may require a lifelong treatment. Epilepsy is confirmed by two or more unprovoked seizures in more than 24 hours. Febrile Convulsion is another type of seizure occurring due to fever over 38 °C without a history of convulsion, CNS infection, electrolyte imbalance, metabolic disorder, intoxication, and trauma. Unlike epileptic seizures, there are non-epileptic seizures such as Breath Holding Spells that affect children's behaviors and often look like epileptic seizures.
