Final answer:
Febrile seizures cannot be diagnosed in a child with a history of epilepsy.
Step-by-step explanation:
Febrile seizures are seizures that occur during a febrile illness, such as a high fever. These seizures are most common in children between the ages of six months and five years. To diagnose febrile seizures, the child cannot have a history of epilepsy. Epilepsy is a chronic disorder characterized by recurrent seizures that can occur without a fever. While febrile seizures are usually harmless and do not require treatment, epilepsy requires ongoing management and may require medication or even surgery.
