febrile seizure

a seizure arising from a high fever. It is the most common type of seizure in childhood and 20 to 30% of them recur. Febrile seizure is a benign condition for most children, but experiments with nonhuman animals and neuroimaging studies in humans suggest some febrile seizures may damage the hippocampus.
