Febrile seizures are a common cause of convulsions in young children. They occur in 2 to 4 percent of children younger than five years of age, but the incidence is as high as 15 percent in some populations. This incidence has been attributed to closer living arrangements among family members making detection more likely, but racial and geographic variations may also be important.
The generally accepted criteria for febrile seizures include:
●A convulsion associated with an elevated temperature greater than 38°C
●A child younger than six years of age
●No central nervous system infection or inflammation
