It has been estimated that one in every 100 children has epilepsy.
Epilepsy means that a child is susceptible to recurring seizures of various kinds.
In addition, any child may have a convulsive seizure due to high fever or other temporary condition. At some time, most teachers will have a seizure prone child in their classrooms, although neither they nor the child's parents may be aware of the fact until a seizure occurs. It isn't difficult to recognize a convulsive seizure. But non-convulsive ones are harder to spot. Untreated, they may interfere with learning.
