Seizures in children indicate epilepsy, according to WebMD. Doctors check for changes in blood sugar, blood pressure and stress levels before rendering an epilepsy diagnosis for children.
Wikipedia notes that most children who suffer from epilepsy are not epileptic when reaching adulthood, and children may also experience a single epileptic seizure and never suffer from it again. However, epileptic seizures in children interrupts their education, and it can affect their memorization skills. Tonic-clonic seizures can cripple a child's education because time is needed to recover from memory loss. Absence seizures are not as harmful as tonic-clonic seizures, but they are frequent episodes that occur throughout the day.
eMedicineHealth notes that children who suffer from absence seizures experience a loss of consciousness as they are blinking or staring, but they revert to a normal state when the episode is over. Febrile seizures include muscle spasms and jerking, and the child usually does not remember the seizure. Smacking the lips, clapping and chewing are associated with complex partial seizures, and partial seizures may only affect a single muscle group.
Wikipedia further notes that the causes of epileptic seizures in children include congenital defects, traumatic episodes, stroke, tumors, injections and degenerative effects. Congenital defects are primary causes of epileptic seizures in children, but the root of the problem remains unknown in most cases.
