Children are asked to have an EEG for many reasons, and some may be found to have EEG epileptiform discharges. In healthy children without epilepsy, 1.9% to 3.5% had epileptiform discharges on the EEG, with central-middle temporal discharges and generalized spike-slow wave discharges accounting for the majority of these discharges.Cavazutti et al. performed EEG examinations on 3726 neurologically normal children aged 6-13 years without a history of epilepsy. They found that 2.3% of the children had Rolandic or parietal or mesial-temporal epilepsy discharges. In a series of 386 children who were neurologically normal but had central discharges on EEG with normal background activity, Kellaway found that only 57% had epileptic seizures. In another series of 315 patients with central temporal lobe discharges, Beaussart found that 16% did not have epilepsy. A child found to have epileptiform discharges on EEG does not necessarily have epilepsy, but is just more likely to have seizures than a child with a normal EEG, so long-term observation is needed, with reference to the clinical presentation of benign epilepsy with central temporal spike waves (BECT) in children. BECT clinical seizure features: they are restricted seizures, some of which can be followed by generalization, and seizures during sleep are more likely to generalize. The seizure symptoms are highly variable and may vary from one child to another and from one child to another. 70%-80% of the seizures occur during sleep, and even daytime seizures are mostly associated with sleepiness, while a few patients have seizures both during wakefulness and sleep, and only 10%-20% of children have seizures only during wakefulness. Sensory and motor seizures of the face and mouth are most common. The duration of seizures varies from a few minutes to ten minutes and rarely appear to be continuous. A typical seizure occurs shortly after falling asleep or early in the morning when the child is awake and is conscious but unable to speak, understand language or communicate through gestures, with the corners of the mouth tilted to one side, with twitching of the side, grunting and salivation in the throat. The seizure may involve the ipsilateral upper limb, or start with a twitch of one hand and upper limb, or occasionally the lower limb, with clonic jerking, tonic contraction or abnormal sensation. The seizure may be accompanied by Todd’s palsy. There is no confusion at the end of the seizure. The child may complain of a numbness, tingling or electric shock sensation and lip and tongue stiffness on one side of the tongue, dental bed and cheek at the beginning of the seizure. A partial seizure may develop into a disorder of consciousness or rapidly spread into a generalized seizure. The child may not be able to recall the course of the seizure and may be easily mistaken for a primary generalized seizure if symptoms of a partial sensorimotor seizure are not available at this time. Daytime seizures are briefer than nighttime seizures, and sometimes they only show sensory symptoms on the face, oropharynx, or one limb, which may be overlooked if the child is confused. The frequency of seizures varies greatly between individuals. 10%-13% of children have only one seizure in their lifetime, which does not recur even without treatment. 66% of patients have sporadic seizures with an interval of 2-12 months between seizures. However, 20% of children have more frequent seizures, almost every night or several times a night. Seizures often tend to occur in clusters and can be frequent for several weeks and then not occur for a long time. A small number of children have prolonged salivation and slurred speech after seizures, and may also have a persistent state of convulsions.
