Seizures in infants are not necessarily serious, but these kinds of events in children should be considered abnormal and must be examined. Seizures may occur during a fever: these are hyperthermic seizures. While frightening, they are not serious and are not responsible for any repercussions. This usually appears as involuntary contractions of the muscles of the baby, with a loss of contact during the attack that lasts a few seconds. A loss of consciousness at the end of the convulsion is possible. It is important to differentiate between a hyperthermic seizure and a pathological seizure, in which epilepsy may be suspected. Depending on the context, an electroencephalogram, which records the electrical activity of the brain of the child, can be practiced.
