Febrile seizures (FS) occur in early childhood during a febrile illness. A typical or simple FS is characterized by a sudden loss of consciousness with either stiffening and myoclonic jerking or total loss of muscle tone. During a short initial tonic phase of the seizure, the child may stop breathing and tum blue. After a clonic phase of up to approximately 10 minutes of jerking or a phase of mere flacidness, the seizure stops and consciousness is recuperated. The child may then either fail into a deep sleep or be confused and disorientated for some time. Atypical or complex FS are either prolonged (i.e. duration longer than 30 minutes), focal, or occur multiple times within 24 hours. Usually, the febrile illness is one of the viral infectious diseases which are common in young infants. i ,2 Besides the fever) no other cause of the seizure can be found in the history, at physical examination, nor with additional laboratory investigations.
