WebA classic example of polymorphic slowing is seen with slow wave sleep, in which high amplitude polymorphic delta activity predominates the recording. Polymorphic slowing can also be abnormal, though, as is the case with focal polymorphic slowing caused by tumors or bleeds (slowing is discussed in the nonepileptiform abnormalities section).
