AB Tonic  seizures  have  long  been  recognized  as  a  seizure  type  that  often  occurs  in  the  setting  of  symptomatic  generalized  epilepsy,  more  specifically,  as  part  of  the  Lennox-Gastaut  syndrome.  Although  this  may  be  the  most  common  clinical  scenario  where  tonic  seizures  are  seen,  they  occur  in  other  epilepsy  syndromes  and  can  also  be  a  manifestation  of  focal  epilepsy  with  secondary  generalization.  The  prominent  bilateral  involvement  of  muscle  groups  led  to  classifying  tonic  seizures  as  a  “generalized”  seizure  type,  and  though  true  in  many  patients,  a  variety  of  electroencephalographic  (EEG)  patterns  and  clinical  phenomena  have  been  described.  This  chapter  will  address  tonic  seizures  across  the  age  spectrum,  with  particular  attention  paid  to  specific  clinical  and  neurophysiologic  correlates.
