Y1 - 2011 N1 - T2 - Atlas of Video-EEG Monitoring 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.
