Mesencephalic Structures and Tonic—Clonic Generalized Seizures

  • Chapter
Generalized Epilepsy

Abstract

A role for the brain stem in the initiation of convulsive disorders has been suspected for a long time. Clinical observations made evident that tonic-clonic generalized seizures (TCGS) resembled the picture induced by lesions in the upper brain stem (Van der Kolk, quoted by Muskins, 1928) and experiments performed in the past century revealed that mechanical or electrical stimulation of the brain stem produced convulsions (for a historical review, see Temkin, 1971, and Fromm, 1987). After the experiments of Fritsch and Hitzig (1870) that produced generalized seizures by electrical stimulation of the cerebral cortex in dogs, the cerebral cortex was taken as the place of origin of the epileptic attacks. For the past hundred years, evidence of cortical versus subcortical initiation of convulsive seizures has been presented, and although there has been more clinical and experimental evidence that favors a cortical origin for the majority of the epilepsies, a renewed interest in the possible brainstem origin of some types of epilepsy, particularly the TCGS, has arisen from numerous recent experimental observations.
