Status epilepticus (SE) is a condition wherein epileptic seizure discharges are sufficiently prolonged or repetitive so as to produce persistent alterations in neurologic function and in the underlying physiologic and neurochemical activities of the brain. Thus, the definition of SE now includes any disorder in which there is sustained and prolonged excitation of neurons. Electroencephalographic (EEG) patterns associated with specific types of SE are important components in their classification. ⋯ Progressive behavioral and electrical changes have not been reported in primarily generalized forms of SE. EEG is an important tool for verifying successful treatment of SE if the patient does not immediately recover neurologic function. EEG recordings also contribute substantially to understanding the mechanisms of, and development of better treatments for, human SE through their use in the study of experimental SE in the laboratory.
