What is a seizure?
John Hughlings Jackson (North Yorkshire 1835 – London 1911)
Studying his wife (who had ‘Jacksonian’ seizures), he stated:
“I have for more than ten years, and before the experiments of Hitzig and Ferrier were made, held that convolutions of the brain contain nervous arrangements representing movements. It is in accordance with this belief that I have long considered chorea, and more lately convulsion, to be movements resulting from 'discharges' of the cerebral cortex.” This results in “an occasional, an excessive and a disorderly discharge of nerve tissue of muscle.”
What is epilepsy?

-By recurrent epileptic seizures1 or by an enduring predisposition to generate epileptic seizures2
