This unique book, the product of 20 years of clinical and electroencephalographic correlation, is an outgrowth of the author's vast experience. He has encountered the most intractable seizure problems especially in children who had not responded to anticonvulsants, and who were considered for selective neurosurgery in the neurosurgical service of Dr. A. Earl Walker.

Three hundred cases, all from the Johns Hopkins Hospital, are presented. They include 125 patients classified as the Lennox-Gastaut syndrome, 72 of common generalized epilepsy of the atypical type, 61 of the "pure" common generalized epilepsy, 26 with secondary bilateral synchrony, 7 with metabolic disturbances, 5 with deep-seated midline lesions, and 4 with posttraumatic epilepsy with slow spike-wave complexes.

Dr. Niedermeyer presents data from both standard and depth electroencephalographic studies as he investigates patients in each of the categories. These certainly warranted a more complex study than do those patients with focal seizures, where the clinical
