Summary Patients with spike and wave, classified as to the origin and frequency, were studied and the following conclusions were arrived at: (1) Spike and wave is closely related to child epilepsy; concerning its clinical seizure types, the minor seizure was perceivable in most cases, followed, in order, by the major seizure and the psychomotor seizure. (2) As to the complication of mental defects, items of the presumable cause (in the form of brain damage), the behavior disorder and the neurological symptoms all seemed much more intensive in the slow group than in the fast group. (3) As to the relation between discharges of spike and wave and frequency of clinical seizure, drugs with a diminishing effect on the frequency of seizures seemed to have the same effect on spike and wave in the EEG. (4) It can be presumed from the clinical, biochemical and experimental‐physiological observations that, though spike and wave is closely related to immaturity of the brain. the difference of its frequencies between the fast and the slow groups might well indicate not only a temporal differences in developmental grades of immature brains, but also the characters of their heterogenous functional scope.
