Summary Five patients with the Lennox‐Gastaut syndrome who have shown generalized non‐convulsive seizures were presented. The seizure manifestations which occurred spontaneously were documented by simultaneous recording and analyzed in terms of clinical and electroencephalographic correlates. According to the diagnostic criteria of the International Classification, 2 it was possible, on the one hand, to regard them as “atypical complex absences” in which the impairment of consciousness is accompanied by other symptoms, which tend to dominate the clinical picture. They were: hypotonic, hepertonic, myoclonic and akinetic components, respectively. On the other hand, if we give a special weight to the accompanying symptoms, it is entirely possible that they are at the same time diagnosed atonic, axial tonic, bilateral myoclonic and akinetic seizures. The initial impairment of consciousness is common to all the seizure manifestations, and the ictal and interictal EEG expressions are not of diagnostic significance. A question arises as to whether two different nomenclatures were arbitrarily given to a unique ictal manifestation or not as far as the generalized non‐convulsive seizures were concerned.
