Abstract: Ictal electroencephalographic/video recordings of 42 patients with West syndrome (WS) were reviewed to define the relation between ictal, clinical, and EEG features and etiology or prognosis. The duration and type of spasms, the number of spasms per cluster, and the interval between spasms did not correlate with the etiology or the short-term prognosis, However, eye deviation, asymmetric spasms, and partial seizures concomitant with spasms were observed only in symptomatic WS patients with poor outcome, In particular, all 8 patients with concurrent partial seizures had severe psychomotor retardation, The ictal EEG characteristics did not correlate with etiology and prognosis, There was no significant difference between the patients with persistence or reappearance of hypsarrhythmia and the patients without interspasm hypsarrhythmia.
