Electroencephalographic lateralization in chronic infantile hemiplegia

Abstract In 20 of 40 patients with chronic infantile hemiplegia, EEGs failed to lateralize cerebral dysfunction as determined clinically. Patients with “concordant” clinical EEG lateralization were compared to those with “discordant” or non-localizing findings. There was no difference between these groups as to sex, age, cerebral vascular resistance and cerebral oxygen consumption. However, cerebral blood flow was significantly lower in the group with discordant lateralization suggesting the existence of generalized bilateral brain damage.
