[Relationship between electroencephalographic abnormality and late blink reflex responses in infantile spasms and EIEE].
Electrically elicited blink reflex (BR) were analyzed in seven patients with age dependent epileptic encephalopathies (5 patients with infantile spasms and 2 with EIEE). Four patients with infantile spasms showed prolonged latency of the late BR responses (R2). In 2 patients with EIEE showing suppression burst pattern on EEG, R2 was not detectable. R2 abnormality in BR might reflect the dysfunction of the brainstem reticular formation in age dependent epileptic encephalopathies.
