The blink reflex and its recovery curve were studied in 12 patients with neurologic and psychiatric disorders, i.e., juvenile Parkinson's disease (case 1), Gilles de la Tourette's syndrome (case 2), anorexia nervosa (case 3), mild developmental delay (cases 4 and 5), a meningomyelocele with winking spasms (case 6), Parkinson's disease (cases 7-10) and OPCA(More)
Electrophysiological studies of a child with presumed botulism showed that the amplitude of the serially and electrically elicited blink reflexes Rl, R2 and R2' was reduced during recovery. These findings suggest a conduction block of the facial nerves. Other nerve conduction studies and an incremental response to repetitive stimulation demonstrated a block(More)
We examined maturational changes in the electrical blink reflex in 11 handicapped children, i.e., 4 cases of developmental delay, 4 of cerebral palsy, 2 of congenital hydrocephalus, and 1 of congenital cytomegalovirus infection. The developmental delay and cerebral palsy cases were all born at 25-36 weeks' gestation. In all cases, prolonged latency, low(More)
The electrophysiologic findings in an infant with congenital facial diplegia (Möbius syndrome) are presented. As to serial electrically elicited blink reflexes, the R1 amplitude was significantly reduced and the R2 latency was significantly prolonged. The M response of the orbicularis oculi muscle showed slightly reduced amplitude. Auditory brainstem(More)
