Pattern reversal evoked potentials in infantile spasms. 1984

G Taddeucci, and A Fiorentini, and M Pirchio, and D Spinelli

Visual evoked potentials in response to sinusoidal gratings of various spatial frequencies, alternating in contrast at 8 Hz were recorded from infants affected by an idiopathic form of infantile spasms (West syndrome). In two infants in whom the spasms began at 3 and 5 months of age, respectively, the VEP's were found to be depressed in amplitude at and around a spatial frequency of 3 and 5 c/deg, respectively. This midfrequency depression, which has never been reported in the literature for normal infants, suggests that infantile spasms in idiopathic patients may interfere at least temporarily with the development of visual function.

D013036	Spasms, Infantile	An epileptic syndrome characterized by the triad of infantile spasms, hypsarrhythmia, and arrest of psychomotor development at seizure onset. The majority present between 3-12 months of age, with spasms consisting of combinations of brief flexor or extensor movements of the head, trunk, and limbs. The condition is divided into two forms: cryptogenic (idiopathic) and symptomatic (secondary to a known disease process such as intrauterine infections; nervous system abnormalities; BRAIN DISEASES, METABOLIC, INBORN; prematurity; perinatal asphyxia; TUBEROUS SCLEROSIS; etc.).
