Behavioral and Neurological Characteristics of a Hydranencephalic Infant

Abstract

A modified Prechtl neurological examination and the Brazelton Neonatal Assessment Scale were serially administered to a hydranencephalic infant over the first eight weeks of life. Clinical, roentgenographic, neurological and behavioral findings are reported. In contrast to earlier reports, visual tracking of a moving field and auditory and visual habituation were observed. Further, in addition to previously reported reflex automatisms, the infant also possessed what are termed "socially relevant behavioral automatisms". The implications of these findings are discussed.
