The value of performing a careful neonatal neurologic examination frequently is questioned on the basis of two major contentions. The first is that the usual examination evaluates only function of subcortical structures, and the second, related in large part to the first, is that abnormal neurologic findings are poor indicators of subsequent neurologic abnormality. We consider neither of these contentions to be supported by available data and discuss each briefly below.
The usual support raised for the contention that the neonatal neurologic examination evaluates only function of subcortical structures relates to findings with hydranencephalic and anencephalic infants. Such infants often exhibit sleep-wake cycles, blink to light and sound, normal pupillary responses, and reflex extraocular movements.1,2
