The long-term significance of neurological findings at toddler's age.

Eighty neurologically abnormal infants were re-examined neurologically at 1 1/2, 4 and 9 years of age. Eighty normal newborn were seen again at 1 1/2 and 4 years. Special attention was paid to the presence of minor neurological dysfunction (MND). Changes in neurological classification occurring during the period of time in question are discussed. Neurological handicap could be spotted reliably at 18 months. The frequency of MND increases with age, however.
