Neurologic outcomes of infants with tremor within the first year of life.
The neurologic outcomes of 24 infants with no other overt neurologic signs except for tremor that lasted through or began after the neonatal period were evaluated during a follow-up period of 3-10.2 years (mean = 6.8 years). Twenty patients had normal outcomes, three had borderline intelligence, and the remaining patient had cerebral palsy (to a minimum degree). The duration, incidence, persistence, and type of tremor were not related to the neurologic outcomes in this group. The outcomes of the 10 children with no perinatal complications were good. In contrast, among the 14 children with perinatal complications, four had mild neurologic deficits, as previously mentioned. The neurologic outcomes of infants with no other neurologic signs except for tremor seem to be generally good, especially when the infants have no perinatal complications. It appears that tremor in neonates and infants is a functional sign that can be caused by a variety of factors, and the neurologic outcomes are related directly to the underlying brain damage induced by perinatal insults.
