Traditionally, the cerebellum has been regarded as a central component of the motor system. Recent studies suggest an important role played by the cerebellum in the development of cognitive and social functions. The objective of this study was to evaluate the incidence of cerebellar injury and to define the obstetrical, neonatal, and radiologic characteristics, as well as the functional outcomes in a population of very preterm infants. METHODS This retrospective study included neonates born before 30 weeks of gestational age between March 2004 and July 2007. Infants underwent MRI studies at a term-adjusted age; for each preterm infant with cerebellar injury, we identified two infants for the control group with normal MRI, matched on the basis of gestational age. We collected pertinent demographic, prenatal, and acute postnatal data for all infants. Follow-up assessment was performed at 2 years, using the Brunet-Lezine scale. RESULTS A total of 148 ex-preterm infants were studied. Cerebellar injury was present in 14 (9 %) cases and associated with supratentorial parenchymal injury in 90 %. Duration of ventilation was longer in children with cerebellar injury, compared to controls (19.5 days vs 16.5 days; P=0.03). The other neonatal criteria analyzed were comparable between the two groups. Global developmental, functional, and social-behavioral deficits were more common and profound in preterm infants with cerebellar injury, with no significant difference. CONCLUSIONS This study confirms the high incidence of cerebellar injury in very preterm infants and the importance of a specific neurobehavioral follow-up.

D002531 Cerebellum The part of brain that lies behind the BRAIN STEM in the posterior base of skull (CRANIAL FOSSA, POSTERIOR). It is also known as the "little brain" with convolutions similar to those of CEREBRAL CORTEX, inner white matter, and deep cerebellar nuclei. Its function is to coordinate voluntary movements, maintain balance, and learn motor skills. Cerebella,Corpus Cerebelli,Parencephalon,Cerebellums,Parencephalons
D002658 Developmental Disabilities Disorders in which there is a delay in development based on that expected for a given age level or stage of development. These impairments or disabilities originate before age 18, may be expected to continue indefinitely, and constitute a substantial impairment. Biological and nonbiological factors are involved in these disorders.

D005865 Gestational Age The age of the conceptus, beginning from the time of FERTILIZATION. In clinical obstetrics, the gestational age is often estimated from the onset of the last MENSTRUATION which is about 2 weeks before OVULATION and fertilization. It is also estimated to begin from fertilization, estrus, coitus, or artificial insemination.

D012189 Retrospective Studies Studies used to test etiologic hypotheses in which inferences about an exposure to putative causal factors are derived from data relating to characteristics of persons under study or to events or experiences in their past. The essential feature is that some of the persons under study have the disease or outcome of interest and their characteristics are compared with those of unaffected persons.
