Recent advances in magnetic resonance imaging (MRI) techniques have prompted reconsideration of the anatomical correlates of adverse outcomes in preterm infants. The importance of the contribution made by the cerebellum is now increasingly appreciated. The effect of cerebellar haemorrhage (CBH)on the microstructure of the cerebellar-cerebral circuit is largely unexplored.
Objectives: To investigate the effect of CBH on the microstructure of cerebellar-cerebral connections in preterm infants aged <32 gestational weeks.
Conclusion:This study provides evidence that CBH causes alterations in localised and remote WM pathways in the developing brain. The disruption of the cerebellar-cerebral microstructure at multiple sites adds further support for the concept of developmental diaschisis, which is propagated as an explanation for the consequences of early cerebellar injury on cognitive and affective domains.
