It is also a risk period for intracranial hemorrhage, which can range in severity from general and benign to potentially destructive. Intracranial hemorrhage (ICH) is a common neurological lesion in neonatology, with periventricular-intraventricular hemorrhage (PVH-IVH) being the most common.

The pathogenesis of neonatal ICH is complex, understand preterm birth.
