Please refer to the article on patterns of . Periventricular Leukomalacia (PVL) and Cerebral Palsy The clinical model of periventricular leukomalacia as a distinctive form of cerebral white matter injury is important for understanding cognitive and social functioning in typical and atypical development because (i) compared with lesions acquired later in life, the model deals with brain damage of early origin (early-to-middle third trimester . Single-Cell Analysis of the Neonatal Immune System Across the Gestational Age Continuum. Because their cardiovascular and immune systems are not fully developed, premature infants are especially at risk for these initial insults. Periventricular Leukomalacia (PVL) - Children's Hospital of Philadelphia Leech R, Alford E. Morphologic variations in periventricular leukomalacia.

These include free radical injury, cytokine toxicity (especially given the epidemiologic association of PVL with maternofetal infection), and excitotoxicity. November 18, 2008. leukomalacia: ( l-k-m-l'sha ), Disorder involving softening of brain white matter. The optic radiations, which may be damaged in the periventricular region, originate from the lateral geniculate nuclei and are topographically organized both anatomically and functionally. A fetus or infant who suffers from this condition may develop neurological disorders, cerebral palsy, vision and hearing problems, and disabilities.
