The disorder is caused by a lack of oxygen or blood flow to the periventricular area of the brain. Jacobson LK, Dutton GN. The white matter in the periventricular regions is involved heavily in motor control, and so individuals with PVL often exhibit motor problems. HHS Vulnerability Disclosure, Help Many infants with PVL eventually develop cerebral palsy. 1978;35(8):517521. [6] One of the earliest markers of developmental delays can be seen in the leg movements of affected infants, as early as one month of age. In cases where perinatal hypoxic brain injury has already occurred, use of hypothermia as neuroprotective treatment has been studied16. Periventricular leukomalacia, or PVL, is a type of brain damage that involves the periventricular white matter of the brain. Other conditions linked to PVL include: In mild cases, some babies may not have any symptoms. Risk factors for white matter changes detected by magnetic resonance imaging in the elderly. Visual impairment with PVL may improve with time. It is important to note that both periventricular and subcortical leukomalacia corresponds to a continuous disease spectrum.

PVL is also the most common cause of cerebral palsy in preterm infants. Vlasyuk (1981) first revealed the high incidence of optic radiation lesions and demonstrated that PVL is a persistent process where old necrosis can join new foci of PVL at different stages of development. These are the spaces in the brain that contain the cerebrospinal fluid (CSF). Ital J Neurol Sci. Because the vascular supply of the periventricular region of the brain in utero remains immature late into term, PVL may arise from neonatal hypoglycemia, hypoxia, seizure, or infection in the third trimester or perinatally5,6.
