Clinical research uses human volunteers to help researchers learn more about a disorder and perhaps find better ways to safely detect, treat, or prevent disease. Consequent cell death and thinning of white matter around the ventricles leaves fluid-filled spaces called lateral ventricles9. However, the correction of these deficits occurs "in a predictable pattern" in healthy premature infants, and infants have vision comparable to full-term infants by 36 to 40 weeks after conception. Moreover, some adult treatments have actually been shown to be toxic to developing brains. Between 4 and 26% of premature babies placed in neonatal intensive care units have cerebral palsy.

If you are uploading a letter concerning an article: The features of PVL in childhood are described elsewhere and this article will review the neuro-ophthalmic features of PVL in adult patients who may present later in life with otherwise unexplained findings that may mimic adult strabismus or optic neuropathy . Therefore, it is essential to raise awareness of PVL as a possible cause of strabismus, visual deficit and cupping in patients with history of prematurity and perinatal complication. Periventricular leukomalacia causes holes and serious damage to the brain. Personal Interview. The initial hypoxia (decreased oxygen flow) or ischemia (decreased blood flow) can occur for a number of reasons. 2018 May 15;134(Pt B):218-225. doi: 10.1016/j.neuropharm.2017.11.009. A rat model that has white matter lesions and experiences seizures has been developed, as well as other rodents used in the study of PVL. Findings are usually consistent with white matter loss and thinning of periventricular region. Periventricular leukomalacia causes cell damage to the brain's periventricular tissue as well as a decrease in blood flow. Delayed motor development of infants affected by PVL has been demonstrated in multiple studies. [1, 2] In relatively recent years, this terminology has been somewhat controversial, as PVL reflects a categorization by neuropathologic findings.There have been suggestions that "white matter injury" be used instead, of which PVL would be a subcategory. Periventricular leukomalacia, or PVL, is a type of brain damage that involves the periventricular white matter of the brain. 2013;61(11):634-635. doi:10.4103/0301-4738.123146, 15.

Periventricular leukomalacia (PVL) is a type of brain injury that is most common in babies born too soon (premature) or at low birthweight. Researchers have begun to examine the potential of synthetic neuroprotection to minimize the amount of lesioning in patients exposed to ischemic conditions.[15]. Susceptibility can be attributed, at least in part, to a relative deficiency of superoxide dismutases in the preterm white matter, including premyelinating oligodendrocytes. Reference 1 must be the article on which you are commenting. Some children exhibit fairly mild symptoms, while others experience significant disabilities. National Cerebral Palsy Awareness Month (and Awareness Day on March 25) was created by Reaching for the Stars in 2006. government site. Periventricular leukomalacia can lead to physical and mental development issues. Acta Neuropathol. Many infants with PVL eventually develop cerebral palsy. The white matter (leuko) surrounding the ventricles of the brain (periventricular) is deprived of blood and oxygen leading to softening (malacia). Cerebral visual impairment in PVL typically occurs because of afferent visual pathway injury to the optic radiations, which travel adjacent to the lateral ventricles7. Huang J, Zhang L, Kang B, Zhu T, Li Y, Zhao F, Qu Y, Mu D. PLoS One. Online ISSN:1526-632X, The most widely read and highly cited peer-reviewed neurology journal.
