Many studies examine the trends in outcomes of individuals with PVL: a recent study by Hamrick, et al., considered the role of cystic periventricular leukomalacia (a particularly severe form of PVL, involving development of cysts) in the developmental outcome of the infant. PVL may happen before, during or after birth. This pathology of the brain was described under various names ("encephalodystrophy", "ischemic necrosis", "periventricular infarction", "coagulation necrosis", "leukomalacia," "softening of the brain", "infarct periventricular white matter", "necrosis of white matter", "diffuse symmetrical periventricular leukoencephalopathy"), and more often by German scientists, but the worldwide dissemination was the term periventricular leukomalacia, introduced in 1962 B.

Consequently, functional defects in patients with PVL are highly dependent on location of insult. Novosibirsk, Nauka, 1985 .- 96 p. Hamrick S, MD. [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. The processes affecting neurons also cause damage to glial cells, leaving nearby neurons with little or no support system. [22], Other ongoing clinical studies are aimed at the prevention and treatment of PVL: clinical trials testing neuroprotectants, prevention of premature births, and examining potential medications for the attenuation of white matter damage are all currently supported by NIH funding.

[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. The term can be misleading, because there is no softening of the tissue in PVL. xo marriage conference 2022 schedule,
