[17] More white matter damage leads to more severe cerebral palsy; different subtypes are identified and diagnosed by a neurologist. Early and late CT manifestations in the persistent vegetative state due to cerebral anoxia-ischemia. The extent of signs is strongly dependent on the extent of white matter damage: minor damage leads to only minor deficits or delays, while significant white matter damage can cause severe problems with motor coordination or organ function. However, neuro-ophthalmic presentation of PVL is highly variable. Periventricular significa alrededor o cerca de los ventrculos . Moreover, some adult treatments have actually been shown to be toxic to developing brains. [15], Current clinical research ranges from studies aimed at understanding the progression and pathology of PVL to developing protocols for the prevention of PVL development. Brain injury - Damage to the white matter brain tissue. Only 7.8% of patients who had no identified cerebrovascular risk factors and who reported no cerebrovascular symptoms had these MRI periventricular lesions; 78.5% of patients with a history of cerebrovascular risk factors and who had had cerebrovascular symptoms had periventricular patterns.

Cerebral white matter lesions seen in the perinatal period include periventricular leukomalacia (PVL), historically defined as focal white matter necrosis, and diffuse cerebral white matter gliosis (DWMG), with which PVL is nearly always associated. Delayed motor development of infants affected by PVL has been demonstrated in multiple studies. The site is secure. Because neural structures are still developing and connections are still being formed at birth, many medications that are successful for treatment and protection in the adult central nervous system (CNS) are ineffective in infants.

Periventrivular leukomalacia (PVL) refers to focal or diffuse cerebral white matter damage due to ischemia and inflammatory mechanisms (Volpe, 2009a,c ). Periventricular leukomalacia (PVL) is a form of white-matter brain injury, characterized by the necrosis . It is proposed that the prolonged hypoxia and ischemia produce a "no reflow" phenomenon causing brain edema (more pronounced in the white matter); this resulted in infarctions of white matter in the periventricular arterial end and border zones.

The disorder is caused by a lack of oxygen or blood flow to the periventricular area of the brain. These are the spaces in the brain that contain the cerebrospinal fluid (CSF). 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.

Periventricular Leukomalacia, or PVL - CerebralPalsy.org Brain Pathol 15: 225-233. Two major factors appear to be involved in the development of PVL: (1) decreased blood or oxygen flow to the periventricular region (the white matter near the cerebral ventricles) and (2) damage to glial cells, the cells that support neurons throughout the nervous system. White matter transmits information between nerve cells, the spinal cord, and from one part of brain to the other. 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. However, other differential diagnoses include ischemic, infectious, inflammatory, compressive, congenital, and toxic-nutritional etiologies. In an Israel-based study of infants born between 1995 and 2002, seizures occurred in 102 of 541, or 18.7%, of PVL patients. The white matter is the inner part of the brain. Because white matter injury in the periventricular region can result in a variety of deficits, neurologists must closely monitor infants diagnosed with PVL in order to determine the severity and extent of their conditions.
