Brain and spinal cord white matter are vulnerable to the effects of ischaemia. Reduction of the energy supply leads to a cascade of events including depolarization, influx of Na(+) and the subsequent reverse operation of the membrane protein the Na(+)/Ca(2+) exchanger which ultimately terminates in intracellular Ca(2+) overload and irreversible axonal ...

"Vanishing white matter" (VWM) is a leukodystrophy caused by autosomal recessive pathogenic variants in the genes encoding the subunits of eukaryotic initiation factor 2B (eIF2B). Disease onset and disease course are extremely variable. Onset varies from the antenatal period until senescence. The age of onset is predictive of disease severity.

Current opinion in neurology and neurosurgery, 1991
Magnetic resonance imaging (MRI) has a leading role in the diagnosis of white matter disorders because of its superior sensitivity. It also allows a detailed analysis of white matter disorders, improving the specificity of the diagnoses. There is an increasing knowledge about MRI patterns, in particular in hereditary metabolic disorders.

White matter lactate – Does it matter?
Neuroscience, 2014About half of the human brain is white matter, characterized by axons covered in myelin, which facilitates the high speed of nerve signals from one brain area to another. At the time of myelination, the oligodendrocytes that synthesize myelin require a large amount of energy for this task.

American Journal of Psychiatry, 2007
The axonal membrane and the myelin sheets around axons restrict water diffusion perpendicular to the fiber orientation in white matter but not along the axon’s main axis, which leads to anisotropic diffusion of water. Over the last decade, the quantitative measurement of this anisotropy by using what has been called diffusion tensor imaging (DTI) has ...

Multifocal white matter lesions
Seminars in Ultrasound, CT and MRI, 1996There is a long differential diagnosis for multifocal white matter lesions on MR. The most common causes are prominent Virchow-Robin spaces, white matter ischemic change, and multiple sclerosis, but many other causes have been reported. Most of these are related to vascular or other demyelinating etiologies, but infectious/inflammatory disease, trauma,

Australian Feminist Studies, 2006
The author examines the responses to her book "Talkin' up to the White Woman: Indigenous Women and Feminism." She analyzes the nine out of almost 30 reviews written about her book which talks about power relations between white feminists and indigenous women.

Science, 2003
Scientists have long known that connections somehow go awry in the brains of people with schizophrenia. Now advances in imaging and gene technology are allowing them to trace the axons that connect from neuron to neuron and make up the brain9s white matter.

Cerebral White-Matter Hypoplasia
Archives of Neurology, 1977Twelve patients, including three sisters, with lifelong severe intellectual impairment and neurologic defects were found to have generalized hypoplasia of the cerebral white matter, with corresponding enlargement of the ventricular system. Gray-matter structures were remarkably intact.

Do white cells matter in white matter damage?
Trends in Neurosciences, 2001Support is provided for the hypothesis that activated leukocytes, especially monocytes/macrophages, contribute to cerebral white matter damage in extremely low gestational age newborns. Much of the evidence is indirect and comes from analogies to brain diseases in adults, and from models of brain damage in adult and newborn animals.
