leukoaraiosis

(lū'kō-ahr-ī-ō'sis),
Decreased vascular density, especially in deep white matter in the brain, on MRI or CT; may be caused by demyelination, gliosis, or decreased perfusion.

leukoaraiosis

A late-20th-century term for patches of rarification of white matter caused by multiple focal infarctions due to small vessel disease, which occur in dementia, especially Binswanger type.

Risk factors
Hypertension, smoking, diabetes, hyperhomocysteinemia and heart disease.

Leukoaraiosis is the medical term used to describe white matter hyperintensities in the brain.

Among the topics they discuss are imaging methods and study of higher brain functions, human visual motion organization, Chinese character processing, and aspects of Alzheimer's disease; studies of face perception, language processing and word priming, memory, the kinetic visual field, and visual interpolation ability and leukoaraiosis in healthy subjects; tactile pattern delivery devices in early detection of Alzheimer's disease; and the use of donepezil, Huperzine A, and memantine with Alzheimer's patients.
According to result of research from Hopital Notre Dame in Montreal, two silent factors - leukoaraiosis and silent brain infarcts - can be really tricky and dangerous.
For example, the sensitivities of FA and MD measures have been shown to reveal damage in white matter in ischemic leukoaraiosis abnormalities not noticeable on [T.
The authors focused on a preoperative diagnosis of leukoaraiosis (chronic ischemic white matter changes) by magnetic resonance imaging in the subjects of this study.
The white matter hyperintensities, known as leukoaraiosis, are thought to stem from cerebral small vessel disease.
The white matter hyperintensities, also known as leukoaraiosis, are thought to be a consequence of cerebral small vessel disease.
CADASIL leads to leukoaraiosis (white matter pallor secondary to small vessel occlusive disease) represented by confluent areas of high T2 and fluid-attenuated inversion recovery (FLAIR) signal within the white matter.
Hypertension is a leading risk factor for leukoaraiosis, (56,57,69) as is elevated homocysteine, (70-74) endothelial dysfunction, (75-77) inflammation, (78) abnormal platelet aggregation, (79) and other common vascular toxins.
Subjects with evidence of large-vessel stroke, tumor, focal intracranial lesion, or significant leukoaraiosis, i.
