Leukoaraiosis and acute ischemic stroke

European Journal of Neuroscience, 2021
Abstract Ischaemic stroke is characterized by high morbidity, high disability rate, high mortality and high recurrence rate, which can have a grave impact on the quality of life of the patients and consequently becomes an economic burden on their families and society.

Leukoaraiosis

2002
Abstract Leukoaraiosis is a term coined by Hachinski et al. (1987) from the Greek roots ‘leuko’ (white) and ‘araiosis’ (rarefied) to describe the radiological appearances of patchy or diffuse abnormalities in the deep white matter, which appear as low attenuation on computed tomography (CT) or high intensity signals on T2-weighted ...

Apoptosis in leukoaraiosis lesions

Journal of the Neurological Sciences, 2002
Leukoaraiosis (LA), an age-related degenerative condition, appears as an area of hyperintense signal in the deep white matter on MRI. It may be caused by chronic ischemia. LA lesions are characterized by demyelination, loss of glial cells, spongy appearance, and occlusion of veins and venules by collagenous thickening of the vessel walls.

Leukoaraiosis. A Short Review

Rivista di Neuroradiologia, 2005
Leukoaraiosis (LA) is the widely accepted definition for the changes in the white matter of the brain frequently detected in the elderly by neuroimaging techniques. LA has a vascular pathogenesis and is a definite contributory factor for stroke, cognitive decline and dementia. Theoretically, though not yet in practice, if these lesions are detected at

Leukoaraiosis and stroke outcome

Journal of Stroke and Cerebrovascular Diseases, 2002
We studied the influence of leukoaraiosis on the prognosis of stroke for the first year after onset. Three hundred and seventy consecutive stroke subjects were observed for 1 year. Data were collected prospectively in a questionnaire constructed in accordance with the Stroke Data Bank and analyzed using SPSS.

Leukoaraiosis with mild cognitive impairment

Neurological Research, 2015
As the ageing population continues to increase, the prevalence of age-related cognitive impairment has been on the rise. Mild cognitive impairment (MCI) is now widely recognised as the early stage of dementia. Mild cognitive impairment is closely associated with cerebral white matter lesions (WMLs), specifically in the case of leukoaraiosis (LA).

Leukoaraiosis and vascular dementia

Neurology, 1998
The emergence of sensitive techniques for brain imaging has drawn attention to the occurrence of diffuse or multifocal changes affecting the cerebral white matter. The white matter changes are usually termed periventricular leukoencephalopathy, or leukoaraiosis.

Skin Biopsy Value and Leukoaraiosis

Annals of the New York Academy of Sciences, 2000
Abstract: In the field of leukoaraiosis, the identification of CADASIL and its link to Notch 3 mutation has shed light on the pathogenesis of white matter (WM) abnormalities related to small‐vessel disease. Since 1993, its systemic vascular involvement allows skin biopsy diagnosis and research on tissues before postmortem examination.

Cognitive correlates of leukoaraiosis

Cerebrovascular Diseases, 1997
Leukoaraiosis (LA) means decreased density of the white matter of brain. It is seen as hypodensity on computed tomography (CT) scans and as hyperintensity on T2-weighted magnetic resonance imaging (MRI) scans. When Hachinski et al. [1] coined the term in 19 87, it referred to the diffuse or patchy hypodensities seen in the deep white matter on CT scans

Reduced noncovalent connections in leukoaraiosis

Expert Review of Neurotherapeutics, 2008
Leukoaraiosis is manifested as diffuse areas of hypodensity on CT scans and as hyperintensity signals on T2-weighted MRI scans. This neuroimaging phenomenon is frequently associated with cognitive decline in the middle-aged or elderly. Ischemic demyelinization or chronic perivascular toxic edema in the white matter of the brain is presumed to be behind
