Computed tomography and magnetic resonance imaging of the brains of elderly individuals frequently show areas of altered signal intensity in the periventricular and subcortical white matter, referred to as leukoaraiosis. Although mildly affected individuals appear asymptomatic, larger burdens of leukoaraiosis are associated with deficits of cognition ...

Altered signal intensity in the subcortical white matter on magnetic resonance imaging of the brain, referred to as leukoaraiosis, is frequently observed on imaging studies in elderly persons and was previously considered a benign accompaniment of aging. However, recent studies have found a clear association between the presence of leukoaraiosis and an

We report a case of leukoaraiosis that was studied for apoptosis. In the neuropil, the number of cells that showed DNA fragmentation was 2.5 times as great in the area of leukoaraiosis as in the adjacent white matter (P = .004) and 25 times as great as in the nearby cortex (P < .001).

LEUKOARAIOSIS IN STROKE PATIENTS
International Journal of Neuroscience, 2003Pathogenesis of leukoaraiosis (LA) is not clearly understood and its significance in patients with stroke remains undetermined. In the Neurology Department of Ankara Hospital, computed tomography (CT) examination of brain was performed for various reasons in 288 patients. LA was detected in 178 patients by the use of brain CT.

Leukoaraiosis describes diffuse white matter abnormalities on CT or MR brain scans, often seen in the normal elderly and in association with vascular risk factors such as hypertension, or in the context of cognitive impairment. The term was introduced to avoid confusing an imaging appearance with a specific pathology.

Leukoaraiosis and stroke outcome
Journal of Stroke and Cerebrovascular Diseases, 2002We 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.

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 ...

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.

Apoptosis in leukoaraiosis lesions
Journal of the Neurological Sciences, 2002Leukoaraiosis (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.
