Leukoaraiosis

Posted by iskanbasal on April 12, 2008

I have benn interested in reading this articel in the last period:

Leukoaraiosis

Practical Neurology 2008;8:26-38; doi:10.1136/jnnp.2007.139428

Mike O’Sullivan

ABSTRACT

” 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. Neurologists often come across this appearance, but its significance is sometimes uncertain. The effects on cognitive function and gait are insidious and can be difficult to detect at the bedside, but are nevertheless important. However, gradually it is becoming clearer how leukoaraiosis relates to cerebrovascular disease, Alzheimer’s and other diseases, and how this appearance should influence treatment decisions. ..

My interest was to know more about the interpretation of this MRI finding which is called “Leukoaraiosis” as I saw it was discussed in the clinic by the neuroradiologists with neurologists, especially when images is done in the elderly. Leukoaraiosis comes from Greek, LEUKO means white while ARAIOSIS: rarefaction.
