White Matter Hyperintensities on MRI – Coincidental Finding or Something Sinister?

Posted on May 26, 2017

White matter hyperintensities (WMHs) are lesions in the brain that show up as areas of increased brightness when visualised by T2-weighted magnetic resonance imaging (MRI).

WMH’s are also referred to as Leukoaraiosis and are often found in CT or MRI’s of older patients. The prevailing view is that these intensities are a marker of small-vessel vascular disease and in clinical practice, are indicative of cognitive and emotional dysfunction, particularly in the ageing population.

The initial discovery of WMH’s was made in the late 1980’s by Hachinski and colleagues. They described WMH’s as patchy low attenuation in the periventricular and deep white matter.

    well my partner has been just having some health issues and they did MRI and they came up with some white matter spots. She is losing balance as well as her eye sight not the best – double vision.
    is there are a way how to manage it- change of diet – what kind of diet etc. I know she dosnt have best diet although skinny. or medication?
