Brain magnetic resonance imaging (MRI) is the main way healthcare providers diagnose white matter disease. An MRI scan is a painless test that produces very clear images of different parts of your body. MRI uses a large magnet, radio waves and a computer to produce these detailed images without any radiation (does not use X-rays).
White matter disease is commonly detected on brain MRI of aging individuals as white matter hyperintensities (WMH), or ‘leukoaraiosis.” Over the years it has become increasingly clear that the presence and extent of WMH is a radiographic marker of small cerebral vessel disease and an important predictor of the life-long risk of stroke, cognitive impairment, and functional disability.
Feb 16, 2022 · A magnetic resonance imaging (MRI) scan of each participant’s brain was taken each week throughout the study, allowing the researchers to observe subtle changes over time. The brain scans revealed evidence of tiny strokes appearing in the white matter of most participants over time, yet the participants did not experience any symptoms.
This test involves lying on a table for several minutes while a small x-ray detector scans your spine, hip or forearm. You may be asked to lift your legs onto a support to straighten your back for the test or internally rotate your legs to provide a larger surface area for your hip measurement.

Jun 3, 2016 · The term white matter dementia (WMD) was introduced in 1988 to highlight the role of white matter in the development of dementia. As the concept has been refined with new insights into the structure and function of normal and abnormal white matter, research has expanded to consider normal cognition, network connectivity, novel treatment ideas, and the etiopathogenesis of neurodegenerative ...
