If you have any questions about this condition or cardiovascular disease risk factors, ask your healthcare provider. Visual rating of age-related white matter changes on magnetic resonance imaging: scale comparison, interrater agreement, and correlations with quantitative measurements. How long does it take for chorionic villus sampling results to come back? For example, some studies have shown that those with T2 hyperintensities perform more poorly on certain tests of mental agility than those without. The site is secure. Age-related change in the frontal lobe is associated with poorer executive function (e.g., working memory, switching/set-shifting, and inhibitory control). Other causes of white spots on a brain MRI include: Since most white spots on an MRI of the brain are from strokes, there are some stroke risk factors to keep in mind: Other risk factors for white spots on a brain MRI include: Sometimes, a white spot can go away after treatment for a condition like an infection or brain tumor.

T2 - An indication of the type of scan that was done. This study aims to examine the correlation of WMHs with migraine features and explore the relationship between WMHs and migraine prognosis. The surface and deep areas of your brain contain gray matter, which gets its color from the cell bodies of neurons. MRI uses a large magnet, radio waves and a computer to produce these detailed images without any radiation (does not use X-rays). width: "100%", Methods The orientation of many lesions is perpendicular to the lateral ventricles (arrows in Fig. (https://www.brainandlife.org/articles/what-are-white-matter-lesions-are-they-a-problem). We also need trials of interventions that may reduce WMH burden or progression, and these trials should have clinical outcomes (cognitive impairment, stroke, death). . White matter disease is the wearing away of tissue in the largest and deepest part of your brain that has a number of causes, including aging. White matter disease is strongly linked to cardiovascular disease risk factors, and researchers believe that white matter disease is a biomarker (medical sign) of the lifelong risk of stroke, dementia and disability.
