The term "leukoaraiosis" was coined in 1986 [6] [7] by Hachinski, Potter, and Merskey as a descriptive term for rarefaction ("araiosis") of the white matter, showing up as decreased density on CT and increased signal intensity on T2/FLAIR sequences (white matter hyperintensities) performed as part of MRI brain scans. These white matter changes ...
Brain ischemia has been linked to a variety of diseases or abnormalities. Individuals with sickle cell anemia, compressed blood vessels, ventricular tachycardia, plaque buildup in the arteries, blood clots, extremely low blood pressure as a result of heart attack, and congenital heart defects have a higher predisposition to brain ischemia in comparison to the average population.
These types of strokes include lacunar and other ischemic strokes and minor hemorrhages. They may also include leukoaraiosis (changes in the white matter of the brain): the white matter is more susceptible to vascular blockage due to reduced amount of blood vessels as compared to the cerebral cortex.
A new study examines how age-related brain changes could be linked to stroke recovery. Researchers suggest areas of age-related damage to parts of the brain containing white matter may influence ...
The integrity of white matter declines due to aging. [19] Nonetheless, regular aerobic exercise appears to either postpone the aging effect or in turn enhance the white matter integrity in the long run. [19] Changes in white matter volume due to inflammation or injury may be a factor in the severity of obstructive sleep apnea. [20] [21]
Researchers collected MRI data to evaluate brain white matter health and ... “This can be interpreted as superagers can avoid the normal ageing changes that occur in white matter microstructure ...
Binswanger's disease, also known as subcortical leukoencephalopathy and subcortical arteriosclerotic encephalopathy, [1] is a form of small-vessel vascular dementia caused by damage to the white brain matter. [2] White matter atrophy can be caused by many circumstances including chronic hypertension as well as old age. [3] This disease is ...
Periventricular leukomalacia (PVL) is a form of white-matter brain injury, characterized by the necrosis (more often coagulation) of white matter near the lateral ventricles. [1] [2] It can affect newborns and (less commonly) fetuses; premature infants are at the greatest risk of neonatal encephalopathy which may lead to this condition.
