4 mai 2022 · White matter disease is damage to your brain’s white matter caused by reduced blood flow and nutrients. It can affect memory, balance and mobility and is linked to cardiovascular risk factors. Learn more about the diagnosis, prevention and outlook of this condition.
21 mar. 2023 · Periventricular white matter lesions are areas of brain damage that can be seen on MRI scans. They are often caused by small vessel disease, hypertension, smoking, diabetes, or HIV, and may affect cognitive function.
Learn what periventricular white matter is, where it is located, and what changes can occur in it. Find out the possible causes, symptoms, and diagnosis of periventricular white matter abnormalities.
Recent in vivo imaging studies provide supportive evidence that periventricular white matter lesions are associated with cortical cholinergic deafferentation in elderly with leukoaraiosis. White matter lesions at the frontal horns, so-called “capping,” are in close proximity to cholinergic axons that originate in the basal forebrain.
7 mar. 2024 · Periventricular-white matter hyperintensity (PV-WMH) is featured by gliosis, loosening of the WM, and loss around convoluted venules in perivascular spaces. In contrast, the primary characteristics of deep subcortical-white matter hypersensitivity (DS-WMH) are demyelination, gliosis, and augmented tissue loss as the lesions become serious.
14 apr. 2022 · White matter disease is the wearing away of tissue in the brain that connects other parts of the nervous system. It can affect thinking, walking, and balance and is linked to aging, blood pressure, diabetes, and smoking.
Changes in the white matter of presumed vascular origin were first identified as hypoattenuation of the white matter on computed tomography but now are more often seen as patchy areas of signal hyperintensity in deep and periventricular white matter areas on T2-weighted sequences, particularly fluid-attenuated inversion recovery.
