White matter refers to axon tracts and commissures. Long thought to be passive tissue, it actively affects learning and brain functions, modulating the distribution of action potentials, acting as a relay and coordinating communication between different brain regions. White matter is named for its relatively light appearance resulting from the lipid content of myelin. However, the tissue of 2020-11-18 · COVID-19 patients’ brains showed N-acetyl-aspartate (NAA) reduction, choline elevation, and myo-inositol elevation, similar to what is seen with these metabolites in other patients with white matter abnormalities (leukoencephalopathy) after hypoxia without COVID.

Areas of brain damage called white matter hyperintensities are commonly linked to vascular health problems. They have also been linked to Alzheimer’s disease. Now a new study has shown that white matter hyperintensities are also found in frontotemporal dementia. The study is published in the February 17, 2021, online issue of Neurology.
