Cranial imaging is not used for diagnosis of this condition. However, if an MRI is performed, it may show cortical restricted diffusion with unusual characteristics of reversible T2 hypointensity in the subcortical white matter. [10]
White matter is the tissue through which messages pass between different areas of grey matter within the central nervous system. The white matter is white because of the fatty substance (myelin) that surrounds the nerve fibers (axons). This myelin is found in almost all long nerve fibers, and acts as an electrical insulation.
The European Leukodystrophy Association also supports research into leukodystrophy. As of 2020, more than 387 research projects have been funded. Each year, ELA invites the international scientific community to submit research projects in the field of genetic leukodystrophies, the cerebral white matter in premature infants, and of myelin repair ...

Head CT showing periventricular white matter lesions. Leukoaraiosis is a particular abnormal change in appearance of white matter near the lateral ventricles. It is often seen in aged individuals, but sometimes in young adults. [1] [2] On MRI, leukoaraiosis changes appear as white matter hyperintensities (WMHs) in T2 FLAIR images.
Evidence from subcortical small infarcts suggests that motor fibers are somatotopically arranged in the human corona radiata. Following subtotal brain damage, localization of the corticofugal projection in the corona radiata and internal capsule can assist in evaluating a patient's residual motor capacity and predicting their potential for functional restitution.
For example, deep white matter hyperintensities are 2.5 to 3 times more likely to occur in bipolar disorder and major depressive disorder than control subjects. [3] [4] WMH volume, calculated as a potential diagnostic measure, has been shown to correlate to certain cognitive factors. [5]
The ependyma is the thin neuroepithelial (simple columnar ciliated epithelium) lining of the ventricular system of the brain and the central canal of the spinal cord. [1] The ependyma is one of the four types of neuroglia in the central nervous system (CNS).
