Distinguishing leukoencephalopathies from normal age-dependent changes in myelination can be challenging. In addition, how well cortical dysplasias are seen on the MRI may be related to the degree of myelination. WebYet as degeneration occurs, other changes, such as the formation of redundant myelin and increasing thickness suggest of sheaths, suggest some myelin formation is continuing during aging. Another indication of this is that oligodendrocytes increase in number with age.
