<unk>  is a demyelinating disease, in which the myelin sheath covering the axons of nerve cells is gradually destroyed, impairing the transmission of nerve impulses. It affects the subcortical white matter, particularly that of the parietal and occipital lobes.<unk>  destroys oligodendrocytes and produces intranuclear inclusions. It is similar to another demyelinating disease, MS, but progresses much more quickly. The breakdown of myelin is proportional to the degree of immunocompromise.
