The understanding of the genetic basis of late-onset leukoencephalopathies has continued
to increase in recent years. The most commonly presenting leukoencephalopathies in
adulthood can be late-onset manifestations of metabolic pathways. The understanding
of these diagnoses is crucial to the evaluation of adult patients presenting with
leukoencephalopathies. The authors provide an overview of the common leukoencephalopathies
in adulthood, the current understanding of the pathology, and genetics of these disorders
with typical imaging findings. When available, treatment options will be discussed.
