Megalencephalic Leukoencephalopathy With Subcortical Cysts
Megalencephalic leukoencephalopathy with subcortical cysts (MLC, or Van der Knaap disease) is a form of hereditary CNS demyelinating disease. It belongs to a group of disorders called leukodystrophies. It is characterized by early-onset enlargement of the head (macrocephaly) as well as delayed-onset neurological deterioration to include spasticity, epilepsy, and lack of muscular coordination. MLC does not appear to be a disease that is fatal at birth or early in life despite its symptoms, although the number of patients throughout history known to have the disease is fairly limited. It belongs to a group of disorders called leukodystrophies. A series of cases with megalencephalic leukodystrophy were described by the Indian neurologist Bhim Sen Singhal (1933-) in 1991. However, it is sometimes referred to as Van der Knaap disease after the Dutch neurologist Marjo van der Knaap who described another series of cases with clinical and radiological features in 1995. There are three ...

Hereditary CNS Demyelinating Disease
A hereditary CNS demyelinating disease is a demyelinating disease, demyelinating central nervous system disease that is primarily due to an inherited genetic condition. (This is in contrast to autoimmune demyelinating conditions, such as multiple sclerosis, or conditions such as central pontine myelinolysis that are associated with acute acquired insult.) Examples include: * Alexander disease * Canavan disease * Krabbe disease * leukoencephalopathy with vanishing white matter * megalencephalic leukoencephalopathy with subcortical cysts * metachromatic leukodystrophy * X-linked adrenoleukodystrophy References External links
