Metachromatic leukodystrophy

Common Name(s)

Metachromatic leukodystrophy, MLD, Arylsulfatase A Deficiency, ARSA deficiency, Greenfield's disease

Metachromatic leukodystrophy is an inherited condition characterized by the accumulation of fats called sulfatides in cells, especially cells of the nervous system. This accumulation results in progressive destruction of white matter of the brain, which consists of nerve fibers covered by myelin. Affected individuals experience progressive deterioration of intellectual functions and motor skills, such as the ability to walk. They also develop loss of sensation in the extremities, incontinence, seizures, paralysis, inability to speak, blindness, and hearing loss. Eventually they lose awareness of their surroundings and become unresponsive. This condition is inherited in an autosomal recessive pattern and is caused by mutations in the ARSA and PSAP genes.

Journal: AJNR Am J Neuroradiol. 2012 Oct;33(9):1731-9.

 

The prospect of new therapies in MLD stresses the need to refine the indications for treatment. The aim of this study was, therefore, to perform a detailed analysis of MRI brain lesions at diagnosis and follow-up, to better understand the natural history of MLD.
