Hi there. I empathize with you and understand your predicament. The diagnosis can be confirmed by decreased arylsulfatase A enzyme activity in leukocytes or in cultured skin fibroblasts. Brain MRI to identify white matter lesions and atrophy, nerve conduction studies and neuropsychological testing. biopsy specimens from peripheral nerves, kidney and gall bladder show metachromatic granules . This is a terminal disease and no standard treatment is there. Pain and symptom management and for presymptomatic and mild to moderate symptoms, bone marrow transplantation including stem cell transplantation which may slow down disease progression or CNS progression. Certain options are still under investigation like gene therapy and enzyme replacement therapy etc. Take care and all the best.
