Metachromatic Leukodystrophy (MLD)
Archives of Neurology, 1968ADULTS, as well as children, develop metachromatic leukodystrophy (MLD). Does the adult with MLD also have a sulfatase A deficiency? If he does, can this enzyme deficiency really explain his illness? For example, if one presumes that the enzymic defect is inborn, why did his symptoms not begin when he was a child?

The first aim of this study was to obtain a more detailed picture of the effect of masker bandwidth (20 Hz to 1000 Hz bandwidth) on the masking level difference (MLD) for a 500-Hz signal as a function of listener age. The results of the pure-tone signal experiment showed that the MLDs of older children differed from adults only for the narrowest masker

MLDs in Forward and Backward Masking
The Journal of the Acoustical Society of America, 1972Masking-level differences (MLDs) of substantial magnitudes were found in forward and backward masking situations. Their magnitude diminishes exponentially as the silent interval between signal and masker increases. Implications of the data for current models relating to the MLD are suggested.

Metachromatic Leukodystrophy (MLD)
Archives of Neurology, 1971METACHROMATIC leukodystrophy (MLD) is characterized by deficient activity of sulfatase A (arylsulfatase A; cerebroside sulfatase) and by a corresponding accumulation of cerebroside sulfate. The disease begins at different ages and evolves at different tempos. Late infantile, juvenile, adult, and variant forms occur.

Several experiments have shown that the S0M0-SπM0 MLD increases markedly with reduction in masker bandwidth. However, there are at least two inconsistencies in this result. First, apparently similar experiments conducted by different laboratories have produced quite different results.
