[Metachromatic leukodystrophy. Results of laboratory chemical, neurophysiologic, histologic and imaging procedures within the scope of a family study].

Examining the members of a family the validity of chemical analysis, neurophysiology and neuroimaging for the diagnosis of metachromatic leukodystrophy (MLD) is discussed. As the arylsulfatase A is not decreased in all cases, the neuroimaging (cranial computerized tomography--at a less extend magnetic resonance imaging) gains a particular diagnostic significance. But neither for neuroimaging nor for neurophysiological findings the results are specific. The histological findings have to back up the diagnosis.
