[Adult metachromatic leukodystrophy manifested as schizophrenic psychosis (author's transl)]

Abstract

An autopsy case of adult metachromatic leukodystrophy (MLD) manifested clinically as schizophrenic psychosis is reported. A 50-year-old man developed progressive mental changes 10 years before his death, and later manifested a schizophrenic syndrome without neurologic deficits or EEG changes. After his death from uremia neuropathology disclosed MLD with demyelination accentuated in the frontal lobes and abundant metachromatic deposits in the preserved areas of cerebral white matter. Neurochemical examination of the demyelinated frontal area showed reduced concentration of cerebrosides and sulfatides, decreased amounts of total lipids in the tissue, and an increase of sulfatides, and particularly of their cerebron fractions in lipid extract. The problems of adult forms of MLD with prolonged course are discussed with special reference to cases showing mainly psychiatric syndromes.
