The influence of low arylsulfatase A activity on neuropsychiatric morbidity: a large-scale screening in patients.
A total of 1728 patients consecutively admitted to a neuropsychiatric hospital and 379 chronically ill inpatients were examined for activity of arylsulphatase A (ASA) in leucocytes. A further 519 healthy individuals served as controls. We did not find evidence for the involvement of low ASA activity in chronic patients. The consecutive admissions showed a slight preponderance in the lower ASA activity classes. This activity range covers persons heterozygous for ASA deficiency alleles. The data are compatible with the hypothesis that carriers of low ASA activity alleles are at a slightly higher risk for neuropsychiatric disorders.
