title: Rapid progression of parkinsonism associated with an increase of blood manganese.
abstract: In this paper, we report a 72-year-old man whose parkinsonian pictures accelerated rapidly after an ingestion of unknown herb pills. His serum manganese and aluminum level increased 2-fold and 5-fold over physiological level respectively. A reverse of his parkinsonian deterioration was accompanied with a normalization of these metals. Exclusive heavy metals have been widely mentioned in parkinsonism. While industrial source of these metals has extensively been sought, pharmacology is rarely mentioned in this aspect, especially of herb medicine origin. We suggest that an acceleration of parkinsonian pictures should raise the need to re-evaluate the possibility of heavy metal intoxication in parkinsonism. Besides of industrial contamination, we should be alert for the nonindustrial source in our population.
