Abstract

ABSTRACT. Mental retardation and dementia characteristic of Down's syndrome (DS) have a complex pathogenesis. Golgi and immunohistochemical studies were done on DS patients and controls from foetuses and elderly adults. Golgi studies on the cerebral cortex revealed that the postsynaptic spines on the basal dendrites increase from neonate to 15 years of age and gradually decrease after 20 years in controls, but poorly increase in children and rapidly decrease in adults with DS. This deficient synaptogenesis and dendritic atrophy may be related to mental retardation. On the other hand, immunohistochem‐istry on proteins, whose genes are located on chromosome 21, revealed that c‐temiinal protein of beta‐amyloid appears in neurons of DS, S‐100‐positive glia increases in the hippocampus of neonates and adults, and membrane protein OK‐2 is expressed earlier and is more widespread in the DS brains. The overexpression and early appearance of gene products in DS brains may be related to the pathogenesis of or predisposition to mental disorders or to dendritic hypogenesis.
