Summary
A clinical and pathological study of juvenile amaurotic idiocy is presented with an illustrative case report. The case described had the classical criteria of retinitis pigmentosa, progressive mental deterioration and a convulsive component as evidenced by the electro-encephalogram.
Pathological and histochemical studies indicate pigmentary and neuronal changes similar to those associated with alterations of the senile brain. The neuronal deposits are of a lipochrome nature, similar to, if not identical with, lipofuscin. The concept of a precocious senility is advanced to stimulate comparative studies with the dementias of senility.
It is pointed out that, regardless of the etiology—either of lipoid disorder, congenital deficiency of the neuro-ectodermal germ layer, or arrested physiological maturity of the nerve cells—a final clinicopathological state of senility is reached in the nervous system of juvenile amaurotic family idiocy.
