Creutzfeldt-jacob disease: a comparative light-microscopic, histochemical and electron-microscopic study.

The morphological and histochemical findings in a brain biopsy of a case of Creutzfeldt-Jacob disease are compared. The histochemical changes in the cytoplasm of the neurons precede the morphological alterations found with the electron microscope. In this way the neuronal enzymatic failure can explain the clinical picture of this disease.
