The origin and the pathological significance of the corpus amylaceum.
After the investigation of the CA in different diseases of the central nervous system it may be concluded that the causative factor can be effective in different situations. The chronic, mainly arteriopathic disorders associate with great amount of the CA predominantly, but they have no diagnostic significance.

The CA may be situated outside of the cells.
