[Features of senile cerebral amyloidosis]

It is established, on the basis of the autopsy material of I. M. Sechenov First Moscow Medical Institute for 1983-1987 (517 patients who died at the age of 40-89 years), that senile cerebral amyloidosis (SCA) is a local form of senile amyloidosis which occurs in 4.4% persons over 60 years of age. At the autopsy SCA is revealed in 21.4% cases, but the examination of the brain for amyloid increases the percent up to 78.6. Amyloid deposits are observed as senile plaques in the vessels of pia mater, plexus chorioideus and intracerebral vessels. Genetic factors in the SCA development can not be excluded.
