Alzheimer disease, Pick disease and senile dementia are all characteri
zed by similar morphological changes, both macroscopic and microscopic
, and similar psychiatric symptoms. All three should, therefore, be vi
ewed as aspects of one disease, which is termed Alzheimer-type dementi
a. Nothing contradicts the view that immune complexes take part in the
etiology of Alzheimer-type dementia. There are various types of immun
e complexes and so their points of action in the organism may vary. Th
ere might be two main means of preventing Azheimer-type dementia: the
first could be named the serological (basic) and the second relying on
pharmacotherapy (additional). Pharmacological prevention of disease m
ight be aided by the use of parasympathomimetic drugs, e.g. pilocarpin
