The main points of a workshop on the place of clinical trials in the m
emory clinics in France are reproduced schematically. The efficiency o
f these centres has been tested at the time of the numerous clinical t
rials performed in France on Alzheimer's disease. In parallel, several
difficulties have been pointed out: inhomogeneity of the technical ap
proaches, official role of psychologists in the hospital teams, integr
ation of clinical research to individual care. A particular effort sho
uld be oriented towards specific research on the different types of de
mentia, on early stages, on information for both media and authorities
as well as on specific technical and methodological problems.
