4 Influence Diagram

Influence Diagrams can be used as a Practical Clinical Guide to diagnose
Alzheimer and to determine in a normative way which is the most appropriate
action policy to take even for cases where it is not as evident and the doctor's
clinical judgement cannot provide a better solution. They could also contribute
to the application of more recent research studies, even explicitly and systemat-
ically combining different experts' opinions and the experimental data that are
obtained. It should be borne in mind that in all the research process computer
tools are being updated and upgraded and they are easily extensible For that
reason, we have wanted to refer to the Influence Diagrams as a fundamental
component for this research.
