Intelligence encompasses cognition. Cognition is the method by which people assimilate
and integrate knowledge, while intelligence is both the assimilation of knowledge as
well as the ability to apply such knowledge, i.e., the proficiency one has in a given area.

It's the emotions that are affecting cognition; if the emotions are not being cared for
properly, it's no wonder that cognition would be affected. Attention needs to be directed
to the medication prescriptions, in my view, or to psychotherapy.

A psychiatrist once described it to me this way: "your emotions get in the way of your intelligence". At the same time he said "you are an intelligent person". (I don't like to
say that, but it is being done only in an effort to try to separate by explanation the differences between cognition and intelligence.) The illness is not one of intelligence. That's a pretty solid statement of what bipolar illness is, excluding the fact that it is a dynamic illness, not a static one.

Get the emotions correctedl (which are affecting the way one sees things); then
the intelligence is going to act rather than the emotions. Cognition seems to me to
apply more to the way one sees things, not to the way one applies intelligence.

I really do not agree with the idea that bipolar illness is one of diseased intelligence
and have never been told that.

It may be that there is a disagreement on what "mood" means. I take it to mean
the emotions. Others may see it differently.
