In brief: No, depends
If you are in the depths of depression, or spinning in a manic episode when your IQ is tested, you won't score as well as you ordinarily would.
That said, depression & bipolar patients tend to be brighter than average. Interesting question. Why do you ask?

In brief: Lower IQ
Absolutely. Cognitive functioning and intelligence testing can be negatively impacted by emotional disorders.

In brief: Probably not
Depression, or bipolar disorder, are illnesses.
Like any other illness, they can affect your ability to think or to process information. Iq is a relatively fixed quantity. So, it is likely that if you are, for example, depressed, you may test at a lower iq. But, once you get better, you would test at a level more reflective of your actual ability.

Completely disagree. IQ is very sensitive to changes in emotional functioning and it can depress scores.
