Antipsychotics are often used as mood stabilizers, and some of them are really very effective for that purpose. Many patients who have never had psychotic symptoms (patients with depression which has not responded to just an antidepressant, for instance) are finding that the addition of an "atypical" or newer antipsychotic can be helpful. This is an example of the problem with names in pharmacology. We call something an "antipsychotic" and then people feel that their doctor must be crazy because they aren't psychotic, but in fact the medication may be very useful for them.
