Which condition is not typically treated with antidepressants?

In the context of psychopharmacology, acute psychosis is generally not treated with antidepressants as a first-line approach. Acute psychosis is often associated with conditions like schizophrenia or severe mood disorders, where antipsychotic medications are the primary form of treatment. Antidepressants may not address the core symptoms of psychosis, such as delusions or hallucinations, which require the stabilizing effects of antipsychotics to manage effectively.

In contrast, the other conditions listed typically involve the use of antidepressants. Anxiety disorders often respond well to certain antidepressants, particularly selective serotonin reuptake inhibitors (SSRIs). Bipolar disorder may additionally necessitate mood stabilizers, but in its depressive phases, antidepressants can be employed cautiously due to the risk of inducing mania. Bulimia nervosa may also be treated with antidepressants, as they can help reduce binge-eating episodes and control associated symptoms of depression and anxiety.

Therefore, acute psychosis stands out as not being typically addressed with antidepressants, making it the correct choice.
