What would doctors recommend as treatment for schizoaffective disorder?

Depends on symptoms: It depends on what symptoms were being experienced. If depression predominates then antidepressants, if thought disorder is present then anti psychotic or mood stabilizer. Anxiety symptoms may also need to be treated.

Schizoaffective: The patient will need a full psychiatric evaluation and medication, most notable antipsychotics and mood stabilizers, as schizoaffective disorder is a combination of schizophrenia and bipolar disorder (formerly known as manic depression). A referral to a reputable psychotherapist is also indicated. Meds and therapy are typically the optimal combination.
