One option for the DSM-5 would have been to remove the schizoaffective disorder category and to add affective mood symptoms is, mania, hypomania, mixed episode, or depression as a dimension to schizophrenia and schizophreniform disorder "or" to define a single category for the co-occurrence of psychosis and mood symptoms. This option was extensively debated but ultimately deemed to be premature in the absence of sufficient clinical and theoretical validating data justifying such a … reconceptualization. Additionally, there appeared to be no practical way to introduce affect mood dimensions covering the entire course of illness, that would capture the current concept of periods of psychosis related and unrelated to mood episodes.
