Schizoaffective disorders
Episodic disorders in which both affective and schizophrenic symptoms are
prominent but which do not justify a diagnosis of either schizophrenia or
depressive or manic episodes. Other conditions in which affective symptoms are
superimposed on a pre-existing schizophrenic illness, or co-exist or alternate with
persistent delusional disorders of other kinds, are classified under F20-F29.
Mood-incongruent psychotic symptoms in affective disorders do not justify a
diagnosis of schizoaffective disorder.

type.
