Other features differentiate diseases with delusions as well. Delusions may be described as mood-congruent (the delusional content in keeping with the mood), typical of manic or depressive psychosis, or mood-incongruent (delusional content not in keeping with the mood) which are more typical of schizophrenia. Delusions of control, or passivity experiences (in which the individual has the experience of the mind or body being under the influence or control of some kind of external force or agency), are typical of schizophrenia. Examples of this include experiences of thought withdrawal, thought insertion, thought broadcasting, and somatic passivity. Schneiderian first rank symptoms are a set of delusions and hallucinations which have been said to be highly suggestive of a diagnosis of schizophrenia. Delusions of guilt, delusions of poverty, and nihilistic delusions (belief that one has no mind or is already dead) are typical of depressive psychoses.
