Common themes of mood congruent delusions include guilt, persecution, punishment, personal inadequacy, or disease. Half of patients experience more than one kind of delusion. Delusions occur without hallucinations in about one-half to two-thirds of patients with psychotic depression.
Persecutory delusion
This is the most common form of delusional disorder. In this form, the affected person fears they are being stalked, spied upon, obstructed, poisoned, conspired against or harassed by other individuals or an organization.
Some people who have severe depression may also experience hallucinations and delusional thinking, the symptoms of psychosis. Depression with psychosis is known as psychotic depression.
The type of delusion showing the strongest association with diagnosis was delusion of guilt, to the extent that it emerged as almost pathognomonic of psychotic depressive conditions.
Types of delusions include persecutory, erotomanic , grandiose , jealous, somatic, and mixed/unspecific.
Although psychotic depression itself cannot evolve into schizophrenia, when severe depression is untreated or undertreated, it's possible for the resulting distress and side effects to trigger an underlying psychotic disorder, such as schizoaffective disorder.
Hearing sounds, such as music, footsteps, windows or doors banging. Hearing voices when no one has spoken (the most common type of hallucination). These voices may be positive, negative, or neutral. They may command someone to do something that may cause harm to themselves or others.

One of the most notable differences between the two disorders is that while in the case of schizophrenia, labeling as mental illness primarily affects respondents' emotional reactions negatively, in the case of major depression a positive effect prevails.
Medications often used to treat depression or ADD can certainly cause manic episodes, including severe manic episodes with psychotic symptoms like hallucinations or delusions. Those episodes can come on quite suddenly.
Environmental/psychological: Evidence suggests that stress can trigger delusional disorder. Alcohol and drug abuse also might contribute to it. People who tend to be isolated, such as immigrants or those with poor sight and hearing, appear to be more likely to have delusional disorder.
