People with depression can experience hallucinations. Depression is an affective disorder, and the main symptoms include low mood, lack of pleasure, loss of interest, sleep disturbance, loss of appetite, self-blame, self-guilt, and suicide. Patients with severe depression may also experience psychiatric symptoms such as hallucinations, delusions, thought insertion, and thought broadcasting, etc. In addition to antidepressant treatment, these patients need antipsychotic medications to control psychiatric symptoms. These patients also need to identify whether it is depression with psychotic symptoms or schizoaffective disorder. Patients with depression with psychotic symptoms first meet the diagnostic criteria for depression and then develop psychotic symptoms after a period of time; schizoaffective disorder meets both the diagnostic criteria for schizophrenia and depression, and the two types of symptoms appear a few days apart or at the same time.
