Core diagnostic criteria, specifiers, differential considerations, and documentation support in one open, scan-friendly view.
All criteria are shown. No expand controls or hidden sections.
Core criterion A
≥1 month of ≥1 delusion(s)
Core criterion B
Schizophrenia Criterion A never met; hallucinations not prominent or related to delusional theme
Core criterion C
Functioning not markedly impaired; behaviour not obviously odd apart from delusion
Core criterion D
No manic/major depressive episode; or mood episodes brief relative to delusion duration
Core criterion E
Not attributable to substances or another medical condition
Consistent with [Delusional Disorder] [specifier(s)]. For at least one month, there have been one or more delusions; persecutory delusions; grandiose delusions; jealous delusions; erotomanic delusions; somatic delusions; mixed delusional themes, occurring in the absence of prominent hallucinations, with hallucinations, if present, being mild and directly related to the delusional theme. Apart from the delusional system, functioning is relatively preserved, and behaviour is not markedly disorganised or odd outside of delusion-related areas. The presentation is further characterised by stable, fixed beliefs held despite clear contrary evidence, with no sustained mood episodes. These symptoms have resulted in clinically significant distress or impairment, and the picture is not better explained by schizophrenia, schizoaffective disorder, mood disorders with psychotic features, substance/medication effects, or a medical condition.
