ICD-11 code : 6A24;
Preferred Label : Delusional disorder;
ICD-11 definition : Delusional disorder is characterized by the development of a delusion or set of related
delusions that persist for at least 3 months (usually much longer), which occur in
the absence of a Depressive, Manic, or Mixed mood episode. Other characteristic symptoms
of Schizophrenia (e.g. persistent auditory hallucinations, disorganized thinking,
negative symptoms) are not present, although various forms of perceptual disturbances
(e.g., hallucinations, illusions, misidentifications of persons) thematically related
to the delusion are still consistent with the diagnosis. Apart from actions and attitudes
directly related to the delusion or delusional system, affect, speech, and behavior
are typically unaffected. The symptoms are not a manifestation of another disorder
or disease that is not classified under Mental, behavioural or neurodevelopmental
disorders (e.g., a brain tumor) and are not due to the effect of a substance or medication
on the central nervous system (e.g., corticosteroids), including withdrawal effects
(e.g., alcohol withdrawal).;
