ICD-11 code : 6A24;
Preferred Label : Delusional disorder;
ICD-11 definition : Delusional disorder is characterised by the development of a delusion or set of related
delusions, typically persisting for at least 3 months and often much longer, in the
absence of a Depressive, Manic, or Mixed mood episode. The delusions are variable
in content across individuals, but typically stable within individuals, although they
may evolve over time. Other characteristic symptoms of Schizophrenia (i.e. clear and
persistent hallucinations, negative symptoms, disorganised thinking, or experiences
of influence, passivity, or control) 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
medical condition (e.g., a brain tumour) 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).;
