Colleagues are reviewing content relating to intoxication delirium under 191492000 |Delirium caused by drug (disorder)| e.g. 18653004 |Alcohol intoxication delirium (disorder)| and 8635005 |Alcohol withdrawal delirium (disorder)| which has raised some questions that need clinical input.
Delirium in SNOMED is classified as a descendant of 111479008 |Organic mental disorder (disorder)| which in turn is a subtype of 74732009 |Mental disorder (disorder)| and 81308009 |Disorder of brain (disorder)|.
Descendants of Organic Mental Disorder include:
52448006 |Dementia (disorder)|
2776000 |Delirium (disorder)|
286933003 |Confusional state (disorder)|
Looking at ICD-11 and DSM-V delirium and dementia are now subtypes of neurocognitive disorders.
Questions:
- Is the current concept Organic mental disorder still clinically useful?
- Should the delirium and dementia concepts be moved to be subtypes 709073001 |Neurocognitive disorder (disorder)| ?
