Dementia in ICD-11 Beta Version

The ICD-11 Beta version browser is available at the WHO website as discussed in a previous post.

While this is not the final version, it is interesting to see how the classification is structured. I had a look at the classification of Dementia. As in ICD-10, Dementia is classified in both ‘Mental and Behavioural Disorders’* and ‘Disorders of the Nervous System’.

In ICD-10, Frontotemporal Dementia is located separately under the older classification of Pick’s Disease but also under circumscribed brain atrophy. In the beta version of ICD-11, Frontotemporal Dementia is classified under ‘Disorders of the Nervous System’ with categories including behavioural variant Frontotemporal Dementia and Frontotemporal Dementia with a recognised genetic mutation.

In ICD-10, Lewy Body Dementia is located under other specified degenerative diseases of the nervous system. In the beta version of ICD-11, Lewy Body Dementia is classified under ‘Disorders of the Nervous System’ as a distinct diagnostic entity.

The beta version of ICD-11 also includes (but is not limited to) Dementia resulting from nutritional deficiencies (e.g. vitamin deficiency), metabolic causes, infections and neurological disorders).

As this is the beta version, it is not necessarily the final version of ICD-11 but there is a considerable expansion in the causes of Dementia that facilitates a more precise description within the ICD terminology.

* In the ICD-11 beta browser this is listed as ‘mental, behavioural and neurodevelopmental disorders’.

This is the definition of the Health Information Exchange that I use (Hersh et al, 2015)

‘Health information exchange (HIE), the electronic sharing of clinical information across the boundaries of health care organizations‘
