The World Health Organization (WHO) will reclassify stroke and vascular dementia as diseases of the nervous system in the next ICD (ICD-11), due to launch in 2018. 

In the current ICD (ICD-10) and since 1955, stroke has been classified as a disease of the circulatory system.

What is the ICD?

The international classification of diseases (ICD) is the standard diagnostic tool used for clinical purposes, in health management and in the analyses of the general health situation of populations worldwide.

It is used to monitor how often someone gets a disease or other health problem (known as the 'incidence' of the disease) and how many people in that population are living with the disease (known as the 'prevalence' of the disease).

It can provide an overall picture of the general health situation of populations, including countries.

The ICD is used by a range of professionals which include physicians, nurses, researchers, policymakers and patient organisations.

What do the World Stroke Organization say?

The World Stroke Organization (WSO) welcomes the WHO decision on the reclassification of stroke in the ICD-11. To find out more, visit the World Stroke Organization blog.
