Considering the growing evidence that we can prevent some dementias by preventing stroke beginning now, the World Stroke Organisation has launched a Proclamation calling for a joint prevention of stroke and potentially preventable dementias.

Download Stroke and Potentially Preventable Dementias Proclamation

Stroke and dementia are among the leading causes of disability and impairment of quality of life in old age. Vascular diseases are the second most common cause of dementia after Alzheimer's disease, and often contribute to the development of primary neurodegenerative dementias. While therapeutic breakthroughs in the neurodegenerative causes of dementia are still pending, improvements in vascular prevention and stroke treatment offer new and effective approaches to the prevention of dementia.

Concomitant with the implementation of a successful stroke strategy, the incidence of stroke declined by 32% and that of dementia of 7% over a 12 year period1. Since stroke doubles the chances of developing dementia and is in principle, 90% preventable2 we can begin preventing stroke and some dementias now. Multiple life interventions improve cognition, even APoE4 positive individuals3 and treating atrial fibrillation with anticoagulants can reduce the risk of dementia by 48%4.

A meeting addressing this evidence in depth and outlining the actionable conclusions will take place in Berlin, Germany on Saturday, October 13, 2018 as a satellite. At the World Health Summit will be a session presenting the main conclusions:
