Background
• Stroke: major public health issue
– Frequent – Important killer– Often leave patients with residual disability– High risk of delayed complications– Most are preventable– Many are treatable– Leads to important direct and indirect costs

• Aim of the synergium : – To devise and prioritise new ways of accelerating progress
in reducing the risks, effects and consequences of stroke
• Method : – Preliminary work was performed by 7 working groups of stroke
leaders followed by a synergium (a forum for working synergistically together) with approximately 100 additional participants.
– The resulting draft document had further input from contributors outside the synergium
Priorities for the next decade

Brugge. Nov. 28th, 2013
• Basic science, drug development and technology– There is a need to develop
• New systems of working together to break down the prevalent “silo” mentality
• New models of vertically integrated basic, clinical, and epidemiological disciplines
• Efficient methods of identifying other relevant areas of science.
Priorities for the next decade
![Page 38: Stroke in Europe](https://reader035.vdocuments.us/reader035/viewer/2022062222/56816600550346895dd9308e/html5/thumbnails/38.jpg)
Brugge. Nov. 28th, 2013
• Stroke prevention– There is a need to develop
• Establish a global chronic disease prevention initiative with stroke as a major focus.
• Recognize not only abrupt clinical stroke, but subtle subclinical stroke, the commonest type of cerebrovascular disease, leading to impairments of executive function.
• Develop, implement and evaluate a population approach for stroke prevention.
• Develop public health communication strategies using traditional and novel (eg, social media/marketing) techniques.
Priorities for the next decade

Brugge. Nov. 28th, 2013
• Acute Stroke management– There is a need to continue the establishment of
• Stroke centers,• Regional systems of emergency stroke care• Telestroke networks.
Priorities for the next decade

Brugge. Nov. 28th, 2013
• Brain recovery and rehabilitation– There is a need to:
• Translate best neuroscience, including animal and human studies, into poststroke recovery research and clinical care.
• Standardise poststroke rehabilitation based on best evidence. • Develop consensus on, then implementation of, standardized
clinical and surrogate assessments. • Carry out rigorous clinical research to advance stroke recovery.
Priorities for the next decade
![Page 41: Stroke in Europe](https://reader035.vdocuments.us/reader035/viewer/2022062222/56816600550346895dd9308e/html5/thumbnails/41.jpg)
Brugge. Nov. 28th, 2013
• Into the 21st century : web, technology, communication– There is a need to:
• Work toward global unrestricted access to stroke-related information.• Build centralised electronic archives and registries
• Foster cooperation amongst stakeholders to enhance stroke care:– large stroke organisations, nongovernmental organisations, governments,
patient organisations and industry• Educate professionals, patients, public, and policy makers
Priorities for the next decade
