CRSN Prevention

Stroke prevention encompasses risk factor reduction, both at a population and individual level. Implementing optimal stroke prevention strategies throughout the whole continuum of care has the potential to reduce the incidence of stroke by as much as 80%. (Rothwell, P.M. et al. (2007)

Primary prevention of stroke includes lifestyle modifications and measures to control blood pressure, cholesterol levels, diabetes mellitus, and atrial fibrillation. Lowering blood pressure in patients with hypertension prevents both hemorrhagic and ischemic stroke (relative risk reduction, 35 to 45 percent).

Secondary Prevention:

Secondary Prevention of stroke is an individually based, clinical approach to reducing the risk of events in persons who are experiencing symptoms that place them at high risk of a stroke or have already experienced a transient ischemic attack (TIA) or mild non-disabling stroke. Prevention strategies may include medication, surgery and support in making changes to lifestyle.
