Maintaining a healthy lifestyle can cut your risk for first-time stroke by 80%, according to new guidelines from the American Heart Association and the American Stroke Association.
As the US population ages and obesity increases, more strokes are occurring 795,000 a year, 77% of them first-time but deaths from stroke have decreased, experts say.
Genetic screening for stroke may be appropriate for some at-risk patients, but not for the general public.
Treating patients with a blocked neck artery (carotid artery) with a stent or surgery (endarterectomy) should be decided on a case-by-case basis.
Screening for narrowing of the neck arteries is not recommended.
Aspirin is advised only for people at high risk of stroke for whom the reduction in stroke risk outweighs the bleeding risk of aspirin.
