In 2011, a number of studies shed further light on the understanding of stroke etiologies and mechanism. Regarding eating habit and a risk of stroke, three studies from Swedish cohort showed independent relations of chocolate, red meat, and coffee consumption with a risk of stroke. In relation to biomarkers, plasma tissue Kallikrein and resistin levels have been shown to be associated with a risk of stroke. In addition, with regard to infection and stroke, one study reported an increasing incidence of HIV infection in stroke patients and another study demonstrated that new-onset atrial fibrillation among patients with severe sepsis is associated with an increased risk of stroke. Finally, European consortium of cervical artery dissection reported risk factors for cervical artery dissection and differences between carotid and verterbral artery dissections.
