The Lancet Neurology: May 16, 2007

Editor Helen Frankish discusses highlights from the June issue: research from the University of Oxford about the incidence of haemorragic stroke; while incidence has decreased in younger age groups over the past two decades, inclusion of data from people aged over 75 years shows how overall incidence has remained the same, underlining the need for the inclusion of older people in stroke research. Also discussed is the comprehensive review on migraine and this month's editorial about stem-cell research in the USA.
