Stroke 1: definition, burden, risk factors and diagnosis

The field of stroke has benefitted from many advances in recent decades, in particular, improved imaging techniques. This, coupled with better knowledge of brain function among professionals and greater awareness of stroke signs and symptoms among the general public, leads to the earlier identification, diagnosis, and treatment – which are key as stroke is a medical emergency. However, more needs to be done to reduce the personal and societal burden of stroke. This article – the first of a five-part series on stroke – discusses definitions, epidemiology, risk factors and diagnosis to help nurses gain an in-depth understanding of this complex condition.
