Frailty in stroke.

Stroke is predominantly a condition of older age. So, it seems sensible that specialists working in stroke services should understand the primary clinical syndrome of ageing-frailty. Recent studies have highlighted the prevalence of frailty in stroke and its associated poor outcomes, yet frailty does not feature prominently in stroke research, practice or policy. Frailty-informed stroke care may differ from the interventional management that dominates contemporary practice. However, this is not therapeutic nihilism. A person-centred approach ensures that every care decision is appropriate and based on a shared understanding of the person's goals and likely prognosis. We present a primer on frailty in stroke, describing definition(s), epidemiology and prognostic implications. We discuss the challenges surrounding assessment and management of frailty in stroke units and offer practical guidance suitable for the stroke clinician.
