Well, these are the main risk factors for stroke:
The rates of obesity in the young population are really increasing fast (a frightening proportion of school children are now classed as clinically obese) and for the first time young people are developing weight-related type 2 diabetes. Both weight excess and diabetes are separate risk factors for stroke, so this may be a contributory factor.
Whilst figures showed an overall decrease in the incidence of stroke in the UK decade from 1999-2008 (connected to better identification of those at risk and prescribing of new and better drugs to prevent and treat stroke), it is still a major cause of death and disability and I think the huge increase in obesity in the young will only make things worse. The following stats are from the National Heart Forum:
Its important for the physios to get working on a stroke victim as soon as possible.
