Stroke Facts in Developed Countries
- #1 cause of disability
- #2 cause of dementia
- #3 cause of death
- Major cause of epilepsy, falls and depression 7
A stroke is caused by either a sudden reduction in the blood supply to the brain or by a hemorrhage 10. Most strokes (85%) are ischaemic (caused by thrombosis or embolisms) and the rest (15%) are haemorrhagic (caused mainly by rupture of blood vessel or aneurysm). Eight to twelve per cent of ischaemic strokes and 37% to 38% of haemorrhagic strokes result in death within 30 days. Hemorrhagic strokes are less common but they are responsible for about 40 percent of all stroke deaths 11.
Stroke is the leading cause of disability among adults in the U.S. An estimated 6.8 million (2.8%) of people in the United States are living after having had a stroke, including 3.8 million women and 3 million men 16. Stroke is the second leading cause of disability in Europe after ischaemic heart disease (I HD) and is the sixth leading cause worldwide 12 13 14.Stroke is the second single most common cause of death in Europe: accounting for almost 1.1 million deaths each year 15.

Cost of stroke in the US:
2007 AHA ESTIMATES:
- Direct and indirect costs = $40 billion
- Mean lifetime cost = $140,048
- Inpatient hospital costs for an acute stroke event account for 70% of first-year post stroke costs.
- Estimates of total stroke cost between 2005-2050, in US dollars is projected to be $1.52 trillion for non-Hispanic whites, $313 billion for Hispanics, and $379 billion for Blacks
- Loss earnings is expected to be the highest cost contributor in eachrace/ethnic group 16.
The estimated cost of haemorrhagic stroke in Europe in 2010 was approximately € 8.3 billion 17.
According to the WHO, estimates the number of stroke events in EU countries, Iceland, Norway, and Switzerland is likely to increase from 1.1 million per year in 2000 to more than 1.5 million per year in 2025 solely because of the demographic changes 18.
The World Health Organization (WHO) predicts that disability-adjusted life years (DALYs) lost to stroke (a measure of the burden of disease) will rise from 38 million in 1990 to 61 million in 2020 19 20 21.
If these trends in stroke incidence, mortality, and DALYs continue, by 2030 there will be almost 12 million stroke deaths, 70 million stroke survivors, and more than 200 million DALYs lost globally 22 15. Between 2012 and 2030, total direct medical stroke-related costs are projected to triple, from $71.6 billion to $184.1 billion, with the majority of the projected increase in costs arising from those 65 to 79 years of age 23 16.
SDH can occur in about one third of people with a severe head injury 24.
Subdural haematomas occur not only in patients with severe head injury but also in patients with moderate head injuries, particularly those who are elderly or who are receiving anticoagulants. Subdural haematoma may also be spontaneous or caused by a procedure, such as a lumbar puncture. Rates of mortality and morbidity can be high, even with the best medical and neurosurgical care.
The incidence of chronic SDH is rising; SDH is projected to become the most common cranial neurosurgical condition among adults by the year 2030. Thus by 2030, chronic SDH drainage may be the most commonly performed neurosurgical procedure 25.
For UK, admissions for traumatic SDH increased 154% from 1993 to 2006 26, average costs increased 67% to $47,315 per admission 27 and national cost increased from $1.0 to $1.6 billion 28.
