Overview
Historical Perspective
- Hippocrates (460 to 370 BC) was first to describe the phenomenon of sudden paralysis.
- Apoplexy, from the Greek word meaning "struck down with violence,” first appeared in Hippocratic writings to describe this phenomenon.[1]
- The word stroke was used as a synonym for apoplectic seizure as early as 1599,[2] and is a fairly literal translation of the Greek term.
- In 1658, in his Apoplexia, Johann Jacob Wepfer (1620–1695) identified the cause of hemorrhagic stroke when he suggested that people who had died of apoplexy had bleeding in their brains.[1]
- Wepfer also identified the main arteries supplying the brain, the vertebral and carotid arteries, and identified the cause of ischemic stroke when he suggested that apoplexy might be caused by a blockage to those vessels.

Epidemiology & Demographics
Stroke in USA
- Stroke is a leading cause of serious long-term disability
- In USA, the incidence and mortality rates of stroke has significantly decreased compared to previous years.
- From year 2003 to 2013, the mortality rates due to stroke declined by 18.5%.[3]
- In 2013, stroke became the fifth leading cause of death.
- The case fatality rate of stroke is estimated to be 41.7 deaths per 100, 000 population[3]
- The incidence of new (610, 000) or recurrent stroke (185, 000) is estimated to be 795000 people annually or 250 cases per 100, 000.[3]
- It is estimated that one incidence of stroke happens every 4 sec with death occuring every 4 min.[3]
- About 87% of all strokes are ischemic strokes[4]
- Stroke costs the United States an estimated $34 billion each year[4]
Worldwide
- According to WHO, the incidence of stroke is estimated to be 15 million people annually, worldwide.[5].
- Out of these, 5 million die and 5 million are left permanently disbaled.[5].
Age
- Stroke can occur in all age groups. However, the incidence of stroke is less among individuals age less than 40 years of age and the risk increases with increasing age. [4]
- According to WHO, stroke also occurs in about 8% of children with sickle cell disease.[5].
- In 2009, 34% of people hospitalized for stroke were younger than 65 years[4]
- The incidence of stroke in people aged 18 to 50 years is estimated to be approximately 10%. [3]
The rate of decline in mortality rates of stroke in different age groups is as follows:[3]
- >65 years of age: from 534.1 to 245.2 per 100,000
- 45-65 years of age: from 43.5 to 20.2 per 100,000
- 18 to 44 years of age: from from 3.7 to 2.0 per 100,000
Gender
There is increased incidence of stroke in men as compared to women.
Race
- The risk of incidence of first stroke is twice in african american population as compared to whites with increased mortality rates.[4]
- Hispanics’ risk for stroke falls between that of whites and blacks [4]
Geographical distribution
- There is increased incidence and mortality rates of stroke in developing countries as compared to developed countries due to low socio economic status and heath facilites.
- In USA, the highest death rates from stroke are in the southeastern United States.[4]
