About 80% of strokes are ischemic caused by the interruption of blood flow to the brain due to a blood clot.
About 20% of strokes are hemorrhagic caused by uncontrolled bleeding in the brain.
Stroke is the third leading cause of death in Canada. Six percent of all deaths in Canada are due to stroke (Statistics Canada, 2012).
Each year, over 14,000 Canadians die from stroke (Statistics Canada, 2012).
Each year, more women than men die from stroke (Statistics Canada, 2012).
There are estimated 50,000 strokes in Canada each year. That’s one stroke every 10 minutes (Hakim, Silver, & Hodgson, 1998).
Each year 200 to 300 Canadian children will experience a perinatal stroke (Canadian Stroke Network [CSN], 2011a).
About 315,000 Canadians are living with the effects of stroke (PHAC, 2011c).
For every minute delay in treating a stroke, the average patient loses 1.9 million brain cells, 13.8 billion synapses, and 12 km of axonal fibres (Saver, 2006).
Each hour in which treatment does not occur, the brain loses as many neurons as it does in almost 3.6 years of normal aging (Saver, 2006).
Stroke costs the Canadian economy $3.6 billion a year in physician services, hospital costs, lost wages, and decreased productivity (2000 statistic) (PHAC, 2009).
Every year, patients with stroke spend more than 639,000 days in acute care in Canadian hospitals and 4.5 million days in residential care facilities (CSN, 2011b).
Each year, about 15,000 people in Canada experience a TIA. Many more go unreported (Field, Green, Roy, Pedersen, & Hill, 2004).
The risk of recurrent stroke after a TIA is 10 to 20 percent within 90 days (CSN, 2011b).
People who have had a TIA are five times more likely to have a stroke over the next two years than the general population (CSN, 2011b).
