Stroke is the leading cause of adult disability, and the third leading cause of death.
A stroke is a sudden loss of brain function caused by a blockage in a blood vessel (ischemic stroke) or a rupture in a blood vessel (hemorrhagic stroke). The interruption in blood flow prevents oxygen from reaching the brain, causing cells to die.
The effects of a stroke depend on which cells are damaged. One-third to two-thirds of stroke survivors need rehabilitation for a loss of physical or cognitive function or difficulty with communication skills. Stroke is the leading cause of adult disability, and the third leading cause of death.
A stroke is a medical emergency. If you think someone may be having a stroke, call 9-1-1 right away. Acting quickly could save the person’s life and prevent lasting disability.
Signs and symptoms of a stroke for both men and women include:
- Weakness on one side of the body, or numbness or tingling in the face, arm or leg
- Trouble speaking (slurring or strange speech ) or understanding what others say
- Vision problems in one or both eyes , or double vision
- Headache that is sudden, severe or unusual
- Dizziness, coordination or balance problems
Risk factors for stroke
Stroke and heart disease share many of the same risk factors. There are two types of risk factors: those we can’t change (non-modifiable) and those we can change (modifiable). According to Heart & Stroke, eight out of 10 cases of premature heart disease and stroke are preventable with healthy lifestyle behaviours.
Non-modifiable risk factors
- Age: The risk of both heart disease and stroke increases with age. Two-thirds of strokes happen in people over age 65.
Modifiable risk factors
- Smoking: Smoking (or long-term exposure to second-hand smoke) significantly increases the risk of heart disease and stroke
- Being overweight or obese: Carrying too much weight raises your risk of several diseases, including heart disease and stroke.
- Lack of exercise: You can reduce your risk of heart disease and stroke by exercising regularly. (Learn more about Canada’s physical activity guidelines.)
- Eating an unhealthy diet: Aim for a diet low in saturated fat, trans fats, sodium and cholesterol, and high in fruits and vegetables. (Learn about healthy eating with Canada’s food guides.)
