Transcript of Stroke
The organ that a stroke affects is the right side and left side of the brain. One side of the brain controls the opposite side of the body. For example, if the stroke were to occur on the right side of the brain, the left side of the body would be affected. A stroke can also affect the brain stem. If this occurs, both sides of the brain will be affected. When a person has this type of stroke, they may be left a locked state . A locked state is when a person can't speak or move below the neck
Is it genetic?
It can be, your stroke risk is greater if a parent, grandparent, or siblings have had a stroke. It has a long been known however that genetics may contribute up to 50% of an individual's risk of developing a stroke in the future. Genes play a role in the development of risk factors that can lead to a stroke, such as high blood pressure, heart disease, diabetes, and vascular conditions. An increased risk for stroke within a family may also be due to common behavioral factors, such as poor eating habits.
Symptoms of a Stroke
sudden numbness, tingling, weakness, or loss of movement in your face, arm, or leg, especially on only 1 side of your body
sudden vision changes
sudden trouble speaking
sudden confusion or trouble understanding simple statements
sudden problems with walking or balance
sudden or severe headaches that are different from past headaches
symptoms can vary depending on the stroke and also depends on where the stroke occurs and how bad it is
A stroke is a sudden loss of brain function that is caused by the interruption of blood flow to the brain (ischemic stroke) or the rupture of blood vessels in the brain (hemorrhagic stroke). The interruption of blood flow or the rupture of blood vessels causes brain cells (neurons) in the affected area to die.
Is it fatal?
stroke is the third leading cause of death in Canada. 6% of all deaths in Canada are due to a stroke (Statistics Canada 2012)
a stroke can be fatal or leave someone permanently disabled
one quarter of strokes are fatal
each year 14 000 Canadians die from a stroke (Statistics Canada 2012)
each year, more women than men die from stroke
not all strokes are fatal
strokes in the brainstem are the most dangerous
What is the treatment?
What is the impact of a stroke on everyday life.
How to Prevent and Reduce the Risk
Weakness on 1 side of the body
this can cause problems with walking or problems using hands and arms
range from having difficulty finding the right words to say to being completely unable to talk
this can include complications with double vision or losing half the field of vision
Difficulties with mental processes
these can include difficulty in learning, concentrating, and long term memory
recovering patients may laugh or cry at times for no apparent reason
tPA (tissue plasminogen activator)
tPA is a drug that can stop a stroke caused by breaking up the clot (isschemic stroke). It must be given within 3 hours of the onset of symptoms.
Surgery may be required damage after a stroke or to prevent a stroke from occurring. Surgery may be done to remove blood that has pooled in the brain after a hemorrhagic stroke to repair broken blood vessels, or to remove plaque from inside the carotid artery
Some people may benefit from treatments through a catheter (a thin flexible tube) that is put into the blood vessels or the brain. Catheter based products are developed to remove plaque buildup from arteries and to treat aneurysms.
Rehabilitation helps stroke survivors relearn skills that are lost when part of the brain is damaged. For example, these skills can include coordinating leg movements in order to walk or carrying out the steps involved in any complex activities. Rehabilitation also teaches survivors new ways of performing tasks to avoid any remaining disabilities. Individuals may need to learn how to bathe and dress using only one hand or how to communicate effectively when their ability to use language has been compromised.
To prevent a stroke...
know your blood pressure
control your weight
eat a healthy diet
know you cholesterol levels
control your alcohol intake
manage your diabetes
treat circulation problems
Can you live with a stroke?

It is possible to survive a stroke or die from it. A stroke survivor may be left paralyzed, have speech difficulties, and vision problems. In general, the less damage there is to the brain tissue, the less disability results and greater the chances of a successful recovery. About half the people who have a stroke, will have some long term problems with talking, understanding, and decision making.
