Stroke is also known as cardiovascular accident. It involves loss of brain functions due to a disturbance in the supply of blood to the brain. It may be caused by a blockage in the artery supplying blood to the brain or by bleeding disorders that involves the brain.
How deadly is it? Surprisingly, stroke is the second leading cause of death around the world. 40% of the total people who get affected will experience severe to moderate impairments in body functions and will require special care while 15% may die shortly afterwards.
What are the risk factors?
- Smoking
- Gender – Stroke is more common in men than women. Although women account for more than 61 percent of deaths from stroke.
- Age – Your risk of experiencing stroke doubles if you are 55 years of age or above.
- High blood pressure and blood cholesterol levels – This is the second leading cause of stroke but it is controllable and can be treated.
- Diabetes – Persons with diabetes may also have high blood pressure and blood cholesterol levels. These will increase their risk of having stroke.
- Arrythmias or irregular heartbeat. In heart rhythm disorders, the upper chambers of the heart shake rapidly instead of beating regularly. This causes the blood to clot or pool. Blood clots can enter the bloodstream and can block the artery going to the brain.
What are the signs and symptoms?
- Sudden numbness of the face, arms and legs, weakness and partial or complete loss of voluntary movement
- Confusion or slurring of speech
- Blurring of vision
- Loss of balance when walking or standing, loss of coordination
- Severe headache with unknown cause
How is stroke treated?
A tissue plasminogen activator should be administered 4 to 6 hours after symptoms of stroke are detected. Blood thinners such as heparin and aspirin are given to dissolve clots. In severe cases, a surgical procedure may be indicated. These treatments can improve the outcome of stroke and prevents it from reoccurring.
How can we prevent it?
Prevention is centered at the underlying causes and risk factors such as maintaining a normal blood pressure and blood sugar level, lowering blood cholesterol levels and quitting smoking. Post-stroke patients are given blood thinners to prevent subsequent strokes.
