What causes a Stroke? | Definition,Classification & Causes of Stroke #stroke
Heart disease: This includes conditions such as atrial fibrillation, heart attack, and coronary artery disease. These conditions can lead to blood clots that travel to the brain and cause a stroke.
Diabetes: High blood sugar levels can damage blood vessels and increase the risk of stroke.
Stroke risk factors: This includes smoking, excess alcohol consumption, and a sedentary lifestyle.
Hemorrhagic stroke occurs when a blood vessel in the brain ruptures, causing bleeding into the brain tissue. This bleeding can put pressure on the brain and damage brain cells. Hemorrhagic strokes are less common than ischemic strokes, accounting for about 13% of all strokes. They are more likely to occur in people who have high blood pressure, aneurysms (weak spots in blood vessels), or blood clotting disorders.
Other causes of stroke
In addition to the main causes mentioned above, there are a few other factors that can increase the risk of stroke. These include:
A history of stroke or other brain attack
Age: The risk of stroke increases with age.
Sex: Men are more likely to have a stroke than women, but women are more likely to die from a stroke.
Race and ethnicity: African Americans and Hispanics are more likely to have a stroke than white Americans.
Genetics: Some people are more genetically predisposed to stroke than others.
If you think you or someone you know may be having a stroke, it is important to call 911 immediately. Early diagnosis and treatment can improve the chances of a good recovery.
