Causes of stroke
A stroke can be caused by a clot (blood clot) blocking an artery in the brain. Other causes include a ruptured cerebral artery, traumatic brain injury, or brain tumor.
Stroke Prevention
The risk factors leading to stroke and cardiovascular disease are similar. It is possible to significantly reduce the likelihood of a stroke by following the healthy lifestyle recommendations described above for the prevention of cardiovascular diseases.
Signs and symptoms of stroke
• Sudden weakness and/or numbness of the face,
arms or legs usually on one side.
• Difficulty or slurred language.
• Sudden severe headache.
• Dizziness or distress.
• Unconscious.
• Pupils of different sizes.
Transient cerebrovascular accident
Transient cerebrovascular accident is a temporary phenomenon resembling a stroke. Sometimes even this condition is called a “mini-stroke”. As with a stroke, a transient cerebrovascular accident causes a decrease in blood flow to the brain. The episode can last for one hour. This type of disturbance usually occurs in the morning. The patient should immediately seek medical help.
As in any emergency situation, follow basic first aid principles.
A stroke is an acute disorder of cerebral circulation, leading to damage to the brain tissue itself. This disease is the second most common killer of people worldwide, and in recent years the incidence of strokes has even exceeded the number of myocardial infarctions by 2.3 times. The consequences of a stroke are truly catastrophic. Up to 84.87% of patients die or remain disabled, and only 10.13% of patients fully recover.
A stroke occurs when the blood vessels supplying the brain become narrowed, blocked, or ruptured. Most strokes are ischemic - the artery is blocked by a blood clot or narrowed by atherosclerotic plaque. In a hemorrhagic stroke, a defective artery ruptures.
Symptoms of a stroke:
- Sudden numbness or weakness on one side of the body.
- Impaired speech, vision, and coordination of movements.
- Strong headache.
Diagnosis is based on magnetic resonance imaging and ultrasound examination of blood vessels. Treatment is aimed at restoring blood flow and rehabilitation.
For prevention, it is important to regularly measure blood pressure and lead a healthy lifestyle. Stroke can be prevented if risk factors are addressed early.
