High blood pressure is the main trigger for strokes. However, there are other risk factors that are important to be aware of.
A cerebral vascular accident ( stroke ) occurs when blood flows to part of the brain it stops .
If blood flow is interrupted for more than a few seconds, the brain cannot receive nutrients or oxygen. brain cells can die, causing permanent damage .
A stroke occurs when a blood vessel in the brain ruptures , causing bleeding inside the head . Sometimes called a “brain attack.”
According to the United States National Library of Medicine, there are two types of stroke:
1. Ischemic stroke
This happens when a blood vessel supplying blood to the brain is blocked by a blood clot . This can happen in two ways.
In the first place, a clot can form in an already very narrow artery . It’s called thrombotic stroke .
SO, A clot may break away from blood vessels in the brain or somewhere in the body and travel to the brain. . It’s called cerebral embolism or embolic stroke .
Ischemic strokes can also be caused by a sticky substance called plaque that can block the arteries.
2. Hemorrhagic stroke
This happens when a blood vessel in part of the brain weakens and breaks, causing blood to leak into the brain .
Some people have abnormalities in the blood vessels of the brain that make this group of strokes more likely.
These faults may include:
Aneurysm : a weak area in the wall of a blood vessel that causes a bubble to form outside the vessel.
arteriovenous malformation : abnormal connection between arteries and veins.
Cerebral amyloid angiopathy : condition in which amyloid proteins accumulate on the walls of the arteries of the brain.
What factors can cause a stroke?
High blood pressure is the main risk factor for stroke . However, there are other important risk elements to be aware of:
- Irregular heart rate call atrial fibrillation
- Family history of illness
- Be a man
- High cholesterol
- Increasing age, especially after 55 years
- Ethnicity (black people are more likely to die of stroke)
- People with heart disease or poor circulation in the legs caused by narrowing of the arteries
- Excessive consumption of alcohol
- Drug use
- High-fat diets
- Lack of exercise
- Women taking birth control pills (especially those who smoke and are over 35)
- Women on hormone replacement therapy
What is a person’s life expectancy after a stroke?
A person’s prognosis after a stroke depends on several factors. :
- Type of stroke
- Amount of damaged brain tissue
- Body functions affected
- How quickly the treatment was administered
Problems with movement, thinking, and speech often begin to improve in the days or weeks after the stroke.
According to information from the United States National Library of Medicine, More than half of people who have had a stroke are able to function and live at home . Other people are not able to take care of themselves without help.
If treatment with thrombolytics is successful, stroke symptoms may disappear .
However, People often do not arrive at the hospital in time to receive these medications or are unable to take them due to illness. .
People who have had a stroke due to a blood clot (ischemic) have a better chance of survival that those who have a stroke due to bleeding in the brain (hemorrhagic).
