A stroke that is caused by a blood clot is called an ischaemic stroke (is-key-mick).
A stroke occurs when the body stops supplying blood to the brain. Ischemic stroke is the most common type of stroke, and it develops due to a blockage in the arteries around the brain.
Types of Ischemic stroke:
Embolic stroke :
- This occurs when a blood clot, piece of plaque, or another object forms in a different part of the body and travels to the brain’s blood vessels.
Thrombotic stroke :
- This type of stroke occurs when a thrombus or clot forms inside a blood vessel in the brain.
An ischemic stroke occurs due to atherosclerosis, which causes fatty deposits and a buildup of cholesterol plaque in the blood vessels.
When too much plaque collects in one spot, it can block the blood flow to vital organs.
A blood clot may stick to a plaque buildup while passing through the blood vessels, which also creates a blockage.
The neck contains carotid arteries, which are blood vessels that supply blood to the brain. If plaque blocks a carotid artery (carotid artery disease), a stroke might occur.
Atherosclerosis is largely symptomless. Therefore, many people do not know they have atherosclerosis until they have a stroke or experience the other effects of blocked arteries near different organs, such as a heart attack.
Symptoms of Ischemic Stroke
Strokes can be life-threatening, so it is important to seek medical care immediately if symptoms appear.
Ischemic stroke symptoms often affect one side of the body and develop quickly.
Beyond F.A.S.T., a stroke may also cause the following symptoms to develop suddenly:
- difficulty walking
- falling without an identifiable cause
- a sudden inability to understand speech
- rapidly developing vision problems
- a severe headache without an apparent cause
Signs Of Stroke:
F = Face drooping: People may notice one side of the face drooping or feeling numb. Another person can check for this symptom by asking the person to smile or stick out their tongue.
If their smile is uneven, or their tongue moves to one side of the mouth instead of the middle, this could be a warning sign for ischemic stroke.
A = Arm weakness: Being unable to lift one arm or feeling weakness or numbness in one arm may suggest that an ischemic stroke is occurring.
S = Speech problems: These might include being unable to speak or repeat a sentence clearly.
T = Time to call : Contact emergency services immediately on nothing the other indicators of ischemic stroke.
Prevention of Ischemic Stroke:
Even people with risk factors or a history of stroke can take steps to improve cardiovascular health and reduce the risk of ischemic stroke.
The following measures can help prevent a stroke and improve overall health:
Having regular check-ups: High blood pressure and cholesterol do not have visible symptoms. Regular health tests are the only way to know if these are present. Blood tests and health checkups can help detect these problems early and allow for timely treatment.
Getting regular exercise: An active lifestyle reduces the risk of diabetes, high blood pressure, high cholesterol, and other conditions that increase the risk of ischemic stroke.
Following a heart-healthy diet: A diet should be low in “bad” fats, such as saturated and trans fats. People should also limit their sodium intake. Eating more fruits, vegetables, whole grains, healthful fats, and lean proteins can help them preserve cardiovascular health.
Managing body weight: If a person is overweight or has obesity, reaching a healthy body weight can bring down their risk for stroke.
Avoiding first-hand or secondary smoking: Smoking and inhaling smoke from others can cause damage to blood vessels and increase the risk of stroke-related health problems.
Being aware of family history: Always discuss a family history of stroke or TIA with a doctor.
Getting enough sleep and managing stress: Getting 7–8 hours of sleep and taking steps to reduce stress, such as relaxation techniques, may help to prevent stroke and improve overall health and well-being.
