Risk Factors for Stroke


Stroke is an emergency medical treatment caused by a diminished or interrupted blood supply to a part of the brain. Early treatment of stroke may help reduce brain damage and future complications associated with the brain. Strokes can occur in people of all ages. However, if you have certain risk factors for stroke, such as high blood pressure (high blood pressure), diabetes, or arrhythmias, your chances may increase.

To work efficiently, your brain needs a constant supply of oxygen and nutrients through the blood. Stroke develops when the blood supply to the brain is reduced or interrupted. Your brain cells are depleted, leading to loss of brain function. It can be difficult to perform activities that are controlled by the part of the brain that has experienced a stroke.

Stroke can affect your ability:

● Control your emotions

● Controls bladder and intestinal movements

● Control other important functions

● Body movements such as eating, talking, and walking.

What Causes a Stroke?

Strokes are caused for two main reasons:

● Obstructed artery – known as ischemic stroke

● Blood vessel leakage – known as hemorrhagic stroke

Ischemic stroke

Ischemic stroke is the most common type of stroke. This happens when one of the major blood vessels in the brain narrows or becomes blocked. Stenosis or obstruction of blood vessels is caused by the accumulation of plaque or blood clots.

Hemorrhagic stroke

Hemorrhagic stroke develops when blood vessels in the brain leak or rupture. Factors related to cerebral hemorrhage are:

● Trauma such as accidents

● Uncontrolled hypertension

● Aneurysm – A bulge on the wall of a blood vessel

● Ischemic stroke leading to bleeding

Stroke symptoms

The symptoms of a stroke occur suddenly. Stroke symptoms vary from person to person.

Symptoms include:

● Difficult to speak and understand

● Adjustment or balance issues

● Seizures or loss of consciousness

● Numbness or weakness in the legs, arms, or face.It usually happens on one side of the body

● Difficulty in walking

● Mouth hangs down

Seek medical attention immediately if any of these symptoms occur.

What are the risk factors for stroke?

People of all ages can develop a stroke. However, some risk factors for stroke can increase your chances. Risk factors can be managed, but some cannot.

The risk factors for stroke that can be managed are:

● High blood pressure

Blood pressure above 140/90 can damage the arteries that supply blood to the brain.

● Heart disease

This is the second most common risk factor for stroke. Heart disease is also a common cause of death in stroke survivors. Stroke and heart disease have many common risk factors among them.

● Sickle cell disease (sickle cell anemia)

This hereditary disease primarily affects African-American and Hispanic children, causing “sickle cells” that are unable to carry oxygen to body tissues and organs. These cells also tend to attach to the walls of blood vessels, blocking arteries to the brain and causing a stroke.

● Hypercholesterolemia

High cholesterol levels contribute to atherosclerosis (arterial thickening and hardening due to plaque buildup). Plaque is caused by cholesterol, fatty substances, and calcium deposits.

● Use of illegal drugs

Intravenous substance abuse increases the risk of stroke due to cerebral embolism (thrombus). Drugs such as cocaine are associated with many complications, including stroke, heart attack, and other cardiovascular problems.

The risk factors for uncontrollable stroke are:

● Gender

Men are at increased risk of developing a stroke. However, women die more often from stroke than men.

● Age

Older people over the age of 55 are more likely to develop a stroke.

● Genetics

People with a family history of stroke are at increased risk of stroke.

Other risk factors for stroke are:

● Season, climate, temperature

Stroke deaths are more common during extreme temperatures and climate.

Stroke Lifestyle Risk Factors

There are several lifestyle risk factors for stroke that you can manage or control. These include:

● Obesity

● No physical activity

● Smoking

● Heavy drinking

COVID-19 and stroke

Studies have shown that COVID-19 is also one of the risk factors for stroke. Patients with COVID-19 are more likely to have thickened or sticky blood. Thick, sticky blood blocks the blood vessels that supply oxygen to the brain, increasing the risk of stroke.

What complications can occur if a stroke is left untreated?

The complications of a stroke can be temporary or permanent, depending on how long the blood supply to the brain is interrupted.

The complications are:

● Pain

Numbness, pain, or other abnormal sensations can occur in different parts of the body.

● Paralysis

A stroke can cause paralysis on one side of your body. Also, some parts of the body may lose muscle movement.

● Behavioral changes

You may feel withdrawn or need help with grooming and daily chores.

How is a stroke diagnosed?

Your doctor will do a test to diagnose a stroke. These tests include:

● CT scan

This is an image test that takes a clear picture of the brain. A CT scan of the brain helps show damage caused to brain cells and bleeding in the brain. Helps you find the type and location of your strokes.


Computed tomography Angiography (CTA) takes x-ray images of blood vessels. Helps detect vascular damage.


MRI scans use a magnetic field to help detect changes in brain tissue.


Magnetic resonance angiography (MRA) helps check blood flow through arteries.

What are the treatment options for stroke?

Your doctor will consider your age, health, type, severity, and cause of stroke before planning your treatment. When a stroke occurs, it cannot be cured. However, there are many medical and surgical treatment options available that can reduce the chances of a second stroke.

The treatment options for stroke are:

● Thrombus destroyer

These medicines are used to eliminate blood clots caused by lack of oxygen. They also help reduce the damage caused to the brain. To be effective, the drug must be given within 3 hours of the onset of the stroke.

● Neuroprotective drugs

These drugs help protect the brain from oxygen deficiency and other injuries.

● Drugs that reduce cerebral edema

Special intravenous fluids are used to reduce cerebral edema. These drugs are usually given after a hemorrhagic stroke.

Surgical treatment options

● Carotid artery stenting

A stent (a large metal coil) is placed in the carotid artery. This is similar to a stent placed in the coronary artery.

● Carotid endarterectomy

This is a surgical procedure performed to remove blood clots and plaque from blood vessels. Endarterectomy may help reduce the chance of a second stroke.

● Craniotomy

This is a type of neurosurgery that removes blood clots, relieves pressure, and repairs bleeding in the brain.


Stroke is an emergency medical treatment and needs immediate treatment. If not treated on time, it can lead to serious brain damage and future complications. Many of the risk factors for stroke can be managed or modified. It may help reduce the chance of developing a second stroke.

Frequently Asked Questions (FAQ)

1. Can the brain repair itself after a stroke?

The first recovery after a stroke is due to reduced swelling and improved blood circulation in the brain. Damaged cells that can be repaired begin to heal themselves and function normally. However, long-term treatment options and rehabilitation are just as important.

2. Can you feel a stroke coming?

There are many warning signs of stroke. The most important are weakness of the arms, sagging of the face, and indistinct speech. Seek medical attention immediately if any of these warning signs occur.

3. What is a silent stroke?

In some cases, people have a stroke and do not feel it. It is called a silent stroke, or silent stroke. It is caused by a blood clot in the brain. Silentstroke is a sign of progressive brain injury and a risk factor for future stroke.
