The brain requires a steady supply of oxygen and nutrients to function correctly. When the blood supply to the brain is cut off, a stroke occurs. Even if the blood flow is interrupted for a short time, this might create issues. If your brain isn’t getting enough blood or oxygen, it starts to die.
The death of brain cells results in a loss of brain function. It’s possible that you won’t be able to accomplish tasks that need that section of your brain.
In India, around 70-75% of all strokes are ischemic, which means that blood supply to the brain is restricted by blood clots or fatty deposits (also referred to as plaque) in the blood vessel linings, causing the brain to become numb.
To stay aware, this blog will help you with all the basic information on stroke.
What is a stroke?
A stroke, also known as a cerebrovascular accident (CVA), occurs when a section of the brain lacks blood supply, and the body part that the blood-deprived brain cells control cannot function properly. This reduction in blood supply may be ischemic, meaning a lack of blood flow, or hemorrhagic, which means bleeding in the brain tissue.
A stroke is considered a health emergency since it has the potential to cause death or long-term damage. Ischemic strokes may be treated if detected within a few hours of the onset of the symptoms. If a stroke is suspected, the patients, families, or others should contact hospitals and request emergency medical assistance.
With a transient ischemic attack (TIA), also known as a mini-stroke, the symptoms of an ischemic stroke are only temporary and disappear on their own. The need for an emergency examination is also necessary in this case to reduce the likelihood of a future stroke. A stroke would be categorized as a transient ischemic attack if all symptoms disappeared within 24 hours.

Symptoms of Stroke
The brain’s tissues are damaged when the blood supply is cut off. When a brain region is destroyed, symptoms of a stroke might be seen in the affected bodily parts.
The faster a stroke victim receives medical attention, the better their prognosis. Because of this, it’s essential to be aware of the symptoms of a stroke so that you can take action fast. These are some of the signs of stroke:
- Numbness or weakness on one side of the body, notably in the arm, face, and leg.
- Inability to communicate or understand people
- Slurred words
- Disorientation, confusion, or a lack of attentiveness
- Sudden changes in behavior, particularly a rise in agitation.
- Vision difficulties, such as blurry or blacked-out vision in one or both eyes or double vision
- Having problems in walking
- A lack of balancing or coordination
- Unknown reason for a severe, unexpected headache
- Vomiting or nausea
There is no time to waste in the event of a stroke. A stroke may occur at any time and should be reported to emergency personnel as soon as possible. It is critical to get treatment as soon as symptoms appear to avoid:
- Damage to the brain
- Long-term impairment
With strokes, it’s preferable to be extremely cautious, so don’t hesitate to seek immediate medical attention if you suspect you or someone around you is having a stroke.

Conditions that cause Strokes
Stroke may be caused by two primary factors: an artery is blocked (ischemic stroke) or a blood vessel leaks or bursts (hemorrhagic stroke). A transient ischemic attack (TIA) is a brief interruption of blood flow to the brain that does not produce long-term signs in some persons.
This kind of stroke is the most prevalent. When the blood arteries of the brain become obstructed or constricted, blood flow to the brain is severely restricted (ischemia). A blockage or narrowing of blood arteries in the brain is induced by fatty deposits that accumulate in the vessels and blood clots or other foreign objects that move through the circulation, most frequently from the heart, and get lodged in the capillaries of the brain.
A hemorrhagic stroke happens when there is a leakage or rupture in the brain’s blood vessel. Many disorders affecting the blood arteries in the brain might cause brain hemorrhages. Hemorrhagic stroke is associated with:
- Unmanageable increase in blood pressure
- Overuse of blood-thinning medications (anticoagulants)
- Swells at weaker points in the blood vessel wall (aneurysms)
- Traumatic events like a car accident
- Protein accumulation in blood vessel walls contributes to vessel wall weakening (cerebral amyloid angiopathy)
- Hemorrhage as a result of an ischemic stroke
The bursting of an unusual network of thin-walled blood arteries (arteriovenous malformation) is an uncommon reason for bleeding in the brain.
Transient ischemic attack (TIA)
A transient ischemic attack (TIA), often called a mini-stroke, is a brief period of indications resembling a stroke. A transient ischemic attack (TIA) has no long-term consequences. Temporary loss of blood circulation to the brain may produce a TIA lasting as short as five minutes.
A TIA develops when clotting or debris restricts or prevents blood flow to a nervous system region, similar to an ischemic stroke.
If you suspect you’ve had a TIA and your symptoms have improved, seek immediate medical attention. You can’t determine whether you’re suffering a stroke or a TIA just by looking at your symptoms. You may experience a partly blocked or restricted artery going to the brain if you’ve experienced a TIA. If you have a TIA, you’re more likely to have a full-blown stroke afterward.
You must get immediate medical attention if you feel you or someone else is suffering signs of a stroke. For clot-busting medicine to be effective, it must be administered within the first few hours after the patient begins to show indications of a stroke. One of the best methods to avoid long-term problems and disabilities is to get treatment as soon as possible.
