What is brain stroke?

A brain stroke occurs when the blood vessels of the brain rupture and bleed. Blockage in the vessels of the brain is the major cause of brain stroke. The rupture or blockage prevents oxygen from reaching the vessels of the brain thereby creating the correct nervous connection. Every year brain stroke affects nearly 50,000 people worldwide. Without the presence of oxygen, the brain cells and tissues become damaged. This causes the death of the brain within a few minutes.

What are the types of a brain stroke?

There are primarily three types of strokes:

  • Transient ischemic attack (TIA): It is the type of stroke that reverses back on its own.
  • Ischemic stroke: It is caused either by the clot or plaque in the artery vessels. The symptoms or the complications concerned with Ischemic stroke last longer than TIA. chances are there that it may become permanent.
  • Hemorrhagic stroke: It is caused by the leakage of the blood or the bursting of the vessels into the brain.

What are the symptoms of a brain stroke?

Loss of blood flow is the major cause of brain stroke. Symptoms of the stroke show up when the body parts are controlled by the damaged areas of the brain. The sooner a patient gets treatment for the brain stroke, the better it becomes to save their life from the after-effects. For this reason, it is helpful to know the symptoms of brain stroke. A stroke can happen mainly because of the following symptoms:

  • paralysis
  • numbness or weakness in the limbs or especially on one side of the body
  • trouble in picking or understanding the things right exactly what is said
  • slurred speech
  • confusion, or lack of responsiveness
  • sudden behavioral changes
  • vision problems or double vision
  • trouble walking
  • loss of balance or coordination
  • dizziness
  • severe, or sudden headache for which the cause is unknown
  • seizures
  • nausea or vomiting

A brain stroke requires immediate action. If you think that anyone you know or your relative is going through a brain stroke, try helping them by reaching out to immediate medical attention. Prompt the treatment and prevent the following outcomes:

  • brain damage
  • long-term disability
  • death

It is better to be overly cautious when dealing with the cause of brain stroke. Do not be afraid or hesitant to seek medical help. If you recognize the symptoms of the stroke immediately, go right away from the doctor’s help.

What are the types of a brain stroke?

There are different types of brain stroke that affect the treatment and the medical procedure to treat it. These are:

Ischemic stroke

  • During this type of attack or stroke, the arteries supplying blood to the brain narrow in size or become blocked due to an unknown reason.
  • This causes a blood clot inside the brain. This can happen because of the pieces of plaque and their breaking off or the blockage of the blood vessels.
  • There are mainly two types of blockages that may lead to Ischemic brain stroke. These are- cerebral embolism and cerebral thrombosis.
  • A cerebral embolism takes place when a blood clot forms in any part of the body like the heart, arteries, in the upper areas of the chest and the neck. This blockage moves through the bloodstream until it hits the two arteries and lets it pass.
  • The clot gets stuck in the vessels and causes blockage in the blood flow. This causes a stroke.
  • On the other hand, cerebral thrombosis occurs when a blood clot develops fatty plaque within the blood vessels.
  • According to the researchers and their study, 87% of people suffer because of the effects of ischemic stroke.

Transient ischemic attack (TIA)

  • A transient ischemic attack is often called a ministroke. It occurs when the blood flow gets blocked temporarily.
  • The symptoms of this stroke are similar to the main cause of brain stroke. However, this can typically disappear or temporarily get back within a few minutes or hours. When the blockage moves, the blood flow can be restored.
  • The main cause of TIA blood stroke is the blockage of a blood clot. It is technically categorized as the full stroke. It is like a warning sign that can happen to anyone. Because of its causes, it is best not to ignore it.
  • Immediately seek medical help, if you see the warning signs of TIA stroke.
  • According to the studies, more than one-third of people worldwide suffer because of TIA stroke.
  • 10-15% of people experience TIA as a major stroke within three months.

Hemorrhagic stroke

A hemorrhagic stroke happens when any of the arteries in the brain break open and the blood seeps out of the vessel. The blood from that broken artery causes pressure in the skull and swells the brain. This can further damage the brain cells and tissues. There are majorly two types of hemorrhagic stroke and these are:

  • An intracerebral hemorrhagic stroke: It is the most common type of hemorrhagic stroke. It happens when the tissues of the brain surrounding the vessels get filled with blood after an artery burst.
  • A subarachnoid hemorrhagic: It is relatively less common. It causes bleeding in the area between the brain and the tissues that cover it.

According to a study, about 13 percent of strokes occur because of the major cause of hemorrhagic.

The takeaway

If you suspect the immediate cause of brain stroke, it is vital to approach for immediate medical treatment. Your doctor may provide you with clot-busting medications immediately within one hour of the stroke that may give you relief for some time. Early treatment is the best option to reduce the long-term complications and disability. While it is not always possible to completely treat and seek medical help at the time of a brain stroke, you may cause certain changes in its symptoms or effect. You can bring the reduction in the risk factors by changing your lifestyle to a healthy living. Immediate medications can also improve the way of living with brain stroke.
