A stroke is synonymously used to describe a blood clot in the brain. Another term that is often used to describe a stroke is a brain attack. A stroke occurs when blood cannot flow to a part of the brain or a reduced amount of blood flows to the brain. When this happens, the brain's tissues cannot get the required nutrients and oxygen.

If this goes on for too long, then the cells in the brain begin to die. A stroke brain clot is considered a medical emergency, which is why promptly treating the problem should be the priority. The earlier the action is taken, the higher the chances of recovery.

Frequently Asked Questions About Blood Clots in the Brain

Warning Signs and Symptoms of Blood Clots

Blood clots can form in different parts of the body, leading to serious health complications if not addressed promptly. Recognising the warning signs can help prevent life-threatening conditions such as deep vein thrombosis (DVT), pulmonary embolism (PE), or clot-related complications in the brain or heart. If you or someone you know experiences any of the following symptoms, seek medical attention immediately.

Speech difficulties and confusion: If a blood clot disrupts blood flow to the brain, you may struggle to form words, have difficulty speaking, or experience sudden confusion. Your speech may become slurred, making it hard for others to understand you.
Trouble swallowing: In some cases, a blood clot in the brain or neck arteries may cause difficulty swallowing. You may feel as if you are choking when attempting to swallow food or liquids.
Sudden vision problems: A blood clot affecting the brain or eyes can lead to blurred vision, double vision, or even temporary vision loss in one or both eyes.
Severe headache: A sudden, intense headache can be a sign of a blood clot in the brain, such as cerebral venous sinus thrombosis (CVST). This may occur alone or alongside other symptoms such as nausea, dizziness, or vomiting.
Swelling, pain, or redness in the limbs: A blood clot in a deep vein, such as in the legs (DVT), can cause swelling, warmth, redness, and pain in the affected limb. This usually occurs on one leg rather than both.
Difficulty breathing or chest pain: A blood clot that travels to the lungs (pulmonary embolism) can cause sudden shortness of breath, chest pain that worsens with deep breaths, rapid heartbeat, and even coughing up blood. This is a medical emergency.
Numbness or paralysis on one side: A clot blocking blood flow to the brain can lead to numbness or weakness in the face, arm, or leg, typically on one side of the body. Your mouth may droop, and when you try to raise both arms, one may not lift properly.
Loss of balance and coordination: If a clot affects circulation to the brain, you may experience dizziness, difficulty walking, or a loss of coordination, making it hard to maintain balance.

Types Of Strokes

1. Ischemic stroke

About 90% of strokes are ischemic strokes. A brain blood clot causes this stroke. A clot in the brain stops the blood flow that travels to the neck or brain. The clot in the brain is formed inside the blood vessel, and there can be more than one clot. The blood clot in the brain doesn't need to be the only reason a stroke occurs. If clots form in the upper chest or the heart, and the clot somehow blocks the blood that is flowing to the brain, then you can still get a stroke; it is known as cerebral embolism. There is a chance that the clot can dissolve by itself, and if this happens, it is called a transient ischemic attack or TIA.

2. Haemorrhagic stroke

Haemorrhagic stroke is another major stroke. This type of stroke is associated with bleeding that takes place in the brain and is usually the deadlier stroke variant. Usually, a hemorrhagic stroke occurs after an aneurysm. In this, part of the weak artery becomes more extensive, which eventually leads to its bursting. Another scenario that can cause a haemorrhagic stroke is when the artery wall breaks because of fatty plaque. It happens over time and then can lead to haemorrhagic stroke. Blood thinners can cause brain haemorrhage; also, hypertension is another significant cause of brain haemorrhage.

3. There are two types of hemorrhagic strokes-

subarachnoid haemorrhage and intracerebral haemorrhage. In subarachnoid haemorrhage, one of the leading causes is an aneurysm burst. In this, the blood vessels start to narrow and widen, which can cause brain cell damage. It limits blood flow to the brain, which can cause further damage. Another cause is when an artery found near the brain's surface bursts. It causes the blood to spill between the skull and the brain, leading to severe headaches. The intense headaches indicate that bleeding has occurred.

Certain medications, such as blood thinning, high blood pressure, or vascular malformations, can cause intracerebral haemorrhage. Some other conditions can also cause an intracerebral haemorrhage. In this type of stroke, a blood vessel in the brain ruptures. When this happens, the blood is spilt where it reaches the brain tissue, and it can harm the brain cells. The brain cells unaffected by this are affected by the lack of blood supply. This results in damage to blood cells until they eventually begin to die.

Are You at Risk?

The following are some factors that make you vulnerable to stroke.

If you have a family history of someone who had a stroke, then you are pretty likely to get a stroke.
People who are 65 or older are more prone to stroke, although younger people can have heart strokes, as well.
Any medicine that is used for blood thinning increases your chances of having a stroke. Medicines such as Warfarin and Apixaban are prime examples.
People who have had a stroke before are likely to have a stroke again.
People in ethnic groups such as Alaska Natives, Hispanic descent, Native Americans, and African Americans are more likely to have a stroke.
Strokes affect more men than women, although it is more likely to affect women more severely than men.
You are more likely to have a stroke if you don't exercise, use drugs, regularly smoke, or drink alcohol regularly.
Obese people are at risk of having a stroke.
Women who are pregnant can experience a stroke. Women who have taken birth control pills are highly likely to have a stroke, too.
People who have conditions such as PCOS, sickle cell disease, diabetes, brain tumours, migraines, and conditions associated with excess bleeding are more prone to stroke.
People who have vascular or heart problems are more at risk of stroke.

Complications That May Arise

Here are some complications that may arise after a stroke:

People who have experienced a stroke are more likely to become depressed. It can cause various emotional problems to crop up. People may have difficulty controlling their feelings, which can impact them profoundly.
People who have experienced a stroke may want to be alone all the time. They may become more withdrawn and not want to speak to others. They might become more impulsive, too.
Stroke survivors may lose the ability to take care of themselves after they have suffered from a stroke. They may need help doing daily chores that were once easy for them. It means they will need help grooming themselves, too.
People can have muscle movement-related problems. One side of the body may become paralysed, or control over specific muscles may be lost. Usually, one of the arms or one side of the face is affected.
People who have had a stroke are more likely to develop memory problems. 1 in 4 people are likely to have dementia after they have had a stroke, and it is more prevalent in men than women.
People who have had a stroke may experience a tough time when they try to swallow. It is because a stroke can affect your throat and mouth muscles. People can have trouble talking after a stroke, too.
People who have had a stroke may have difficulty understanding things. It means their ability to make proper decisions is impaired as a result. People may have difficulty thinking clearly and with reasoning abilities, too.
People may feel tingling in the body part affected by the stroke. They can experience pain in some regions of their body, too. Some may experience numbness in the parts affected by the stroke.

Diagnosis Of a Stroke

Firstly, your doctor will perform a physical exam. Then, your blood pressure will be checked, and the doctor will observe your heartbeat. The doctor will want to ensure that stroke symptoms are not caused by other conditions such as a heart problem, migraines, or low blood sugar. They will ask you about what you are experiencing and how you feel now. They will ask you whether you have speech or vision trouble, trouble paying attention, or numbness in any part of your body. He will check your balance and coordination and see if you are having trouble.

Once this is complete, he will perform two types of tests: blood and imaging. These are used to determine the type of stroke that you have. In a blood test, two particular factors will be checked- clotting time and complete blood count. In the blood count test, the number of platelets and electrolyte levels is going to be checked. For computing blood clotting time, the prothrombin time test or PT and partial thromboplastin time or PTT are two tests that are used. Your doctor will check the blood clot rates, and if there is a problem, it will be shown as a delay in blood clotting.

Various imaging tests can be done; for instance, a carotid ultrasound will help find the fatty plaque causing problems by blocking the arteries that carry blood to the brain. Angiograms help determine whether there is any blockage in your blood vessels. These tests are done on your neck and head. CT is another test that helps determine if bleeding in your brain has occurred. CT can help determine if your brain cells have been damaged. An echocardiogram is another test that helps determine whether clots are present in your heart. MRI helps create a detailed brain picture so that any injuries to the brain can be detected.

Treatment in Case of Stroke

Emergency Treatment in Case of Stroke

A stroke is an emergency. If you experience it, you should contact emergency services immediately. If you receive quick treatment, your chances of recovery are higher, and you are more likely to survive. There are different emergency treatments, and they depend on the type of stroke.

Even a tiny blood clot in the brain can result in ischemic stroke. When you have an ischemic stroke, the doctor will try to dissolve the clot. Usually, aspirin is given to ensure no further formation of clots. Otherwise, clot-busting drugs such as thrombolytics will be provided in the case of ischemic stroke. Another type of emergency treatment can be mechanical thrombectomy. It uses catheters to remove the clot from the affected artery. This medical procedure can take place a day after stroke symptoms appear. Sometimes, surgery may be necessary to reduce the pressure in the brain.

If the doctor has found that it is a hemorrhagic stroke, then certain medications will be given. These helps reduce the bleeding, and they help to decrease blood pressure as well. If you take blood-thinning medications, your doctors will prescribe medications to stop their effects because blood thinners worsen bleeding. Surgery might be required in some cases, but this depends on how severe the blood loss is. In the surgery, excess blood is removed so your brain is not under pressure. The surgery will help repair the blood vessels that have been damaged during the stroke.

Prevention of a Stroke

There are many ways to prevent a stroke. The following are some strategies.

People with hypertension should control their blood pressure. This can be done by taking medications prescribed by their doctor and limiting their sodium intake. Stress management and weight management are also important.
You should quit smoking because it increases the risk of a stroke. You should avoid secondhand smoke as well.
Weight is an important factor that you should not ignore. Obese and overweight people are more prone to stroke, which is why lowering your Weight can be beneficial. It can also help lower cholesterol levels and blood pressure.
If you have diabetes, then you should ensure that you are taking your medicines and can successfully manage your diabetes.
Cholesterol raises the risk of stroke, so it is recommended that you control your cholesterol level. You can do this by making changes to your diet, such as decreasing your consumption of foods that are high in trans fats and saturated fats.
You should avoid taking illegal drugs such as cocaine. When you take cocaine, it causes your arteries to narrow, which in turn decreases the flow of blood, which increases the chances of stroke.
Regular exercise and keeping fit are good ways to maintain overall health and reduce the risk of a stroke. Include cardio exercise in your regime, as this helps to improve blood vessel health and is great for your heart. Aim for at least 30 minutes of exercise every day.
You should avoid drinking alcohol, and if you do need to drink, then drink in moderation. If you take medications, then speak to your doctor about how much liquor you can consume safely.
You must include vegetables and fruits in your diet. Fresh fruits and vegetables with high fibre content are recommended as these help prevent strokes. You can try the Mediterranean diet, but consult your doctor before resorting to any diet.
You can speak to your doctor about what changes you need to make to prevent a stroke from occurring.

Treatment Options to Consider

In addition to the treatment options discussed above, other options are available in the emergency treatment section. For instance, in the case of an ischemic stroke, your doctor might recommend procedures to prevent a stroke from recurring. Carotid endarterectomy is one of the recommended medical procedures. In this process, plaque is removed from carotid arteries through an incision, which is then completed with stitching. This procedure is risky for people who have certain medical conditions or who are suffering from heart problems. Another option is using angioplasty and stents.

In hemorrhagic stroke, there are additional treatment options that are available if AVM or any vascular malformation has caused the stroke. Endovascular embolization is an option that helps the blood to clot. Another option is stereotactic radiosurgery, which allows the treatment of vascular malformations. Your doctor might recommend surgical clipping. This procedure prevents an aneurysm from bursting; It can also help prevent further bleeding. Another medical procedure that is an option is surgical AVM removal. It is only possible if the AVM is small and easily accessed in your brain.

Did You Know?

Major brain clot symptoms can appear suddenly and may include severe headaches, vision problems, numbness or weakness on one side of the body, dizziness, and difficulty speaking. Immediate medical attention is crucial to prevent serious complications.
Blood clots can form in zero gravity! Astronauts in space have experienced unexpected clot formation due to fluid shifts in the body, highlighting how gravity plays a crucial role in blood circulation on Earth.

Road To Recovery

How you recover depends on how the stroke impacted you. The area of impact and the severity of the damage will help determine how you can recover. If brain tissue on the right side of your brain is affected during the stroke, then your senses and movement of the left side of your body are affected. If brain tissue on the left side of your brain is affected, the impact can be seen on the right side of your body. You can experience movement-related problems, speech problems, and language difficulties. The road to recovery from a stroke can be a tough one. Different people react differently to a stroke.

Some people can return to their usual activities within a few days after a stroke. It can take many months for other people to return to normal. For some people, it can take some years to return to their usual selves and do what they can comfortably do. Recovery is an ongoing process, and being positive throughout the whole process is the way to go when it comes to stroke. Knowing about what you can do to prevent stroke in the future is something you should speak to your doctor about, too. It would help if you openly talked to your doctor about any doubts and questions regarding aftercare.
