What are the warning signs and manifestations of a stroke?
How can we know if a stroke is likely to occur? If you want to know more about stroke and its warning signs, we recommend that you read on.
Stroke is a very serious and sometimes fatal and life threatening complication. Strokes are caused by impaired blood supply and oxygen supply to parts of the brain tissue. This circulatory disorder occurs for two reasons. Or one or more arteries in the brain are blocked The blockage is caused by a blood clot, or one of the arteries that supplies that part of the brain tissue is bleeding. So strokes are divided into ischemic and hemorrhagic. In the following, we want to make you more familiar with strokes and its warning signs.
What is a stroke?
If the blood supply to a part of the brain tissue is disrupted or stopped for some reason, that part of the brain can no longer function normally. This general condition is called a stroke or brain attack or cerebrovascular accident.
The cause of a stroke can be either the closure of one or more blood vessels in the brain, called ischemic strokes, or the rupture of blood vessels in the brain, which are called referral strokes. Strokes will eventually cause changes in brain function.
The changes are usually acute and occur due to acute and sudden damage to brain cells. Sometimes, due to the severity of the damage, a number of brain tissue cells whose blood flow is interrupted are killed. The changes made will cause changes and alterations in the appearance and function and normal movements of the person who has suffered a stroke.
What happens during a stroke?
These types of strokes are very similar to heart attacks, but the difference is that they occur in the brain. Traumatic brain injury and Stroke are like a heart attack in a medical emergency. In this case, the emergency department should be contacted immediately without delay.
During heart attacks and strokes, a person may not be able to speak and move their arms and legs as before. Stroke occurs due to the reduction and cessation of blood supply to brain cells. So sometimes a stroke is also called brain attack, abbreviated as cardiovascular oxidant or CVA.
What are the signs and symptoms of a stroke?
The manifestations and symptoms of a stroke depend entirely on the location of the accident and the extent of damage to the brain tissue in that area. So we have to say that different people who experience a stroke will have completely different signs and symptoms. Stroke can cause the following:
Hemiplegia: Doctors call paralysis of one half of the body, which is on the opposite side of the damaged hemisphere of the brain and occurs following a stroke:
- Emotional problems
- Cognitive problems
- Perceptual disorders
- Impaired balance
- Blurred vision
- Change the appearance of the face and facial mimicry
- Change the position of the tongue inside the mouth
The above are some of the complications that most commonly occur following a stroke in an individual at the time of the accident.
In describing the symptoms of a stroke, we must emphasize that the symptoms vary from person to person and depend on which part of the brain and how much of the brain tissue is involved.
Symptoms usually appear suddenly, meaning the symptoms are complete within minutes to an hour, and usually these symptoms are not accompanied by any pain. One-third of all strokes occur during sleep, so people who notice symptoms for the first time after waking up find it difficult to determine when a stroke will occur.
Another point to note is that the symptoms that we are going to treat as signs and manifestations of a stroke may appear temporarily and transiently or disappear completely in less than twenty-four hours. This condition is called transient ischemic stroke (TIA).
The following are some of the most common warning signs and clinical manifestations of stroke that may occur, and a brief description of each is provided.
- The first sign of weakness in the arm or leg on one side of the body or both sides
A person who has had a stroke can feel very mild weakness to complete paralysis in one or both limbs. There may be a tingling or tingling sensation on one side or part of the body.
- The second manifestation and sign of feeling weak in the face
A person with a stroke may feel that their face is weak and loose
Or when he looks in the mirror, part of his face looks crooked. The patient may not be able to control the movements of his lips or tongue. His speech may also be misunderstood due to a problem with his or her language.
- The third manifestation is the occurrence of speech problems
A person with a stroke or Cerebrovascular accident may not be able to speak as well as they used to, or their speech may become very irrelevant and unintelligible, or when he speaks, the words have no problem, That is, he utters the words well, but what he says and the sentences he utters are completely meaningless and incomprehensible. It is in these cases that speech therapy helps the person because it corrects the created disability as much as possible.
- Symbol and pretend number four confused
A person with a heart attack or stroke may experience dizziness, lightheadedness, or vertigo, or be unable to maintain balance.
- Sign and Demonstration Number Five Create Problems in Coordination
A person who has had a stroke or cerebrovascular accident may appear to have poor coordination, stagger, and have difficulty walking or lifting objects.
- Symptom and manifestation number six sudden headache
A number of people who suffer from stroke and cerebrovascular accidents report that they suddenly experienced a severe headache without any introduction.
- Signs and manifestations of the number seven occurrence of vision problems
Sometimes a person with a cerebrovascular accident may experience vision problems. For example, people with stroke may have diplopia or lose their sight completely. The person may also lose lateral or lateral vision.
Doctors say blurred vision alone cannot be a manifestation of a stroke.
- Symptoms and manifestations of number eight disorders of language and thinking
In this case, the person does not understand the professions of others or the material that is written and placed in front of him, and despite the fact that he was already able to read and write, now he can not read the material or write anything.
Sometimes a person can not even express his thoughts, and sometimes he develops memory or learning disabilities.
- Sign and pretend number nine loss of consciousness
A person may lose consciousness or become unconscious or no longer conscious due to impaired blood flow to more vital parts of the brain.
Signs and manifestations of the number ten emotional problems
One of the things that a person with a stroke can experience is experiencing emotional problems. A stroke can cause a person to feel fear, anger, unreasonable anger, sadness, grief and anxiety.
What are the causes of a stroke?
Doctors cite two main causes of stroke
Obstructive and bleeding causes.
In general, anything that causes a stroke can damage or disrupt the blood vessels in the brain, interrupting, disrupting or cutting off blood flow to a part of the brain tissue.
- Obstructive strokes
Doctors call these strokes ischemic strokes
Ischemic stroke occurs when there is a blood clot in one or more types of cerebral arteries that restricts and blocks blood flow to the brain. Eighty-five percent of all strokes are due to this. Obstruction of arteries or arteries that prevent full blood flow to the brain tissue It may have occurred in or around the brain. Blood clots may also be brought to the brain by blood flow from other parts.
The causes of obstructive strokes are as follows:
- Deposition of fat and the formation of plaques on the walls of the arteries and the common presence of atherosclerotic plaques in the cervical arteries or carotid arteries.
- Heart problems and cardiac arrhythmias that lead to the formation of blood clots. These clots move inside the arteries and reach the brain, blocking the blood vessels in the brain.
- Bleeding strokes
Bleeding strokes are less common than obstructive strokes
If a blood vessel that is weak and responsible for blood supply to the brain ruptures, these types of strokes occur, and thus, in addition to reducing the blood flow that reaches the target area of the brain, the blood enters the brain freely and damages and destroys the brain cells as it spreads.
If the amount of blood leakage is high, it will gradually increase the pressure inside the skull. The skull is a bony area and does not have the ability to increase volume so Going backwards causes the pressure inside the skull to increase. Increased leaking blood volume puts pressure on the brain tissue, compresses the brain, and kills critical areas of the brain.
Although the prevalence of hemorrhagic strokes is only 15 percent of all strokes, they are usually more dangerous and serious than obstructive strokes. It is said that 30 to 50 percent of all people who have a stroke die.
It is said that when a person has a bleeding stroke, the main goal of the treatment team will be to stop or prevent bleeding and blood leakage into the brain tissue.
The reasons why hemorrhagic stroke occurs can be explained in the following cases:
- High blood pressure:
High blood pressure weakens the walls of the arteries and makes them easier to rupture.
- Atherosclerosis, which causes the arteries in the brain to become brittle
- Strokes and traumas to the brain
- Weakening of a spot in the vessel wall that can be easily torn
- Excessive alcohol consumption also increases the risk of this type of stroke.
What are the risk factors for having a stroke?
The question here is who is more likely to have a stroke or Cerebral Vascular Events. In the following, we will answer the above question.
Older people are more at risk than others, but anyone at any age, even children, for example, can be victims of this serious condition due to congenital cerebrovascular problems.
Risk factors that play a role in stroke include the following:
- Improper use of alcoholic beverages
- High blood pressure
- Narrowing of the arteries and ischemic heart disease
- lack of movement
- Taking birth control pills
- Obesity and overweight
Doctors believe that high blood pressure is the most important risk factor for stroke and cerebrovascular accidents. Blood pressure control if done properly and properly Thirty to forty percent can reduce the risk of stroke in a susceptible person. According to statistics, people who use cigarettes and tobacco are twice as likely to have a stroke as non-smokers. It is said that when a smoker quits smoking, the prevalence of stroke two to five years after complete smoking cessation becomes like a group who have not smoked.
People with insulin-dependent diabetes are two to six times more likely to have a stroke.
What are the complications of strokes?
One in four people who have a stroke will die, and survivors may also suffer from long-term complications from brain injuries.
Many patients are said to be able to regain their former independence after a long time and rehabilitation, but Unfortunately, many people who have a stroke or are survivors of a stroke do not fully recover and have to make lifestyle changes.
Or they become somewhat dependent on those around them to survive, and one of the side effects of a stroke is that fifty percent of stroke victims become dependent on those around them to perform daily activities and even take care of themselves.
How we can treat a stroke is a very general question. The methods used to treat a stroke are related to the type of stroke and the location of the brain injury, and what caused it. Here are some common ways to treat a person with a stroke that we will mention and briefly explain.
Strokes are often treated with drugs, and what role do drugs play in treating strokes?
We must say that the main role of these drugs in the treatment of stroke is to prevent the formation of blood clots or to dissolve and destroy clots. And also Medications that are prescribed should also be able to lower blood pressure and control and balance blood lipid levels.
In general, anticoagulants, antihypertensive drugs, and lipid-balancing drugs are among the essential drugs used to treat stroke. If a person has a cerebrovascular complication following a heart disorder, appropriate medication should also be prescribed to manage their heart problem.
Sometimes it is necessary to restore coordination and physical strength through exercise. In fact, standard exercise strengthens the motor skills of a person with a stroke, And training in motor skills is often used to enable a person to make good use of a cane or walker while walking.
It is also sometimes necessary to take advantage of treatment restrictions. Because in this method, the use of non-involved organs is limited so that we can work more on improving the function of the involved organs. When we want to reduce muscle cramps, we may use range of motion therapy and exercise.
Sometimes it is necessary to use activities with the help of advanced devices in a person who has had a stroke.
In this section, practical and specialized instructions of specialized doctors will help the patient. Physiotherapists interact with other members of the treatment team and do their best to eliminate the complications of a stroke.
The patient should start a treatment and physiotherapy program under the supervision of an experienced physiotherapist as soon as possible after receiving the initial treatment. If the patient is clinically stable, doctors will usually refer him or her to a physiotherapist within forty-eight hours of having a stroke.
If a stroke has occurred and the intracranial pressure is high, surgery may be needed. The goal of surgery is to eliminate and reduce the chance of re-bleeding. This is usually common in hemorrhagic strokes because the brain cannot replace the damaged cells with new ones.
The patient’s recovery depends on the brain’s ability to organize healthy cells and therefore compensate for lost cells. Doctors call this innate ability of the brain neuroplasty
