Symptoms, Causes And Diagnosis Of Stroke. When the blood supply to the brain is cut off, that is what is called a stroke. A stroke is a serious medical condition when handling quickly is very important. Because the sooner survivors treated, damage happened ever is getting smaller.
Please contact the hospital to ask for an ambulance if you experience the symptoms of stroke or see other people affected by stroke. After the initial examination, you may need to be checked more thoroughly and dealt with a specialist at the hospital.
Don't ever consider lightly stroke symptoms, though the symptoms disappear. The symptoms could indicate a missing light strokes and you are at risk of experiencing a stroke weight in the next phase.

| Symptoms, Causes And Diagnosis Of Stroke |
Symptoms and signs of a stroke you should know
Every part of the body controlled by different parts of the brain, because it stroke symptoms depending on the parts of the brain are stricken and also the level of damage. Symptoms or signs of a stroke vary on everyone, but generally appear unexpectedly.
You can remember the following things to be able to recognize the symptoms of stroke and take actions appropriate.
- How to talk the sufferer is not obvious or even chaotic, there is also a sufferer who could not talk at all, even though they look awake
- Eyes and mouth on one side of the face of the sufferer looks down
- Arm the sufferer experiencing paralysis when the stroke, therefore they are not able to appoint one, or even both of his arms
Immediately contact your local hospital if you see the above symptoms
Aware of the symptoms or signs of the above is the important thing, especially for those who live with people who are at high risk of stroke-affected, such as the elderly,people with diabetes, or high blood pressure.
In addition to the above, symptoms or signs of a stroke are:
- Difficulty swallowing
- Problem on balance and coordination
- Communication problems, such as the tough talk and understand the speech of another person
- Dizziness and fainting
- Lost suddenly vision
- Terrific headache which comes unexpectedly, accompanied by a stiff neck
- Paralysis on one side of the body
Ischemic attack symptoms shortly or stroke lightly
If you have a moment, ischemic attacks soon check with your doctor or local hospital.Symptoms of stroke: ischemic stroke is the same as for a moment and takes a few minutes to a few hours, then disappeared. Don't ignore momentary ischemic attacks, because it is a warning sign that supply blood to your brain is problematic.
Causes Of Stroke
Most of the causes of stroke can be prevented by means of changing Your life patterns into the pattern of healthy living. Even so, there is some risk of stroke that can not be changed, and the matter will be explained below.
- If you ever experience a momentary ischemic attack or a heart attack, the risk you are exposed to higher stroke
- Your risk of stroke is high if you have close family members who have experienced stroke
- You are at risk of stroke if you are over the age of 65 years, although a quarter of stroke cases occur at a younger age
- Suffering from diabetes, high blood pressure or have high cholesterol.
Regarding information on ischemic stroke
Ischemic stroke occurs when blood flow to the brain is stalled due to the formation of blood clots. The blood easily clot in blood vessels where there is heap damage has occured or cholesterol on the walls. These are the things that impacted badly on the blood vessel so that it can trigger the onset of ischemic stoke:
- High cholesterol levels in the blood.
- Uncontrolled diabetes. High blood sugar levels be bad on the health of the blood vessel walls.
An irregular heartbeat or atrial fibrillation is also one of the causes of ischemic stroke.With an irregular heartbeat, blood flow is impaired atrial fribrilasi sufferers. It also makes easy blood clot causing ischemic stroke.
The artery can also narrows as you get older, and the process of narrowing of the arteries can grow quickly if you:
- Are obese
- Have high blood pressure
- Excessive alcohol consumption
- Smoke
- Have a high cholesterol level
- Have a family history of diseased heart or diabetes
Regarding information on stroke hemoragik
Hemoragik stroke occurs when a blood vessel in the brain ruptures and causes bleeding. About five percent of the bleeding occurs at the surface of the brain known as a subarachnoid hemorrhage. High blood pressure is a leading cause of stroke hemoragik. High blood pressure can weaken the artery in the brain so vulnerable to rupture.
There are several things that can trigger a rise in blood pressure, such as smoking, lack of exercise, stress, excessive alcohol consumption, and overweight or obesity.
Hemoragik stroke can also occur due to rupture of blood vessels that bubbled or swelling called aneurysms.
Trauma or injury to the head can also cause stroke hemoragik. However, there are some cases where bleeding occurs in the brain membranes without any signs of trauma. It usually occurs in the elderly and symptoms similar to a stroke. Bleeding that occurs in the brain membrane known as a subdural hematoma.
People who consume drugs preventive blood clotting or anticoagulants also should be careful. One of the risks from the use of this drug is the stroke hemoragik.Anticoagulant drugs make the blood becomes more difficult to clot. This means, if there is bleeding, the bleeding it will be hard to stop.
Diagnosis Of Stroke
Stroke is generally diagnosed through physical tests, as well as through brain imaging or photo. The taking of photos of the brain use to determine whether a stroke caused by blocked arteries or blood vessels that burst, the existence of a risk of ischemic stroke attack, which parts of the brain are stricken, and how severe the stroke.
In addition, the doctor will also examine the cause of the stroke by checking the heart rate, blood pressure, and the measure doing blood tests to find out the level of cholesterol and glucose.
Each type of stroke require different handling. The treatment will be easier if supported by a rapid diagnosis.
Stroke diagnosis using CT scans and MRI scans
The type of scan that you are living in the hospital depends on the symptoms. There are two common methods used in the shooting, the first brain CT scan or computer tomography scanning. This scan is the same as x-rays, but wear a few images to forma three-dimensional image that is more detailed. A common method is both an MRI scan or a magnetic resonance imaging scan. This scan uses magnetic fields and radio waves to produce images of the body in detail.
A CT scan is enough to identify whether the stroke is caused by bleeding or clotting. If you are having a great stroke, this scan is suitable for you. This scan is faster than MRI scans and in some cases, increase the chances of granting a remedy in a quick and precise.
For patients who have been cured of a momentary and for ischemic attack sufferers have symptoms of more complex, where the location and extent of the damage is not known, an MRI scan is more appropriate. This scan yields images of brain tissue that is more detailed, so as to allow unidentified stroke in unusual parts.
The process of taking pictures of blood vessels of the brain and blood vessels of the neck that starts with injecting a dye substances pass through blood vessels in the armcalled CT angiography or MR.
Scanning the brain must be carried to all patients who allegedly suffered a stroke in the past 24 hours. However there are some patients who should be scanned immediately in the next one, especially for those who:
- Have a lower level of awareness
- Anticoagulant treatment is undergoing
- Dependent on drugs such as alteplase or clot busting new anticoagulant treatment
Swallow test to prevent infection of lung
A third of people experience problems in swallowing post stroke. If a person cannot swallow properly, then her lungs are at risk of importation of food. It can cause pneumonia and infection in the lungs.
Swallow test done by very important people who have experienced a stroke. The test is quite simple. Patients need only drank a few spoons of water. If the patient is able to SIP the water without choking and coughing, they will be asked to SIP a half a glass of water. If they are not able to SIP, then they will be referred to the occupational therapist related to be examined in more detail.
Before the review, the therapist typically barred sufferers swallow anything. Therefore,the food and drinks that get into the body through an IV drip or use nasogastrik hose through the nose.
Make sure the cause of the stroke with a test of heart and blood vessels
Examination of blood vessels and the heart will be done to ensure the cause of stroke.There are three types of review process, among others is the echocardiogram, catheterangiography or arteriography, and carotid ultrasound or ultrasonography.
Diagnosis of stroke with Echocardiogram
Echocardiogram may be used in a number of cases. One of these examinations is called transthoracic echocardiogram, examination using an ultrasound tool placed on the chest to produce images of the heart.
The second is transoesophageal echocardiography. This examination using an ultrasonic instruments are relegated to channel food and usually the patient is sedated in advance. Because right behind the heart, this inspection yielded images of blood clotting and other abnormalities are obvious and cannot be done by a trasthoracic echocardiogram.
Stroke diagnosis with Ultrasound or carotid ultrasound
This is another way that used a doctor to check if there is a narrowing or clotting in the arteries leading to the brain. The instrument used is a tool shaped like a stick otherwise known as a transducer. Through these tools, high-frequency sound waves are sent into the neck. Waves flowing through the body's tissues will then form a picture. From the pictures that the doctor will know the points of narrowing in the artery when there is.
If needed, the inspection should be done in the next 48 hours. Ultrasound scan like this also has other known in General, i.e. duplex doppler scan or scan.
Diagnosis of stroke with the Angiography catheter
This inspection is carried out by means of injecting a dye through the carotid artery or the spine. The results obtained in this examination more detailed compared to results obtained with ultrasound examination, CT scans, or MR angiography.
