What is a stroke causes symptoms and risk factors of complications diagnosis treatment prevention
brain attack
Stroke (OR: stroke - STROKE), and was known in English formerly known incident of cerebrovascular (Cerebrovascular accident - CVA) occurs when stopped, or hampered severely, blood flow to a part of the brain, depriving brain tissue of oxygen is very essential and material feeding other vital. As a result, brain cells are exposed to die within a few minutes.
Stroke is a medical emergency, and immediate treatment is a deep vital importance, as it can reduce the damage from which the brain and prevent potential post-stroke complications.
Fortunately, it is possible to address stroke. Raising the level of control of most of the risk factors of stroke, such as high blood pressure (Hypertension), smoking and excess cholesterol in the blood (High blood cholesterol), is the main reason, probably, to decrease cases of stroke.

Symptoms of Stroke
Attention should be paid to the following early signs:
Difficulties in walking: If someone stroke wounded, he stumbles, feel dizzy, loses his balance or coordination loses power (between the senses, movement and speech)
Difficulties to speak: If someone was injured stroke, it may become his shuffling or you may lose the ability to find the right words to describe what is happening to him and with him (aphasia, or loss of language - Aphasia). Try to repeat a simple sentence. If you can not do that, it is likely that you are suffering from a stroke.
Paralysis or Akhaddrar (Numbness) at one side of the body: If someone was injured stroke, you may lose sensation, or feel hemiplegia (paralysis of one side of the body). Klta tried lifting your arms over your head at the same time. If one of them began to fall, it is likely that you have a stroke.
Difficulties in vision: If someone stroke wounded, he suffers from blurred vision abruptly, you may lose the vision for a few moments, or may be suffering from diplopia (double vision, or: double vision - Diplopia)
Headaches: Headaches, which appears suddenly notice and without, or headache is normal, which may be accompanied by spasms in the neck, pain in the face, pain between the eyes, vomiting sudden or changes in cognitive status - may indicate, in some cases, the incidence of stroke .
When most people, the first sign that refers to a possible ischemic stroke is transient ischemic attack (TIA - Transient ischemic attack). And transient ischemic heart is a temporary glitch in the delivery of blood to one part of the brain.
Transient ischemic symptoms Nuba are the same symptoms of a stroke, but they continue for a time period Oqsr- than a few minutes to 24 hours, then fade and disappear without leaving any lasting damage. Someone more than transient ischemic attack and one was injured, and the signs and symptoms associated with each of them be the same or different.
The incidence of ischemic heart cross with a specific person may indicate that this person is at risk of stroke strong. It is also subjected to transient ischemic attack is more likely to have a stroke, who were not exposed to before.
The causes and risk factors for stroke
Stroke causes people with brown skin are more likely to have a stroke than people with other ethnic origins
Stroke occurs if there is a problem or an imbalance in the amount of blood coming to the brain. Causes of cerebral stroke of the most spread kind - ischemic stroke (ischemic stroke) - is to deliver a small amount of blood to the brain.
The cause of the other type of stroke - hemorrhagic stroke (hemorrhagic stroke) - it is an excess of blood in the skull.
Ischemic stroke (ischemic stroke):
This type of stroke accounts for about 80% of strokes. This stroke occurs when the brain arteries narrow or become clogged, causing a significant reduction in the amount of blood supplied to the brain (ischemia - Ischemia). This prevents, in turn, provide the brain with oxygen and nutrition of different materials, leading to the death of brain cells within a few minutes.
Types of ischemic stroke, the most common are:
Thrombotic stroke (Thrombotic stroke) - This type of stroke occurs when a thrombus / clot composed (Thrombus) in one of the arteries responsible for supplying blood to the brain. Blood clots usually occurs in areas that had been damaged by atherosclerosis, a disease in which the arteries become blocked due to the accumulation of fatty deposits (plaques). This process occurs in a head arterial (kuh - ROT - id) present in the nape of the neck and those responsible for the blood supply to the brain, such as the neck and the other in the area of the brain arteries.
Stroke, embolism (or: thromboembolic - strokeEmbolic) - happening this type of stroke when be thrombus or bulky another inside a blood vessel away from the brain, in the region of the heart, usually Wegervha the blood stream with it until it snaps into a blood vessel tightness in the area of the brain . This is called a kind of stigma clot (embolus). This situation arises, on the whole, as a result of heart rhythm disturbances in one of the upper heart chamber (atrial fibrillation - Atrial fibrillation), leads to an imbalance in supply and blood clots to be.
Hemorrhagic stroke (Hemorrhagic stroke)
This stroke occurs when a blood beginsVessels in the brain bleeding or rupture. This bleeding as a result of some medical conditions that affect blood vessels, such as hypertension and untreated mothers blood (or blood: the expansion of Casey abnormal artery or more - Aneurysm) may occur. Another less common cause of bleeding, is the rupture of blood vessels, an arteriovenous malformation (AMV - Arteriovenous malformation) is the fact that some thin-walled blood vessels, leading to torn easily. A congenital malformation. There are two types of hemorrhagic stroke: bleeding within the brain - in this type of stroke, a blood vessel bursts in the brain Vidvq blood to the brain tissue around it, causing damage to brain cells. As well as the existing brain cells beyond the leak does not get a regular supply of blood Faisebha damage, it is Alokhry.oukd cause hypertension, with time, a stroke of this kind. With the passage of time, can hypertension that makes the small blood vessels within the brain is more fragile and more prone to cracking and tearing. Subarachnoid hemorrhage - in this type of stroke, bleeding begins in a large arteries in the brain or surface area Vidvq blood in the space between the brain and the skull. This type of bleeding is accompanied by, usually, very strong headache and Fjaia.hma type of stroke is caused, mainly, to rupture or dissection of one or more of the aneurysms, which may consist bigger with time, or may be congenital (from birth). After the start of bleeding, it may expand the blood vessels in the brain narrow and irregular manner (vasospasm - vasospasm), which may cause damage to the cells due to additional declines in supply other parts of the brain with blood. There are many factors that can increase the likelihood of a stroke. Also, some of these factors may increase, too, the risk of stroke (ischemic) heart attack (myocardial infarction - AMI - Acute myocardial infarction). Risk factors for stroke include: Age: persons aged 55 years and Voagafrt blood pressure: If the systolic pressure systolic level) 140) millimeters of mercury (mmHg) or more, or diastolic pressure diastolic level) 90) millimeters of mercury (mmHg) or Oktrfert cholesterol: If the cholesterol level of 200 milligrams per deciliter (mg / dL - mg / dL) or Oktraltdechinmrd Alscrialsmonh: If the value of the body BMI) BMI 30) or Oktheromrad heart and blood vessels, including heart failure (heart failure), heart defect, inflammation of the heart or arrhythmias Kulbiskth stroke earlier or transient ischemic heart ( TIA - Transient ischemic attack) high levels of homocysteine (homocysteine), a type of pills Alomanahasthaddam acids contraceptives or hormone therapy Okhr.tmh other factors that can increase the risk of stroke include: alcohol intake and the use of the Almkhaddrat.balrgem rates stroke equally in men and women, but women are more likely than men die from stroke. Those with brown skin are more likely to have a stroke than people with ethnic origins Okhry.amadaafat stroke Damagahamadaafat stroke Damagahalochkas who have a stroke, sometimes, they become Antoaiaan and less confusion and participate in Alajtmaihtava life is the length of time that the brain has suffered through a lack of blood supply, can stroke stroke can cause a variety of disabilities that may be temporary, or potential Mstdamh.alamadaafat may be a result of the stroke vary according to the affected part of the Damag.hzh complications include: paralysis or loss of the ability to move or speak Aladilatassaobac Albulafkdan memory or problems in understanding Amoujaaalochkas who have a stroke, sometimes, they become Antoaiaan and less confusion and participate in social life.

As they should, before the start of treatment, exclude and deny other possible causes, such as tumors in the following Damag.alvhossat are tests Altafrs most common are able to determine the degree of risk of a stroke, but can also constitute a means of diagnosis, if a person has suffered a stroke : Check Jsmanatsoar waves of ultrasound (Oltrasaund - Ultrasound) carotid artery (Arteria carotis) imaging of the arteries (arteriography) computed tomography (CT) magnetic resonance imaging (MRI) echocardiography (echocardiography) stroke treatment Damagahtgay paramedics immediately intervene immediately after stroke stroke is vital and very decisively. The type of treatment to the type of cerebral ischemic stroke Damagah.alskth (Ischemic stroke): to treat ischemic stroke, doctors should resume supplying the brain with blood, as soon as Memkn.alaj by emergency medicine - should be given drugs to promote blood clotting within three hours from the moment of the emergence of the first symptoms of stroke. Prompt treatment does not increase the chances of survival, but it can also help reduce the complications that may result from stroke DamaGah.jerahh or other treatments - the physician may recommend a surgical procedure to open a blocked artery, in part or Aelia.uchml these operations: - open the artery (CEA) - install flexible mesh pillar (stent) inside the stenosis (CAS) hemorrhagic stroke (Hemorrhagic stroke) may be useful in the surgical treatment of hemorrhagic stroke or to prevent the next stroke.
