A stroke is the result of a sudden circulatory disorder or bleeding in the brain. With these processes in the nerve cells of the brain deprived of oxygen and nutrients and die. This can lead to permanent loss of function of the symptoms of system problems and cause central nervous as speech and paralysis.Every year about 20,000 people in Austria as a stroke; This means there is an average of six minutes in a stroke. stroke mortality in recent years fallen dramatically, shots are still in the statistics on causes of death worldwide and ranks second among the industrialized nations of the most common causes of disability in the elderly.The risk of stroke increases with age and more than 50% of all strokes occur in the group of people over 75 years. However, young people can suffer from a stroke. It is estimated that nearly 5% of all those affected are younger than 40 years.
What causes a stroke?
There are two types of stroke: ischemic stroke, by a container closure (80% of cases) is caused, and hemorrhagic stroke, caused by the brain (20% of cases) bleeding. Several factors can lead to vascular occlusion or cerebral hemorrhage.
The causes of ischemic stroke
Ischemic stroke is caused by blockage of a blood vessel in the brain. This leads to an insufficient supply of blood and oxygen. The affected tissue dies and forms a scar similar to a heart attack. Therefore, the ischemic stroke is also called stroke.

The causes of hemorrhagic stroke
A hemorrhagic stroke occurs primarily through a container bursting. The product container respective regions do not receive enough blood and the blood more depressed because of oxygen-rich neurons.

What are the symptoms of a stroke?
Symptoms of stroke due to the fact that parts of the brain to regulate their function and die from lack of oxygen. What neurological deficit, they will be made and how pronounced it depends on the brain regions that are affected and what is the extent of the injury.
In most cases, there is a paralysis and sense of touch disorders (numbness), which is usually limited to a body. Other symptoms of a stroke are speech, vision or difficulty swallowing, dizziness, confusion and, in severe cases, unconsciousness conscience problems. It is significant that the symptoms running suddenly – as it suddenly.Although both types of strokes can cause headaches, they do occur, but especially if hemorrhagic infarction. Tear off a ship in the area around the skin of the spinning brain (SAH), the parties almost always a headache and stiff neck, often follow by nausea, vomiting, senceto light and sound.In general, often due to stroke, nausea and vomiting. A recurring complication is the subsequent inhalation of vomit. This leads to damage of the lung tissue often associated pneumonia.
What are the symptoms of a stroke defined?
According to the World Health Organization (WHO), there are only a stroke if symptoms for at least 24 hours to stop. neurological deficits in this full-time course of study, called a temporary attack (ie temporary) ischemic (TIA). Recent discoveries, but there may be damage to brain tissue and cause a detectable transient ischemic attack. Therefore, this term is used by some professional associations; They also support the temporary lack of oxygen supply to the tissues of the brain called “ischemic stroke”.
In 40% of cases go to the actual race is shorter episodes later with similar symptoms. This can disorders of memory loss short-term language and discomfort cause a brief paralysis. The “type DRM” also takes only five to ten minutes.
A transient ischemic attack is often a sign of an impending ischemic stroke in the accident in the near future “full” and therefore always be considered the insult as a medical emergency – even if symptoms disappear after a few minutes . In other words, the person shall as soon as possible to the hospital, most placed with the emergency physician.
How to make a diagnosis, the doctor?
If you suspect a stroke, you should as soon as possible to the hospital. There, the doctor asked about symptoms and medical history and risk factors. Other investigations, such as duplex ultrasound, CT or MRI are performed immediately.

How to prevent a stroke?
The best stroke prevention is to minimize avoidable or preventable risk factors. A healthy lifestyle can accomplish much. These include:
Regular exercise and sport
A healthy and balanced diet, rich in fruits and a low proportion of animal origin vegetable fat
The resignation of smoking
Normalization of body mass
reducing the alcohol
Avoid excessive stress
hypertension, dyslipidemia, diabetes and diseases in favor of atherosclerosis and ischemic stroke, and should definitely be treated medically. The same for the relatively frequent atrial fibrillation, stroke can cause a stroke. During atrial fibrillation, the Appeal reduced whole blood is needed; the risk of recurrent stroke – that is, the risk that a new race occurs – can be reduced to 70%. Here antagonists of vitamin K and go. More recently, the “original oral anticoagulants” as dabigatran or rivaroxaban for use
According to studies, an operation to reduce bottlenecks in the carotid artery removed (Karotisthrombendarteriektomie), the risk of major stroke in certain groups of patients, if done within two weeks after a transient ischemic attack.
Because people after an ischemic stroke have a higher risk of recurrent stroke, which are usually drugs to thin the blood to prevent further processed stroke. With antiplatelet call, the risk can be reduced by 30-40%.
