As Stroke (or simply stroke) define the neurological dysfunction is a consequence of impaired perfusion of the brain.

Stroke (stroke) is a disease with worldwide distribution that affects more than 15 million (m.) People each year. Since these individuals about 6 cm. Killed, and 5 cm. Become disabled, while about one person suffers stroke every six seconds. Is a disease which mainly affects the elderly, as 75% of GNI relating ages greater than 65 years, while for every 10 years after 55 years the incidence risk doubles.

Categories of stroke:

The GNI divided into two major categories.

Ischemic stroke in which basic disorder is the interruption of blood circulation in small or larger area of the brain depending on the vessel affected. This category constitutes the vast majority of strokes.

Hemorrhagic strokes are caused by a vessel rupture and blood leaving the brain tissue. This class occurs less frequently and generally has a worse prognosis than the previous category.

Diagnostic points

It is important to know those points that will guide us directly to health care search:

Sudden numbness start (numbness) or weakness of the face, arm or leg (especially if they are on the same side of the body)

Sudden onset of confusion, speech difficulty (lisp, the patient loses his words), or difficulty understanding speech

Sudden onset of visual impairment in one or both eyes

Sudden onset disorder in walking, dizziness, loss of balance or orientation

Sudden onset headache.


Equally important as the diagnosis and treatment is the prevention of stroke by timely interventions to risk factors such as poor diet, obesity, sedentary lifestyle, excessive alcohol consumption and other diseases associated with stroke development (eg diabetes mellitus, hypertension, hyperlipidemia, etc.)

ways prevention of stroke:

Breeding and maintenance of body weight to normal levels

Poor nutrition is a major risk factor for stroke occurrence. Diet rich in fat promotes atherosclerosis vascular and obesity or leading to the development of hypertension.

The Mediterranean diet is the appropriate diet for the prevention of cardiovascular events (stroke, coronary disease, peripheral vascular disease). This diet is based on olive oil, and consists of foods with low fat and rich in fiber such as fresh fruits, vegetables and whole grains. Instead they should avoid foods that contain saturated fatty acids such as red meats, sausages, butters and margarines, yellow cheese and prepared foods such as charmpourgker ready puff pastry products, convenience food and foods fried in palm oil.

Significant interference is and salt intake reduction (<6 g. Of table salt a day, about 1 teaspoon). The salt consumption is directly related to the development of hypertension, a key risk factor for stroke and coronary heart disease.


The increased alcohol consumption related to an increase in blood pressure and clinical cardiac arrhythmia (atrial fibrillation). Alcoholic beverages contain a significant amount of calories and excessive consumption leads to obesity development. As mentioned above all are risk factors for stroke occurrence. Reducing alcohol consumption [Men ≤ 2 drinks Women ≤ 1poto / 24 (1 drink = ethanol 15ml or 360ml of beer or 150ml of wine or 45ml of whiskey)] should be recommended to all.


The healthy diet and exercise combination is a cornerstone in maintaining good physical health and protection from cardiovascular events (eg stroke). Recommended moderate intensity aerobic exercise (cycling, brisk walking, swimming) for 20 to 30 minutes, 4 or 5 times a week. communication is useful in the personal physician of the intensity and duration of exercise for people older than 40 years and those suffering from a disease.


Smoking among other disease states which causes (chronic obstructive lung disease, lung cancer), is associated with failure of the wall of blood vessels and development of cardiovascular events. Specifically smoking doubles the chance of stroke occurrence. It recommended the immediate cessation of smoking at all.

Other disease states

There are some disease states predisposing to stroke occurrence. Such diseases are hypertension, diabetes, hypercholesterolemia, cardiac arrhythmias (mainly atrial fibrillation), certain blood disorders (polyglobulia, thrombocytosis, leukemias), disorders in blood coagulation, vascular lesions (aneurysm, vasculitis etc. .). Their addressing in cooperation with the specialist reduce the risk of stroke development of these diseases.

The IEC is a frequent morbid condition likely to have poor outcomes. Early diagnosis but mainly prevention are the most important weapons in tackling this problem.
