Great brain or cerebrum, composed of two hemispheres, left and right. In normal human brain generally side of this great growing more rapidly than the other hemisphere (perhaps as a backup). In people with left-handed (deft left hand) the right hemisphere of the brain is more developed than the left hemisphere, in contrast to the normal people left cerebral hemisphere dominant. If there is damage to one hemisphere of the brain then their counterparts in other parts of the cerebrum can replace the function by training. Big brain function is to manage the front of the eye movement and pupil of the eye (the child’s eyes), regulate muscle movement to speak, the ability to associate.
The side set the listening, the upper and middle to muscle movement, body, legs and hands, and taste. The back to the vision and the ability to associate vision. Depending on the location of major brain damage occurs in paralysis or disruption in the body that regulated. When damage occurs in the brain that regulate muscle times, there was paralysis of the legs, and so on.
Small brain or cerebellum, is part of the brain responsible for coordination of muscle movement, minor brain damage resulting in disturbance of coordination of movement. The last part is the brain stem, here lies the vital settings for the defense of people’s lives, damage to brain stem death.
Stroke, or better known as paralysis or piansui, is a collection of symptoms caused by neurological brain disorders that persist for more than 24 hours, usually caused by disorders of blood circulation to the brain. Incidence of stroke is greater in men than against women. Risk factors for stroke are high blood pressure, high blood fat levels (cholesterol), diabetes, smokers, alcohol drinkers, and users of birth-control pills.
According to the cause then the stroke can be classified into two, stroke, ischemic (lack of blood supply) and stroke due to bleeding in the brain.
Ischemic stroke caused by blood vessel blockage, or narrowing of blood vessels. When a blockage or narrowing of short duration (several minutes) then called TIA (transient ischemic attack). When the prolonged ischemic stroke, with symptoms according to the area of damage that occurs in the brain (areas that do not have blood)
Haemorrhagic stroke is caused by the rupture of one or more blood vessels in the brain. Symptoms that arise depending on the location of the bleeding. Bleeding that occurs outside the lining of the brain, as generally happens in an accident, have surgery. When not in surgery to remove blood, brain tissue will be damaged because of pressure by the accumulated blood clot between the skull and brain. Minor bleeding that can last a long time, until symptoms occur may be one or a few days after the accident. Bleeding that occurs in the room between the membranes surrounding the brain and brain tissue usually caused by rupture of the artery, symptoms occur quickly. This person needed to have surgery to remove blood, if not, there will be damage to brain tissue that can not be restored. The person will lose consciousness (coma), and if left to die.
Bleeding that occurs within the brain tissue usually occurs because of high blood pressure. The network will be driven around the location of bleeding and lead to tissue. The lack of blood supply, the symptoms that arise depending on the area of bleeding and its site. Symptoms may include paralysis when mild to severe and destructive death if vital parts of the brain.
The action is the prevention of stroke, quit smoking, stop drinking alcohol, treat high blood pressure, adjust blood sugar and blood fat levels strived for in the normal range through diet, healthy living habits, and taking medication if necessary.
No first aid measures that can be done by the laity in the incidence of stroke to prevent damage or reduce the symptoms of severe disability due to stroke. Appropriate action is to quickly bring the patient to the hospital emergency units, especially hospitals that have stroke units.
