The human brain is divided into 3 major parts, namely the right and left large brains and the cerebellum in the back, each part has its own function, the right cerebrum will supply the left side of the face, body and limbs and vice versa for the left cerebrum, while the cerebellum has the function of balance and coordination, the brain is an organ that is very sensitive and depends on the supply of oxygen and nutrients from the blood because the brain does not have the ability to store energy reserves, therefore the brain is supplied by 2 arteries (blood vessels that carry blood from the heart) which is large in the front and 1 artery in the back, these arteries will be interconnected at the base of the brain forming a circle of arteries ready to supply blood throughout the brain, the brain needs 50-60cc of blood every minute for every 100grams of tissue brain.
The brain tissue is encased by the lining of the brain consisting of 3 layers, while the brain tissue itself consists of the cortex which is on the outside and the sub cortex which is under the cortex, in this part of the cortex there is a center of movement, sensibility, sublime function (attention, language, memory, object recognition and executive function). The cortex network can function properly when the blood supply to the brain is in good condition.
Understand about stroke
Stroke is a function disorder of the brain, both only part or all parts of the brain caused by interference from the blood flow to the brain. This disruption of blood flow to the brain can be in the form of blockages in the brain's blood vessels or brain blood vessels that break or leak.
Stroke is a very important health problem, 1 in 6 people will experience a stroke, and stroke is the third highest cause of death after cancer and heart disease. Disabilities caused by stroke also have a major impact on the sufferer's personal, social and economic life.
Known as 2 types of strokes, namely stroke bleeding (hemorrhagic) and blockage stroke (infarction / non hemorrhagic), strokes blockage occurs because blood flow in the brain is blocked can occur because blood clots through narrowed blood vessels, while bleeding strokes occur due to blood vessels in the brain ruptured so that blood diverts out of the blood vessels and urges brain tissue. The incidence of blockage stroke is more than that of bleeding strokes.
Both blockage and bleeding strokes cause the supply of brain tissue to be disrupted, so that the nutrients and oxygen needed by brain tissue become reduced or exhausted, the brain tissue will lack energy or die, this is what triggers clinical manifestations in patients.
Disorders experienced by brain tissue will cause the appearance of clinical manifestations, clinical manifestations that occur are sudden due to blockage or rupture of blood vessels is also sudden. The manifestations experienced can be one or more of the following manifestations:
1. Impaired consciousness
A person who experiences a stroke can suddenly experience a disturbance of consciousness, starting to look sleepy until it cannot be awakened.
2. Sublime function disorders
Sublime functions are intellectual functions, which include attention, language, memory (memory), visuospatial (recognition of form and space) and executives (Decision making), Disturbance of sublime functions that occur due to stroke can affect 1 or more sublime functions above.
3. Weakness half body
This complaint is the most frequent and most remembered by the community, namely the weakness of half of the body that is sudden, weakness experienced has different degrees ranging from mild to unable to move at all
4. Half-body disturbance
The taste disorder can be various, but it is half the body, for example thick, thick, tingling, needles, half body pain
5. Pelo or perot
Pelo and perot is also a frequent symptom, weakness that occurs in the facial muscles side-by-side will cause the face to be attracted to the healthy side, this causes the face to appear perot as well as the weakness of the tongue muscles so that patients complain of pelo / slurred / celat
6. Spin dizziness or groggy
Spinning dizziness or nggliyer (feeling of floating, light, swaying) can be experienced both as the beginning of a stroke because blood flow in the cerebellum begins to decrease or because a stroke has occurred in the brain.
7. Sudden blindness
Sudden blindness is one of the manifestations of stroke, if there is a blood vessel disorder in the large brain in the back
Keep in mind that complaints - complaints that arise because of a stroke are always sudden or sudden, the complaint can only occur less than 24 hours or stay more than 7 days. If the complaint appears missing within 24 hours then what happens is a cursory stroke or called TIA (Transient Ischemic Atttack). TIA is a risk factor for stroke because it must be treated immediately.
The United States Government introduces its citizens to signs of stroke that must be recognized so that they can immediately ask for help, known as F.A.S.T (Face. Arm. Speech. Time)
Face: recognize the presence of perot on the face
Arm: Half of the body and limbs are difficult to move
Speech: Talk to pelo / cedhal / celat
Time: Immediately seek medical help
The results of stroke therapy are very dependent on time, which is meant here is the time from the onset of the attack to getting medical help (golden period), therefore if there are signs that as above sufferers must immediately be taken to the emergency department.
