Cerebral stroke occur when the cerebral artery is blocked, thereby forming a clot in the cerebral artery and preventing the blood from reaching to other parts of the body or when the artery ruptures and bleeds into brain tissue. Very high BP causes the artery to rupture. This leads to bleeding from the artery in to the tissues of the brain. Atherosclerosis leads to narrowing and hardening of the arteries. Many a times, a clot in the heart or from the main artery is displaced and reached the brain. This hampers the blood supply. When the insufficiency of blood supply lasts a couple of minutes or bleeding from the arteries can result in the death of brain cells in that area.
Cerebral stroke could occur due to various reasons. The major amongst them are persistent high blood pressure, very high cholesterol levels, weak heart, bleeding disorders, certain medications which are used prevent blood clots may release a clot from heart to the brain and lead to cerebral stroke, liver disease, diabetes, smoking, excessive consumption of alcohol, drugs and AIDs are among factors that can cause a stroke.
The symptoms of a stroke may appear suddenly. It depends upon the artery affected and the manner in which the supply of blood is affected and the part of the brain which is affected. There could be various symptoms of cerebral stroke. Vision may be impaired, eye movements may be affected, speech may be hampered, other senses of the body may be affected, it could lead to paralyses of one side of the body or a part of the body may be affected. Often stroke could lead to confusion, headache, nausea, dizziness, deafness, stiffness, fits and loss of control of bladder, loss of memory, blurred or blabbered speech. A stroke could result in coma. MRI and CT scans can help in identifying as to which part of the brain is affected. A person has to be taken to the hospital without slightest delay in case of a stroke. Call for an ambulance. Make the person lie down in a comfortable position, and ensure that he or she is able to breathe freely.
Treatment is given to reduce the swelling in brain and the harm caused to the brain. Some of the body impairment may be life long. Physiotherapy is effective and the patient is required to continue exercises for months together. Medicines are given to reduce the chances of further strokes. The patient may require speech therapy. Regular check ups are required post recovery. The patient should maintain a diet control. Avoid deep fried foods, exercise regularly, reduce weight in case of over weight people, and take medicines in the prescribed doses at the prescribed intervals.
Blood Pressure should be monitored regularly. Cholesterol reports should be taken once in three months and shown to the doctor. To prevent strokes, eat a balanced diet. If you are diabetic, eat a sugar free diet. Go low on salt to keep BP in check. Avoid pickles and papads, as they are very high in salt content.
