Symptoms of a stroke may include:
- Sudden loss of coordination or problems with balance
- Paralysis of a leg, arm or one side of the face
- Trouble speaking or understanding speech
- Numbness, weakness or dizziness
- Eye or vision problems, such as blurred or double vision
- Severe, sudden headache without apparent cause
There are two main types of strokes:
- Ischemic Stroke — This type of stroke accounts for the majority of stroke cases. When the blood supply to a part of the brain becomes blocked, it prevents oxygen and nutrients from reaching brain cells. Within a few minutes, these cells may begin to die. The underlying cause for this type of obstruction is usually atherosclerosis, a condition in which plaque or fatty deposits within the wall of the arteries in the brain and neck can lead to obstruction or narrowing. These fatty deposits can cause cerebral thrombosis or cerebral embolism. With a cerebral thrombosis, a blood clot forms within the blood vessel. Cerebral embolisms are clots that can form at another location in the circulatory system, break loose from an artery wall or from the inside lining of the heart, travel through the brain’s blood vessels and can lodge in an artery in the brain.
- Hermorrhagic Stroke — With hemorrhagic stroke a blood vessel within the brain leaks or ruptures and bleeds into the surrounding brain tissue. The blood can accumulate and exert pressure on the surrounding tissue. High blood pressure is a common cause of intracerebral hemorrhage. In a subarachnoid hemorrhage, blood leaks under the lining of the brain. This is often caused by a small bubble on an artery known as an aneurysm.
If you are experiencing any symptoms of stroke, it is best go to a doctor or hospital immediately by dialing 995 for emergency ambulance. Time is of the essence and sift medical attention may make a difference to the treatment.
