What are the Signs of a Stroke
The stroke could be either ischemic or hemorrhagic. The most common is the ischemic stroke, where the blood vessel in the blood is blocked by blood clot. The other, hemorrhagic is caused by breaking and bleeding of blood vessel inside the brain. The stroke can result in mild to severe affects in the entire body. Paralysis, speaking problems, and emotional problems with thinking are most common after effects of the stroke. Sometimes numbness and pain can also be experienced. Since the brain stops working during a stroke, it is not possible for the patient to understand what is happening? Thus, it is very important as a bystander of such incidents, to identify the symptoms as soon as possible, to save that one life.
There are various symptoms of the stroke, which are discussed below. Symptoms of stroke are apparent because they happen fast. Sudden weakness or numbness of the face, especially on one side of the body is possible symptoms of the stroke. Trouble speaking, Sudden confusion and difficult to understand speech are also lead to stroke. Sudden trouble may happen while seeing from one or both eyes. Dizziness, sudden trouble walking and loss of balance or coordination are also the symptoms of the stroke. Sometimes, sudden severe headache may happen with unknown cause. A sudden interruption of the blood flow to a particular area of the brain leads to the symptoms of the stroke. When such condition arrives, it only takes few seconds for that particular area of brain to stop functioning. Only a little relevant amount of the stroke produces headache. However, the sudden severe headache becomes suspicious for a doctor that there might be internal bleeding is happening inside the brain. For this reason whoever is coming to the emergency department, the department quickly screened for the existence of the blood inside the brain.
The severity of stroke symptoms solely depends on the area of the brain which is affected. Strokes that affect parts of the brain, which are used less in day to day brain activity generally produce mild symptoms. In the same contrast, if stroke affects the part of the brain which is being used at high importance in daily brain activity cause the most noticeable and attenuate symptoms. When a blood vessel is blocked, which carries blood to a particular area of the brain, then only that side would get affected where blood vessel is situated and due to this, symptom appears in the opposite side of the body.
Prevention is always better than cure. There are various risk factors, which increases the risk of a stroke such as diabetes, high blood pressure, heart disease, smoking, and high cholesterol. If you control all these factors, then this will decrease the risk of stroke to a greater extent.
