A stroke is a “brain attack. It can certainly take place with anyone most of the time. It happens when ever blood flow to an area of human brain is cut-off. When an attack happens, brain cells are short of oxygen and then they begin to die out. Whenever human brain cells die throughout a heart stroke, capabilities controlled by that area of the human brain like memories and muscular control are lost.
The way a person is being affected by their stroke depends upon exactly where the stroke occurs in the brain and how much the human brain is affected (damaged). Take for example; a person who had a small heart stroke may only have less serious problems such as temporary body weakness of an arm or leg. People who have larger strokes might be permanently paralyzed in one area of their entire body or lose their ability to speak. Many people recover entirely from strokes, however more than 2/3 of survivors will face some form of disability.
A stroke is an unexpected phenomenon that happens whenever the supply of blood to a part of the human brain is disrupted or when a blood vessel in the brain bursts, spilling the blood into the gaps surrounding human brain cells. Endangering factors involve things such as having high blood pressure levels, the smoking habit, and having a family history of heart stroke. Signs and Symptoms of a Stroke typically take place suddenly and can include things like confusion, nausea, extreme headache, and numbness or weakness in the arms and legs or face. Proper treatment can include medications, surgical operation, and rehabilitation.
A stroke is a sudden encounter that might affect awareness, sensation, and movement, which results from a clogging or even rupture of the blood vessel in the human brain. It can cause signs or symptoms that survive for at least twenty-four hours. A heart stroke (known medically as a cerebrovascular accident or CVA) will occur when the blood supply to section of the human brain is unexpectedly disrupted or when a blood vessel in the brain bursts, spilling blood into the areas encircling brain cells. Brain cells stop working as they do not get oxygen and nutrients from the blood or there is sudden bleeding into or around the brain.
Types of Stroke
There are two main types of stroke – ischemic and hemorrhagic.
1. Ischemic: Ischemic refers to a reduced blood flow as well as oxygen supply to a part of the body system. It is caused by blood clot in an artery, which blocks the transmission of blood. This occurs in about 7 in 10 cases.
The blood clot generally forms within the artery itself. This commonly happens over a patch of fatty material known as atheroma. Atheroma is usually termed furring or hardening of the arteries. Smaller patches of atheroma form inside of arteries in most elder people. If a patch of atheroma will become thick, it can trigger the blood to clot.
In certain cases, the blood clot forms in an alternative part of the body and then transmit in the bloodstream – this is called an embolus. The most commonly encountered example is a blood clot which forms in a heart chamber because of irregular turbulent blood flow. This can occur in a condition called atrial fibrillation. The blood clot is then transmitted in the bloodstream until it gets stuck in an artery in the brain.
There are other rare causes of ischemic stroke.
2. Hemorrhagic: An intracerebral hemorrhage will occur whenever the blood vessel bursts inside the human brain. The blood then spills into the surrounding brain tissues. This may cause the damaged brain cells to lose their oxygen supply. They get damaged or die. Such things happen in about 1 in 10 strokes. A subarachnoid hemorrhage occurs when a blood vessel bursts in the subarachnoid space. It is the narrow space between the brain and the skull. This space is usually filled with a fluid known as the cerebrospinal fluid. Almost 1 stroke in 20 is due to a subarachnoid hemorrhage.
Early Warning Signs and Symptoms of Stroke
- Suddenly weakness or numbness of the face, arm or leg, generally on one side of the body.
- Sudden confusion, trouble in understanding, interpreting or speaking.
- Blurred vision of eyes.
- Trouble in walking, loss of balance or control.
- Severe headache.
Experts have suggested a key word to remember signs of strokes such as “BEFAST”, which expands into
- B- Balance: A sudden loss in co-ordination of legs, which will not allow you to walk straight.
- E- Eyes: Double vision, or blurred vision and blindness in one eye.
- F- Face dropping: Numbness on one side of face or uneven smile.
- A- Arm weakness: Weakness in one arm, unable to move hands.
- S- Speech difficulty: Difficulty in speaking and understanding; slurred speech.
- T- Time to call doctor: If you experience any of the above symptoms then it’s time for you to seek immediate medical expertise.
One should not sit at home, if one experiences the above early signs of stroke. So just remember BEFAST whenever you are trying to determine if you or someone else is having a mild or full stroke.
What is Mild Stroke?
A mild (Mini) stroke is an ordinary type of heart stroke and thus its neurological symptoms and signs usually do not last long so they totally withdraw. Despite this, even a mild stroke needs to be taken very seriously since it can represent formation to a much more serious situation, an actual stroke. In a mild stroke, a blood clot merely temporary stops the flow of blood to a certain part of the human brain. Once the blood flow is restored all the damaged features are restored. Medical name for mild stroke is transitory ischemic attack. The symptoms and signs of mild stroke usually depend upon the part of the brain that is damaged and most of them may even stay unacknowledged. The most significant symptoms and signs occur when areas of the human brain we commonly and regularly use are damaged.
This medical condition is associated with various aspects for example age, family medical record, high blood pressure levels, cardiovascular disease, elevated levels of cholesterol, sickle cell anemia etc. Smoking, a diet rich in fatty foods as well as being overweight are also risk factors for mild stroke.
Symptoms and Signs of Mild Stroke
Following are the most common symptoms of mild stroke:
- Pain in chest
- Blurred vision
- Loss of balance and co-ordination
- Slurred speech
- Weakness in one hand and leg
- Numbness on the face
- Uneven smile
- Muscle stiffness
- Memory loss
- Difficulty in swallowing
Call your doctor if you experience the above symptoms and signs of mild stroke.
Strokes Symptoms and Signs in Men
For men and women, stroke is recognized by an inability to speak or understand speech, a strained expression, numbness on face and confusion. Someone who’s having a stroke may also have trouble in talking or understanding conversation. There are no stroke symptoms unique to men. Most common symptoms are BEFAST as we talked earlier.
Signs and Symptoms of Strokes in Women
Women are less likely to receive a Tissue Plasminogen Activator (TPA) meant to break up blood clots. This is an important development because the most common type of stroke is caused a blood clot reaching the brain. In short, women tend to have “vaguer” stroke symptoms. In turn, they are not always treated as a sign of stroke which leads doctors to avoid the use of a tissue plasminogen activator.
Although men are more likely to have a stroke, women have a higher lifetime risk of stroke. Women are also more likely to die from a stroke. Women face a greater chance of having a stroke for many reasons. Women live longer than men. Women experience more stress than men. Women are more likely to have high blood pressure than men. Pregnancy and birth control also increase a woman’s risk of stroke. The stroke symptoms for women include:
- Coordination problems
- Shortness of Breath
- Pain (arms, legs, face)
- Chest Pain
Because these symptoms are unique to women, it may be difficult to immediately connect them to stroke. This can delay treatment, causing severe injury, permanent disability, or death.
More Info on Strokes Signs and Symptoms
A heart stroke causes damage to the human brain. A very common cause of stroke is a blood clot that forms in a brain blood vessel (artery). Instant treatment can include a clot-busting medication to dissolve the blood clot. Some other treatments include things like medication to help reduce risk factors for further strokes. Rehabilitation is a major part of treatment. Disability following a heart stroke depends upon factors such as the part of the brain affected, exactly how instantly treatment was given and the scope of the harm to the brain.
The supply of blood to the human brain comes mainly from four blood vessels (arteries) – the right and left carotid arteries along with the right and left vertebrobasilar arteries. These branches into different small arteries which supply the blood to all the areas of the human brain. The area of brain affected and the extent of the damage depend upon which blood vessel is damaged
For example, if you cut the supply of blood from a main carotid artery in that case a wide area of your brain is affected; this can cause serious symptoms or death. In contrast, if a smaller branch artery is affected then only a smaller area of brain is affected which can cause comparatively minor signs or symptoms of Strokes.
