A stroke happens when brain cells begin to die resulting in brain damage. Arteries carry blood from the heart and distribute it throughout your body. Blood clots block this flow of blood to the brain and reduce the blood flow to the brain.
Those abilities that are controlled by the area of the brain affected by the blood clot can result in life style changes. Damage most often involves speech, memory and movement. The effect is dependent upon where the event occurs and by how long the area is deprived of blood flow.
Often someone who experiences a minor episode may only have minor problems that could result in weakness in an arm or leg. Others, who experience more significant damage to the brain, might be paralyzed, perhaps on one side. Others may lose the ability to speak.
In many cases people recover fully from any damage. However it is reported that more than 66 percent who suffer from one will often have some form of disability.
SYMPTOMS OF A STROKE
It does not take long for the symptoms to be evident. Most often with a very few minutes the brain cells will begin to die and common symptoms will begin to emerge. The most common would be:
– dizziness accompanied by trouble walking and having a loss of balance and coordination
– problems with speaking clearly
– vision issues such as blurring or double vision
– weakness or numbing on one side of the body, or possible paralysis
– headache onset very suddenly and very severe
When there is a temporary interruption of blood flow to an area in the brain a preliminary sign of a stroke could occur. This is called a transient ischemic attack (TIA). The symptoms are very similar; however they only last for a short period of time. TIA’s do not leave any noticeable damage. They do serve as a warning that something is occurring in the blood stream and one should seek medical attention to determine the cause.
It is a medical emergency, and anyone suspected of having one should be taken to a hospital immediately so that tests can be run and the correct treatment can be provided as quickly as possible.
