Facing altered movement coordination? Having problem while talking? Feeling numb on one side of your body? You must not ignore these just like other common ailments as these might be the symptoms of stroke, the second leading cause of death in the whole world. It is found that whatever the causes of stroke are, it affects our Central Nervous System (CNS) the most and ends into permanent neurological disorders, lifelong disabilities, and death. Even if a person survives a stroke, he or she still has 45% possibility of developing a permanent impairment by the attack.
Several risk factors and causes of stroke
Strokes are classified into two major types: Ischemic and Hemorrhagic. When the main artery conducting blood to the brain cells gets blocked and the flow of blood to the brain gets decreased, people suffer from Ischemic stroke. This is the most common form of stroke observed till now. Again, when a hemorrhage or sudden extreme bleeding occurs within the brain or between the brain and the skull, then it is named Hemorrhagic stroke. However, there are some more instances of strokes the reasons of which are still unexplained and therefore cannot be classified correctly.
It is seen that the causes of stroke are common in most of the cases. High blood pressure is the most vital risk factor associated with strokes. It ruptures the blood vessels and thus leads to the formation of blood clots within the brain. High levels of cholesterol can also accelerate the development of blood clots in the brain. Various cardiovascular disorders such as Arterial Fibrillation also stimulate the blood clot formation followed by stroke. Some more significant causes of stroke include diabetes, extreme obesity, old age, habit of smoking etc.
Impact of Stroke
According to doctors, stroke results into the utmost damage of the human body. Both permanent as well as temporary damages occur to the brain cells during this medical emergency. Researches reveal that due to the clot formed within the brain, the cells do not get enough blood supply which leads to an acute oxygen deficiency followed by irreversible damages to the brain. On the other hand, if the brain is shut down temporarily, it usually takes a toll on the regular activities of the individual and consumes long time to restore its functionality. This is why, the patient finds it hard to move, walk, speak, think or even see in a proper way. He or she can also feel acute headaches, vertigo or even sudden weakness on one or both sides of the body.
However, people generally pay no heed to the symptoms of stroke at the initial stages. These stroke warnings or Transient Ischemic Attacks (TIA), given the name Mini Strokes also develop the similar symptoms to those of regular strokes. Though the outcomes of mini strokes neither last for less than 24 hours nor cause any major disabilities, they should not be considered as other minor diseases. Whatever the causes of stroke may be, the impact can always be devastating. Therefore, rapid diagnosis and treatment including prescribed medications and routine checkup of several risk factors such as blood pressure, blood sugar, cholesterol levels etc. can prove the only life saver in such situations.
