Stroke is a commonly known disease that is often fatal. A stroke occurs when blood flow to the brain is stopped, by either a blood clot stopping blood from reaching the brain, called an Ischemic stroke, or a blood vessel in the brain bursting or leaking causing internal bleeding in the brain, called a hemorrhagic stroke. When this happens, brain cells are deprived of oxygen and nutrients because the blood cells carrying these essential things are stopped, causing them to die. When the cells in the brain die, sensation or movement in a limb might be cut off and may limit an organism’s abilities. A person with stroke is affected depending on where in the brain the stroke occurs. In other words, symptoms of a stroke may vary. “I was at home. I was alone. I lost all feeling in my right arm, then also in my right leg. At this point I fell over. I realized it was a stroke,” –Fred, a stroke survivor. Some of the most common symptoms indicating that a stroke is occurring include sudden numbness or loss of movement in the limbs on one side of your body or face, sudden vision changes, sudden trouble speaking, sudden confusion, a very intense headache, or sudden balance issues. A stroke is simply acquired when the blood supply to the brain is suspended, but to get to the roots of what causes it, although there is no cure, as damage to the brain is usually irreversible if not cared for quickly, there are different treatments available for both types of stroke. For an ischemic stroke, a tissue called plasminogen activator can be injected into an artery to break up blood clots. For a hemorrhagic stroke a mechanical ventilator can be used to hyperventilate the stroke patient, resulting in a lower and safer blood pressure and decreasing the amou... ... middle of paper ... ...gnals from the brain that were affected. Without functioning nerve cells, the body parts will not know how to function, considering that they aren’t receiving appropriate messages from the brain. The difference between a healthy brain cell and a brain cell affected by stroke is the amount of nutrients and oxygen it receives. A brain cell that is affected by stroke has little to no source of nutrients and oxygen because the artery is clogged, limiting the red blood cells ability to deliver the proper resources to the brain cells. A brain cell that is affected by stroke might look black and small due to the lack of nutrients and oxygen. On the other hand, a healthy brain cell has the service of red blood cells to transfer the fitting amount of nutrients and oxygen to maintain activity inside the cell. A healthy brain cell will most likely look red and full of activity.
