Stroke : A Stroke Survivor

Stroke Stroke is a commonly known disease that is often fatal. This cellular disease occurs when blood flow to the brain is interrupted by either a blood clot halting the progress of blood cells in an artery, 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. Stroke is simply acquired when the blood supply to the brain is suspended, but to get to the roots of what causes it, a stroke is triggered by the slowly forming plaque buildup over time. The plaque is made up of calcium, fat, cholesterol, cellular waste, and fibrin, a material involved in blood clotting. The plaque existing in an artery can grow big enough to block the supply of blood to the brain, resulting in a stroke. A stroke can also be caused by high blood pressure breaking a blood vessel in the brain causing internal bleeding. ... ... middle of paper ... ...n infectious nor a genetic disease, but instead, a disease that affects the function of cells in the brain. Although stroke is a cellular disease and cannot be transmitted or inherited, it can be more likely to occur in an individual if it has occurred in ancestors. This is possible because traits such as high cholesterol levels or diabetes can be passed down genetically. CADASIL is a genetic disorder that is caused by a mutation in the NOTCH3 gene on chromosome 19 that affects blood flow in small blood vessels in the brain. This damages the vessel walls. While stroke cannot be directly passed down from your parents, a disease such as CADASIL can encourage a rupture in a brain vessel, which could easily evolve into a dangerous hemorrhagic stroke. Although genetic abnormalities can increase the risk of a stroke, it can always be provided by maintaining proper health.
