It is said that the disease is prevented before the disease, both disease prevention change. As time passes by, we are unaware that we have reached middle and old age, due to busy work and exhaustion, although we do not feel the long time, but cerebral atherosclerosis has been formed, the so-called “age is not forgiving”, resulting in the final result of ischemic necrosis of brain tissue, loss of neuronal cells, reduction of brain volume, and the essence of atherosclerosis The essence of atherosclerosis is the formation of plaque, the narrowing of the lumen, the change of the fibrous cap of the plaque and its embedded lipids, and the latent growth of risk factors. With the migration of time, the fibrous cap and the lipid substrate change, the substrate leads to ulceration and even partial tissue necrosis due to pressure ischemia, while the fibrous cap gradually thins under the action of metallic matrix protease because of the change of hemodynamics in its shoulder, and the rupture will be caused by stress or injury, and then platelet aggregation, forming white thrombus, and under the action of fibrinogen, forming red thrombus. Under the action of fibrinogen, a red thrombus is formed, leading to vascular occlusion and acute cerebral infarction. The onset of cerebral infarction is rapid and can catch people off guard. The main symptoms are hemiplegia, numbness of limbs, dizziness, coma, or ataxia, and may leave mild or severe sequelae, resulting in disability, loss of work capacity, and serious loss of quality of life. As the saying goes, the disease comes and goes like a mountain. That’s why prevention is so important!
