People now have a strong sense of health care in order to have a good body. However, there are still many diseases that appear frequently and have far-reaching effects on people’s health. Smoke disease is a very deadly cerebrovascular disease, a lot of people do not know much about smoke disease, especially even its symptoms, so it is easy to delay treatment. What do the symptoms of smog disease look like? Here is a brief introduction. Smoky brain disease is a rare cerebrovascular disease, mainly in the brain abnormal blood vessel network, because the carotid artery and cerebral aorta after narrowing or occlusion caused by some of the side branch of the small blood vessels to supply blood, small blood vessels to supply blood may cause blood vessel dilation shaped like smoke, so it is called smoky brain disease. In the early stage of smog disease, there may not be any special symptoms, the most common is transient ischemic attack, which may cause transient headache, dizziness or limb weakness. However, smog disease is a progressive disease. In the later stages, when the blood vessels supplying blood to the brain gradually narrow and become occluded, in order to compensate for the decrease in blood flow, the capillaries at the base of the brain and the surface layer of the brain will dilate, forming smog-like blood vessels. However, smoky blood vessels are so thin that they cannot maintain the normal blood supply to the brain, and it is very easy for them to rupture or fail to maintain the normal blood supply, which leads to cerebral hemorrhage or cerebral infarction in many patients with smoky brain disease, which is why smoky brain disease must be treated. The symptoms of smog disease are various, the main diagnosis is still through examination, when the above symptoms occur, you can go to the regular hospital through the transcranial Doppler examination, or cerebral angiography to clarify. Cerebral angiography is the gold standard for the diagnosis of smog disease. After the diagnosis of smog disease is confirmed, it can be treated by surgery to improve the blood supply to the brain and reduce the risk of cerebral infarction and cerebral hemorrhage.
