Nowadays, people are very conscious of health care in order to have a healthy body. However, many diseases still appear frequently and have far-reaching effects on health. Smoke disease is a very deadly cerebrovascular disease, many people do not know much about smoke disease, especially the symptoms of the disease are not known, so it is easy to delay to treatment. What exactly are the early symptoms of smog? Here is a brief introduction. From the medical point of view, the clinical manifestations of smog disease are mainly divided into two categories: hemorrhagic and ischemic, which mostly occur in children under 10 years old and adults around 40 years old. In children, ischemia is the main manifestation, and in adults, the table of bleeding and ischemia is basically similar. We have listed the early symptoms of smog as follows: 1. Headache, dizziness, nausea and vomiting are typical symptoms of smog patients, and most patients start with these symptoms, and some patients also have varying degrees of impaired consciousness. Patients with smog also have varying degrees of mental retardation, such as sensory loss, dysarthria, brain nerve damage, and aphasia. Intracranial hemorrhage, which is a more serious symptom, may occur in 12 to 14 percent of patients with subarachnoid hemorrhage or intraventricular hemorrhage. 4. Some patients may suffer from hemiplegia due to transient ischemic attack in the early stage. And after the attack, patients can usually relieve themselves and do not affect motor function. Smoke disease early symptoms are more manifest, this is a chronic developmental disease, if not timely treatment, and the more serious development will induce cerebral infarction, cerebral hemorrhage and other problems, directly affecting life and health. Therefore, the treatment of smog can not be sloppy. Combined bypass surgery for smog, bypass and patching in one, can effectively improve the patient’s blood supply to the brain, and the post-operative recovery is ideal.
