According to clinical studies, smog is mainly found in two groups of people, adults over 40 years old and children under 10 years old, and other age groups may also occur, but the incidence is lower. Adults are usually easy to detect when symptoms appear and seek medical attention in a timely manner. In children, it is easy for parents to ignore the symptoms because of their young age and sometimes unclear expressions, so parents should usually learn more about the clinical manifestations of childhood smog. What are the symptoms of smog in children? When children have smog, the symptoms are usually ischemic in nature. When the formation rate of smoke vessels is lower than the normal vessel occlusion rate, the formation rate of compensatory vessels is slower, which can easily cause cerebral infarction. Also due to long-term ischemia, dizziness and headache symptoms may occur frequently, and some patients also have symptoms such as decreased intelligence, memory loss, poor learning ability, abnormal vision, and seizures. This shows that the symptoms of smog in children are complex and varied. Can smog in children be cured? Most experts still agree with surgery as a treatment option for smog. Some anticoagulants or antiplatelet drugs can relieve the ischemic symptoms to some extent, but they cannot slow or stop the disease process. Some parents ask whether children with mild smog can be treated without surgery. After clinical studies and summaries, it is found that patients can achieve the desired results and their symptoms can be greatly improved after undergoing surgical procedures. Therefore, the right approach for parents is to detect and diagnose smog in children as early as possible. Most children who are detected early and treated surgically can return to normal life, but if treatment is delayed and cerebral hemorrhage or cerebral infarction occurs, it may lead to hemiplegia, disability, and in severe cases, life threatening. After continuous analysis and research of treatment cases, it is found that traditional bypass surgery or patching is still defective in the treatment of smog disease, while combined with vascular bypass surgery, significant results can be achieved.
