Can smog affect a child’s intelligence? Smog is a rare abnormal cerebrovascular disease at the base of the skull, the prevalence and incidence of which has been gradually increasing in recent years. It can cause headaches, dizziness, and lack of concentration, or it can lead to hemiplegia, aphasia, or even death! There is no significant gender difference in the incidence of smog in China. In terms of age, children account for about half of the entire age group, most of them are 5 to 10 years old and the youngest is only 8 months old, while the rest of the patients are mainly concentrated in the 30 to 40 age group. Some children start with convulsions or headaches, and headaches can occur months or a year before hemiplegia. Some children start with subarachnoid hemorrhage, with severe headache, vomiting, and inability to bend the neck. Other symptoms include inability to speak, sensory abnormalities, mental disturbances, and mental retardation. Once the ischemic attack occurs, 1.4 million neurons are lost per second, and this state is irreversible. If the IQ is set at 86, then 92% of patients with smog disease have normal IQ within 4 years of onset, 40% of patients have normal IQ 5-9 years after onset, and only 33% of patients have normal IQ 10-15 years after onset. Therefore, smog can affect the intellectual development of children, and if children suffer from smog, they must be treated early so that they can recover as soon as possible. It is important to treat children with smog early so that they can recover as soon as possible and avoid the harm caused by smog. The treatment methods and principles of smog disease: The clinical treatment of smog disease includes direct bypass surgery, indirect bypass surgery and combined vascular bypass surgery. Direct bypass surgery refers to the re-establishment of new blood channels to ensure adequate cerebral blood flow, through direct bypass to make intracranial and extracranial vascular anastomosis, and rapidly improve cerebral blood supply. Indirect bypass surgery, or patching surgery, is the application of muscle and meningeal tissue rich in extracranial blood supply to the surface of the brain inside the skull. To relieve the inadequate blood supply to the intracerebral arteries, the blood flow in the brain is improved by establishing a channel for blood supply from normal blood vessels outside the brain to the brain. With improved blood supply, the need for smoke-like vessels is reduced, thus reducing the patient’s risk of re-occurrence of cerebral ischemia and cerebral hemorrhage. Combined vascular bypass surgery is a combination of direct bypass surgery and indirect bypass surgery, i.e., two surgeries performed in the same operation, and is the most commonly used surgical treatment in clinical practice. It has the advantage of solving the problem of cerebral ischemia at once. The operation is more operable and safe, and the surgical effect is maximized with immediate results. Can smoker’s disease be cured: Smoker’s disease is a chronic progressive disease and there is no curative drug or surgical treatment available. Because combined vascular bypass surgery cannot open the occluded cerebral blood vessels, it can only improve them, so in a strict sense, there is no cure for smoker’s disease. However, combined vascular bypass surgery is to re-establish new blood flow channels and to induce the formation of neovascularization to improve the lack of blood supply to the brain, and with neovascularization, the compensating vessels will not be overly dilated and cause brain hemorrhage, which can lead to death. Therefore, even if the occluded cerebral blood vessels cannot be opened, combined vascular bypass surgery is still possible to treat smog disease. According to a large number of clinical evidence, patients’ symptoms will be improved after the combined bypass surgery. It does not affect the patient’s normal life. Combined vascular bypass surgery is still the only effective treatment for smog. Patients should seek medical advice and arrange for appropriate surgical treatment if they have such a need.
