Healthy life is what everyone wants to have, but very often it is because some diseases are hereditary, so when patients have some diseases, they may be more worried about the hereditary nature of the disease, we all know that smog disease is very harmful to people’s bodies, so smog disease in the end will be hereditary? Smoke disease is a rare cerebrovascular disease, originated in Japan, from the first discovery of smoke disease to now has been more than half a century, but for the pathogenesis of smoke disease is still not clear, the science has not been finalized. It is only known that it is due to the slow thickening of the endothelium of the middle cerebral artery at the beginning of the artery, the lumen of the artery is gradually narrowed to the point of occlusion, which leads to the obstruction of the blood supply to the brain easily leading to cerebral infarction and cerebral hemorrhage, which is very damaging to the human body. Smoke disease after some research does have a genetic predisposition, and there is a certain family aggregation, for example, the patient has symptoms to the hospital checkup found to be smoke disease, and then said that his children also have the same symptoms, through the examination found that his children are also smoke disease. So people with a family history of smog disease, if there is a headache, dizziness, vomiting, limb weakness, memory loss, aphasia, hemianopsia and other symptoms, you should go to the hospital as soon as possible to conduct relevant checks, but there is no need to worry about anxiety, the possibility of heredity is not large.
