Why did I suddenly have a cerebral hemorrhage if I don’t smoke or drink?

A patient with moyamoya disease in the outpatient clinic was curious about how he suddenly had a brain hemorrhage since he didn’t smoke or drink, had a regular schedule, and was in great shape. One day, he suddenly felt too weak to stand and couldn’t see clearly. He wanted to sit on the ground to relax, and then he passed out and didn’t know anything. When he woke up, a long time had passed. He found that one side of his limbs was out of control, he couldn’t speak clearly, and he felt dizzy and heavy. He learned that he had a brain hemorrhage. The local hospital diagnosed him with moyamoya disease, and the patient came to Beijing to see me.

Moyamoya disease is a relatively rare cerebrovascular disease. The distal ends of the bilateral internal carotid arteries and their main branches are progressively narrowed and even occluded. During this process of stenosis and occlusion, some compensatory blood vessels grow at the same time. These compensatory blood vessels look like clouds of smoke on cerebral angiography, so they are called moyamoya disease. The main function of these smoke-like blood vessels is to continue to supply blood to the skull instead of the occluded blood vessels.

When hearing the word "smog disease", everyone may subconsciously think that "smog disease" is related to smoking, or even related to smog days, and related to oil fumes, but in fact, "smog disease" has nothing to do with these. The cause of "smog disease" is currently unknown, and it is more considered to be caused by congenital and genetic factors, and has little to do with smoking, smog and oil fumes.

Although smoking and drinking are not the causes of moyamoya disease, they still have a certain impact on patients with moyamoya disease. Smoking inevitably damages blood vessels. The intracranial blood vessel condition of patients with moyamoya disease is worse than that of ordinary people. Coupled with high-risk factors such as smoking, the risk of stroke is relatively higher. For the sake of your own health, it is recommended that everyone quit smoking as much as possible.
