Compared with other types of cerebral infarction, the symptoms of lacunar cerebral infarction are relatively mild, and even many patients do not have obvious symptoms. A few minor lacunar cerebral infarctions that do not involve important neural pathways or neurological structures may generally heal spontaneously in 2 weeks to several months. The incidence of lacunar cerebral infarction is quite high, accounting for 20%-30% of cerebral infarction. Common sites include the shell nucleus, caudate nucleus, internal capsule, thalamus, etc., and a few are located in the corona radiata and the subventricular zone of the brain. Some patients do not have any symptoms and are usually found during examination of brain CT or brain magnetic resonance, which is an old lacunar infarction. Although this disease has milder symptoms than other types of cerebral infarction, it has a higher recurrence rate and may still lead to hemiparesis, aphasia, and choking on drinking water if the infarction is located in an important area, such as the brainstem or the internal capsule. The recurrence rate of cavernous cerebral infarction is high and there is a risk of disability, so patients with cavernous cerebral infarction should be actively admitted to the hospital for treatment, searching for risk factors and preventing the occurrence of cavernous cerebral infarction.
