Brain infarction is a very common type of ischemic cerebrovascular disease, which mainly includes the following types: the most common are lacunar infarction, cerebral thrombosis, and cerebral embolism. The neurological sequelae of lacunar infarction are not particularly typical, and patients may exhibit mild incomplete paralysis of limbs, decreased muscle strength, reduced sensation, or ataxia. Cerebral thrombosis and cerebral embolism often cause extensive brain infarction, where patients typically experience severe limb paralysis, loss of sensation, increased tendon reflexes, positive pathological reflexes, and an inability to care for themselves.
