The prognosis of cerebral infarction depends on the size and location of the infarction. In small cerebral infarcts, such as infarcts in the radiocoronal area, the clinical symptoms and signs are often mild, and after active treatment, most of them can be cured clinically and usually do not leave sequelae. For patients with large cerebral infarcts, brainstem infarcts and basal ganglia infarcts, the clinical manifestations are often more severe, and most of them can usually have sequelae. The brainstem is the life center of the body, and even small infarct foci can be life-threatening. The basal ganglia region is where the nerve fibers are concentrated, and if the lesion invades the internal capsule, patients can develop hemiparesis, hemianopia, and hemianesthesia, and most patients can have sequelae. In patients with massive cerebral infarction, cerebral edema, increased intracranial pressure, and brain herniation can also occur, even leading to death.
