The basal ganglia region of the brain is an important area for controlling the movement of human hands and feet, and cerebral infarction in the basal ganglia region can often lead to more serious neurological deficits, including weakness and numbness of the limbs, as well as slurred speech and facial paralysis. However, the exact severity of the disease still needs to be assessed according to the patient’s age, underlying disease, the extent of the infarction, and cerebrovascular conditions. If the patient is younger, has no serious underlying disease, and the infarction is small in extent, and is a lacunar cerebral infarction of the basal ganglia, the patient’s clinical symptoms are generally milder and the prognosis is better. If the patient is older, has a larger infarct in the basal ganglia, and has poor vascular conditions, such as severe stenosis or occlusion of large vessels, the patient’s condition will be severe, with a high risk of recurrent infarction and a poorer prognosis.
