Typical features of paralysis after internal capsule infarction include hemiparesis on the opposite side of the lesion, hemiplegia, hemiplegia and hemianopsia, which is called the “triple hemiplegia” syndrome. The specific manifestations of paralysis after internal capsule infarction need to be judged according to the area and degree of infarction, which can be divided into two kinds: complete damage and partial damage. 1. Complete damage to the internal capsule: there are a large number of upward and downward nerve conduction bundles in the internal capsule, especially the pyramidal tracts that control and innervate limb movement are highly concentrated in the internal capsule. If the infarction is completely damaged, the typical “three partialities” syndrome, i.e., hemiparesis, hemiplegia, hemiplegia and hemianopsia, will be seen on the side opposite to the infarcted lesion. 2. Partial damage: the internal capsule is divided into the forelimb, knee, and hindlimb, and the nerve conduction bundles in different parts are different. Therefore, hemiparesis, hemiplegia, hemiplegia, hemianopsia, hemianopsia, hemianopsia, hemianopsia, or aphasia can occur in different parts of the infarction, and the infarction can have 1~2 or more symptoms in different degrees. It is recommended that patients with internal capsule infarction paralysis, timely medical consultation, standardized diagnosis and treatment under the guidance of the doctor, to avoid delaying the condition.
