- 交叉性瘫痪是一侧脑干病损，由于损害已交叉的皮质脑干束纤维或颅神经与核，和未交叉的皮质脊髓束，产生交叉性瘫痪；即病灶侧的周围性脑神经麻痹和对侧肢体的中枢性偏瘫。病变同侧脑神经的周围性麻痹，对侧肢体中枢性瘫痪和偏身感觉障碍，是由于一侧运动和感觉神经核传出及传入神经纤维受到损害所致。建议及时治疗脑干梗塞，输血塞通等药物治疗。
Cross palsy is a brainstem lesion. Crossed paralysis occurs due to damage to the cortical brainstem tract fibers or cranial nerves and nuclei that have crossed, and the uncrossed corticospinal tract; that is, peripheral cranial nerve palsy on the side of the lesion and Central hemiplegia of the contralateral limb. Peripheral paralysis of the cranial nerve on the same side of the disease, central paralysis of the contralateral limb, and sensory disturbances on the side of the body are caused by damage to the motor and sensory nuclei and the afferent nerve fibers on one side. It is recommended to treat brainstem infarction in time, blood transfusion plug and other drugs.
2.假性球麻痹：双侧皮质延髓束损害引起运动颅神经的上运动神经元性瘫痪
真性球麻痹：延髓中的运动颅神经核或颅神经的损害，属于下运动神经元瘫痪
Pseudobulbar palsy: damage to the bilateral cortical medulla oblongata leads to paralysis of the upper motor neuron of the motor cranial nerve.
Pseudobulbar palsy: damage to the motor cranial nerve nucleus or cranial nerve in the medulla oblongata, belonging to lower motor neuron paralysis
