Hemiplegia, also known as hemiparesis, refers to the movement disorder of one side of the upper and lower limbs and the lower part of the facial muscles, which is mainly seen in traumatic brain injuries, brain tumors, intracranial infections and other brain lesions, and also seen in spinal cord lesions, multiple sclerosis, and motor neuron disease and other disorders, as follows.
1. Brain lesions: mainly cerebrovascular lesions, followed by traumatic brain injury, and other brain occupying lesions and infections; for example, cerebral hemorrhage, cerebral infarction, cerebral contusion, brain tumors, encephalitis and other diseases.
2. Spinal cord lesions: mostly caused by semi-transverse injury of the cervical cord in the high cervical segment, commonly seen in cerebrospinal inflammation and other diseases.
3. Others: for example, demyelinating diseases (common in lesions such as multiple sclerosis), myogenic hemiparesis (can be seen occasionally on one side in hypokalemic periodic paralysis), lower motor neuron hemiparesis (seen in acute infectious polyneuritis with hemiplegic motor neuron disease).
There are many causes of hemiplegia, and other causes cannot be ruled out. If there are any of the above causes or symptoms of hemiplegia, you should consult a doctor promptly for targeted treatment.
