Cerebral infarction has a high mortality and disability rate, and a significant proportion of patients will have symptoms of neurological deficits of varying degrees, resulting in permanent sequelae that affect the quality of life of patients and cause serious social and family burdens. The neurological deficits that still exist six months after the onset of acute cerebral infarction enter the sequelae period, which is called sequelae, and this period has a slower recovery rate and degree and relatively fixed symptoms compared with the recovery period. The sequelae of cerebral infarction vary greatly depending on the location and extent of lesions, mainly manifesting as sensory-motor impairment, language impairment, visual abnormalities and cognitive dysfunction, etc.: 1. Sensory-motor impairment is mainly the presence of hemiplegia (hemiplegia), hemiplegia, numbness of half of the limbs, mouth and eye distortion, etc. It is the most common sequelae, and is also the main dysfunction that causes daily dysfunction and disability of patients. A few patients also experience pain and swelling of the paralyzed limb, which causes significant pain to the patient. 2.Language disorders include aphasia and dysarthria, dysphasia, dysarthria, etc. Dysarthria is often accompanied by dysphagia, choking and coughing of drinking water, etc. 3.Visual abnormalities refer to hemianopia, diplopia caused by external eye muscle paralysis, nystagmus, etc. 4, cognitive dysfunction is manifested as memory loss, confusion, and even abnormal mental behavior, etc. Severe cases eventually develop into vascular dementia. The sequelae of cerebral infarction seriously affect the quality of life of patients, but after active rehabilitation training, it is still possible to restore their motor function and living ability to the maximum extent, and achieve the purpose of self-care and even return to society.
