Cerebral infarction is a generic and common name for acute cerebrovascular disease, which is a group of diseases with ischemic and hemorrhagic brain injury as the main clinical manifestations and has a very high death and disability rate. Brain cells are non-renewable tissues that cannot be regenerated after damage to their core, and then there are certain sequelae. The most common ones are crooked mouth, unclear speech, drooling, hemiplegia, and excretory dysfunction. The death of brain cells will lead to the loss of the functions innervated by these brain cells, and if the brain cells innervating the arms of the upper limbs die, the movement of the upper limbs will be lost. The sequelae of cerebral infarction are mainly related to the site of infarction, and the symptoms mainly include hemiparesis (hemiplegia), hemiplegia, limb numbness, hemianopia, aphasia. Or crossed paresis, crossed sensory disorder, external eye muscle paralysis, nystagmus, difficulty in constructing speech, language disorder, memory loss, mouth and eye distortion, difficulty in swallowing, choking and choking, dizziness and headache. Some people with 3 years of cerebral infarction have crooked mouths, which are indeed related to the sequelae of cerebral infarction. For the legacy of cerebral infarction, we should pay attention to do the following: 1, pay attention to the dietary conditioning, light diet, low salt and low fat, control salt intake, avoid eating fried food, swallowing dysfunction, it is recommended that long-term nasal feeding diet, to avoid accidental aspiration caused by feeding through the mouth, resulting in lung infection; 2, for the limb dysfunction, it is recommended that long-term acupuncture physiotherapy, massage, to prevent limb stiffness and reduce the daily life 3. For those who are bedridden for a long time, attention should be paid to diet, strengthening protein intake to ensure nutrition, increasing body resistance, and paying attention to regular turning and back tapping to prevent aspiration pneumonia and pressure sores. Rehabilitation training for stroke is crucial and is the key treatment for the sequelae of cerebral infarction, including functional movement of the limbs, swallowing function training, language function training, etc. Rehabilitation training is relatively complex and the rehabilitation training period is relatively long, which can be extended to one year after cerebral infarction, but the earlier the intervention of rehabilitation training, the better the effect.
