Cerebral infarction is a major disease of the nervous system. Cerebral infarction is caused by atherosclerosis of the brain or some other causes that interrupt the blood supply to the brain, resulting in ischemia, hypoxia and necrosis of brain cells. Patients may experience symptoms of neurological deficits, such as weakness of the lateral limbs, numbness of the lateral body, clumsy speech, skewed walking, choking and coughing, etc. The diagnosis can be confirmed by CT or MRI examination of the head, and symptomatic treatment such as antiplatelet aggregation, activation of blood circulation and improvement of circulation can be given. Cerebral infarction is a disease with a high disability rate, and patients can have some sequelae, and in serious cases, they can become unable to take care of themselves and bedridden, etc. Some patients with severe choking and coughing need long-term gastric tube feeding, which has a serious impact on the quality of life of patients, so cerebral infarction is a major disease of the nervous system.
