How long it takes to recover swallowing function after brainstem infarction varies from person to person, depending on the severity of the lesion, and there are individual differences in whether recovery is possible. There are two types of swallowing dysfunction after brainstem infarction, one is bilateral cerebral hemispheric multiple infarction, resulting in bilateral cortical brainstem bundle dysfunction, i.e. pseudo-bulbar palsy. The other is when the cerebral vessels supplying the medulla oblongata become occluded and circulatory ischemia causes ball palsy in the patient. When the symptoms of ischemia occur, but not completely blocked blood flow, the part of the cells that are not completely dead will have a natural recovery process as the cerebrovascular disease time is prolonged. In addition, the nervous system has plasticity and will utilize other functional areas to compensate for the function of the damaged area. If the cells and brain regions function well to compensate for the function of the lesion, the patient’s swallowing function will be restored. If it fails to compensate, the patient’s swallowing function will not recover. If the patient has obvious dysphagia, a nasogastric tube or nasoenteric tube should be left in place as soon as possible to avoid choking and aspiration. Nutritional nerve drugs such as B vitamins, methylcobalamin and cytarabine should also be given actively to promote the recovery of swallowing function. Swallowing function can also be rehabilitated with the help of swallowing speech therapy instrument during the recovery period. Patients with swallowing dysfunction in brainstem infarction should ask the doctor to evaluate the swallowing function in time, and actively carry out treatment and rehabilitation.
