Stroke is also called stroke, there are two cases of dysphagia caused by stroke, one is true bulbar palsy, the other is pseudo-bulbar palsy caused by cerebral infarction, which needs to be treated according to the results of EEG, MRI and other examinations. 1. True bulbar palsy: after the brainstem lesion, the nerves innervating the muscles of pharynx and throat are damaged, which can cause obvious atrophy of the muscles related to swallowing, and the clinical manifestation is the delayed paralysis of tongue, soft palate and pharyngeal muscles, and the swallowing reflex is almost disappeared, which makes it very easy for swallowing by mistake. It is difficult to treat, and the possibility of long-term nasal feeding diet is very high. 2. Pseudobulbar palsy: pseudobulbar palsy caused by cerebral infarction refers to the incoordination of swallowing muscles due to cortical dysfunction, clinical manifestations are similar to those of true bulbar palsy, but swallowing disorders are light, dysarthria is heavy, and pharyngeal reflex exists. If you have difficulty swallowing after a stroke, we recommend that you seek medical attention to identify the cause and then target treatment.
