There is often obvious muscle twitching in the affected area. 2. Dysphagia: If the patient belongs to the medulla oblongata type of disease, the damage to the cranial nerves of the latter group may be the main manifestation, such as atrophic tremor of the tongue muscle, dysarthria, dysphagia and other symptoms.
