Dysphonia
View through CrossRef
Dysfunction of the vocal cords (dysphonia) is not as common a manifestation of neuromuscular disorders as dysarthria. It is typically seen in central diseases such as Parkinson disease and spasmodic dysphonia. Certain muscle and nerve disorders affect the vocal cords, but in these cases other features of these diseases make the diagnosis easy. Myasthenia may present with only intermittent hoarseness early in the course of the disease. Consultation with an ear, nose, and throat (ENT) specialist is recommended to characterize the type of cords pathology. Hysterical hoarseness and weakness are not an unusual presentation to the neuromuscular clinics but again, they do not occur in isolation and other psychogenic symptoms such as give way weakness and functional gait disorder often lead to the right diagnosis.
