Neurogenic Stuttering: Etiology, Symptomatology, and Treatment

Abstract

Background: Neurogenic stuttering is a subtype of acquired stuttering, and it is characterized by disfluencies associated with acquired brain damage.

Objective: To provide an insight into pathophysiology, symptomatology, differential diagnosis, assessment, and treatment of neurogenic stuttering through a critical review of the literature.

Methods: Studies published during the past and recent years were searched and analyzed on neurogenic stuttering.

Results: Neurogenic stuttering is a complex disorder. The pathophysiological mechanism of neurogenic stuttering is not yet fully understood. It appears with several neurological diseases and conditions, and the use of some drugs. Differential diagnosis of neurogenic and psychogenic stuttering is a challenge for clinicians. Treatment usually requires a joint effort from speech therapists and doctors, most often neurologists.

Conclusion: Although research on neurogenic stuttering can be found in the literature, the complexity of this disorder still requires detailed monitoring and studying to provide the best treatment for patients.
