Introduction: Neurogenic stuttering is a disorder of neurologic origin in the rhythm of speech during which the patient knows exactly what he wants to say but is unable to because of an involuntary prolongation, cessation or repetition of a sound.
Aim: To assemble new insights regarding the epidemiology, pathophysiology, diagnosis, evaluation and treatment of neurogenic stuttering.
Development: A review of all PubMed and Scopus published articles between January 2000 and September 2016 was performed. Thirty-three publications were analyzed. Neurogenic stuttering is a rare entity whose epidemiological incidence is yet not fully established. It is correlated with several neurological diseases and with several possible localizations within the nervous system. Notwithstanding the recent advances in the understanding of the underlying mechanism, it is not yet possible to establish a single pathophysiological mechanism of neurogenic stuttering. The differential diagnosis is complex and requires the detailed knowledge of other language disorders. The treatment is currently based on specific speech language therapy strategies.
Conclusion: Neurogenic stuttering is a complex disorder which is not fully understood. Additional studies might help to better explain the underlying pathophysiological mechanism and to open doors to novel therapeutic methods.
Title: Tartamudez neurogena: revision de la bibliografia.
Introduccion. La tartamudez neurogena es un trastorno del ritmo de habla de origen neurologico en el cual el paciente sabe perfectamente lo que quiere decir, pero es incapaz de articularlo a causa de la prolongacion, el cese o la repeticion involuntaria de un sonido. Objetivo. Reunir nuevos datos referentes a la epidemiologia, la fisiopatologia, el diagnostico, la evaluacion y el tratamiento de la tartamudez neurogena. Desarrollo. Se llevo a cabo una revision de todos los articulos publicados en PubMed y Scopus entre enero de 2000 y septiembre de 2016. Se examinaron 33 publicaciones. La tartamudez neurogena es una entidad poco frecuente cuya incidencia epidemiologica no se ha definido completamente. Aparece en el marco de diversas enfermedades neurologicas y ligada a distintos lugares del sistema nervioso. A pesar de los avances recientes en el conocimiento del mecanismo subyacente, aun no ha sido posible determinar un unico mecanismo fisiopatologico de este trastorno. El diagnostico diferencial es complejo y requiere un buen conocimiento de otros trastornos del lenguaje. El tratamiento se basa actualmente en terapias logopedicas especificas. Conclusion. La tartamudez neurogena es un trastorno complejo que no se conoce con detalle. Nuevos estudios ayudarian a esclarecer los mecanismos fisiopatologicos que se ocultan tras ella y abririan la puerta a nuevos metodos terapeuticos.
