Abstract
La apraxia verbal es una alteración de la producción del habla resultante de un daño cerebral adquirido. Durante los últimos diez años ha aumentado el interés por la descripción y comprensión de su naturaleza. Para ello han surgido distintas líneas de estudio que se han centrado en diferentes aspectos entre los que se encuentran las bases neuropatológicas subyacentes, los procesos cognitivo-motores alterados y las conductas verbales observables del trastorno. A lo largo del artículo se presentarán los conceptos más relevantes relacionados con la neuroanatomía, los modelos psicolingüísticos y de control motor y los datos provenientes de análisis perceptivos, acústicos y fisiológicos de la apraxia verbal.

In the last ten years it has enlarged the interest by the description and understanding of its nature. Therefore, different centered lines of study in several aspects have arisen. These are: the neuropathological bases, the processes cognitivo-motors and the verbal conducts of the apraxia of speech. This paper presents relevant concepts of neuroanatomy, psycholingüistic and motor control of speech models, and perceptual, acoustic and physiologic analyses of apraxia of speech.
