Apraxia verbal : una patología multidimensional [Apraxia of speech : A multidimensional pathology]

Acquired apraxia of speech is an alteration of the production of speech that results of a cerebral wound. 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, psycholinguistic and motor control of speech models, and perceptual, acoustic and physiologic analyses of apraxia of speech.
