| Abstract | Why does "apraxia of speech (AOS)" remain poorly understood? As well as the controversies over terminology, definition, and symptomatology, the heterogeneity, variants and the evolution of AOS may contribute to the confusion. It is argued that there may be AOS variants without dysprosody. Two cases are described presenting fluent speech resembling "undifferentiated jargon" or recurrent utterances at a time, while slow and scanning speech typical of AOS at the other time. Prosodic alterations may appear and develop in compensation for articulatory problems, influenced by various psychosocial and emotional factors. We should be cautious of using prosodic disturbances as diagnostic criteria of AOS. |
