Remarkable progress has been made over the past two decades in expanding our understanding of the behavioral, peripheral physiologic, and central neurophysiologic bases of stuttering in early childhood. It is clear that stuttering is a neurodevelopmental disorder characterized by atypical development of speech motor planning and execution networks. The speech motor system must interact in complex ways with neural systems mediating language and other cognitive and emotional processes. During the time when stuttering typically appears and follows its path to either recovery or persistence, all of these neurobehavioral systems are undergoing rapid and dramatic developmental changes. We summarize our current understanding of the various developmental trajectories relevant for the understanding of stuttering in early childhood. We also present theoretical and experimental approaches that we believe will be optimal for even more rapid progress toward developing better and more targeted treatment for stuttering in the preschool children who are more likely to persist in stuttering.
在过去二十年里,我们对幼儿口吃的行为、外周生理和中枢神经生理基础的理解取得了显著进展。很明显,口吃是一种神经发育障碍,其特征是言语运动计划和执行网络的非典型发育。言语运动系统必须以复杂的方式与介导语言及其他认知和情感过程的神经系统相互作用。在口吃通常出现并走向恢复或持续的时期,所有这些神经行为系统都在经历快速而显著的发育变化。我们总结了目前对与理解幼儿口吃相关的各种发育轨迹的认识。我们还提出了理论和实验方法,我们认为这些方法对于更快速地为更有可能持续口吃的学龄前儿童开发更好、更有针对性的口吃治疗方法将是最佳的。
