The effects of dopamine on developmental stuttering was studied in a 44 year old man with developmental stuttering and Parkinson's disease during three levodopa "on" periods and three "off" periods. When compared with the "off" periods, during the "on"' periods he demonstrated an increase of speech dysfluencies. These findings lend support to the dopamine hypothesis of developmental stuttering.
在一名患有发育性口吃和帕金森病的44岁男性患者的三个左旋多巴“开”期和三个“关”期,研究了多巴胺对发育性口吃的影响。与“关”期相比,在“开”期他表现出言语不流畅性增加。这些发现支持了发育性口吃的多巴胺假说。
