Abstract	We reported a patient with crossed aphasia after a right putaminal hemorrhage. Two months after the onset, the patient was mute except for a small amount of the utterance of non-words. Then, 3 to 4 months after the onset, the patient's speech expression developed into non-meaningful recurrent utterances such as "nandeko" and "dendeko." The recurrent utterances were monotonous and aprosodic. In the 5 to 10 month period after the onset, the speech expression further developed into a mixture of non-meaningful and real word recurrent utterances. The repeated real word of the patient was "dakara" (which means because in Japanese), and the two types recurrent utterances were frequently produced simultaneously, such as "dakara nandeko nandeko nandeko," with rich prosody for the emotional expression. We discussed the aprosodic non-meaningful recurrent utterance of the patient originated form the residual language function of the dominant hemisphere. On the other hand, the development of the non-meaningful and real word recurrent utterances with rich prosody may be attributed to the improvement of the dysfunction of non-dominant hemisphere.
