Music therapy for non-fluent aphasia is a method for treating patients who have lost the ability to speak after a stroke or accident. Non-fluent aphasia, also called expressive aphasia, is a neurological disorder that deprives patients of the ability to express language. It is usually caused by stroke or lesions in Broca’s area, which is a language-dominant area responsible for speech production in the left hemisphere. However, lesions in Broca’s area only affects patients’ speech ability, while their ability to sing remains unaffected. Since several studies have shown that right hemispheric regions are more active during singing, music therapy involving melodic elements is deemed to be a potential treatment for non-fluent aphasia, as singing might activate patients’ right hemisphere to compensate with their lesioned left hemisphere. Aside from singing, many other music therapy techniques have also been attempted and the effectiveness of some techniques is shown. Although there are many possible explanations for the mechanism of music therapy, the underlying mechanism remains unclear, as some studies indicate contradictory results.
