A person with Alzheimer’s disease may suffer from aphasia as a symptom of the disease, accelerating the patient’s lack of communication with his environment and therefore increasing social isolation. The present work investigated the music therapy process with a person with Alzheimer’s disease and aphasia as a symptom of their dementia, focusing on the 10 sessions that were carried out on language treatment and communication between the music therapist and the patient, addressing the effort towards vocalization of words, reading and comprehension of texts and conversations. A slight evolution was observed in the improvement of the repetition of words, of the intention in the communication and of the participation regarding the results, they indicate an improvement of the patient in the evolution of the aphasia. However, these results were not significant enough to be able to affirm that music therapy is a key element in slowing down aphasia as a symptom of Alzheimer’s disease
