There is an 82-year-old Mr. Doak who suffers from Alzheimer's disease. As the disease progresses, he confines himself more and more seriously, with no interest or ability to talk to others. However, everything changed when he joined a local singing group. His wife, Joan, said singing helped as he gradually stepped out of his own little world, his personality began to change and he began to talk to people.

Music therapy, as a form of treatment for geriatric diseases and delaying aging, is very common in developed countries. In nursing homes across the western United States, music therapists are most popular. Each of these elderly people in their 80s to 100s, all in wheelchairs, happily holds a special musical instrument - a single-note "sound block", playing according to a tune pre-arranged by the therapist. Whichever old man the therapist points to, he clicks the "sound block". The beautiful melody like a carillon flows out from the old man's blows. The elderly people all concentrated their energy, waiting for the rhythm assigned by the therapist, and swayed their bodies to match the rhythm of the music. After the song was played, everyone's face showed expressions of happiness and satisfaction. The nurse at the hospital said that these elderly people usually lose their ability to move and can only passively obey and rely on others. Only in music therapy can they actively exert themselves, so this is the most popular form of treatment in nursing homes.

Psychological research shows that musical activities are extremely orderly behaviors that help coordinate the body and mind and establish harmonious interpersonal relationships. At the same time, music can transcend consciousness and directly affect the unconscious. Therefore, for patients with Alzheimer's disease, music therapy is an effective and easy-to-accept method.

Those friends who do not suffer from Alzheimer's disease should treat aging correctly, take the initiative to gain understanding and consideration from their families and younger generations, arrange as rich a life as possible, and actively participate in music activities, such as singing, playing musical instruments, Dance activities etc.
